In everything, there are two kinds of development-analytical and synthetical. In the former the Hindus excel other nations. In the latter they are nil.
[Heisenberg's seminal 1925 paper initiating quantum mechanics marked] one of the great jumps—perhaps the greatest—in the development of twentieth century physics.
