Harold Stephen Black (14 Apr 1898 -11 Dec 1983)

American electrical engineer who gave the negative feedback principle in amplifiers. This principle was based on the amplification which was fed back into the output that produced nearly distortionless and steady amplification. He joined the forerunner of bell labs in 1921 and worked on the elimination of distortion. Accept mainly involved feeding systems output back to the input. Nowadays this principle has found widespread applications in electronics.

Christiaan Huygens (14 Apr 1629 - 8 Jul 1695)

He was a Dutch physicist and astronomer who discovered the true shape of the rings of Saturn and founded the wave theory of light. He discovered the first moon of Saturn platinum Titan on 25 March 1655. Discovery used a lens ground for himself. The first pendulum clock was patented by him in 1656. He also studied and made the first map of Mars and on 14 January 2005 NASA launch the space probe that was named after Huygens that landed on Titan.

Henri Giffard (8 Feb 1825 - 14 Apr 1882)

He was a French engineer who built the first airship and he traveled in it from Paris to Trappes at the speed of 8kmph. His idea of injector for feeding water into the boiler of steam locomotive earned him the Academie des sciences prize for mechanics. The balloon was cigar-shaped with a one-cylinder steam engine and it was lightweight. Later years, he constructed large tethered hydrogen balloons out of which, one balloon carried 52 passengers at the Paris Exposition 1878. Sadly he died by suicide after becoming blind and he left much money in his well for humanitarian and scientific purposes.

Atom Split By A Proton Beam

A proton beam split the atom in 1932 on a lithium target. It was carried out in the first nuclear particle accelerator which was developed by Sir John Douglas Cockcroft and Irishman Ernest Walton. The event shared the Nobel Prize for this discovery in 1951. Walton was the one who first split the atom.

Telescope Term

Prince Frederick Ko Kaisi used the word telescope in public at a banquet held by the pioneer scientific society in 1611. This event was held to honor Galileo Galilei after he showed the guests the satellite of Jupiter, other celestial marbles, and an inscription on a building 3 miles away. It is said that even though the name was announced by Casi to Christian Galileo’s instrument, the word telescope originated in Greek.
