Everyday Technology.Scientists and engineers produced more technological advances in the last hundred years than in all of recorded history Recorded history can be defined as history that has been written down or recorded by the use of language, whereas history is a more general term referring simply to information about the past.[1] It starts in the 4th millennium BC, with the invention of writing. before 1900. Airplanes In 1903 Orville Wright became the first human to fly. The plane he and his brother Wilbur built traveled only 120 feet. What made it fly: An impressive list of Wright Brothers' innovations include the first long narrow wings, flight stabilizers, and lightweight engines. Cool flight science: In 1967 the experimental X-15 rocket-plane flew at least five times the speed of sound. Rubber The U.S. Rubber Company invented Keds--the world's first rubber-soled shoes---in 1917. What made them jump: Synthetic rubber synthetic rubber: see rubber. , a stretchy stretch·y adj. stretch·i·er, stretch·i·est 1. Capable of being stretched: a stretchy fabric. 2. Tending to stretch excessively. Adj. 1. plastic, was created by German scientists for use as aircraft tires during World War 1. Cool shoe science: New Converse sneakers sneakers Noun, pl US, Canad, Austral & NZ canvas shoes with rubber soles sneakers npl (US) → zapatos mpl de lona; zapatillas fpl feature helium-filled soles, so you can jump sky high. Automobiles The Model T Ford, America's first mass-produced car, revolutionized how Americans lived in the 20th century. What made them run: Henry Ford's cost-saving assembly line and improved gas engines made the Model T a hot ticket. Cool car science: Honda's latest model runs on gas and electricity, and gets 70 miles per gallon Noun 1. miles per gallon - the distance traveled in a vehicle powered by one gallon of gasoline or diesel fuel unit, unit of measurement - any division of quantity accepted as a standard of measurement or exchange; "the dollar is the United States unit of . Computers ENIAC ENIAC in full Electronic Numerical Integrator and Computer Early electronic digital computer built in the U.S. in 1945 by J. Presper Eckert and John W. Mauchly. , the world's first electronic computer, appeared in 1945. What made the compute: Thirty, tons of equipment, including 18,000 vacuum tubes This is a list of vacuum tubes: American designation (with European equivalents)
Cool PC science: Today's computers are thousands of times faster than ENIAC and weigh just a few pounds. Plus ... Plastic American companies churn out 20 million tons of plastic each year for thousands of everyday products. Television TVs first lit up American homes in 1946. By 1998, 97% of Americans owned at least one set. Thanks goes to Philo Farnsworth, who invented the first picture tube in 1927 at the age of 21. Velcro Engineer George DeMarshal invented Velcro in 1948, inspired by burrs clinging to his pants, Today, space-walking astronauts use 173 Velcro strips to hold tools to their space suits. Bar Codes Lasers, computers, and microchips spurred the use of bar codes in 1974. Today shopping is a breeze. |
