Feynman's mathematical methods ARE available !,
By A Customer
This review is from: Lectures on Physics (Hardcover)
In the introduction to these classics, Feynman regrets not devoting "volume 3" to mathematical methods, instead of to quantum mechanics. However help is at hand, if one can find it. "Mathematical methods" by Matthews and Walker (Addison Wesley) is in the style of Feynman, one of the authors being a former student of his.
