January 8 in Physics History - Births – Physicists born on January 8

Stephen Hawking (8 Jan 1942 - 14 Mar 2018)

He was an English theoretical physicist who was one of the greatest leaders in his field. His areas of research were theoretical cosmology and quantum gravity. He was a Lucasian Professor of Mathematics at Cambridge University. He was confined to a wheelchair and was unable to speak due to Lou Gehrig’s disease. Despite his challenges, he utilized his intelligence, abilities, and knowledge to make remarkable contributions to the field of cosmology. He was the author of the book A Brief History of Time.

Frank Dyson (8 Jan 1868 - 25 May 1939)

He was a British astronomer who spent his almost entire career at the Royal Greenwich Observatory as an Astronomer Royal from 1910-33. He initiated the radio broadcast of time and directed measurements of terrestrial magnetism, latitude, and time. He photographed the entire sky and examined the proper motions of northern stars. He directed the 1919 eclipse expedition which confirmed the bending of starlight by the gravitational field of the Sun.

Walther Bothe (8 Jan 1868 - 8 Feb 1957)

He was a German physicist who developed the coincidence method. This method is used to detect the emission of electrons by x-rays in which electrons pass through two adjacent Geiger tubes at almost the same time. This is called a coincidental event. He used this to prove the law of conservation of energy and momentum at the atomic level. He also studied cosmic rays using this method and concluded that cosmic rays consist of massive particles. Germany’s first cyclotron was developed by him. He also shared the Nobel prize for physics in 1954.

Johannes Fabricius (8 Jan 1587 - 19 March 1616)

He was a Dutch astronomer who observed the sunspots for the first time. He saw several dark spots on the Sun when he directed his telescope at the rising Sun. He investigated this with his father and was the first to publish this information. He died when he was 29 years old.

Galileo Galilei (15 Feb 1564 - 8 Jan 1642)

He was an Italian philosopher who made significant discoveries in physics and astronomy. He perfected the telescope and also studied the science of motion, inertia, and many more. His progress came at a price when his ideas conflicted with religious dogma.

Aleksandr Mikhailovich Prokhorov (11 Jul 1916 - 8 Jan 2002)​

He was a Soviet physicist who shared the Nobel prize for physics in 1964. He worked in the field of quantum electronics that led to the development of oscillators and amplifiers based on the maser-laser principle. When the stimulated emission is larger than the absorption, amplification occurs. Prokhorov researched the master independently and also with the other scientists.

Antonia Maury (21 Mar 1866 - 8 Jan 1952)​

She was an American astronomer and ornithologist who was able to classify the stars by their spectra. She worked on 681 bright stars of the northern skies. Her achievement was published in the Annals of Harvard College Observatory. Her work was important in verifying the difference between dwarf stars and giant stars. She was the first to measure the period (104 days) of the binary star, Mizar.

John William Mauchly (30 Aug 1907 - 8 Jan 1980)

He was an American engineer and physicist who invented the first general-purpose electronic computer. In 1946, he developed the Electronic Numerical Integrator and Computer (ENIAC) with John P. Eckert. It was developed for the US Army Ordnance Department. It was a huge machine that consumed 100 kW of power.

The Discovery of Superfluidity

On this day, the superfluidity of liquid helium was discovered in 1938. When liquid helium is brought near absolute zero, it becomes a superfluid. It was reported in the journal Nature. The discovery has been made independently by P.L Kapitza as well as Jack Allen in Cambridge, England. Kapitza shared the noble prize in physics in 1978 for his discoveries in the area of low-temperature physics.
