" We can imagine that this complicated array of moving things which constitutes “the world” is something like a great chess game being played by the gods, and we are observers of the game. We do not know what the rules of the game are; all we are allowed to do is to watch the playing. Of course, if we watch long enough, we may eventually catch on to a few of the rules. The rules of the game are what we mean by fundamental physics. Even if we know every rule, however . . . what we really can explain in terms of those rules is very limited, because almost all situations are so enormously complicated that we cannot follow the plays of the game using the rules, much less tell what is going to happen next. We must, therefore, limit ourselves to the more basic question of the rules of the game. If we know the rules, we consider that we “understand” the world. "

" on his first visit to the Los Alamos Tech Area, when he had encountered von Neumann discussing theory with dark, intense Edward Teller, the “tremendously long formulae on the blackboard” had scared him. “Seeing all these complications of analysis, I was dumbfounded, fearing I would never be able to contribute anything.” But the equations stayed on the board from day to day, which meant to Ulam that the pace of invention was relatively slow, and he soon regained confidence.1340 “I found out that the main ability to have was a visual, and also an almost tactile, way to imagine the physical situations, rather than a merely logical picture of the problems.

" In 2008, some of the scientists who modeled the original 1983 nuclear winter scenario investigated the likely result of a theoretical regional nuclear war between India and Pakistan, a war they postulated to involve only 100 Hiroshima-scale nuclear weapons, yielding a total of only 1.5 megatons—no more than the yield of some single warheads in the U.S. and Russian arsenals. They were shocked to discover that because such an exchange would inevitably be targeted on cities filled with combustible materials, the resulting firestorms would inject massive volumes of black smoke into the upper atmosphere which would spread around the world, cooling the earth long enough and sufficiently to produce worldwide agricultural collapse. Twenty million prompt deaths from blast, fire, and radiation, Alan Robock and Owen Brian Toon projected, and another billion deaths in the months that followed from mass starvation—from a mere 1.5-megaton regional nuclear war.
