On the other hand, we don't understand the theory too completely, and because of this fuzziness of spacetime, the very concept of spacetime and spacetime dimensions isn't precisely defined. ↗

So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested. ↗

There was a long history of speculation that in quantum gravity, unlike Einstein's classical theory, it might be possible for the topology of spacetime to change. ↗

In theory, I'd like to work in a group. But the group I'd like to work in, all the musicians in them are long since dead. ↗

If you want to know the taste of a pear, you must change the pear by eating it yourself. If you want to know the theory and methods of revolution, you must take part in revolution. All genuine knowledge originates in direct experience. ↗

On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron. ↗

No theory is good unless it permits, not rest, but the greatest work. No theory is good except on condition that one use it to go on beyond. ↗

It was a question of helping a man prepare in the way that suits him best. The theory is if you give a man responsibility for his own actions, then it is up to him to accept that responsibility. ↗

The one thing I do have is good ears. I don't mean perfect pitch, but ears for picking things up. I developed my ear through piano theory, but I never had a guitar lesson in my life, except from Eric Clapton off of records. ↗

The piano is a universal instrument. If you start there, learn your theory and how to read, you can go on to any other instrument. ↗
