I read here, The number e, that this formula is not understood.
"In 1864 Benjamin Peirce had his picture taken standing in front of a blackboard on which he had written the formula above. In his lectures he would say to his students:-
Gentlemen, we have not the slightest idea what this equation means, but we may be sure that it means something very important.: Is there a meaning to this equation?
I tried to understand it with my calculator, but failed horribly.
With my limited understanding of i, that makes absolutely sense to me whatsoever.
I'm doing a research paper for undergraduate admissions into Cal Tech about 'e'.
