Bernhard Riemann’s innovative approaches to Geometry

Bernhard Riemann’s innovative approaches to Geometry

Harald Sack
On September 17, 1826, influential German mathematician Bernhard Riemann was born. Riemann‘s profound and novel approaches to the study of geometry laid the mathematical foundation for Albert Einstein’s theory of relativity. He also made important contributions to the theory of functions, complex analysis, and number theory. “Nevertheless, it remains conceivable that the measure relations of space in the infinitely small are not in accordance with the assumptions of our geometry [Euclidean geometry],…

Wilhelm Ostwald and the Foundation of Modern Physical Chemistry

Wilhelm Ostwald and the Foundation of Modern Physical Chemistry

Tabea Tietz
On September 2, 1853, Baltic German chemist and Nobel Laureate Wilhelm Ostwald was born. He is credited with being one of the modern founders of the field of physical chemistry and received the 1909 Nobel Prize in Chemistry for his work on catalysis, chemical equilibria and reaction velocities. „Katalyse ist die Beschleunigung eines langsam verlaufenden chemischen Vorgangs durch die Gegenwart eines fremden Stoffes.“ – Wilhelm Oswald, 1894 Wilhelm Ostwald – Early Life…

Louis de Broglie and wave nature of matter

Louis de Broglie and wave nature of matter

Tabea Tietz
On August 15, 1892, French physicist and Nobel Laureate Louis de Broglie was born. He is best known for making groundbreaking contributions to quantum theory. He postulated the wave nature of electrons and suggested that all matter has wave properties. This concept is known as wave-particle duality or the de Broglie hypothesis. Louis de Broglie – Early Years Louis de Broglie attended the Lycée Janson of Sailly and decided to continue his…

Faster than the Speed of Light – Pavel Cherenkov and the Cherenkov Radiation

Faster than the Speed of Light – Pavel Cherenkov and the Cherenkov Radiation

Tabea Tietz
On July 15, 1904, Soviet physicist Pavel Alekseyevich Cherenkov was born. He shared the Nobel Prize in physics in 1958 with Ilya Frank [4] and Igor Tamm for the discovery of Cherenkov radiation, made in 1934. Cherenkov radiation is a faint blue light emitted by electrons passing through a transparent medium when their speed exceeds the speed of light in that medium. This sounds pretty weird, doesn’t it. With Einstein he have learned…

Hermann Minkowski and the four-dimensional Space-Time

Hermann Minkowski and the four-dimensional Space-Time

Tabea Tietz
On June 22, 1864, German mathematician Hermann Minkowski was born. Minkowski developed the geometry of numbers and used geometrical methods to solve problems in number theory, mathematical physics, and the theory of relativity. But he is perhaps best known for his work in relativity, in which he showed in 1907 that his former student Albert Einstein’s special theory of relativity can be understood geometrically as a theory of four-dimensional space–time, since known as the “Minkowski…

Heinrich Mann – Social Criticism, Marlene Dietrich, and Californian Exile

Harald Sack
On March 27, 1871, German novelist Luiz (Ludwig) Heinrich Mann was born. Being the elder brother of Nobel laureate Thomas Mann,[4] he wrote works with strong social themes. His numerous criticisms of the growth of fascism forced him to flee for his life after the Nazis came to power in 1933. His book “Professor Unrat” was freely adapted into the legendary movie “Der Blaue Engel” starring Marlene Dietrich in her first major role.…

Entangled in his own Legend – Karl May’s Fantastic Adventures

Harald Sack
On February 25, 1842, German writer of adventure novels Karl May was born. He is probably best known for his novels set in the American Old West with their main protagonists Winnetou and Old Shatterhand. Likewise he wrote similar popular adventures set in the Orient and Middle East in which the main protagonists were Kara Ben Nemsi and Hadschi Halef Omar. Being an efficient author and salesman, he often staged himself as…

Rudolf Mössbauer and the Recoilless Nuclear Resonance Absorption

Harald Sack
On January 31, 1929, German physicist and Nobel Laureate Rudolf Ludwig Mössbauer was born. He is best known for his 1957 discovery of recoilless nuclear resonance fluorescence for which he was awarded the 1961 Nobel Prize in Physics. This effect, called the Mössbauer effect, is the basis for Mössbauer spectroscopy. “Explain it! The most important thing is, that you are able to explain it! You will have exams, there you have to…

Friedrich Dürrenmatt’s ‘The Physicists’

Harald Sack
On January 5, 1921, Swiss author and dramatist Friedrich Dürrenmatt was born. Dürrenmatt was a proponent of epic theatre whose plays reflected the recent experiences of World War II. The politically active author‘s work included avant-garde dramas, philosophical crime novels, and macabre satire. Especially his play “The Physicists” (1961) deals with questions of scientific ethics and humanity‘s ability to handle its intellectual responsibilities. “A story is not finished, until it has taken…

John von Neumann – Game Theory and the Digital Computer

Harald Sack
On December 28, 1903, Hungarian and American pure and applied mathematician, physicist, inventor and polymath John von Neumann was born. He made major contributions to a number of fields including mathematics, physics, economics, computing, and statistics. He was a key figure in the development of game theory, the concepts of cellular automata, and the digital computer. He is definitely one of the candidates to write several biographical articles of, each with a…
