May 23 at 20:12 comment added Ponce Interesting that Bourbaki ended up using the first letter of the german words for the definitive number systems symbols, considering the political situation in those years, probably Weil was the main responsible for this

Apr 13, 2010 at 1:34 comment added François G. Dorais Apparently Z, Q, R are all eventually due to Bourbaki and stand for the German Zahlen, Quotient, Reelle. However, they were all randomly used by someone else before... jeff560.tripod.com/nth.html
Apr 13, 2010 at 0:21 comment added François G. Dorais I was under the impression that Q, R, C are all from French (Quotient, Réel, Complexe). I doubt the Romans needed a symbol for Q...
Dec 11, 2009 at 20:47 comment added Konrad Voelkel maybe \mathbb R comes from the french "nombres reelles" or the english "real numbers" instead? how do you know? For complex numbers, I would even argue for a german/latin origin, since germans used "complex" instead of "komplex" at the time of Gauss.
