quote for the day

"But again this overlooking of what is now plain almost to the verge of truism is no reflection on the perspicacity of creative geometers. Rather is it  merely another instance of the historical commonplace, emphasized long ago by W. Bolyai in connection with the final emergence of non-euclidean geometry after centuries of seemingly unnecessary struggle, that mathematical discoveries, like the springtime violets in the woods, have their season which no human effort can retard or hasten." - E.T. Bell
