Taken jointly, those lectures characterize a distinct exploration of the basic obstacles of electronic computers.Feynman’s philosophy of studying and discovery comes via strongly in those lectures. He continually issues out the advantages of being silly with recommendations and dealing out suggestions to difficulties in your own-before the again of the e-book for the solutions.
