5 INVENTORS YOU DIDN'T KNOW WHO CREATED THINGS WE USE TODAY

A.      THOMAS NEWCOMEN FIRST PRACTICAL STEAM ENGINE-

Thomas Newcomen was an engineer and inventor who built the first steam engine from James Watt’s original engine design. Newcomen started out as an ironmonger in Dartmouth and was concerned about the cost of using horses to pump out of tin mines.

For more than a decade , he had his assistant, John Calley, experimented with steam pump. design could not solve the problem of pumping water without breaking down. Newcomen’s pump worked when the pressure caused the piston to be pushed down.

B.      GOTTFRIED WILHELM LEIBNIZ CALCULUS-

Gottfried Wilhelm Leibniz was often credited with inventing differential and integral calculus. However, other mathematicians, such as Isaac Newton, have also taken credit for the development of calculus.

In Leibniz’s case, he funded his studies by building a calculating machine. He showed this device to the Royal Society during his journey to London in 1673. By 1675, he had established the principles of differential and integral calculus.

In modern times, calculus has made it possible to track the position of an object such as a space shuttle. Also, it can help to predict if a dam might burst if there is too much pressure from the water rising too high.

C.      TERVOR BAYLIS WIND-UP RADIO-

Tervor Baylis was an English inventor. He started developing a prototype for the wind-up radio after watching a TV program in 1991 about the spread of AIDS in Africa. He thought, ‘’if there are wind-up record players, then why can’t there be wind-up radios?’’ He used a clockwork motor, which was run on a coiled-up spring. The clockwork motor got his name as coiled-up springs were used in clocks.

His prototype ran for 14 minutes. After that success, he was invited on the TV program Tomorrow’s World in 1994. Then, in 1995, BayGen Power industries was established in cape town, South Africa. They employed disabled workers to build wind-up radios.

D.      GUGLIELMO MARCONI RADIO-

Guglielmo Marconi was an Italian inventor who followed in the footstep of Heinrich Hertz and James Clerk Maxwell after learning about their experiments. Marconi started his tests in 1894 on his father’s estate near Bologna. In 1895, he managed to send ratio signals from up to 1.6 kilometers away.

He used simple equipment, including an induction coil, a morse key, and a coherer to detect radio waves. But his experiments didn’t spark much encouragement from the Italian government. So he decided to go to England in 1896.

E.       JOHN LOGIE BAIRD TELEVISION-

John logie Baird started out as an engineer. But his job made him so miserable that he became an inventor instead. His first ideas failed and made him penniless at age 35. Then, in 1923, he began to work on a machine that could transmit images. It would also be able to broadcast sound via radio. He tested it by sending some crude images by wireless transmitter to a receiver a few feet away from him.

Baird television outlined images in 1924 and showed human faces you could recognize in 1925. He then gave a public demonstration of televised moving objects at the Royal Institution in London in 1926.

So that’s all about today, next topic is going to be really interesting one.
