When the physicist poses the question, "What does it mean to do physics?" or "What is research in physics?" - his question is a preliminary question. Clearly, when you ask a question like that, and try to answer it, you are not "doing physics." Or rather you are no longer doing physics. But when you ask yourself, "What does it mean to do philosophy?" then you actually are "doing philosophy" - this is not at all a "preliminary" question but a truly philosophical one: you are right at the heart of the business.

...what I mean by Socialism is a condition of society in which there should be neither rich nor poor, neither master nor master's man, neither idle nor overworked, neither brainslack brain workers, nor heartsick hand workers, in a word, in which all men would be living in equality of condition, and would manage their affairs unwastefully, and with the full consciousness that harm to one would mean harm to all-the realisation at last of the meaning of the word commonwealth.

It isn't that some gay will get some rights. It's that everyone else in our state will lose rights. For instance, parents will lose the right to protect and direct the upbringing of their children. Because our K-12 public school system, of which 90% of all youth are in the public school system, they will be required to learn that homosexuality is normal, equal and perhaps you should try it. And that will occur immediately, that all schools will begin teaching homosexuality.

If physics is too difficult for the physicists, the nonphysicist may wonder whether he should try at all to grasp its complexities and ambiguities. It is undeniably an effort, but probably one worth making, for the basic questions are important and the new experimental results are often fascinating. And if the layman runs into serious perplexities, he can be consoled with the thought that the points which baffle him are more than likely the ones for which the professionals have not found satisfactory answers.

"Everyone is bisexual': "I've always had as many powerful, creative ladies in my life as I have men, and you could probably describe some of those relationships as romantic. I think everyone's bisexual to some degree or another; it's just a question of whether or not you choose to recognise it and embrace it. Personally, I think choosing between men and women is like choosing between cake and ice cream. You'd be daft not to try both when there are so many different flavours.”.

To the pure geometer the radius of curvature is an incidental characteristic - like the grin of the Cheshire cat. To the physicist it is an indispensable characteristic. It would be going too far to say that to the physicist the cat is merely incidental to the grin. Physics is concerned with interrelatedness such as the interrelatedness of cats and grins. In this case the "cat without a grin" and the "grin without a cat" are equally set aside as purely mathematical phantasies.
