@Iyengar If you loved Fearless Symmetry, then you should read Symmetry and the Monster by Mark Ronan amazon.com/Symmetry-Monster-Greatest-Quests-Mathematics/dp/…

comment Finding $F(x)$ so that $F'(x) = e^{-x^2}$
I see. Examining the graph of $\exp(-x^2)$ I see that $f'(0)$ is indeed $0$ but did you surmise this a different way?

revised If $\exp(itH) A \exp(-itH) = A$ for all $t$, do $A$ and $H$ commute?
Finicky. Just put the title into LaTeX and put "for all t" into "for all $t$"

Sorry about that, I left my computer and hadn't come back to accept it yet because when I posted that it said I had to wait 45 minutes

comment Proving an Integral Theorem
I see now. So the middle quantity is bounded by $m, M$ and $f$ must take the value of some $c$ so that $f(c) \in [m,M]$, and so this necessarily means that $c\in [a,b]$?
