June 5 in Physics History - Births – Physicists born on June 5

Dennis Gabor (5 Jun 1900 - 8 Feb 1979)

He was a Hungarian-British physicist who invented holography. It is a system of lenses with three-dimensional photography that has many applications. For this invention, he was awarded the Nobel Prize for Physics in 1971. The invention of holography was not possible until the invention of the laser in 1960 because the conventional filtered light sources had limitations of either too little light or too diffuse. His area of research was also on a high-speed oscilloscope, television, physical optics, and communication theory. He held more than a hundred patents.

John Couch Adams (5 Jun 1819 - 21 Jan 1892)

He was an English astronomer and mathematician who discovered the planet Neptune. Although Neptune was discovered by two people independently. He was one of them. He predicted the existence of Neptune in his journal when he saw the irregularities in the motion of Uranus. He had many more contributions to astronomy such as he studied the Leonid Meteor shower where he showed its orbit was very similar to that of a comet. So he concluded that the Leonid Meteor shower was associated with the comet. He also studied the motion of the moon and terrestrial magnetism.

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.

Roger Cotes (10 Jul 1682 - 5 Jun 1716)

He was an English mathematician who worked with Isaac Newton by proofreading the second edition of his famous book, The Principia, before publication. He obtained the logarithmic version of Euler’s formula and invented the quadrature formulas known as Newton’s cotes formula.

Augustus Edward Hough Love (17 Apr 1863 - 5 Jun 1940)

He was the British geophysicist and mathematician whose prediction was confirmed that the occurrence of a seismic wave confined to the surface layer of the Earth that traveled between the crust and the mantle. This earthquake wave was later subsequently named for him. He also studied elasticity and wrote a paper on the Mathematical Theory of Elasticity.

The First World environment day

The first World environment day was celebrated worldwide with several activities in 1974. Thereafter, June 5 has been celebrated as World Environment Day. This day was chosen because of the opening day of the conference on the human environment. It was the first major conference on environmental issues.

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.
