    Moving from series (periodic) to transforms (aperiodic), Körner covers the $L^1$ and $L^2$ theories. He includes a brilliant discussion of the Uncertainty Principle—not from quantum mechanics, but from the Fourier relationship: a function and its transform cannot both be sharply localized.

    Most Fourier books stop at heat flow or vibrations. Körner takes a breathtaking left turn into the Riemann Zeta Function. He uses Fourier analysis to prove that $\sum_n=1^\infty 1/n^2 = \pi^2/6$ (the Basel problem) and discusses the distribution of prime numbers. This section alone justifies the book’s price.
