Carl Størmer and the Mathematical Model of the Formation of Aurorae

Carl Størmer and the Mathematical Model of the Formation of Aurorae

On September 3, 1874, Norwegian mathematician and geophysicist Carl Størmer was born. Carl Størmer is known both for his work in number theory and for studying the movement of charged particles in the magnetosphere and the formation of aurorae. He also contributed both important photographic observations and mathematical data to the understanding of the polar aurora, of stratospheric and mesospheric clouds, and of the structure of the ionosphere. The discovery of the Van Allen…

André Blondel and the Oscillograph

André Blondel and the Oscillograph

On August 28, 1863, French engineer and physicist André-Eugène Blondel was born. Blondel is the inventor of the electromechanical oscillograph, a device that allowed electrical researchers to observe the intensity of alternating currents, and a system of photometric units of measurement, such as the lumen and other new photometric units for use in photometry, based on the metre and the Violle candle. André Blondel – Early Years André Blondel was the only son of…

Charles H. Townes and the Invention of the Maser

On July 28, 1915, American physicist and Nobel Laureate Charles Hard Townes was born. Townes was known for his work concerning the theory and application of the maser, for which he obtained the fundamental patent, and other work in quantum electronics associated with both maser and laser devices. “I feel that very rarely have I done any work in my life. I have a good time. I’m exploring. I’m playing a game,…

Jordan Carson Mark and the Development of Thermonuclear Weapons

On July 6, 1913, Canadian mathematician Jordan Carson Mark was born. Mark is best known for his work on developing nuclear weapons for the United States at the Los Alamos National Laboratory. He oversaw the development of new weapons, including the hydrogen bomb in the 1950s. On the hydrogen bomb project he was able to bring together experts like Edward Teller, Stanislaw Ulam and Marshall Holloway despite their personal differences. Jordan Carson…

Iosif Shklovsky and the Search for Intelligent Life in the Universe

Iosif Shklovsky and the Search for Intelligent Life in the Universe

On July 1, 1916, Soviet astronomer and astrophysicist Iosif Shklovsky was born. Shklovsky identified the continuum radiation of the Crab Nebula as synchrotron radiation, and he linked x-ray stars to binary systems containing a neutron star. He is also remembered for his 1962 book on extraterrestrial life, the revised and expanded version of which was co-authored by American astronomer Carl Sagan in 1966 as ‘Intelligent Life in the Universe‘. Iosif Shklovsky – The…

Charles Barkla and X-Ray Characteristics of the Chemical Elements

On June 7, 1877, British physicist Charles Glover Barkla was born. Barkla received the Nobel Prize in Physics for his work in X-ray spectroscopy. In particular for his work on X-ray scattering. This technique is applied to the investigation of atomic structures, by studying how X-rays passing through a material and are deflected by the atomic electrons. Charles Berkla – Early Years of a Physicist Charles Barkla was born in Widnes, England, to John…
