" For many years I have been saying that I would like to write a book (or series of books) called Physics for Mathematicians. Whenever I would tell people that, they would say, “Oh good, you're going to explain quantum mechanics, or string theory, or something like that”. And I would say, “Well that would be nice, but I can't begin to do that now; first I have to learn elementary physics, so the first thing I will be writing will be Mechanics for Mathematicians”. So then people would say, “Ah, so you're going to be writing about symplectic structures”, or something of that sort. And I would have to say, “No, I'm not trying to write a book about mathematics for mathematicians, I'm trying to write a book about physics for mathematicians”; …… it's elementary mechanics that I don't understand. … I mean, for example, that I don't understand this – lever.
... Most of us know the law of the lever, but this law is simply a quantitative statement of exactly how amazing the lever is, and doesn't give us a clue as to why it is true, how such a small force at one end can exert such a great force at the other.
Now physicists all agree that Newton's Three Laws are the basis from which all of mechanics follows, but if you ask for an explanation of the lever in terms of these three laws, you will almost certainly not get a satisfactory answer. "

" When one thinks of all the people who support or have supported Fascism, one stands amazed at their diversity. What a crew! Think of a programme which at any rate for a while could bring Hitler, Petain, Montagu Norman, Pavelitch, William Randolph Hearst, Streicher, Buchman, Ezra Pound, Juan March, Cocteau, Thyssen, Father Coughlin, the Mufti of Jerusalem, Arnold Lunn, Antonescu, Spengler, Beverley Nichols, Lady Houston, and Marinetti all into the same boat! But the clue is really very simple. They are all people with something to lose, or people who long for a hierarchical society and dread the prospect of a world of free and equal human beings. Behind all the ballyhoo that is talked about ‘godless’ Russia and the ‘materialism’ of the working class lies the simple intention of those with money or privileges to cling to them. Ditto, though it contains a partial truth, with all the talk about the worthlessness of social reconstruction not accompanied by a ‘change of heart’. The pious ones, from the Pope to the yogis of California, are great on the’ change of heart’, much more reassuring from their point of view than a change in the economic system. "
