March 31 in Physics History - Births – Physicists born on March 31

Lawrence Bragg (31 Mar 1890 - 1 Jul 1971)

He was an Australian-English physicist and X-ray crystallographer who shared the Noble Prize in 1915 with his father. He formulated the fundamentals for the determination of crystal structure, also known as Bragg law. It relates the wavelengths of X-rays, the angle of incidence on a crystal, and the spacing of crystal planes for X-ray diffraction. The Braggs showed that sodium chloride does not have individual molecules in the solid and worked out the crystal structures of many substances.

Carlo Rubbia (Born on 31 Mar 1934)

He is an Italian physicist who joined CERN in 1960 and shared with the discovery of W particle and Z particle. These particles are the carriers of the weak forces which is involved in the radioactive decay of atomic nuclei.

Shin-ichiro Tomonaga (31 Mar 1906 - 8 Jul 1979)

He was a Japanese physicist who developed the basic principles of quantum electrodynamics with Feynman and Julian S. Schwinger. For their discovery, he shared the Noble Prize in 1965. He used the idea of intermediate coupling in which a third virtual particle affects the interaction between two particles. He used this to develop a quantum field theory.

George Green (14 Jul 1793 - 31 Mar 1841)

He was an English Mathematician who developed the mathematical theory of magnetism and electricity. He published many copies of complex work, an essay on the application of mathematical analysis to the Theories of electricity and magnetism in March 1828. Lastly, his essay became known to Lord Kelvin who understood it. He is known to have initiated modern mathematical theories of electricity.

Friedrich Hund (4 Feb 1896 - 31 Mar 1997)

He was a German physicist who is known for his empirical Hund’s Rules for atomic spectra which determines the lowest energy level for two electrons having the same n and l quantum numbers. The lowest energy state has the maximum total electron orbital angular momentum quantum number. It is also explained by the quantum theory of atoms.

Lyman Spitzer Jr. (26 Jun 1914 - 31 Mar 1997)

He was an American astrophysicist who made a major contribution to stellar dynamics and plasma physics. He studied interstellar dust grains and the motion of star clusters as well as magnetic fields. He was the driving force behind the Hubble telescope as he was the first who suggested placing a large telescope in space.

The First Spacecraft To Orbit The Moon

The first spacecraft to orbit the moon, Luna 10 was launched by the USSR in 1966. It completed its first orbit in 3 hours. It was powered by a battery and operated for 460 lunar orbits. It transmitted 219 radio data before 30 May 1966. Its other instruments investigated infrared emissions, radiation conditions, and solar plasma.
