The Information Age Bryan Lloyd P. Bretaña Faculty Department of Biological Sciences College of Arts and Sciences Kabacan, Cotabato  Learning outcomes To determine the human and social impacts of the developments in the information age. To discuss the evolution of technology from the ancient times up to the present. To illustrate how social media have affected our lives. Science, Technology and Society_BLPBretana2018  The Information Age (Digital Age) When was the last time you used something digital? Science, Technology and Society_BLPBretana2018  The Information Age (Digital Age) Also called the New Media Age A period starting in the last quarter of the 20th century when information became effortlessly accessible through publications and through the management of information by computers and computer networks Science, Technology and Society_BLPBretana2018  The Information Age (Digital Age) The focus of S&T and society became “information” itself (handling and conveying it) Progress in electronics and computers caused information to be one of the most important commodities Science, Technology and Society_BLPBretana2018  The Information Age (Digital Age) Advances in biology Genetics –revolution in information science (recombinant DNA) The immune system –also an information processing system Science, Technology and Society_BLPBretana2018  Information & Society Science, Technology and Society_BLPBretana2018  Information Literacy The ability to: Access needed information Evaluate information found Organize information Use information from a variety of sources Science, Technology and Society_BLPBretana2018  Computer Literacy The ability to use the computer hardware and software necessary to accomplish routine tasks Science, Technology and Society_BLPBretana2018  Information Literacy vs Computer Literacy Information literacy Computer literacy A client who is information A client who is computer literate knows how to find literate has the technical skills the information needed and and knowledge of computers can evaluate the information necessary to use founded for accuracy, contemporary hardware and currency and bias. software and can adapt to new technologies that emerge. Science, Technology and Society_BLPBretana2018  Information & globalization Communication worldwide became cheap (with new phone systems and Internet) Changed the way people work Information-based work Business trends Global banking Scientific enterprise/research Science, Technology and Society_BLPBretana2018  Problems with Information age Infringement of personal privacy Excessive use of computers in teaching young children may impoverish the development of intellectual capabilities “Knowledge” is replaced by mere “data” Ideas contain data, but data contain no ideas Science, Technology and Society_BLPBretana2018  Facts on the Information age ✓ Information must compete. ✓ Newer is equated with truer. ✓ Selection is a viewpoint. ✓ The media sells what the culture buys. ✓ The early word gets the perm. ✓ You are what you eat and so is your brain. ✓ Anything in great demand will be counterfeited. ✓ Ideas are seen as controversial. ✓ Undead information walks ever on. ✓ Media presence creates the story. ✓ The medium selects the message. ✓ The whole truth is a pursuit. Science, Technology and Society_BLPBretana2018  Reflection… Social media poses certain risks especially in the dissemination of false information. As a student, how will you use social media to ensure that you do not propagate inaccurate and unreliable information? Science, Technology and Society_BLPBretana2018  What brought us here? Science, Technology and Society_BLPBretana2018  Printing press- Johannes Gutenberg a device that applies pressure to an inked surface lying on a medium i.e. cloth or paper to transfer the ink a device that applies pressure to an inked surface lying on a medium i.e. cloth or paper to transfer the Gutenberg’s printing press ink youtu.be/0ojyCDRc8uc Science, Technology and Society_BLPBretana2018  Computers were people who compiled actuarial tables and did engineering calculations. During World War II, the Allies, countries that opposed the Axis powers (Germany, Japan and Italy): had shortage of human computers for military calculations United States mechanized the problem by building the Harvard Mark 1 an electromechanical monster 50 feet long capable of doing calculations in seconds Enigma machine British needed mathematicians to crack the www.ilord.com German Navy’s Enigma code used by Germans to transcribe their messages in encryption using a machine called Enigma looked like an oversized typewriter Science, Technology and Society_BLPBretana2018  A generation with “electronic brains” was born by the 1970s who wanted their own personal computers (PCs). In 1975, members of the Homebrew Computer Club, became eager with the potential of the new silicon chips allow them build their own computers Steve Wozniak built a simple computer around the 8080 microprocessor hooked up to a keyboard and television in 1976 Steve Jobs called the computer Apple I and sold replicates of this machine to a Silicon Valley shop Bill Gates realized that PCs needed software and sold his Microsoft programs Science, Technology and Society_BLPBretana2018  From 1973 onwards different social media creations were introduced: multi-user chat rooms instant-messaging e.g. AOL, Yahoo messenger, MSN messenger, Windows messenger conferencing and bulletin-board forum system exchanging e-mails game-based social networking websites i.e. Friendster, Myspace, Facebook, Twitter, VK, Tumblr business-oriented social networking websites i.e. Xing messaging, video and voice calling service e.g. Skype Science, Technology and Society_BLPBretana2018  blogging platform, image and video hosting website e.g. Flicker discovery and dating-oriented website e.g. Tagged, Tinder video sharing service allowing users to post virtually everything e.g. YouTube real-time social media feed aggregator e.g. FriendFeed live-streaming e.g. Justin.tv, Twitch.tv photo-video sharing website e.g. Pinterest, Instagram, Snapchat, Keek, Vine question-and-answer platform e.g. Quora To date, these social-media platforms were just bought by one company owner to another and were modified based on the dynamic needs of the users Science, Technology and Society_BLPBretana2018  Group Activity: Hacking Background: A substitution cypher is a method of encrypting a message in which the letters of a plaintext are replaced with different ones in systematic manner. In a simple substitution, the codes may simply be a rotated or shifted alphabet. Science, Technology and Society_BLPBretana2018  Group Activity: Hacking Instruction: Each group should make its own code message composed of no more than 50 words by using simple substitution. Afterwards, exchange messages with the other groups. The first group that decodes the message wins. Start 1 1 1 1 1 1 9 8 7 6 5 4 3 2 1 5 4 3 2 1 0 Science, Technology and Society_BLPBretana2018
