$Comprehensive presentation of the "Theorem of the Day", starting with a statement of this theorem. Archimedes’ Equiareal Map Theorem : Let S be the unit sphere defined relative to the x, y and z axes by x^2 + y^2 + z^2 = 1 and let S′ be the bounding cylinder defined by x^2 + y^2 = 1. Let f be the map f : (x, y, z) → (x / √(x^2 + y^2) , y / √(x^2 + y^2) , z) from S \{(0, 0, 1), (0, 0, −1)} to S ′ which takes a point P on the sphere having height zP, |zP| < 1, to the nearest point on the cylinder which has height zP and which is collinear with P and (0, 0, zP). Then f is an equiareal diffeomorphism.$

The Nazi war code had more settings than you can say out loud. It got broken not by trying them, but by noticing one thing the machine could never do. #MathsDidThat #maths #howitworks #stem #technology

13 septembre 1873 : #CeJourLà naissance de Constantin Carathéodory (†2/2/1950), mathématicien grec. On lui doit notamment des résultats en analyse fonctionnelle, géométrie (théorème de Carathéodory), théorie de la mesure (théorème d'extension de C.).

"It's interesting that although "or", "and" and "implies" have identical formal usage, we think of "or" and "and" as conjunctions and "implies" as a verb." – William Thurston (1946–2012)
