# Science, Technology & Society in the 20th Century ## Computer Presentation **Earl Randolph Salirungan** ### Exploring the World / Computers - Mobile Computers - Desktop Computers ## The First Programmable ## Magnetic Resonance Imaging - MRI is a non-invasive imaging technique using magnetic fields and radio waves to visualize internal body structures, especially soft tissues - Developed in the 1970s, with key contributions by Paul Lauterbur and Peter Mansfield - Used widely for diagnosing conditions affecting the brain, spine, and joints - Safe alternative to radiation-based imaging methods ## Computer Components / Percentage ## The Internet - The internet is the result of work by numerous pioneers, including Vinton Cerf, Bob Kahn, and Tim Berners-Lee - Evolved from early network projects like ARPANET to become a global communication network - Critical for modern information access, communication, commerce, and social interaction ## Networking / Internet ## Optical Fiber - Optical fiber technology, pioneered by Alexander Graham Bell, Narinder Singh Kapany, and Jun-ichi Nishizawa, enables fast data transmission using light signals - Essential for high-speed internet and telecommunications, allowing efficient long-distance communication ## Future Technological / Trends ## Air Conditioning System - Early cooling systems included aqueducts in ancient Rome and fans in ancient China - Willis Carrier invented the first modern air conditioning system in 1902, initially to control humidity - Now widely used for indoor temperature control, improving comfort in various environments ## Thank You For / Watching ## Gene Therapy - Gene therapy treats genetic diseases by correcting defective genes, offering potential cures for previously untreatable conditions - First trial conducted in 1990; first approved therapy in the EU in 2012 - Holds promise for treating genetic disorders like cystic fibrosis and hemophilia ## Thank You For / Watching ## 3D Metal Printing - 3D metal printing, also known as additive manufacturing, uses lasers or electron beams to create complex metal structures, reducing the need for extensive machinery or molds - Beneficial for industries requiring intricate designs, like aerospace and medical device manufacturing ## Thank You For / Watching ## Artificial Embryos - Artificial embryos, developed from stem cells, allow researchers to study early development stages, bypassing the need for sperm or eggs - This advancement raises ethical questions about genetic research, the beginning of life, and potential applications for reproductive technologies - It provides insights into cell differentiation and organ formation, which could impact regenerative medicine and infertility treatments ## Thank You For / Watching ## Cell-Free Fetal DNA Testing - Developed in the early 2000s, cell-free fetal DNA testing allows for the detection of genetic abnormalities by analyzing fetal DNA from the mother's blood - Reduces the risk of miscarriage compared to invasive tests like amniocentesis, offering a safer option for prenatal screening ## Computer / Conclusion ## Thank you The presentation is about Science, Technology, and Society in the 20th Century, focusing on the impact of computers on society. It highlights key technologies such as Magnetic Resonance Imaging, the Internet, Optical Fiber, Air Conditioning, Gene Therapy, 3D Metal Printing, Artificial Embryos, and Cell-Free Fetal DNA Testing. The presentation uses a visually appealing format with images and illustrations to convey the information.
