Quotes having the keyword Theory
I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes.
by Edward Witten (Mathematician, American , born in 1951) keywords: better, black, field, holes, insights, lead, new, ordinary, quantum, should, states, theories, theory, thought, understand, us , wrong If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We don't really know how big they are yet, but we hope to explore that in various ways.
by Edward Witten (Mathematician, American , born in 1951) keywords: big, conclude, dimensions, exist, explore, extra, hope, how, know, literally, nature, now, part, really, take, theory, various, ways, would , yet 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.

by Edward Witten (Mathematician, American , born in 1951) keywords: ask, happen, how, likely, might, parts, some, string, tell, tested , theory String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.
by Edward Witten (Mathematician, American , born in 1951) keywords: attempt, deeper, description, elementary, little, loop, nature, particle, point, string, theory, thinking , vibrating Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on using the extra dimensions.

by Edward Witten (Mathematician, American , born in 1951) keywords: change, classical, einstein, gravity, history, long, might, possible, quantum, speculation, theory, topology , unlike Thought and theory must precede all salutary action; yet action is nobler in itself than either thought or theory.
by Virginia Woolf (Author, British , born in 1970) keywords: action, either, itself, must, nobler, precede, salutary, than, theory, thought , yet I am relying on the theory that playing golf is just like riding a bike and that I haven't forgotten how.

by Francis Parker Yockey (Writer, American , born in 1917) keywords: adrift, aim, boundary, his, intellectual, politician, politics, theory , true 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.
by Mao Zedong (Leader, Chinese , born in 1893) keywords: change, direct, eating, experience, genuine, know, knowledge, methods, must, originates, part, revolution, take, taste, theory, want , yourself I should point out, however, that at first some difficulty was experienced in observing the phenomena predicted by the theory, owing to the extreme smallness of the variations in the period of oscillation.
by Pieter Zeeman (Physicist, Dutch , born in 1865) keywords: difficulty, experienced, extreme, first, however, observing, oscillation, out, owing, period, phenomena, point, predicted, should, smallness, some, theory , variations 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.
by Pieter Zeeman (Physicist, Dutch , born in 1865) keywords: assume, atom, basis, contains, each, electron, limit, line, molecule, moving, ourselves, single, spectral, suffices , theory The theory of relativity worked out by Mr. Einstein, which is in the domain of natural science, I believe can also be applied to the political field. Both democracy and human rights are relative concepts - and not absolute and general.
