In my own opinion, though less well known than Einstein, Von Neumann ranked close to Einstein in terms of genius. Like Einstein, he didn't merely bring in a single profound new idea; but seemed to change

Only in the last chapter did the authors remind us that Einstein later put two of these three into question, and even the kinetics. Halliday and Resnick reasoned, correctly | think, that we sometimes learn more eff

vailable for business to borrow and invest. But business lacked the “animal spirits” to take such a risk ina slump. We saw the same story after 2008. Keynes’ proposal was for government to do the borrowing and investing instead. That’s part of the “fiscal policy” I described in Chapter 1. Here we tend to

saving is invested, as I use the word, but finds different returns. Saving under the mattress is investment at zero return, and drops output just as Keynes said. Investment at the current average return keeps output unchanged. That’s what Keynes meant. But investment at lower returns lowers output, and c

words alone. One less something nearer zero, whether that something (the thrift index) is positive or negative, is nearer one. The wonderful books of Einstein (with Enfeld) and Steven Hawking, not to mention Mill, show that even calculus can be put that way. My task has been to follow their tough act. But I

One of the features of his General Theory of 1936 was a kind of double-

Keynes’ teacher Alfred Marshall agreed with Farr in 1990’. As I read this passage, Marshall interpreted maintenance consumption as investment. So did B. F.
