Analyze the development and impact of the computer and (IT) Revolution. Explain how advances in medicine and biotechnology have changed life today. Objectives

TEKS 8C: Calculate percent composition and empirical and molecular formulas. Terms and People Artificial Satellite (Sputnik) – a man-made object that orbits a larger body International Space Station (ISS) – an artificial structure built and maintained by a coalition of nations with the purpose of research Personal Computer (PC) – a small computer meant to be used by individuals or businesses Internet – a huge international computer network linking millions of users around the world

TEKS 8C: Calculate percent composition and empirical and molecular formulas. Biotechnology – the application of biological research to industry, engineering, and technology Laser – a high-energy light beam Genetics – the study of genes and heredity Genetic Engineering – the manipulation of genetic material to produce specific results Terms and People (continued)

TEKS 8C: Calculate percent composition and empirical and molecular formulas. Scientific research and technological development have transformed human history. New inventions, including the personal computer, and advances in medicine have changed both the world and people’s lives. How have advances in science and technology shaped the modern world?

TEKS 8C: Calculate percent composition and empirical and molecular formulas. In 1957, the Soviets launched Sputnik, the first artificial satellite. 1,100 active satellites today impact ever aspect of our lives (+2,600 non-working ) The U.S. Apollo program landed a man on the moon in NASA Spin-off technologies… everything from UV protected sunglasses and Velcro to cordless EVERYTHING (batteries) and your camera phone; thank NASA, next “selfie”. Since the Cold War ended, the United States and Russia have cooperated in space, advances cont. The space Race began during the Cold War as the United States and Soviet Union competed with each other to explore outer space.

TEKS 8C: Calculate percent composition and empirical and molecular formulas. Scientists and engineers have launched rockets to other planets and landed robotic vehicles on them. More than a dozen countries built the International Space Station for exploration and scientific research. Space science continued to develop after Apollo. The International Space Station in 2011

TEKS 8C: Calculate percent composition and empirical and molecular formulas. Communication: television, telephones, high-speed data transmission Observation: data for scientists, weather forecasters, etc. Navigation: GPS beam precise locations to ships and others Spy/military: Many new technologies won’t be known for years. Ten nations have launched a total of 3,700 since Satellites have been launched to orbit the Earth, for these specific purposes…

TEKS 8C: Calculate percent composition and empirical and molecular formulas. The invention of the computer during WWII created an information revolution. “Computers”, originally crunched #’s for trajectories' of artillery shells, hence, computing = math equations. They help scientists and universities to do faster and faster computations resulting in ever increasing data. The creation of the Internet, (during Cold War) made e-commerce possible, which led to the (IT) Revolution. Everything has changes in the last 25 years! 1990, first search engine “Archie”. Google a research project by two students at Stanford University, went live in Social-media…Timeline. 2004, Gmail, MySpace and Facebook. 2005, YouTube. 2006, Twitter. 2007, the iPhone the App Store on iTunes. Then lots more

TEKS 8C: Calculate percent composition and empirical and molecular formulas. After the invention of the silicon chip, it was possible for manufacturers to “get smaller” and mobile making personal computers (PCs) possible, 1981…no internet or Smarts, Yet! Mainframe computers became available in the 1960s and 70s. Desktops replaced typewriters and account books in the 80s. No Wi-Fi, Yet! Carnegie Mellon University built the first campus wide Wi-Fi, 1993, originally called “Andrew” Over time, scientists, teachers, engineers, and urban planners and average people have redefined the “Computer” through the use of Wi-fi, smartphones, tables and laptops. The first computers.

TEKS 8C: Calculate percent composition and empirical and molecular formulas. Developments in medicine and biotechnology have given people new tools to combat and prevent disease. The development of vaccines in the postwar era prevented many diseases such as polio. Medicine was also transformed by surgical advances such as organ transplants and the use of lasers and MRI’s. Computers and technology are fully integrated into the modern medical/health system Computer images of the brain and other organs allow doctors to diagnose many diseases.

TEKS 8C: Calculate percent composition and empirical and molecular formulas. These breakthroughs have brought benefits and debate over the ethics of modified foods and the role of science in creating life. Research in genetics and genetic engineering has produced new drugs and new strains of fruits and vegetables. It has also made cloning possible. Genetic researchers Watson and Crick in 1958 revealed the “double helix” structure of DNA.

TEKS 8C: Calculate percent composition and empirical and molecular formulas. Overall, science and technology have improved the standard of living for many people. Life expectancies have risen worldwide as a result of increased agricultural production and breakthroughs in treating disease. Though significant challenges remain, people will continue to work toward solving global problems in the decades to come.
