June 2 In Physics History - Births – Physicists born on June 2

Eric Voice (2 Jun 1924 - 11 Sep 2004)

He was an English nuclear scientist who was one of 12 volunteers that were injected with plutonium between 1992 to 1998. He volunteered to ingest a minute amount of plutonium as a part of European research. This research was done to track plutonium in the body’s metabolism. At the age of 73, he again volunteered to inhale plutonium to help for further study. He was one of the first Western scientists to visit Chernobyl after the explosion in 1986.

Pete Conrad (2 Jun 1930 - 8 Jul 1999)

He was an American astronaut who was a crew member of the Apollo 12 mission. He was the third man to walk on the Moon during the mission. He had been selected in 1962 to join NASA as the second group of astronauts after serving as a US Navy test pilot. He was also a member of a record-breaking flight around the world in a Lear Jet. His motorcycle crashed when he was 69 and he died in the accident.

Clair Cameron Patterson (2 Jun 1922 - 5 Dec 1995)

He was a US geochemist who measured the age of the earth to be 4.55 billion years in 1953. In geochemical research, he pioneered in three major areas. 1) established the pattern of isotopic evaluation of lead on earth. This was done by analyzing critical rocks, sediments, and the waters of the planet. He created a powerful tool for identifying and evaluating the nature of the major geochemical reservoirs. 2) studied environmental lead pollution. 3) he provided the first precise age of the earth and meteorites. He studied the isotopic compositions and concentrations of lead in terrestrial materials.

Henry Joseph Round (2 Jun 1881 - 17 Aug 1966)

He was an English electronics engineer who developed and invented many devices that helped in the development of radio communications. He devised the elements of direction-finding equipment right after he joined the Marconi company in 1902. He became the chief of Marconi research in 1921. He also invented and designed the straight-eight gramophone recording system. He invented a talking picture system that was used to record sound on 2 films during the cinema of the 1930s.

Robert Morris Page (2 Jun 1903 - 15 May 1992)

He was an American physicist who was an expert in the field of circuit theory and components for early pulse radar systems. While employed at the US naval research laboratory, he invented the technology for pulse radar. This invention became vital to the allies for the detection of enemy planes and other targets during World war II. He continued research applications of radar and many other fields of electronics. He patented 65 projects for development in these fields. Today it is used in weather forecasting, astronomy, navigation, and other technical fields.

Donati Comet Observed

Giovanni Battista Donati first observed the comet and named it in 1858. It was the second brightest comet of the nineteenth century. It reached nearest to the Earth on 9 October 1858. It was the first comet to be photographed having an orbital period of about 2000 years.

The Royal Swedish Academy Founded

The Royal Swedish Academy of sciences was founded in 1739. It was inspired by the Royal Society of London and was created as an independent and non-governmental scientific society. Its main objective was to promote science. It took interest in increasing the uses of scientific discoveries in society during its early years. Its permanent secretary was the chemist, Jons Berzelius. Now, its role is in awarding the Nobel Prizes.

Edward Walter Maunder (12 Apr 1851 - 21 Mar 1928)

He was an English astronomer who first started the British Civil Services Commission examination for the post of photographic and spectroscopic assistant at the Royal Observatory, Greenwich. He worked at the observatory for the next forty years measuring the sunspots and checking historic records. He found a lack of reports on sunspots from 1645 to 1715. Instead of questioning this, he started researching and found that there are indeed decades-long times when the sun has very few sunspots. Now we call these periods as Maunder minima.

Ferdinand von Lindemann (12 Apr 1852 - 6 Mar 1939)

He was a German mathematician who proved that π is not a solution to any algebraic equation with a rational coefficient. This explained the insoluble natural or classical Greek mathematical problem of constructing a square with the same area as a given circle using a ruler and compasses alone. He discussed Hermite’s methods that he used to prove that ‘e’ is transcendental. He extended Hermite’s results in 1882 to show that π was also transcendental.

Charles Messier (26 Jun 1730 - 12 Apr 1817)

He was a French astronomer who first compiled a systematic catalog of “M objects” and discovered 15 comets. His catalog contained nebulae, 103-star clusters, and galaxies. He concluded the alphanumeric names for objects like M1, M2, etc.

Geoffrey F. Chew (5 Jun 1924 - 12 Apr 2019)

He was an American physicist who led the group of S-matrix theorists researching the strong interaction and the bootstrap principle. He was a graduate student of Enrico Fermi. His group calculated the interactions of bound-states without assuming that there is a point-particle field theory underneath.

Igor Tamm (8 Jul 1895 - 12 Apr 1971)

He was a Soviet physicist who shared the Noble Prize with Pavel A  Cherenkov, and Ilya M. Frank for physics for his works in explaining Cherenkov radiation. He developed the theoretical interpretation of the Cherenkov effect which states that the radiation of electrons moves faster than the speed of light through matter. He also developed a method for studying the interaction of nuclear particles and contributed towards the methods for the control of thermonuclear reactions.

First Man To Orbit The Earth

On this day, Yuri Gagarin became the first man to orbit the Earth in 1961. The control of the spacecraft was locked to prevent him from taking control of the ship. It had a radio, television, and life-supporting equipment. He ejected and made a planned descent landing with his parachute but the Soviet Union denied this to save its reputation. After 7 years, he died in a plane crash.

The First Yo-Yo Toy In Space

The first yo-yo toy was taken into space in the Space Shuttle Discovery mission 51-D in 1985. With this yellow plastic Duncan Imperial yo-yo, other toys were exhibited during a time in orbit. Astronauts did the tricks with toys but the yo-yo sleeper trick couldn’t work without normal gravity. While spinning, the gyroscope showed exceptional stability. The flywheel slowed without normal gravity.

Space Shuttle Columbia Was Launched

Columbia, the American Space Shuttle was launched into space in 1981. John W. Young was the mission commander.
