This is my only #Mathematics publication so far, but I am proud of it. It explores the domains of validity of approximations of the Fermi-Dirac distribution. It's a rich space as temperature T, mass m and chemical potential μ all compete. #Science #Physics #MathSky DOI: doi.org/10.1007/s107...

Nicușor Dan, the new president-elect of #Romania, is also a mathematician with 2 Olympiad gold medals (1987-88). He competed among Fields medalists Ngô Bảo Châu, Terence Tao, Stanislav Smirnov, and Elon Lindenstrauss. Wowza. #Science #Mathematics #MathSky

Terrence Tailo using #AI to help generate a #Mathematics proof using #Lean. This is the kind of stuff I hope AI gets used for more often. #MathSky #Science
