On October 29, 1783, Jean d'Alembert passed away. He was a French mathematician known for d'Alembert's principle and d'Alembert's ratio test. He also provided an almost complete proof of the fundamental theorem of algebra. #MathematicalAnalysis

On October 30, 1906, Andréi Tikhonov was born. He was a Russian mathematician known for his contributions to topology and functional analysis. He was responsible for defining the product topology and is famous for Tikhonov's theorem. #Topology

On October 30, 1626, Willebrord Snell passed away. He was a Dutch physicist famous for the law of refraction that bears his name. He introduced several important discoveries regarding the size of the Earth and made improvements to the applied method of calculus.

On October 31, 1815, Karl Weierstrass was born. He was a German mathematician known as the father of modern analysis. He provided the current definitions of continuity, derivative, and limit of a function. #MathematicalAnalysis

On October 31, 1988, Theodor Schneider passed away. He was a German mathematician especially known for proving the Gelfond-Schneider theorem. Before this result, only a few transcendental numbers were known, such as π or e. #Algebra

On November 2, 1815, George Boole was born. He was a British mathematician best known for inventing Boolean algebra, which laid the foundations of modern computational arithmetic. For this reason, he is considered one of the founders of computer science. #Algebra #ComputerScience

On November 3, 1867, Martin Wilhelm Kutta was born. He was a German mathematician and physicist who worked in numerical analysis. He is best remembered for the Runge–Kutta method. #NumericalAnalysis #DifferentialEquation

On November 3, 1918, Aleksandr Lyapunov passed away. He was a Russian mathematician known for his contributions to probability theory and celestial mechanics. Moreover, he was one of the pioneers of stability theory. #DifferentialEquation

On November 3, 1967, Alexander Aitken passed away. He was a New Zealand mathematician with an extraordinary memory. He worked in statistics and numerical analysis. He is remembered for Aitken’s Δ^2 process and Aitken’s acceleration theorem. #NumericalAnalysis

On November 5, 1879, James Maxwell passed away. He was a physicist who succeeded in unifying electricity, magnetism, and light as different manifestations of a single phenomenon. Maxwell’s equations are regarded as the “second great unification of physics”.

On November 5, 1934, Walther von Dyck passed away. He was a German mathematician who made significant contributions to group theory and graph theory. He is recognized as the first to define a group in terms of generators and relations, and he is remembered for Dyck’s theorem.

On November 7, 1867, Marie Curie was born. Her achievements include the first studies on the phenomenon of radioactivity (a term she herself coined), the discovery of two elements —polonium and radium—, and the development of techniques for isolating radioactive isotopes...

On November 7, 1968, Aleksandr Gelfond passed away. He was a Russian mathematician best known for proving the Gelfond–Schneider theorem. Before this result, only a few transcendental numbers were known, such as π or e. #Algebra

On November 8, 1719, Michel Rolle passed away. He was a French mathematician known for Rolle’s theorem, as well as for having produced the first publication in Europe on what is now known as the Gauss–Jordan elimination method, which he called the substitution method. #Calculus

On November 8, 1848, Gottlob Frege was born. He was a German logician and a pioneer of symbolic logic. He also proposed the idea that mathematics could be reduced to logic. He is remembered for Frege’s theorem and for the definition he provided of the set N. #Logic

On November 8, 1868, Felix Hausdorff was born. He was a German mathematician considered one of the founders of modern topology. He also made significant contributions to set theory, measure theory, functional analysis, and the theory of functions. #Topology

On November 10, 1829, Elwin Bruno Christoffel was born. He was a German physicist who worked on potential theory, invariant theory, and developed in depth the Riemann tensor. The Christoffel symbols and the Schwarz–Christoffel mapping are named in his honor.

On October 11, 1940, Vito Volterra passed away. He was an Italian mathematician whose research ranged from functional analysis to integral and differential equations. He is best known for introducing the Volterra integral equations. #DifferentialEquation
