January 2 in Physics History - Births – Physicists born on January 2

Rudolf Clausius (2 Jan 1822 - 24 Aug 1888)

He was one of the founders of thermodynamics. He contributed to it by giving the second law of thermodynamics. He wrote the right important papers on this topic. He restated Sadi Carnot’s principle of heat engines. He also researched in molecular physics and electricity. The Clausius-Clapeyron equation expresses the relation between the pressure and temperature at which two phases of a substance are in equilibrium.

Donald B. Keck (Born - 2 Jan 1941)

He was an American research physicist. With his colleagues, he invented fused silica optical waveguide- optical fiber. This invention created a revolution in telecommunications, capable of carrying 65,000 times more information than conventional copper wire. He, along with his colleague, produced the first optical fiber with optical losses low enough for wide use in telecommunications.

Johann Daniel Titius (2 Jan 1729 - 16 Dec 1796)

He was a Prussian astronomer, physicist, and biologist. He suggested that the mean distances of the planets from the sun are given by A= 4+(3x2n) giving the series 4, 7, 10, 16, 28*, 52, 100, corresponding to the relative distance of the six known planets up to Saturn.

Sir George Biddell Airy (27 Jul 1801 - 2 Jan 1892)

He became the seventh Astronomer Royal. He was the one who computed the density of Earth by swinging a pendulum at the top and bottom of a deep mine, determined the mass of Jupiter, calculated the orbits of comets. He also designed corrective lenses for astigmatism. He too suffered from astigmatism.

The First Photograph of the Moon

The French photographer Louis Daguerre took the first photograph of the moon. But, on 8 May 1839, a fire burned his laboratory into ashes. The first-ever photograph of the Moon, along with his records and his early experiments were lost. After then John Adams Whipple took the earliest photo of Moon in 1851.

Luna 1

On this day, the Soviet Union launched the first lunar space shot to escape the Earth’s gravitational pull. This unmanned mission was named as Luna 1. It was intended originally to impact the Moon, but due to the guidance system error, it became the first spacecraft to enter Sun’s orbit instead.
