Charles Barkla (7 Jun 1877 - 23 Oct 1944)

He was an English physicist who worked on x-ray scattering. For his work, he was awarded the Nobel Prize for Physics in 1917. His techniques are used to investigate the atomic structures. He also showed that the scattering of X-rays by a gas depends on the molecular weight of the gas in 1903. His experiments showed that X-rays are electromagnetic radiation just like light. Later he also discovered that each element has its own x-ray spectrum.

Bernard F. Burke (7 June 1928 - 5 August 2018)

He was an American astronomer who, by chance, found a radio signal that resembled a short burst of static similar to interference by lightning on home radios. After studying the period of the signal, they pinpointed Jupiter as the source. This was the first time that radio sound was detected from a planet in our solar system. Later it was shown that the radio where polarized involving a magnetic field.

John Sealy Edward Townsend (7 Jun 1868 - 16 Feb 1957)

He was a British physicist who was the first to study the electrical conduction in gases. He was the first to measure the unit of electrical charge directly in 1898. He developed the falling drop method for measuring e. For this, he used saturated clouds of charged water droplets. He was also the first to explain how electric discharges pass through gases.

Joseph von Fraunhofer (6 Mar 1787 - 7 Jun 1826)

He was a German physicist who first studied the dark lines in the solar spectrum, which were seen by Wollaston in 1802. He measured 576 lines but could not explain them. These are caused by the selective absorption of those wavelengths by atoms of elements. He used a diffraction grating instead of a prism to disperse the spectrum. He also invented a heliometer.

Alexis Bouvard (27 Jun 1767 - 7 Jun 1843)

He was a French astronomer who was also the director of the Paris Observatory. He discovered eight comets and wrote table astronomiques of Jupiter and Saturn. His table predicted accurately the orbital locations of Jupiter and Saturn. His tables for Uranus failed that led him to hypothesize that an unknown perturbing body is causing the irregularities. This led to the discovery of Neptune.

Karl Kelchner Darrow (26 Nov 1891 - 7 Jun 1982)

He was an American physicist who later became a science writer. His writings included critical reviews, encyclopedia entries, and 4 science books. He could interpret physics with clarity whether to a gathering of the scientist or wider intellectual audiences. He gave many lectures at the Lowell institute in 1935. He was invited by four universities at different times as a visiting professor.

European Nuclear Laboratory

A European Nuclear Physics laboratory was proposed by Nobel Prize winner, Isidor I. Rabi in 1950. The US was represented by him at the 5th General Conference.
