The Stories Of Inventions...
Inventions
Inventions are
new ideas that solve problems or prove useful to us. Thousands of years of
brilliant brainpower have resulted in things and ideas that have transformed
people’s lives. Even in the modern world, people keep coming up with new ideas
and inventions.
*Thomas Edison
(1847–1931) was an American master of invention, patenting 1,093 ideas in his
lifetime, including batteries and light bulbs.
Hand
axe- The hand axe
was the first stone tool in prehistoric times. People dug for flint, which they
shaped into handcrafted axes to cut meat, chop wood, scrape skins, and protect
themselves. Hand axes were used for more than a million years.
Wheel-
Steam
engine- The first steam
engines were used to pump water out of mines. Later, engines were used to power
factories and trains. George Stephenson’s Rocket train was built in 1829.
Flight- In 1903,
American brothers Wilbur and Orville Wright built a glider with a light engine.
Although Flyer took off for only 12 seconds over 120 ft (37 m), it was the
first-ever powered flight.
Plastics- Plastics are
cheap to make, easy to shape, and last a long time. They can be hard, soft, or
bendy. The first human-made plastic was made by Belgium-born chemist Leo
Baekeland in 1905. Now plastics are all around us.
Antibiotics- Infection-fighting antibiotics battle bacteria inside the body. They were discovered by accident in 1928, when Scottish scientist Alexander Fleming noticed bacteria dying around mold in his lab. The bacteria-killing chemical penicillin has since saved many lives.
Computers- Computers are
electric machines that follow instructions. Modern computers can do billions of
sums every second. We use them to find, store, and share information. The idea
of a computer was invented by English engineer Charles Babbage in the 1830s.(Picture7)
*The
first electronic computer, ENIAC, was huge, filling a room measuring 50 ft (15 m) long.
