Study Notes

Inventions and Discoveries

The wheel was invented around 2400 BC.
The Great Pyramid of Khufu was constructed in Egypt between 2560-2540 BC, utilizing approximately 2.3 million limestone blocks.
Blocks used in the pyramid measured approximately 2.3 m on one side and had a total weight of 58 million kg.
The pyramid stood at 146.5 m tall and took 20 years to build, employing a workforce that exceeded 100,000.
The first electric light was invented in 1809 by an English chemist.
Michael Faraday created the first electric motor.
Thomas Alva Edison was the first to produce an incandescent light bulb.
Alexander Graham Bell invented the first telephone.
The Wright brothers, Wilbur and Orville, developed the first airplane, with Orville making the first powered flight in 1908.

Historical Insights

Engineering as a formal discipline started in the 1800s through apprenticeship.
The Industrial Revolution, occurring between the 18th and 19th centuries, significantly impacted technology and society.
The second Industrial Revolution introduced advanced machines, including the milling machine and various methods in glass-making.
Major technological eras include the Pre-scientific Revolution, Industrial Revolution, Second Industrial Revolution, and Information Revolution.

Role and Definition of Engineers

Derived from the Latin ‘ingenium’, the term "engineer" implies cleverness and innovation.
An engineer applies scientific knowledge and math to develop useful products or processes, with a minimum qualification typically being a Bachelor’s degree.
Key traits of engineers include analytical skills, problem-solving ability, attention to detail, and a commitment to ongoing learning.

Ethics and Safety in Engineering

Ethics in engineering involves behavior patterns, attitudes, and reasoning, categorized into meta-ethics and normative ethics.
Whistleblowing serves to protect public interest by reporting threats or unsafe actions.
Safety aims to eliminate hazards, with risk defined as a measure of potential adverse effects to life or environment.

Communication and Documentation

Effective communication, from the Latin 'communicare', involves sharing and imparting information.
A technical report typically includes a title, nomenclature, introduction, methods, results, conclusions, references, and appendices.
Pictographic drawings offer three-dimensional representations that are easy to interpret, while charts visually represent qualitative or quantitative information.

Environmental Considerations

The biosphere encompasses life on Earth, including the atmosphere, hydrosphere, and lithosphere, covering 71% of the planet's surface.
Greenhouse gases contribute to atmospheric warming, with ozone formation associated with reactive organic gases and nitrogen oxides in sunlight.

Indigenous Technology and Intellectual Property

Indigenous technology refers to techniques developed using local resources and skills.
Protected technology involves unauthorized access to technology, while intellectual properties can be safeguarded through patents, trademarks, and copyrights.
