Title: Master of Exposition
Product review: It's an excellent book. The best parts forwe were the chapters on Matrices and onHarmonic Analysis. An outstanding aspectof the latter chapter is Lanczos's expositionof the motivation behind the Fourier integral(transform) and its basic theory. The qualityof the writing is superb, very classicaland lucid.It cannot, of course, serve as a textbook.But if you're taking a Fourier theorycourse using Stein and Shakarchi's book, say,as I am currently, then it's a very handybook that can complement abstract theorywith physical intuition.
