Julian Schwinger and Quantum Electrodynamics

Julian Schwinger and Quantum Electrodynamics

On February 12, 1918, US-american theoretical physicist and Nobel Laureate Julian Seymour Schwinger was born. Schwinger is best known for his work on the theory of quantum electrodynamics (QED), in particular for developing a relativistically invariant perturbation theory, and for renormalizing QED to one loop order. Julian Seymour Schwinger was born in New York City, to Orthodox Jewish parents originally from Poland, Belle and Benjamin Schwinger, a prosperous garment manufacturer.…

Rolf Landauer and the Landauer Principle

On February 4, 1927, German-American physicist Rolf William Landauer was born. Landauer made important contributions in diverse areas of the thermodynamics of information processing, condensed matter physics, and the conductivity of disordered media. He is probably best known for the formulation of the eponymous Landauer Principle concerning the energy used during a computer‘s operation. Rolf Landauer was born on February 4, 1927, in Stuttgart, Germany. He emigrated to the United…
Abdus Salam’s  Electroweak Unifying Theory

Abdus Salam’s Electroweak Unifying Theory

On January 29, 1926, Pakistani theoretical physicist Mohammad Abdus Salam was born. Abdus Salam shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Steven Weinberg for his contribution to the electroweak unification theory. Mohammad Abdus Salam was born in Jhang, a small town in what is now Pakistan, into a Muslim Punjabi family. His father Chaudhry Muhammad Hussain was an official in the Department of Education of Punjab…
Hideki Yukawa and the Existence of Mesons

Hideki Yukawa and the Existence of Mesons

On January 23, 1907, Japanese theoretical physicist and the first Japanese Nobel laureate Hideki Yukawa was born. Yukawa shared the 1949 Nobel Prize for Physics for “his prediction of the existence of mesons on the basis of theoretical work on nuclear forces.” “Reality is cruel. All of the naivete is going to be removed. Reality is always changing, and it is always unpredictable. All of the balance is going to…
Stephen Hawking and the Hairy Black Holes

Stephen Hawking and the Hairy Black Holes

On January 8, 1942, English theoretical physicist, cosmologist and author Stephen William Hawking was born. Hawking’s principal areas of research are theoretical cosmology and quantum gravity. His scientific works include a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity, and the theoretical prediction that black holes emit radiation, often called Hawking radiation. Hawking was the first to set forth a theory of cosmology explained…
Satyendra Nath Bose and the Einstein-Bose Statistics

Satyendra Nath Bose and the Einstein-Bose Statistics

Satyendra Nath Bose (1894-1974) On January 1, 1898, Bengali Indian physicist Satyendra Nath Bose was born. Specialising in mathematical physics, Bose is best known for his work on quantum mechanics in the early 1920s, providing the foundation for Bose–Einstein statistics and the theory of the Bose–Einstein condensate. The class of particles that obey Bose–Einstein statistics, bosons, was named after Bose by Paul Dirac. Bose was born in Calcutta (now Kolkata),…
Robert J. Van de Graaff and the Van de Graaf Generator

Robert J. Van de Graaff and the Van de Graaf Generator

  On December 20, 1901, American physicist Robert Jemison Van de Graaff was born. Van de Graaff is specifically noted for his design and construction of high-voltage Van de Graaff generators that can be used as a particle accelerator in atomic research. Robert Jemison Van de Graaff received his master’s degree from The University of Alabama and began working at the Alabama Power Company afterwards. Van de Graaf later studied at…
Robert Millikan and the Millikan experiment

Robert Millikan and the Millikan experiment

On December 19, 1953, US-American physicist and Nobel laureate Robert Andrews Millikan passed away. Millikan was honored with the Nobel Prize for Physics in 1923 for his measurement of the elementary electronic charge and for his work on the photoelectric effect. Millikan‘s famous oil-drop experiment (1911) was far superior to previous determinations of the charge of an electron, and further showed that the electron was a fundamental, discrete particle. In…
Max Born and the statistical interpretation of the Wave Function

Max Born and the statistical interpretation of the Wave Function

On December 11, German physicist, mathematician, and Nobel Laureate Max Born was born, who was instrumental in the development of quantum mechanics. He also made contributions to solid-state physics and optics and supervised the work of a number of notable physicists in the 1920s and 1930s. Max Born was born in Breslau (now Wrocław, Poland), which at the time of Born’s birth was part of the Prussian Province of Silesia…
Henry Way Kendall and the Scattering of Particles

Henry Way Kendall and the Scattering of Particles

On December 9, 1926, American particle physicist and Nobel Laureate Henry Way Kendall was born. Kendall won the Nobel Prize in Physics in 1990 jointly with Jerome Isaac Friedman and Richard E. Taylor “for their pioneering investigations concerning deep inelastic scattering of electrons on protons and bound neutrons, which have been of essential importance for the development of the quark model in particle physics.” Henry Way Kendall was born in Boston…
