Sir Andrew Noble and the Science of Ballistics

Sir Andrew Noble and the Science of Ballistics

On September 13, 1831, Scottish physicist Andrew Noble was born. Noble was a gunnery expert, known as a founder of the science of ballistics. He invented the chronoscope, a device for measuring very small time intervals, and used it to measure the velocity of shot in gun barrels. Andrew Noble was commissioned in the Royal Artillery in 1849. He later became secretary of the Royal Artillery Institution. Noble was secretary…
Victor Ambartsumian and Theoretical Astrophysics

Victor Ambartsumian and Theoretical Astrophysics

On September 5, 1908, Soviet astronomer and astrophysicist Viktor Amazaspovich Ambartsumian was born. Ambartsumian is well known as one of the founders of theoretical astrophysics. He worked in the field of physics of stars and nebulae, stellar astronomy, dynamics of stellar systems and cosmogony of stars and galaxies, and contributed to mathematical physics. Victor Ambartsumian was the son of the prominent philologist and writer Hamazasp Asaturovich Ambartsumian, the translator of Homer’s Iliad…
Carl Størmer and the Aurorae

Carl Størmer and the 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…
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 was employed as an engineer by the Lighthouses…
Norman Ramsey and the Oscillatory Field Method

Norman Ramsey and the Oscillatory Field Method

On August 27, 1915, American physicist and Nobel Laureate Norman Foster Ramsey Jr. was born. Ramsey was awarded the 1989 Nobel Prize in Physics, for the invention of the separated oscillatory field method, which had important applications in the construction of atomic clocks. Norman Foster Ramsey Jr. was born in Washington, D.C., to Minna Bauer Ramsey, an instructor at the University of Kansas, and Norman Foster Ramsey, an officer in…
Georges Charpak and the Multiwire Proportional Chamber

Georges Charpak and the Multiwire Proportional Chamber

On August 1, 1924, French physicist and Nobel Laureate Georges Charpak was born. Charpak was awarded the Nobel Prize for Physics in 1992 for his invention and development of subatomic particle detectors, in particular the multiwire proportional chamber, a breakthrough in the technique for exploring the innermost parts of matter. “If there’s one thing to do, it’s to engage in education.” George Charpak Georges Charpak was born Jerzy Charpak to…
Charles H. Townes and the Maser

Charles H. Townes and 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. Charls H. Townes was born in Greenville, South Carolina, the son of Henry Keith Townes, an attorney, and Ellen Sumter Townes. As…
Iosif Shklovsky and Intelligent Life in the Universe

Iosif Shklovsky and 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…
J. Hans D. Jensen and the Uranium Club

J. Hans D. Jensen and the Uranium Club

On June 25, 1907, German nuclear physicist Johannes Hans Daniel Jensen was born. During World War 2, Jensen worked on the German nuclear energy project, known as the Uranium Club, in which he made contributions to the separation of uranium isotopes. Jensen shared half of the 1963 Nobel Prize in Physics with Maria Goeppert-Mayer for their proposal of the nuclear shell model. Hans Jensen was appointed Privatdozent at the University of Hamburg…
Victor Hess and the Ultra Radiation

Victor Hess and the Ultra Radiation

On June 24, 1883, Austrian-American physicist, and Nobel laureate in physics Victor Francis Hess was born. Hess shared the Nobel Prize for Physics with Carl Anderson in 1936 for his discovery of cosmic rays. Victor Franz Hess was born near Peggau in Styria, Austria, to Vinzenz Hess, a royal forester in Prince Louis of Oettingen-Wallerstein’s service, and his wife Serafine Edle von Grossbauer-Waldstätt. He attended secondary school at Graz Gymnasium…
