It seems that every practitioner of physics has had to wonder at some point why mathematics and physics have come to be so closely entwined. Opinions vary on the answer. ..Bertrand Russell acknowledged..'Physics is mathematical not because we know so much about the physical world, but because we know so little.' ..Mathematics may be indispensable to physics, but it obviously does not constitute physics.
War to me is very much like sex. You can develop a theory that says sex is primarily for the exchange of genetic material, or that it's a celebration of life, or you can make up 50,000 theories about why human beings have sex, all of which are in some sense true, all of which by themselves miss the point. Because the answer is extraordinarily complex. It may be for fun, it may be for reproduction, for financial reasons, any number of things.
Understanding is a lot like sex; it’s got a practical purpose, but that’s not why people do it normally.
We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.
There was a revolution going on at home. Why didn't I earn some money? Why didn't I do something practical, like chicken farming?
To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.
Sex is the greatest driving force on this planet. Christ, why are we living if we can't have a little fun? Sex is giving, and the more you give, the better lover you are.
My recollection of the higher school certificate, which involved a practical exam in physics, was being confronted with an experiment involving a sort of barometer arrangement, wondering why I couldn't make it work.
My ambition is to have this wonderful gift produce practical results for the future of commercial flying and for the women who may want to fly tomorrow's planes.
If you had a daily printout from the brain of an average twenty-four-year-old male, it would probably go like this: sex, need coffee, sex, traffic, sex, sex, what an asshole, sex, ham sandwich, sex, sex, etc
Unless and until you inspire the people, you will not get results. Imposition will never give you the results. Inspiration will always give you the results.
Useful knowledge, practical kindness, and beneficent laws -- these are not the Gospel; but, like philosophy, they are, or may be, its handmaids. They may make its task smooth and grateful; they may associate themselves with its victories, or they may prepare its way.
I was listening," the king said, aggrieved. "I closed my eyes to listen better." "What did you hear?" "I'm not sure," he said." That's why I was listening so closely. I may have to ask the baron to repeat some parts of his report on his grain tax." "I am sure you can arrange an appointment." "I am sure I can too.
I'd really like to see smart sex writing, writing that can take sex apart and try to put it back together, that doesn't just put a box around "sex writing" and give it glaring neon lights but assumes that sex is part of everything else in our lives.
Sex is hard to write about because you lose the universal and succumb to the particular. We all have our different favorites. Good sex is impossible to write about. Lawrence and Updike have given it their all, and the result is still uneasy and unsure. It may be that good sex is something fiction just can't do - like dreams. Most of the sex in my novels is absolutely disastrous. Sex can be funny, but not very sexy.
Fame, we may understand, is no sure test of merit, but only a probability of such: it is an accident, not a property, of a man; like light, it can give little or nothing, but at most may show what is given.
