Janos Bolyai and the Discovery of Non-Euclidian Geometry

Janos Bolyai and the Discovery of Non-Euclidian Geometry

On December 15, 1802, Hungarian mathematician János Bolyai was born. He is most famous for being one of the founders of non-euclidian geometry, a geometry that differs from Euclidean geometry in its definition of parallel lines. Bolyai was born in the Transylvanian town of Kolozsvár (Klausenburg), then part of the Habsburg Empire (now Cluj-Napoca in Romania), the son of Zsuzsanna Benkő and the well-known mathematician Farkas Bolyai. Farkas Bolyai always wanted his…

God made the integers, all the rest is the work of man – Leopold Kronecker

God made the integers, all the rest is the work of man – Leopold Kronecker

On December 7, 1823, German mathematician Leopold Kronecker was born, who worked on number theory and algebra. He criticized Cantor’s work on set theory, and his most cited quote says, “Die ganzen Zahlen hat der liebe Gott gemacht, alles andere ist Menschenwerk” (traditionally rendered: “God made natural numbers; all else is the work of man“.) Leopold Kronecker was born in Liegnitz, Prussia (now Legnica, Poland) in a wealthy Jewish family to Isidor and Johanna…

Eugenio Beltrami and Non-Euclidian Geometry

Eugenio Beltrami and Non-Euclidian Geometry

Eugenio Beltrami (1835–1900) On November 16, 1835, Italian mathematician Eugenio Beltrami was born. He is most notable for his work concerning differential geometry and mathematical physics. His work was noted especially for clarity of exposition. He was the first to prove consistency of non-Euclidean geometry by modeling it on a surface of constant curvature, the pseudosphere. Eugenio Beltrami was born in Cremona in Lombardy, then a part of the Austrian Empire, and now part of Italy. The son…

Friedrich Bessel and the Distances of Stars

Friedrich Wilhelm Bessel (1784-1846) [1] On July 22, 1784, German mathematician and astronomer Friedrich Wilhelm Bessel was born. He is probably best known for his works in mathematics, where he discovered the eponymous Bessel-functions, which are critical for the solution of certain differential equations. Friedrich Wilhelm Bessel was born in Minden, Westphalia (today Germany), as second son of a civil servant. Bessel attended the Gymnasium in Minden for four years but he did…

Ferdinand de Saussure and the Study of Language

Ferdinand de Saussure (1857-1913) On November 26, 1857, Swiss linguist and semiotician Ferdinand de Saussure was born. His ideas laid the foundation for many significant developments both in linguistics and semiotics in the 20th century. Moreover, de Saussure is widely considered one of the fathers of 20th-century linguistics and together with Charles Sanders Peirceone of two major fathers of semiotics. Ferdinand de Saussure enrolled at the University of Geneva and started his graduate…

August Ferdinand Möbius and the Beauty of Geometry

August Ferdinand Möbius (1790 – 1868) On November 17, 1790, German mathematician and astronomer August Ferdinand Möbius was born. He is best known for his discovery of the Möbius strip, a non-orientable two-dimensional surface with only one side when embedded in three-dimensional Euclidean space. August Möbius’ interest in mathematics evolved early, but it is said that his teacher hid several mathematical books from the curious boy to guarantee a widely ranged education…

Gottlob Frege and the Begriffsschrift

Gottlob Frege (1848-1925) On November 8, 1848, German mathematician, logician and philosopher Gottlob Frege was born. He is considered as one of the fathers of modern mathematical logic and has developed the Begriffsschrift, an approach to put classical philosophical logic into a formal mathematical language. While he was mainly ignored by the intellectual world when he published his writings, Giuseppe Peano and Bertrand Russell introduced his work to later generations of logicians…
