Hello and welcome to this Argos Multilingual webcast. In this webcast we\'ll explore what Simplified Technical English is and its benefits. So what is Simplified Technical English? Simplified Technical English, often abbreviated to STE, is a system of controlled writing based on the principles of the ASD STE 100 standard. The standard was developed by the Aerospace and Defence Industries Association in the 1970s in order to simplify aircraft maintenance documentation and eliminate safety risks introduced by non-native mechanics working on aircraft worldwide. STE is a regulated standard that we have adapted to suit other industries. Deviations are required because the original standard was not designed for industries outside of aerospace. At Argos, we\'ve taken the core principles of STE, including rules, vocabulary, and dictionary building, and made them applicable to all content. This means we can help companies in multiple industries, from banking to medical, implement STE-like processes and put them to use over all types of documentation, from technical, and even in some cases, to marketing. The original STE standard follows 57 language rules. They limit the ways in which authors can create content and they help to enforce controlled writing. These rules include vocabulary restrictions with a core vocabulary of about 900 words. But there\'s the option to have thousands more company-specific terminology and names meaning a personalised dictionary for any industry where each word normally only has one meaning, helping to avoid ambiguity. This is especially important when you\'re writing instructions with commands and using words like close that can have multiple meanings, or technical words like engage that is better substituted with start. In critical situations, this type of ambiguity creates risk. STE helps to eliminate that risk. So why simplify, and why simplify English? This is because English is the most popular business language. Of course, there are more Chinese speakers in the world. but most are in a single market. English, on the other hand, is used worldwide, often by people whose native language is not English. This makes English very prone to mistakes and inconsistencies. Writers often explain their ideas in complex ways, creating a breeding ground for ambiguity and mistakes. This ambiguity can then actually be made worse by a large English vocabulary. There are many complex grammar rules, synonyms, and even mutually exclusive words like flammable and inflammable. Plus, it\'s part of human nature to write too much. Pride of authorship leads people to overwrite and overwhelm the reader with too much content. With STE, though, every word you write is controlled. You can\'t use a word unless it\'s approved. STE\'s rules also control the way you write. For example, sentence length is controlled, meaning you typically can\'t write more than 25 words per sentence. Hence, STE is great for cutting down your content, often by as much as 25%. This reduces the words that need to be published or translated. There are also more repetitions, content is easier to understand for the translator. All this makes translation faster. What\'s more, if you have a service call centre, another side benefit is that you\'ll receive fewer calls from confused customers. People will be able to read and follow the instructions easily, greatly reducing the need for call support. As well as saving on publishing and translation costs, All of your content will be consistent in style and vocabulary, and your writers will use fewer words. Their work speed should increase too. Your docs will avoid common problems such as where a device is called a device on one page, a unit on another, or a machine on the third, confusing the reader. STE can help you create modular content for content management systems. So what is the overall cost reduction from using STE? Of course, this does depend on the type and quality of documentation you already have, but you can get up to a 25% volume reduction, which can mean up to 35% reduction in translation costs. The STE standard contains seven golden rules, which we\'ve adapted to suit all industries. For example, rather than writing in a passive voice, saying things like, when using this device, always make sure to first extend the antenna in an upright position, STE forces you to write in an active voice, Using an active voice, the earlier sentence becomes, always extend the antenna when using the device. This mostly applies to instruction type content, where you should always use the active tense. To eliminate convoluted language, STE forces you to keep procedural sentences shorter than 20 words and descriptive sentences to fewer than 25 words, as well as less than six sentences per paragraph. The idea is to explain and move on. This actually forces the writer to explain ideas more slowly in a measured fashion rather than all at once in a single long sentence. STE uses a dictionary of only approved words which, although allowing for some synonymy, encourages each word to have only one meaning. The last two rules are about paying attention to the reader. Make sure your reader is not confused with your content. STE helps to control your word choice selection and writing style, even voice. Because of this, STE can adapt to technical, legal, financial, or even marketing content. So what\'s needed for an STE-like implementation? It\'s not enough simply to read about STE. Your team will need hands-on practice, training, and experience. Argos can put you in touch with experienced industry trainers who go over all the key aspects of the standard, illustrate practical approaches, and help your team to practice using their own content. Once your writing team has the basics, The next step is to build a terms dictionary for your content. You\'ll need to publish an internal list of all the preferred names you want to use and a thesaurus of all the unapproved words you don\'t want people to use when writing. Then, you\'ll adapt a style of writing that will be modified for your company and industry. Once complete, your team is ready to start writing in simplified English. When writing, you can use Checkr software that can highlight problematic sentences and poor word choice. We\'ll explore Checkr\'s more later on in this webcast. Lastly, Argos can offer supporting services and consultancy, including revision, follow-up trainings, assistance in migration between languages, or even CMS integration. Once your team has been trained, the next task is to build a dictionary. To do that, we first need to define an approved terminology list. Argos has a set of tools that we use for text mining. The trick here is to identify the technical terms used in your documentation. That\'s especially true for compound nouns like hardware or painkiller. or the term text mining. They\'re regulated by the standard and should be no longer than four words in length. The standard doesn\'t try to change existing standard terminology. There is room for discretion on the part of the writer. The standard simply helps writers to keep each term below four words. During text mining, we\'ll try to identify what those words are, expose them, and add them to the dictionary of the checking tool. Once the dictionary is built, it belongs to the customer who then maintains it. This means that your writing department keeps a company-specific dictionary that they consult and add to, and spread across the company. Let\'s look now at some examples of how writing can affect your documentation. Here you can see how a typical instruction manual is written. Notice how it starts out on the left, naming all the products MP3250, etc. But in the new STE version to the right, the text is reduced by simply referring to the different products as a projector. In the text on the left, the instructions are lengthier and, in some cases, redundant. However, once ST principles applied, the same text can be trimmed down by over 30% while keeping all the relevant information intact. The amount of word reduction will differ based on different content types and its original quality, but you might typically expect up to 30% reductions. All word count reductions, however, directly influence your bottom line. Anytime you reduce text volume, you decrease your publishing and translation costs. When you look at the content on the right, you\'re not actually translating what\'s on the left, instead you\'re clarifying it and that\'s the whole point of STE. So while this example is from Consumer Electronics Manual, it illustrates STE in action and how it can be applied to instruction type documentation from any manufacturing, IT or even medical industry. As we mentioned earlier, once STE is implemented, we can help you choose a checker tool that\'s right for your business. Checker tools work alongside the writer in a similar way to spell checker tools like Microsoft Word. The software automatically highlights problematic word choices. For example, it\'ll highlight when you use verbs like rotate, where turn is the approved term. The software will propose changes and highlight poor sentence structure, but it\'s ultimately up to the writer to decide whether the sentence is in fact correct or not. The point is, Checkr software is there to help rather than to do the work. It\'s like a coach that offers advice, but it won\'t do the work for you. Overall, it helps to speed up the writing process while making sure that SDE rules are followed across your content. Argos will be happy to help you decide on the right checker software for your publishing program. We can help you to determine your objectives and establish your technical requirements, and based on your needs, we can propose a few options. Of course, you can write in SDE without checker software just so you can write documents without using a spell checker, but checker software spots all those little mistakes which end up being noticed and which cause problems. So, to summarise, we spoke of STE implementation, what effect it can have on your business, we talked about customising STE for your industry, we can help to integrate STE with your authoring environment, including content management systems, and we can help to choose the right checker tool for your needs. Overall, with STE, you will clarify your content, reduce your printing and publication costs, and that will end up producing savings on translation. thank you for watching our webcast for more information on how we can help your business to grow visit us at [[www.argosmultilingual.com]](http://www.argosmultilingual.com) In the video titled \"Simplified Technical English\" from Argos, the presenter discusses the concept and benefits of Simplified Technical English (STE). Here's a summary of the key points covered: Overview of Simplified Technical English (STE) - **Definition**: STE is a controlled writing system based on the ASD-STE100 standard, developed in the 1970s by the Aerospace and Defense Industries Association to simplify aircraft maintenance documentation and reduce safety risks associated with non-native English speakers working on aircraft - **Adaptation**: While originally designed for aerospace, Argos has adapted STE principles for various industries, including banking and medical fields Core Principles of STE - **Language Rules**: The original STE standard consists of 57 language rules that limit how content can be created, promoting clarity and reducing ambiguity. The vocabulary typically includes around 900 core words, with the option to incorporate additional industry-specific terminology - **Clarity and Precision**: Each word in STE generally has one meaning, which is crucial for writing instructions or commands where multiple meanings can lead to confusion Benefits of Using STE - **Reduction in Ambiguity**: By simplifying language, STE minimizes mistakes that often arise from complex grammar and vocabulary, making it easier for non-native speakers to understand instructions - **Efficiency in Documentation**: Implementing STE can lead to a reduction in document length by up to 25%, which also translates to lower translation costs---up to 35% savings - **Improved Customer Communication**: Clearer instructions reduce confusion among customers, leading to fewer support calls and better user experiences Implementation Steps - **Training and Practice**: Teams need hands-on training to effectively implement STE. Argos offers resources and trainers to assist with this process - **Dictionary Development**: Companies should create an internal dictionary of approved terms and maintain it for consistency across documentation Conclusion The video emphasizes that adopting STE not only clarifies content but also reduces printing and publication costs, ultimately leading to significant savings on translation expenses. For further assistance, Argos encourages businesses to reach out for tailored solutions in implementing STE effectively **Introduction : \*\*Welcome to the Second Course: \"The English Alphabet: Letters, Pronunciation, and Tips for Remembering Them\"\*\*** Welcome back, everyone! I hope you\'re all doing well and ready for today\'s session. In this course, we\'re diving into something that seems simple but is super important: \"The English Alphabet, Pronunciation, and Tips for Remembering Them.\" We\'re going to break it all down, make it fun, and see how mastering pronunciation can help you improve, especially when it comes to learning Technical English. Just like in French, English also has 26 letters from A to Z. But here\'s the twist---the way we pronounce these letters in English is different, and that's where things can get tricky. We sometimes read English words the way we're used to in French, but today, we'll focus on learning the right way to pronounce each letter using phonetics. \*\*Why Focus on Pronunciation?\*\* Because the Pronunciation is the foundation of English, and mastering it can make a huge difference in how easily you communicate. If you can pronounce the letters correctly, you\'ll find it much easier to say words properly. This is especially important in technical English, where clear pronunciation is key to avoiding misunderstandings. In all fields like science, medicine, or engineering, mispronouncing technical terms can lead to confusion or errors. For example, the difference between \"data\" and \"datum\" or \"parameter\" and \"perimeter\" can change the meaning entirely. By learning to pronounce the alphabet and words correctly, you're setting yourself up for success in technical communication. In the next part of the course, we\'ll dive into how English sounds are constructed using IPA (International Phonetic Alphabet) symbols, which will help you further improve your pronunciation and understanding of the language. For now, focus on the basics of the alphabet, and let's move step by step. Let\'s get started by seeing the first video for today. Please listen carefully! After watching the video, it\'s time to break down what we\'ve learned about the pronunciation of the English alphabet. Let's start by reviewing the phonetic pronunciations of each letter from the table: Now, let's focus on the key differences between similar letters, such as \*\*J\*\* and \*\*G\*\*. \*\*J\*\* is pronounced \[dzei\] as in "DJ," while \*\*G\*\* is \[dzi\] like in "GI." Another common difference occurs with the letter \*\*Z\*\*: in British English, it is pronounced \[zed\], but in American English, it's pronounced \[zi\], like \"zee.\" - These differences are essential for correct pronunciation. For example, a word like \"zebra\" will sound different if pronounced in British or American English. So, practicing the alphabet using the correct phonetics will help you avoid common mistakes. - Next, let's talk about the challenges that arise when letters are combined. For instance, the letter \*\*I\*\* is pronounced \[ai\], but when it appears in words like \"fine\" and \"pig,\" it has different sounds. In \"fine,\" it\'s pronounced \[faine\], while in \"pig,\" it\'s spelled and pronounced \[pig\]. This shows that the pronunciation of a letter can change depending on the word and surrounding letters. - This brings us to phonemes---these are essential tools for learning how letter combinations are pronounced in English. There are 44 phonemes in English, 20 of which involve vowel sounds, and the rest are for consonants. Phonemes will guide us in reading words accurately by showing us how different letter combinations sound. - **Now, before we move on, does anyone have any questions?** If not, we'll continue exploring the 44 phonemes and how they help with pronunciation. - A **phoneme** is the smallest unit of sound in a language. Each phoneme makes a difference in how a word is pronounced and can completely change the meaning of a word. In English, phonemes include short and long vowels, consonants, and specific sounds like \"th\" and \"sp.\" For example, think of the words \"bat\" and \"pat.\" By changing just one phoneme, /b/ to /p/, the meaning of the word changes entirely. This shows how critical phonemes are in distinguishing between words. English has 44 distinct phonemes that we use to pronounce words correctly. - The term phoneme comes from the French word \"phonème,\" which is derived from the Greek \"phōnēma,\" meaning \"a sound made.\" These 44 phonemes form the foundation of pronunciation in English, helping us understand how words should sound and what they mean. - Now, let's talk about the **International Phonetic Alphabet (IPA)**. The IPA is a set of symbols that represents the different sounds in English. - I understand that learning what seems like an entirely new alphabet can be frustrating, but it's essential for knowing how to pronounce English words correctly. The IPA helps you see and recognize which sound you need to make. Instead of just looking at the letters in a word and trying to pronounce them, you'll be able to see the actual sounds that combine to produce the word and pronounce it. - **Does anyone have any questions about what phonemes are or how they work?\"** Now, let\'s explore the **IPA** chart and understand it. This chart illustrates the 44 sounds of English. You'll notice that some symbols resemble English letters, making it easier to remember. For instance, the letter B represents the /b/ sound, and K represents the /k/ sound. However, other sounds have different symbols, such as the one for /ʃ/ (the \"sh\" sound) which can be represented by various English letters in words like *show*, *relation*, *passion*, and *chef*. The IPA is divided into two sections: - The **top half** shows the English vowel sounds, including both monophthongs and diphthongs. - The **bottom half** showcases the English consonant sounds, divided into voiced and unvoiced. Let's break down each type and learn how to pronounce them effectively. So the vowels sounds and Let's start with **\*\*short phonemes\*\*.** These are single vowel sounds pronounced quickly. Here's a list of common short vowel sounds along with tips for pronunciation: - \*\*/ɪ/\*\* as in \*\*ship\*\* \[ʃɪp\]: To pronounce this sound, relax your mouth slightly, and keep your lips unrounded. It's a quick sound, as if you're surprised. - \*\*/ʊ/\*\* as in \*\*good\*\* \[ɡʊd\]: For this sound, round your lips as if you're blowing out a candle. It's slightly longer than /ɪ/, but still quite short. - \*\*/e/\*\* as in \*\*bed\*\* \[bɛd\]. - \*\*/ə/\*\* as in \*\*about\*\* \[əˈbaʊt\]: This is the \*\*schwa\*\* sound, which is very relaxed. Your mouth should be in a neutral position, as if you're mumbling. - \*\*/æ/\*\* as in \*\*apple\*\* \[ˈæpəl\]: Open your mouth wide and drop your jaw slightly. - \*\*/ʌ/\*\* as in \*\*up\*\* \[ʌp\]: Keep your mouth open and relaxed, as if you're about to say \"ah!\" - \*\*/ɒ/\*\* as in \*\*not\*\* \[nɒt\]: Now, let's move on to **\*\*long phonemes\*\*.** These vowel sounds are held longer than short vowels and are denoted with a colon (:) in phonetic transcription. Here are some common long vowel sounds: - \*\*/i:/\*\* as in \*\*sheep\*\* \[ʃi:p\]: - \*\*/u:/\*\* as in \*\*grew\*\* \[gru:\]: - \*\*/ɜ:/\*\* as in \*\*bird\*\* \[bɜ:rd\]: - \*\*/ɔ:/\*\* as in \*\*door\*\* \[dɔ:r\]: - \*\*/ɑ:/\*\* as in \*\*car\*\* \[kɑ:r\]: - \*\*/i:/\*\* as in \*\*eagle\*\* \[i:gle\]: - Finally, let's discuss \*\*diphthongs\*\*. Diphthongs are complex sounds that begin with one vowel and glide into another within the same syllable. Here are some examples: - \*\*/iə/\*\* as in \*\*ear\*\* \[iər\]: Start with /ɪ/ and glide into /ə/. - \*\*/ei/\*\* as in \*\*train\*\* \[treɪn\]: Begin with /e/ and move to /ɪ/. - \*\*/ʊə/\*\* as in \*\*your\*\* \[jʊər\]: Start with /ʊ/ and glide to /ə/, - \*\*/ɔɪ/\*\* as in \*\*boy\*\* \[bɔɪ\]: Start with /ɔ/ and glide to /ɪ/. - \*\*/əʊ/\*\* as in \*\*coat\*\* \[kəʊt\]: Begin with /ə/ and glide to /ʊ/. - \*\*/eə/\*\* as in \*\*hair\*\* \[heə\]: Start with /e/ and glide to /ə/. - \*\*/aɪ/\*\* as in \*\*by\*\* \[baɪ\]: Start with /a/ and glide to /ɪ/. - \*\*/aʊ/\*\* as in \*\*now\*\* \[naʊ\]: Start with /a/ and glide to /ʊ/. - \*\*Introduction to Consonant Sounds:\*\* Now, let's shift our focus to consonant sounds. Compared to vowels, consonants are a bit easier to manage. Consonant phonemes fall into two main categories: \*\*voiced\*\* and \*\*unvoiced\*\*. **- \*\*Unvoiced consonants\*\*** are produced by pushing air through your mouth without vibrating your vocal cords. If you put your hand in front of your mouth while pronouncing sounds like \*\*p, t, k, f, s, ʃ (sh), θ (th)\*\*, you'll feel the air. For example \[p\] (as in \*pen\*), \[t\] (as in \*table\*), \[k\] (as in \*key\*), \[f\] (as in \*fire\*), \[s\] (as in \*sick\*), \[ʃ\] (as in \*shop\*), \[θ\] (as in \*think\*), \[tʃ\] (as in \*chips\*) **- \*\*Voiced consonants\*\*,** on the other hand, make your vocal cords vibrate. To feel the vibration, gently place your hand on your throat while making sounds like \*\*b, d, g, v, z, ʒ (zh), ð (th)\*\*. You won't feel as much air, but you'll notice the buzzing. For example : \[b\] (as in \*ball\*), \[d\] (as in \*dog\*), \[g\] (as in \*green\*), \[v\] (as in \*video\*), \[z\] (as in \*zebra\*), \[ʒ\] (as in \*vision\*), \[ð\] (as in \*this\*), \[dʒ\] (as in \*jam\*) **Lets see Other voiced Consonants like** \[m\] (as in \*man\*), \[n\] (as in \*next\*), \[ŋ\] (as in \*sing\*), \[l\] (as in \*love\*), \[r\] (as in \*run\*), \[w\] (as in \*win\*), \[j\] (as in \*young\*), \[h\] (as in \*house\*) The key is, once you can recognize and produce these English sounds, you\'ll be able to pronounce any new word by breaking it down into its correct sounds. This will also help you apply the right syllable and sentence stress, making your speech clearer and more natural. The question must be, how do you memorize all these sounds and symbols? Just By practicing! Soo Let's practice together right now, and you'll see how quickly you improve! Thanks for practicing with me! You\'ve all done an amazing job. Now, let's dive into the second part of our lesson, **\#\#\# Syllables and Stress: Understanding the Rhythm of English** After covering vowel and consonant sounds, let's focus on how these sounds come together in words, specifically looking at syllables and stress. In English, pronunciation isn't just about saying each sound correctly; it's also about emphasizing certain parts of a word. Every word consists of syllables, which are the fundamental units of pronunciation. A syllable can be as simple as a single vowel, like \'a\', or a combination of a vowel and one or more consonants, such as \'skip\' (which has one syllable but consists of three sounds: sk-i-p). To figure out how many syllables a word has, listen to its pronunciation rather than relying solely on its spelling. For example, \"household\" has two syllables, \"elephant\" has three, and \"hippopotamus\" has five. Not all syllables carry the same weight. Some syllables are stressed, meaning they are pronounced more strongly or clearly, while others are unstressed and spoken more softly. This stress pattern gives English its natural rhythm, making speech smoother and more understandable. For instance, in the word \"about\" \[əˈbaʊt\], the second syllable is stressed, so we emphasize it more than the first syllable. Understanding syllables and stress will help you sound more natural and confident in your English pronunciation. By recognizing how sounds combine with stress patterns, you can enhance both your clarity and fluency when speaking. For two-syllable nouns and adjectives, the stress usually falls on the first syllable, as seen in words like \"doctor\" and \"happy.\" In contrast, two-syllable verbs typically stress the second syllable, as in \"decide\" and \"explain.\" Three-syllable words can vary, but they often place stress on the first or second syllable, like in \"beautiful\" or \"tomorrow.\" Words ending in -tion, -sion, or -cian often have stress on the second-to-last syllable, as in \"information,\" while words that end with -ic usually stress the second-to-last syllable too, like \"scientific.\" For words with three or more syllables that end in -y, the stress generally falls two syllables before the end, such as in \"biology.\" Finally, it\'s important to remember that stress involves a contrast between stressed and unstressed syllables. Stressed syllables are pronounced with more emphasis, while unstressed syllables are often reduced and spoken more quickly. Now, let's watch a final video to see how we can easily apply these concepts in practice! \#\#\# Conclusion Thank you all for your participation in this course! I hope you found the lessons useful in enhancing your English pronunciation skills. If you have any questions or need clarification on any of the topics we\'ve covered, please feel free to ask. I encourage you to rewatch the videos we\'ve discussed, as they provide valuable insights and examples to reinforce what you\'ve learned. I will send three videos to the delegate that will help you review the course content further. Thank you once again, and I look forward to seeing your progress! Mechanical engineering is a branch of engineering that focuses on the design, analysis, and manufacturing of mechanical systems. This major is highly math, especially calculus, and physics based. One of the great things about mechanical engineering is that it is highly versatile in what you can do. Students who graduate as a mechanical engineering major can go into construction, automotive, heating and air conditioning, materials, robotics, work in the energy sector, combustion engines, and many more. Now besides mechanical engineering classes, you\'ll take a little bit of everything basically. You have to take a few electrical engineering classes to learn about the basics of circuits and possibly some of the basics of electronics as well. You have to do a little programming and become decently proficient in MATLAB, which is a software that allows you to create plots and graphs and do complicated math way beyond what your graphing calculator can do. You\'ll possibly have to do a welding class, then of course you have to take about two years of math, mostly calculus, and about one year of physics. Now the first main class of mechanical engineering would be statics, where you\'ll look at the physics of systems that aren\'t moving. This would be like looking at the forces and torques in something like a truss that holds up a bridge, where you have to analyze the forces that individual beams feel due to external forces. Then the next class would be dynamics, where you look at systems that are moving. It\'s similar to your high school physics class with projectile motion, momentum, energy, forces, and more, but is much more involved. You\'ll look at the motion of much more complex systems and have to find things like velocity, acceleration, energy, force, and more of different parts of that system. Then your third year, you\'d even take a more advanced version of this class where you\'ll look at these complex systems, but now in three dimensions. So as you can probably already see, mechanical engineering involves a lot of advanced physics. When you enter your third year, you\'ll take a course called Fluid Mechanics, and in this course you\'ll study the properties and mechanics of fluids such as air and water. This class is very calculus based. For example, you could study how the pressure of water changes as it flows through a set of pipes in a closed environment as height and pipe dimensions change. The principles to solve this are foundational for how your car brakes work. This class also includes the physics of how wind turbines work and why they are made the way they are so that they move as much as possible from any amount of wind. And you can analyze why different shapes are better or worse. And if airplanes interest you, you can even learn how wind flows over a wing to produce aerodynamic force, which also applies to car aerodynamics, which if optimized, increases cars\' MPG. You also take a class called thermodynamics, which deals with the relations between heat and other forms of energy, such as mechanical, electrical, or chemical. In this class, you\'ll study the combustion engine, which applies to cars, boats, and aircrafts, and you\'ll learn these engines in great depth and see how they are constantly making adjustments to make them more efficient. You\'ll go as far back and learn at how the first steam engine was created, and you\'ll learn how similar ideas are still being used in power plants today to produce energy to power your TV, turn on your lights, and power your appliances. You\'ll then take a vibrations class where you\'ll analyze the mechanical vibrations that occur in different objects. Think about if you were to drop a metal object. When it hits the ground, you might observe or even hear it vibrating. Well, in mechanical systems like planes, cars, satellites, and more that are moving but also contain parts like motors and engines that are also moving at very high speeds, it\'s important to analyze the system even down to the vibrations to ensure the system can withstand those vibrations that occur. Have you ever seen in movies a person make a high-pitched note and it causes something like a glass to shatter? That\'s because the sound is making the glass vibrate at just the right frequency called the natural frequency that makes it shatter. Buildings even need to account for this because in the case of an earthquake, the building will shake and vibrations will be created. This is actually a building in Japan that was structurally built to withstand high winds and strong earthquakes from causing strong vibrations. One thing they did was put something called a tuned mass damper near the top of the building, which weighs 728 tons, and is something that is engineered to reduce mechanical vibrations that can actually save the building from destruction during natural disasters. In 1940, the Tacoma Bridge collapsed, and what they found afterwards was that vibrations occurred due to interactions between the bridge and the wind, which just kept amplifying until it fell apart. Like most mechanical engineering classes, this one is highly calculus-based because you have to model very complex systems and motion. Then you\'ll take some design classes, and these are kind of a combination of materials engineering and mechanical engineering, where you\'ll look at the strength and durability of different materials, mechanisms, and structures. As a mechanical engineer, someone might tell you they need a certain motor to make a million cycles without breaking. or maybe they needed to run for 10 years without breaking. This could even apply to just how much weight can a beam support before breaking and how much stress is it subject to with a certain amount of weight. Now there are a few concentrations within mechanical engineering. A few specific ones include heating and ventilation, air conditioning and refrigeration, or HVAC as it\'s called, then mechatronics, and manufacturing. Now HVAC goes into more vehicle and indoor comfort using your knowledge of fluids, thermodynamics, and heat transfer. An HVAC concentration leads to working on maintaining heat and ventilated air in something like a large commercial building, cars, apartment buildings, homes, hospitals, hotels, and more. Where you\'ll have to understand how heat travels throughout the building and different materials. When you see those ducts in large buildings, Those have to be carefully placed in order to ensure comfort throughout the whole building by knowledge of thermodynamics and airflow. Now it may not seem like it, but seeing how these systems actually work can actually be pretty involved. Then mechatronics is like the combination of mechanical engineering, electronics, and some computer engineering. As a mechanical engineer, when it comes to robotics, you\'d be able to build the robot structurally and make sure it can withstand a certain amount of force. But with mechatronics, you dive more into also the programming and circuiting of the robot. So with a mechatronics concentration, you basically have all the sub-disciplines necessary to build, circuit, and program a robot. And this has applications in embedded systems, sensing and controls, robotics, and more. Now the manufacturing concentration is a little more broad because you can learn things from the design of a part to the actual materials used for the part. Manufacturing might involve learning techniques that help you predict when a certain part will fail. This major will be helpful in teaching you that slight alterations in design or material of a part can have a drastic impact on the overall price, which becomes an important component in the design and manufacturing of parts related to profit margins and running a business. Now these are just some examples of concentrations, but there are many more sub-disciplines, and as a mechanical engineer you have a lot of flexibility. As a mechanical engineer, you could work on cars. But to be more specific, you could work on improving the engine to make it more efficient. You could work on the suspension of the car to ensure it can handle the forces that the car is subject to. Like could it handle going over a speed bump too fast? Or you could do crash testing and look at the materials and shape of the car to see what it can withstand and how it would affect a person inside. Or you could maybe analyze how air flows over or through the car and optimize its aerodynamics to make it go faster from knowledge of your fluids classes. And this could even be applied to planes or drones. A mechanical engineer could also work with biomedical engineers on things like prosthetic body parts. They might need to help make sure the mechanism is strong enough to withstand the forces they\'ll have to put up with, or they might have to decide what\'s the best material to use. Mechanical engineers can also work on alternative forms of energy, like on wind farms, hydroelectric, solar, and more. They can work on satellites and use mechanics to analyze the vibrations during high acceleration, or they can use thermodynamics to analyze the temperature differences that the satellites go through as they orbit the Earth. They can work on robotics, weaponry, machines, and the list just goes on. As you can see, mechanical engineers really have no limits to what they can see in their career.

I hope you're ready for another interesting part of our Technical English course. Today, we're diving into an essential field: Mechanical Engineering. In this first part, we'll look at key terms and real-life examples to see how mechanical engineering drives innovation and improvements in everyday life. Then, in the second part, we'll work on some specific grammar and vocabulary that'll strengthen your language skills for this field. Alright, let's get started with the basics and according to the video: What is mechanical engineering? Mechanical engineering is all about designing and working with machines and systems that make everyday life easier. Think of it as the branch of engineering that brings ideas to life, from designing small parts like gears in a clock to big engines in airplanes. It\'s about taking ideas and turning them into functional, reliable, and useful tools that help people. If you've ever wondered how a car works or how machines make products in factories, that's all thanks to mechanical engineering. At its core, it's the science of motion, energy, and force. Mechanical engineers use these principles to design, analyze, and manufacture everything. They're problem solvers who use creativity and analysis to turn ideas into reality. Moving on, \*Why is mechanical engineering so versatile? Mechanical engineering gives you the skills to work in many different areas. For example, if you're interested in cars, you could work in the automotive industry, designing car engines or even creating parts for electric cars. Or, if you're interested in how buildings stay warm or cool, you could work in HVAC---heating and air conditioning---creating systems that keep buildings comfortable in all weather. They can also delve into robotics, developing automated systems for manufacturing or healthcare. Additionally, there\'s a growing demand in renewable energy, where engineers contribute to wind, solar, and other sustainable technologies. This variety of options means that mechanical engineers can align their careers with their interests while making a meaningful impact in different sectors. Let's talk about \*what classes are essential for mechanical engineers\*. The basics are math and physics because they help engineers calculate how things move and work together. Engineers also study programming, electrical engineering, and specific subjects like statics (which deals with things that don't move, like bridges) and dynamics (which deals with things that do move, like vehicles). For instance, statics would help you design a bridge that can hold weight, while dynamics would help you understand how a car's parts move as it drives. \*What is MATLAB, and why do engineers need it?\* MATLAB is a powerful tool for engineers that goes beyond calculators. Imagine you're working on a project where you need to handle tons of data or run calculations that a regular calculator just can\'t keep up with. MATLAB is like a super-powered calculator, but it's also way more than that---it's a complete environment for solving complex engineering problems. For example, suppose you\'re testing the design of a new part for a machine. With MATLAB, you can build a virtual model of that part and see how it might react under different conditions, like weight or speed, without physically building anything. You can test various factors to see how they impact performance---saving time, money, and materials. MATLAB also allows you to create visual representations like graphs or animations. So if you're looking at how a mechanical part moves, you can actually \*see\* the movement in a simulation. Another huge advantage is data analysis. Imagine you've run an experiment and collected tons of measurements. MATLAB can quickly analyze all this data, spot trends, and help you make decisions based on what you see. This capability is key when you need to validate your designs or ensure that your results are consistent. *\"Imagine MATLAB as your go-to workspace for tackling complicated problems in an easier way. When you open MATLAB, the first thing you'll notice is the \*Command Window\*. This is where you type commands, like a giant calculator. For example, if you need to solve a math problem, you type it here, and MATLAB gives you the answer right away.* *But MATLAB is much more than a calculator. It can create entire \*scripts\*, which are like mini-programs you write to handle big tasks. Let's say you're dealing with a hundred measurements from an experiment. Instead of working with each number one by one, you write a script to handle everything automatically. This saves a ton of time and reduces mistakes.* *Another cool part is the \*workspace\*. Think of it like a clipboard that holds your data, numbers, and calculations as you work. You can go back, check, and use this data whenever you need it, without retyping or recalculating anything.* *MATLAB also makes it easy to visualize results. You can create graphs and plots with just a few commands. So, if you're testing how a machine part will perform, you can model it in MATLAB and see the results in a graph before even building it.* *So, in short, MATLAB lets you work smarter with big tasks: you solve equations, process large amounts of data, create visual models, and save all your work in one place. This will be essential when you're doing real engineering projects.* Now, \*what's the focus of statics and dynamics in engineering?\* Statics looks at systems that stay in one place, like bridges or buildings, making sure they're stable and can hold weight without moving. Dynamics, on the other hand, is about systems that move, like the gears in a machine or the engine parts of a car. Understanding both is important because some parts of a machine stay still while others move---just think of a rollercoaster, where some parts are fixed, but the cars need to move smoothly along the track. \*Why is fluid mechanics important for engineers?\* Fluid mechanics studies how liquids and gases flow. This might sound simple, but it's used to design things like car brakes, where fluid transfers force from the brake pedal to the wheels, or wind turbines, which need to understand air flow to work efficiently. Without knowing how fluids behave, engineers wouldn't be able to create safe and effective systems in cars, planes, or even air conditioners. Then there's \*thermodynamics\*, which involves studying heat and energy. Engineers use thermodynamics to make engines and other systems more efficient. For example, when designing an engine, they need to understand how to convert heat into movement without wasting energy. So, whether it's for cars, airplanes, or HVAC, thermodynamics helps make energy use more effective. Mechanical engineers can specialize in areas like HVAC, mechatronics, and manufacturing. \"HVAC\" stands for \*Heating, Ventilation, and Air Conditioning\*. It's a system that controls the temperature, humidity, and air quality in indoor spaces, like buildings, homes, and even vehicles. Think of it this way: HVAC is what makes a space comfortable and safe to be in, no matter what's happening outside. It's responsible for warming up the room in the winter, cooling it down in the summer, circulating fresh air, and filtering out pollutants or allergens. Mechanical engineers often work on designing and improving HVAC systems to make them more energy-efficient, quieter, and better at maintaining a comfortable indoor environment. \*Why do engineers need to know about vibrations?\* Vibrations can be destructive if they're not controlled. Imagine a bridge or a car that shakes too much---it wouldn't be safe. Engineers study vibrations to ensure that structures and machines can handle stress without breaking. For example, tall buildings use technology to dampen vibrations from winds or even earthquakes, making them safer in extreme conditions. **Mechanical Engineering in Action: Key Impact Areas** Alright, let\'s explore some specific areas where mechanical engineers make a big impact. \#\#\# Automotive Industry Mechanical engineers are like the brains behind car design. They think about everything that goes into a car---like the engine, fuel usage, and safety. Imagine you're working on a new car engine. It needs to be powerful but also not waste a lot of fuel. Mechanical engineers find ways to make it use less fuel and produce fewer emissions, which is better for the environment. They also make the car's shape smooth so it cuts through the air easily. This way, the car can go faster with less fuel. For safety, they design things like airbags and seatbelts and make sure these parts work correctly to protect people during accidents. \#\#\# Renewable Energy Mechanical engineers also help create clean energy systems, like wind turbines and solar panels. Take a wind turbine, for example---the big fan-like structures you might see in fields. Mechanical engineers design the blades (those big wings) to catch the wind and spin more efficiently, so they can generate more electricity. For solar panels, they work on ways to absorb more sunlight to produce more power. In hydroelectric systems (using water to create power), they design parts that can handle the water flow well. All these designs help us get cleaner energy in ways that are efficient and cost-effective. \#\#\# Robotics Mechanical engineers also build robots, making sure they're strong and reliable. Think of a robot in a factory that picks up heavy things. The engineer designs the robot's arm to be strong enough to lift those objects without breaking. They also make sure it doesn't wear out too fast, so it can work for a long time. Some mechanical engineers work in \*mechatronics\*, which is a mix of mechanics, electronics, and computer science. They think about how the robot will move, what it can carry, and how it will "talk" to computers or sensors, which allows robots to do things accurately, whether in factories or even in hospitals. **Biomedical Engineering** In biomedical engineering, they help create medical tools and devices that improve health. Imagine designing a prosthetic limb---a replacement for someone's leg or arm. Mechanical engineers work to make sure it's strong and comfortable, so the person can walk or move naturally without pain. It's a way to help others and directly improve lives. **Aerospace and Defense** In aerospace, they work on everything from airplanes to satellites. Think about the engines of an airplane---mechanical engineers design them to be powerful yet lightweight to help the plane use less fuel. If you love the idea of space or flying, this field has some amazing projects waiting for you! This mix of creativity, design, and problem-solving makes mechanical engineering a powerful part of modern industry. **So, what do you need to succeed?** Mechanical engineers rely on a mix of math, hands-on skills, problem-solving, and teamwork. Here are some key skills you'll develop in your studies: 1. **Math and Physics**: These subjects help you understand forces, energy, and movement---basic principles that help you solve real-world problems. For example, knowing how to calculate changes in pressure is essential for designing systems like heating or irrigation. 2. **Programming and Software**: Engineers use tools like MATLAB for complex calculations and CAD (Computer-Aided Design) for creating 3D models of parts or machinery. This software lets you test and refine your designs before they're built. 3. **Lab and Workshop Experience**: Labs are a chance to apply what you've learned and test ideas in real-life situations. For instance, you might learn how materials react under stress or try welding, gaining hands-on skills that will be valuable in any project. 4. **Critical Thinking and Problem-Solving**: Engineering is all about solving problems. Imagine you're designing a car part and need to make it lighter for fuel efficiency without losing strength. Problem-solving helps you think through options, like choosing materials or adjusting the design. 5. **Communication**: Engineers often work in teams, explaining ideas to people from different backgrounds. Clear communication skills are essential for sharing your findings and collaborating on projects. By building these skills, you'll be prepared for a variety of careers. Companies value the technical skills and flexibility that mechanical engineers bring to the table. NOUN : \"Alright, let\'s dive into nouns---one of the first things you probably learned in English! Nouns are everywhere in our language. Anything we can touch, see, smell, taste, hear, or even think about can be a noun. So, in this part of the course, we're going to cover what nouns really are, the different types, and how to use them effectively in sentences. Nouns are simply words that name people, places, animals, things, and ideas. Nearly every sentence you'll come across has at least one noun doing its part. Sometimes, nouns are subjects (like 'dog' in \*The dog barked\*), or direct objects, or even act as adjectives or verbs, depending on how they're used. For example, in \*basketball court,\* \*basketball\* acts more like an adjective describing the court. Now, nouns come in different types. The three we'll talk about today are: 1\. \*\*Proper Nouns\*\*: These are specific names of people, places, or things and always start with a capital letter. For example, \*Rose\* is a person's name, \*David\* refers to a specific person, and \*Louis Philippe\* is a brand name. 2\. \*\*Common Nouns\*\*: These are more general names for things---like \*city,\* \*river,\* or \*animal.\* 3\. \*\*Singular Nouns\*\*: These refer to just one person, place, or thing, like \*girl,\* \*dog,\* or \*van.\* In short, nouns are everywhere, and understanding how they function helps us structure clear, meaningful sentences. So, let's look closer at these types and get comfortable using nouns in different ways.\" \"Alright, everyone, let's jump into the concept of \*\*Word Formation\*\* in English. Word formation is what gives the English language its flexibility and creativity, allowing us to build new words from root words by adding certain elements. Whether it's turning a simple idea into a more complex one or shifting a word to a different meaning, word formation makes language dynamic and versatile. So, what exactly is \*\*word formation\*\*? It's the process of creating new words from existing words, often by adding syllables, parts of words, or combining words. This is done in several ways, and we'll break them down into four main types: 1\. \*\*Adding Prefixes\*\*: A prefix is a letter or group of letters added to the start of a word, often changing its meaning. For instance, prefixes like \*\*in-\*\*, \*\*un-\*\*, \*\*dis-\*\*, \*\*im-\*\*, and \*\*ir-\*\* can make a word negative or give it an opposite meaning. \- \*Examples\* include: \- \*Discipline\* becomes \*indiscipline\* \- \*Just\* becomes \*unjust\* \- \*Happy\* becomes \*unhappy\* \- \*Polite\* becomes \*impolite\* \- \*Legal\* becomes \*illegal\* Each prefix modifies the root word, giving it a new meaning, often implying 'not' or 'opposite of.' 2\. \*\*Adding Suffixes\*\*: Suffixes are letters or groups of letters added to the end of a word. This can change the word's form, sometimes turning it into a different word class altogether, like turning a verb into a noun. \- For example, \*happy\* can become \*happiness\* by adding the suffix \*-ness\*, which changes it from an adjective to a noun. 3\. \*\*Converting Word Classes\*\*: Sometimes, we can form new words by changing a word's part of speech without adding anything to it. This is known as \*\*conversion\*\*. For example: \- \*Drink\* can be both a noun (as in a beverage) and a verb (as in the action of drinking). \- \*Google\* started as a noun but is now also commonly used as a verb. 4\. \*\*Forming Compound Words\*\*: In this type of word formation, two words combine to create a new meaning. Think of examples like: \- \*Toothpaste\* (tooth + paste) \- \*Basketball\* (basket + ball) \- \*Mother-in-law\* (mother + in-law) These compound words bring together two separate ideas, often creating a totally new concept. Understanding these types of word formation will help you expand your vocabulary and understand how English words can change and adapt over time. Each method gives you the tools to make your language richer and more precise, allowing you to communicate with more clarity and creativity. Now, let's look closer at how these types work in sentences and real-world usage!\" \"Alright, let's dive into the \*\*Present Simple tense\*\*! This tense is one of the most common in English and is mainly used for talking about things that happen regularly, general truths, schedules, and even giving instructions. Let's look at how to form it, the different sentence structures, and when to use it. \#\#\# Forming the Present Simple To form the present simple tense, we mostly use the \*\*infinitive form of the verb\*\*. For example, verbs like "talk," "eat," and "go" are in their base form. Here's how it works based on the subject: \- For \*\*\"I,\" \"you,\" \"we,\" and \"they\"\*\*, just use the verb as it is: \*I talk, you eat, they go.\* \- For \*\*\"he,\" \"she,\" and \"it\"\*\*, we add an \*\*"-s"\*\* to the verb: \*he talks, she eats, it goes.\* \#\#\#\# Spelling Exceptions Sometimes, we have to adjust the spelling when adding \"-s.\" For instance, if a verb ends in \*\*-ch, -sh, -x, -s, or -z\*\*, we add \*\*"-es"\*\* instead of just \"-s\": \- \*He watches\*, \*she washes\*, \*it fixes\*. \#\#\# Sentence Structures in Present Simple We use present simple in three main types of sentences: \*\*affirmative (positive), negative, and questions\*\*. \#\#\#\# 1. Affirmative Sentences To form a positive sentence, we just use: \- \*\*Subject + Verb\*\* \- \*Examples\*: \*I talk\*, \*He eats\*, \*They learn\*. \#\#\#\# 2. Negative Sentences For negative sentences, we add \*\*"do not" (don't)\*\* or \*\*"does not" (doesn't)\*\* with the verb. Notice: \- \*I don't talk.\* \- \*He doesn't eat.\* \- \*They don't learn.\* In negative sentences, the main verb stays in its base form because the auxiliary verb "do" takes on the tense. \#\#\#\# 3. Interrogative Sentences (Questions) In questions, we start with \*\*"do" or "does"\*\*: \- \*Do you talk?\* \- \*Does he eat?\* \- \*Do they learn?\* As with negative sentences, the main verb remains in its base form, and it's the auxiliary "do" that changes based on the subject. \#\#\# When Do We Use the Present Simple? 1\. \*\*Regular Actions\*\*: We use the present simple to talk about habits, routines, or things that happen regularly. \- \*I always talk to my mother on Sunday.\* \- \*He never eats vegetables.\* \- \*They usually learn something new in class.\* \- \*\*Tip\*\*: Time words like \*always, every day, usually, often, sometimes,\* etc., often go with the present simple. \*\*Exception\*\*: With the verb "to be" (am, is, are), place the adverb \*after\* the verb: \- \*I am always happy.\* \- \*He is often late.\* 2\. \*\*General Truths or Scientific Facts\*\*: Use present simple to state things that are always true or accepted as facts. \- \*Water boils at 100°C.\* \- \*The Earth revolves around the Sun.\* \- \*Elephants live in Africa.\* 3\. \*\*Scheduled Events in the Near Future\*\*: For things like timetables or planned events. \- \*The train leaves at 10:00.\* \- \*Does the festival start tomorrow?\* \- \*The plane doesn't arrive today.\* 4\. \*\*Instructions (Imperatives)\*\*: When giving directions or commands. \- \*Open the window.\* \- \*Do your homework.\* \- \*Don't cry.\* By understanding these structures and uses, you can master the present simple and communicate with clarity about routines, facts, schedules, and instructions. Let's put this into practice and try making some sentences of your own!\" \"Alright, let's get into the \*\*Present Perfect Tense\*\*! This tense may seem tricky at first, but once you get the basics down, it becomes quite simple. We use the present perfect tense to talk about actions that happened in the past but still have some relevance or impact now. Let's break down its definition, uses, structure, and a few examples to make it crystal clear. \#\#\# What Is the Present Perfect Tense? The present perfect tense describes: 1\. An action that just happened in the recent past but still affects the present. 2\. An action that happened at an indefinite time in the past but connects to the present in some way. Think of it as a bridge between the past and the present---it links an event in the past with its ongoing effect or relevance now. \#\#\# Uses of the Present Perfect Tense The present perfect tense has a few key uses: 1\. \*\*Past Actions with Present Relevance\*\*: Use it to talk about something that happened in the past but is still important now. \- \*Example\*: \*I have already eaten breakfast.\* (The action is done, but it matters now because I'm not hungry anymore.) 2\. \*\*Actions Continuing into the Present\*\*: Use it for events that began in the past and are still happening. \- \*Example\*: \*They have lived in this city for ten years.\* (They started living here in the past, and they're still here.) 3\. \*\*Connecting Past and Present Events\*\*: This tense can link past experiences or actions to present situations. \- \*Example\*: \*She has traveled to five countries.\* (This experience affects her perspective now.) \#\#\# Structure and Formula of the Present Perfect Tense To form the present perfect tense, the structure is: \- \*\*Subject + have/has + past participle + the rest of the sentence\*\* \- \*Examples\*: \- \*I have visited Paris.\* \- \*He has completed his assignment.\* \- \*We have seen this movie before.\* Let's look at how the present perfect works with different pronouns: \| \*\*Pronoun/Noun\*\* \| \*\*Example\*\* \| \|\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--\|\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--\| \| I \| \*I have worked as a teacher for two years.\* \| \| You \| \*You have worked as a teacher for two years.\* \| \| We \| \*We have worked as teachers for two years.\* \| \| He \| \*He has worked as a teacher for two years.\* \| \| She \| \*She has worked as a teacher for two years.\* \| \| They \| \*They have worked as teachers for two years.\* \| \| It \| \*It has been here the whole time.\* \| By practicing the present perfect tense, you'll get comfortable with expressing past actions that matter now or continue into the present.

Power systems engineers play a key role in developing renewable energy sources, which is essential for a sustainable future. Now I will share the slides and give you the main information about **electrical engineering**. **What is Electrical Engineering?** Electrical engineering covers many areas, but essentially, it's the study of how to generate, transmit, and apply electricity in practical ways. Engineers in this field bring electricity into our lives---powering homes, offices, industries, and even our devices. Let's three three key elements within electrical engineering: - **Electricity**: This is the starting point. Electrical engineers figure out how to produce, transmit, and distribute electricity. Imagine the lights in your house or the fridge keeping your food fresh; these systems depend on electricity supplied by a complex infrastructure that electrical engineers help design. - **Electronics**: This area focuses on circuits and devices that power the electronics in our lives, like computers and phones. Electronics engineers are the experts who create the small but essential circuits in these devices. - **Electromagnetism**: This concept drives many electrical systems, from motors in your washing machine to generators in a power plant. Electromagnetism makes motors spin and helps transformers change voltage levels to safely deliver electricity to our homes. **Key Areas of Electrical Engineering** Electrical engineering is a broad field with many specialized areas. Let's take a look at some of the main branches where electrical engineers work: 1. **Power Engineering**: where they design and manage systems that generate and distribute electricity. When you flip a light switch, it's power engineering at work. From power plants to the wires connecting cities, power engineers make sure electricity reaches us safely and reliably. 2. **Control Engineering**: those who create systems that keep machines and devices running smoothly. Take an airplane, for instance. Control engineers design systems that automatically adjust the plane's position in the air, helping the pilot fly it safely. 3. **Electronics**: Electronics engineers design the tiny components---like transistors and capacitors---that make up the circuits in our devices. These engineers make miniaturized technology possible, enabling us to have powerful computers in our pockets, like smartphones. 4. **Telecommunications**: This area focuses on the networks that allow us to communicate. Every time you make a call or browse the internet, telecommunications engineers have designed the infrastructure that enables data to be transmitted quickly and efficiently. 1. **Signal Processing**: Signal processing is all about transforming and analyzing data, whether that's an audio signal, a visual image, or data for communication. It's used in applications like improving sound quality, image processing, and even radar systems. **Core Concepts in Electrical Engineering** To understand electrical engineering, it helps to know a few basic concepts: - **Voltage**: Voltage is like the pressure that pushes electricity through a circuit. Imagine it as the pressure in a water pipe. The higher the voltage, the more forcefully electricity flows. - **Current**: Current is the actual flow of electricity, similar to water flowing through a pipe. The stronger the current, the more electricity is moving through a conductor. - **Resistance**: Resistance limits the flow of current, like a narrow section in a water pipe that restricts water flow. Materials with high resistance, like rubber, block the flow of electricity, while materials with low resistance, like copper, let it pass through easily. - **Ohm's Law**: This essential law links voltage, current, and resistance. If you know two of these values, you can calculate the third. For example, if you increase voltage while keeping resistance steady, the current will also increase. **How Electrical Engineering Shows Up in Real Life** Electrical engineering is practical, and it's everywhere in our lives. Here are some examples: - **Power Systems**: From power plants that generate electricity to transmission lines that carry it, power engineering keeps our lights on. Every time you charge your phone or turn on the AC, it's power engineering making that possible. - **Electronics and Computing**: Every time you use a smartphone or computer, you're using technology designed by electronics engineers. They create circuits that perform millions of calculations per second, allowing us to browse the web, stream videos, and play games. - **Telecommunications**: Telecommunications engineers build the networks for our phone calls, texts, and internet. When you connect to Wi-Fi or make a video call, you're experiencing their work. - **Robotics and Automation**: In manufacturing, robots help speed up production. For instance, in car factories, robots weld and assemble parts. Control engineers create the systems that allow these robots to move with precision and efficiency. - **Renewable Energy**: As we shift toward renewable energy, electrical engineers are designing and integrating solar and wind power systems.

Plural Nouns** The first one is the plural nouns, which indicate more than one person, place, animal, or thing. They come with a few rules, but don't worry---I'll guide you through them step by step. **Rules to Form Plural Nouns** 1. **Add 's'** to most nouns: Examples: \"cat\" becomes \"cats,\" \"table\" becomes \"tables.\" - Sentence: *I saw three cats in the garden.* 2. **Add 'es'** to nouns ending in 's,' 'sh,' 'ch,' or 'x': Examples: \"bus\" → \"buses,\" \"box\" → \"boxes.\" - Sentence: *I packed the boxes for school.* 3. **Change 'y' to 'ies'** if the noun ends in a consonant + 'y': Examples: \"baby\" → \"babies,\" \"city\" → \"cities.\" - Sentence: *The hospital is full of babies today.* - But if there's a vowel before the 'y,' just add 's': - Examples: \"boy\" → \"boys,\" \"key\" → \"keys.\" - Sentence: *The boys are playing soccer in the park.* 4. **Change 'f' or 'fe' to 'ves'** for some nouns: Examples: \"knife\" → \"knives,\" \"leaf\" → \"leaves.\" - Sentence: *The trees shed their leaves in autumn.* - Note: Some nouns, like \"roof\" or \"cliff,\" just add 's.' 5. **Some nouns stay the same** in singular and plural forms: Examples: \"sheep\" → \"sheep,\" \"deer\" → \"deer.\" - Sentence: *We saw a herd of deer in the forest.* 6. **Irregular plural forms:** Examples: \"man\" → \"men,\" \"child\" → \"children,\" \"tooth\" → \"teeth.\" - Sentence: *The dentist fixed my teeth yesterday.* **2. Countable Nouns** Countable nouns are things we can count---simple as that! These nouns have both singular and plural forms. **Examples:** - Singular: *one apple, one car, one book.* - Plural: *two apples, three cars, five books.* We often use words like \"a,\" \"an,\" \"many,\" \"a few,\" or specific numbers with countable nouns. - Example sentences: *Tom brought ten packets of chips for the trip.* - *I saw an aeroplane this morning.* **3. Uncountable Nouns** Uncountable nouns, on the other hand, are things we cannot count individually, like water, sugar, or advice. These nouns don't have plural forms and are always treated as singular. **Examples:** - Substances: *water, rice, sugar.* - Abstract ideas: *love, happiness, freedom.* **How to Use Uncountable Nouns:** We often pair them with measurements or containers to specify quantity. - Example sentences: - *I drank a glass of water.* - *We need a bag of rice for cooking.* - *I have a lot of homework to finish.* **4. Collective Nouns** Collective nouns refer to groups---whether of people, animals, or things. **Examples:** - For animals: *a pride of lions, a flock of sheep.* - For people: *a team of players, a band of musicians.* - For things: *a pair of shoes, a chain of mountains.* **Sentence Examples:** - *The flock of sheep grazed in the field.* - *We hiked up the chain of mountains yesterday.* **5. Concrete Nouns** Concrete nouns are the most tangible type of noun---they are things you can see, touch, hear, taste, or smell. **Examples:** - *The book is on the table.* (You can touch and see both.) - *I had a cup of coffee this morning.* (You can taste it.) - *Hardy goes to school by bus.* **6. Abstract Nouns** Abstract nouns are the opposite of concrete nouns. They refer to ideas, qualities, or feelings---things you cannot touch or see but can only feel or think about. **Examples:** - *Love is a powerful emotion.* (You can feel love but not see it.) - *Honesty is the best policy.* (Honesty is a quality.) - *Courage is needed to face challenges.* Other examples: *freedom, anger, joy, hope.* **Why Is This Important?** Understanding these types of nouns will make your sentences clearer and more engaging. For example: - Instead of saying, *\"I have things to do,\"* you could say, *\"I have homework to complete and dishes to wash.\"* It's a simple change, but it makes your message much more precise! Now we will take another road with the **Synonyms** Synonyms are words that have the same or nearly the same meaning as another word. They are incredibly useful for improving your communication. Instead of repeating the same word, you can use a synonym to add variety or precision. Using synonyms helps you: - **Add variety** to your speech and writing. - **Convey subtle shades of meaning** to express yourself more precisely. - **Improve your overall vocabulary** for better communication. - **Adapt your language** to different situations and audiences. **Examples of Common Synonyms** - **Happy**: Joyful, elated, cheerful. - **Big**: Large, enormous, gigantic. - **Fast**: Quick, rapid, swift. - **Smart**: Intelligent, clever, bright. **Using Synonyms in Context** Let's look at an example: - Original: \"The child is **happy**.\" - With Synonyms: - \"The child is **joyful**.\" - \"The child is **elated**.\" Each synonym expresses happiness, but the intensity changes. **\"Elated\"** shows a stronger emotion than **\"joyful.\"** Choosing the right synonym allows you to create more vivid and accurate expressions. **And for** Antonyms they are words with opposite meanings. They help us express contrasts and comparisons, making our communication more dynamic and descriptive. **Types of Antonyms** 1. **Complementary Antonyms**: These are pairs of words that are mutually exclusive,one is the opposite of the other. - Example: - **Alive** ↔ **Dead**. - **True** ↔ **False**. 2. **Gradable Antonyms**: These are opposites that can be modified by degrees, with words in between. - Example: - **Hot** ↔ **Cold** (with \"warm\" and \"cool\" as middle points). 3. **Relational Antonyms**:These describe reciprocal relationships, where one word implies the existence of the other. - Example: - **Teacher** ↔ **Student**. - **Buyer** ↔ **Seller**. Antonyms are great for creating contrast or emphasizing differences. For example: **Synonyms and Antonyms in Action** Let's compare how synonyms and antonyms work by rewriting sentences: **Original Sentence** **With Synonyms** **With Antonyms** -------------------------------------- ------------------------------------------------------ ------------------------------------------------ The big dog ran quickly. The **enormous** canine sprinted **swiftly.** The **tiny** cat crawled **slowly.** She felt happy about the good news. She felt **elated** about the **excellent** tidings. She felt **dejected** about the **bad** news. The brave soldier fought in the war. The **courageous** warrior battled in the conflict. The **cowardly** civilian fled from the peace. **What Does This Show?** - **Synonyms** help us express the same idea in different ways, adding richness to our language. - **Antonyms** give us the opposite perspective, helping us compare and contrast ideas. **Part 1: What is the Present Perfect Continuous Tense?** The **Present Perfect Continuous Tense** is used to describe actions that started in the past and are still ongoing in the present. It's also called the **Present Perfect Progressive Tense** because the action progresses over time. **How Is It Formed?** To form this tense, we use the following structure:\ **Subject + have/has + been + present participle (verb+ing) + the rest of the sentence** - **"Have" or "Has"**: Use "have" with plural subjects (I, you, we, they) and "has" with singular subjects (he, she, it). - **"Been"**: This stays the same for all subjects. - **Present Participle**: The verb takes the "-ing" form. **Examples** Let's look at how the tense is used with different subjects: - **I have been studying for three hours.** *(I started three hours ago and am still studying.)* - **She has been practicing the piano since this morning.** *(She began in the morning and hasn't stopped.)* - **It has been snowing all day.** *(The snow started earlier and is still falling.)* - **We have been working on this project together for weeks.** - **I have been studying for three hours.** The material is challenging, but I\'m starting to understand it better. It\'s been a long session, but I feel like I\'m making progress. - She has been practicing the piano since this morning. She\'s trying to master a new piece for her upcoming recital. The melody is complex, but she\'s slowly getting it down. She\'s dedicated to her music and her hard work is paying off. - It has been snowing all day. The snow is piling up, creating a beautiful winter landscape. The roads are starting to get slippery, so it\'s important to drive carefully. I hope this weather continues, it\'s so peaceful. - We have been working on this project together for weeks. It\'s been a challenging project, but we\'ve learned a lot. We\'ve faced some obstacles, but we\'ve overcome them as a team. We\'re finally starting to see the light at the end of the tunnel. **When Do We Use It?** 1. **For ongoing actions that started in the past and continue now**: - *They have been living in Paris since 2020.* - *He has been working on the report for hours.* 2. **For recently completed actions with evidence or results in the present**: - *You look tired. Have you been running?* - *Her hands are dirty; she has been gardening.* **Part 2: Comparing Tenses** Finally, let's clarify how the **Present Perfect Continuous Tense** differs from other tenses. **1. Simple Present Tense** - **Definition**: Describes habits, facts, and regular activities. - **Example**: *She walks to school every day.* **2. Present Continuous Tense** - **Definition**: Describes actions happening right now or temporary situations. - **Example**: *She is walking to school right now.* **3. Present Perfect Tense** - **Definition**: Describes actions completed in the past with a connection to the present. - **Example**: *She has finished her homework.* (The result is present---her homework is done.) **4. Present Perfect Continuous Tense** - **Definition**: Describes actions that began in the past and are still continuing or have recently stopped with evidence. - **Example**: *She has been studying for two hours.* (The action started earlier and continues now.) **Tense** **Key Idea** **Example** -------------------------------- ------------------------------------ -------------------------------------- **Simple Present** Habit or fact *I read books daily.* **Present Continuous** Ongoing action *I am reading a book now.* **Present Perfect** Completed action with present link *I have read that book before.* **Present Perfect Continuous** Ongoing action since past *I have been reading for two hours.* **Conclusion** The **Present Perfect Continuous Tense** helps us express ongoing actions that connect the past to the present. Meanwhile, **word formation** through suffixes and compounding expands our vocabulary, enabling us to communicate with precision and creativity. Now that you understand these concepts, I encourage you to practice creating your own sentences using each tense and try forming new words with suffixes and compounds. Practice makes perfect! Thank you! Good morning, everyone! Thanks for taking the time to watch the video about civil engineering. I hope you've been able to get a good idea of what civil engineers do and have a summary ready about the main points from the video. Today, we're going to discuss civil engineering more deeply in a way that's open and easygoing. We'll explore what this field offers, why it's important, and what different specializations there are. \#\#\# Here are a few questions to get us started: 1\. \*\*What made you interested in civil engineering?

A willingness to learn new technologies and methods is also essential since civil engineering is constantly evolving. Let\'s pick up where we left off and take a look at the course. **Today, let\'s dive into what civil engineering is really about.** Think of it as one of the core disciplines that supports everything we see in our physical surroundings. Imagine the roads you take, the bridges that cross rivers or highways, the tall buildings in our cities, and even the water systems that ensure you have safe water at home---civil engineering is involved in every one of those projects. This field is about creating, improving, and maintaining the structures that keep our lives running. Civil engineering isn't just about building something and leaving it. It's a mix of smart planning, science, and creative problem-solving to make sure structures are safe, reliable, and sustainable over time. For instance, consider designing a road. A civil engineer must think about how much traffic the road will handle, what materials will make it last, how to prevent it from cracking due to weather, and even how it might affect traffic flow in the surrounding areas. In civil engineering, you'll need to know a lot of math and physics, but you also need to think outside the box. For example, building a dam doesn't just require knowing how to pour concrete. You have to understand the forces at play, like the pressure of the water and how it changes with the seasons. You'll even need to consider the impact on the environment and nearby communities. Smart Planning Where Engineers use science and creativity to ensure structures are safe and sustainable. They are involved in every step, from initial planning to designing and building, ensuring projects are both functional and reliable for the long term. Problem-Solving Civil engineers tackle complex challenges to create reliable infrastructure that serves the needs of society while maintaining safety and durability. Overall, civil engineering is really about finding practical solutions to make life easier, safer, and more sustainable. **Civil engineering is a huge field that covers many different jobs, all focused on making life better for people.** Civil engineers design, build, and maintain the things we use every day---like roads, bridges, buildings, water systems, and much more. They're involved in every step of making these things, from planning and designing to making sure they're safe and durable. Today, we'll go over what civil engineers do in different areas, and I'll give you examples to show how their work affects our daily lives. There are nine main types of projects, and each one has a unique role. **\*\*Let's start with Construction Engineering.\*\*** People sometimes think construction and civil engineering are separate, but construction is actually a part of civil engineering. Construction engineers are the ones who make building plans a reality. Imagine we're building a new hospital. First, construction engineers would look at the plans and make sure they're feasible to build. They assess site conditions, evaluate design specifications, and ensure the project meets regulatory standards. They check materials, costs, and timing, and then coordinate with everyone involved, from architects to workers on-site. The construction engineer's role involves \*\*planning\*\*, ensuring the designs are feasible, and reviewing all aspects of the building process. This includes analyzing site conditions, evaluating designs, and meeting regulations. Then, it moves into \*\*coordination\*\*, where construction engineers manage the various teams---architects, contractors, subcontractors, and suppliers---to ensure smooth execution. Throughout the process, construction engineers oversee the \*\*execution\*\*, ensuring the building process follows safety protocols, maintaining high-quality standards, and supervising site activities. **Let's talk about Environmental Engineering.** Environmental engineers focus on protecting the environment. They work to reduce pollution and ensure that construction projects don't harm the natural world. Imagine a company wants to build a factory. An environmental engineer would assess how the factory might affect nearby rivers or air quality. They would create plans to treat waste before it enters the river, ensuring it doesn't harm aquatic life or make the water unsafe for people. So they need to focus on **air and water quality** by developing strategies to minimize pollution. This includes implementing pollution control measures, such as dust suppression techniques and wastewater treatment systems. They work on **waste management and recycling**, designing systems to properly collect, treat, and dispose of waste generated during construction. This encompasses developing recycling programs, promoting resource conservation, and ensuring compliance with environmental regulations. In addition, environmental engineers promote **sustainable construction practices** throughout the project. They explore renewable energy sources, optimize building designs for energy efficiency, and work towards obtaining green building certifications to ensure that projects are as environmentally responsible as possible. Ultimately, environmental engineers ensure that projects are completed in a way that respects nature and helps maintain a healthy environment for future generations. **Next, we have Geospatial and Geotechnical Engineering.** These two areas of civil engineering focus on understanding the land and the ground we build on, ensuring that structures are not only placed accurately but also have solid foundations to stand on. **Geospatial engineers** are like modern-day mapmakers, using advanced tools such as GPS and Geographic Information Systems (GIS) to collect data and create detailed maps. Their work is essential in many construction projects. For example, when a city plans to build a new highway, geospatial engineers go out to the site to measure the land. They use their technology to create maps that help the construction team understand the best places to build. This work also extends to other projects, such as identifying safe locations for buildings, mapping national parks, and even planning disaster response. Without geospatial engineers, we wouldn't have the accurate maps and data necessary for effective planning. On the other hand, **geotechnical engineers** focus on what's beneath us---studying soil and rock conditions to make sure that the ground can support the structures we build. Imagine a company wants to build a dam; the geotechnical engineer would assess the soil and rock to make sure they're strong enough to hold the structure without collapsing. They also play a key role in assessing risks like landslides and earthquakes. For instance, if we wanted to build a road in a mountainous area, a geotechnical engineer would first check for landslide risks and help design the road in a way that minimizes those dangers. Their job is to ensure that all str
