GREATEST INVENTIONS THAT CHANGED THE WORLD
THE INVENTIONS THAT SHAPED OUR LIVES.
AIRPLANE
The inventors of the airplane were two brothers, Wilbur & Orville Wright, who were printers and bicycle builders from Ohio. Having taught themselves engineering, they began to experiment with home-built flying machines. By 1900 they had produced a glider and by 1903 a powered aircraft.

ELECTRICITY
Early
humankind used wood and peat fires to generate light and warmth. As
civilization progressed oil lamps, gas lights and candles were for lighting and
coal-burning stoves warmed houses. However, as early as 600 BCE in ancient
Greece, Thales of Miletus had discovered that rubbing amber against a fur cloth
would attract particles of straw.
X-RAYS
X-rays
are electromagnetic waves of short wavelength, capable of penetrating a
thickness of matter. They were discovered quite by accident in 1895 by Wilhem
Conrad Rontgen, a professor of physics in Germany.
SATELLITE
A
satellite is a body that orbits another, larger body in space-the moon is a
satellite of the earth, and the planets in our solar system are satellites of
the sun.
TELEVISION
John
Logie Baird is regarded as the inventor of television in the late 1920s in England,
although many other people contributed to its development, both before and
after Baird.In 1926 Baird successfully transmitted the first television picture
with his mechanical system.
BRAILLE
Braille
is a system of “printing” text, using symbols consisting of raised or embossed dots,
designed to enable blind and partially sighted people to read and write.
Braille text represents letter of the alphabet and punctuation marks; the
reader feels the dots, usually with the index fingers of both hands.
CLOCK
Devices
to tell the time of day, and to predict the seasons, have been in use for
thousands of years. The first type of clock to be designed was a sundial,
probably in about in about 3500 BCE, with a pointer casting a shadow across a
dial, marked with the hours of the day.
PAPER
CLIP
A
paper clips an ingenious but the simple device, consisting of a thin wire wound
into a flat loop, designed to hold several pieces of paper together without
puncturing them.
REFRIGERATOR
Since
prehistoric times, people have preserved food by keeping it cool, and the very
first “refrigerators” were caves packed with ice or snow. Later on, the Greeks
and Romans placed large amounts of snow into storage pits dug into the grounds,
and insulated them with wood and straw.
TELEPHONE
Controversy
surrounds the invention of the telephone. Alexander Graham Bell is usually
credited as its creator, but it was actually Antonio Meucci an Italian immigrant,
who first developed the design of the “talking telegraph” in 1849.
WHEEL
The
invention of the wheel is not just about transportation: its emergence was
essential for the development of modern technology. Without it there would have
been no spinning wheel, no watch gears or pulleys, no computer discs or
computer mice.
