Ivan Matveevich Vinogradov and the Goldbach Conjecture

Harald Sack
On September 14, 1891, Soviet mathematician Ivan Matveevich Vinogradov was born. Vinogradov is best known for his contributions to the analytical theory of numbers, including a partial solution of the Goldbach conjecture proving that every sufficiently large odd integer can be expressed as the sum of three odd primes. Ivan Matveevich Vinogradov – Youth and Education Ivan Matveevich Vinogradov was born to Matvei Avraam’evich Vinogradov, a priest in Milolyub, a village in…

Carl Størmer and the Mathematical Model of the Formation of Aurorae

Tabea Tietz
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…

Aryabhata and Early Indian Mathematics

Harald Sack
In 476 CE, Indian mathematician and astronomer Aryabhata was born. Aryabhata is the earliest Indian mathematician whose work and history are available to modern scholars. In his work “Ganita” Aryabhata names the first 10 decimal places and gives algorithms for obtaining square and cubic roots, using the decimal number system. He also came up with an approximation of pi and the area of a triangle. “Aryabhata is the master who, after reaching…

Oliver Heaviside changed the Face of Telecommunications

Tabea Tietz
On May 18, 1850, English self-taught electrical engineer, mathematician, and physicist Oliver Heaviside was born. Heaviside adapted complex numbers to the study of electrical circuits, invented mathematical techniques for the solution of differential equations, reformulated Maxwell’s field equations in terms of electric and magnetic forces and energy flux, and independently co-formulated vector analysis. “However absurd it may seem, I do in all seriousness hereby declare that I am animated mainly by philanthropic motives.…

Pafnuty Chebyshev and the Chebyshev Inequality

Tabea Tietz
On May 16, 1821, Russian mathematician Pafnuty Lvovich Chebyshev was born. Chebyshev is remembered primarily for his work on the theory of prime numbers, including the determination of the number of primes not exceeding a given number. Moreover, he is noted for his work in the fields of probability, statistics, mechanics, and number theory. “To isolate mathematics from the practical demands of the sciences is to invite the sterility of a cow shut…

Edward Kasner and how Google got its Name

Harald Sack
On April 2, 1878, American mathematician Edward Kasner was born. Kasner is best remembered for introducing the term “googol” for a very large number, which you might probably already know, at least if you know the story how the search engine “Google” got its name. Moreover, he is known also for the Kasner metric and the Kasner polygon. Edward Kasner – Early Life Edward Kasner was born among eight siblings in New…
