Nathan Rosen (22 Mar 1909 - 18 Dec 1995)
He was an American-Israeli theoretical physicist who founded the Institute of Physics at Technion on Haifa. He collaborated with Boris Podolsky and Albert Einstein on the debate of quantum mechanics and later accepted the theory. The Einstein-Podolsky-Rosen theory of quantum mechanics was published in the Physical Review 1935.
Robert Andrews Millikan (22 Mar 1868 - 19 Dec 1953)
He was an American physicist who is famous for his oil-drop experiment (1911). It showed that the electron was a fundamental discrete particle. He was awarded the Nobel Prize for physics for “his work on the elementary charge of electricity and the photoelectric effect.” His work verified Niel Bohr’s theoretical formula for the hydrogen spectrum. Later, he coined the term ” cosmic rays” in 1925 when he was studying the radiation from outer space.
Burton Richter (22 Mar 1931 - 18 Jul 2018)
He was an American physicist who discovered the J/psi meson. It is a particle made up of a bound state of one charm quark and one anti charm quark. At Stanford, he designed and arranged a high-energy particle accelerator when he was a professor there. This accelerator enabled the discovery of the new particle. He shared the Noble Prize (1976) for physics for his discovery.
Ulugh Beg (22 Mar 1394 - 27 Oct 1449)
He was a Mongol astronomer and mathematician who was one of the greatest astronomers of his time. He discovered several errors in the calculations of the 2nd-century Alexandrian astronomer Ptolemy. He made a star map of 994 stars after Hipparchus. He built his own observatory in 1428 at Samarkand. He was assassinated by his son.

John Canton (31 Jul 1718 - 22 Mar 1772)
He was a British physicist and teacher who developed a new method of preparing artificial magnets and won the election to the Royal Society. He educated himself about science and became the first Englishman to repeat French experiments which verified that lightning was just a huge electric spark. He also invented an electroscope which was portable. He made the first observations of magnetic storms when he noted the irregularities in the compass needle during aurora borealis.

LASER
The first laser was patented in 1960 under the title “Masers and Maser Communications System.” It was the first laser to operate in the visible light spectrum. The patent was assigned to the Bell Telephone Laboratories where Arthur Schawlow and Charles Hard Townes had done the research.
International Ozone Agreement
The agreement of the Vienna Convention was adopted and opened for signature for the protection of the ozone layer. It was needed due to an increase in the health damage which results from a depleted ozone layer because of more UV-B radiation reaching the Earth’s surface. It includes weakened immune systems, an increased rate of skin cancers and eye cataracts, and more damage to the ocean ecosystem.
