A Quote by James Jeans
We may as well cut out group theory. That is a subject that will never be of any use in physics.

Never use a metaphor, simile, or other figure of speech which you are used to seeing in print. Never use a long word where a short one will do. If it is possible to cut a word out always cut it out. Never use the passive voice where you can use the active. Never use a foreign phrase a scientific word or a jargon word if you can think of an everyday English equivalent. Break any of these rules sooner than say anything outright barbarous.
The application of group theory to physics became one of the main branches of physics that I specialized in.
The standard theory may survive as a part of the ultimate theory, or it may turn out to be fundamentally wrong. In either case, it will have been an important way-station, and the next theory will have to be better.
A man has a right to use a saw, an axe, a plane, separately; may he not combine their uses on the same piece of wood? He has a right to use his knife to cut his meat, a fork to hold it; may a patentee take from him the right to combine their use on the same subject? Such a law, instead of enlarging our conveniences, as was intended, would most fearfully abridge them, and crowd us by monopolies out of the use of the things we have.
What the string theorists do is arguably physics. It deals with the physical world. They're attempting to make a consistent theory that explains the interactions we see among particles and gravity as well. That's certainly physics, but it's a kind of physics that is not yet testable.
No one must think that Newton’s great creation can be overthrown in any real sense by this [Theory of Relativity] or by any other theory. His clear and wide ideas will for ever retain their significance as the foundation on which our modern conceptions of physics have been built.
I always use my Les Paul. I have a Hamer as well. I use a Tele and an Esquire - once in a while, I will use a Strat, and I never use any pedals... except for in my car.
I think it laughable, frankly, that the physics community comes up with a theory for everything. There isn't one theory for everything. There is not one explanation. We may eventually have several theories that can tie things together nicely but there is not a single theory of everything.
Well, it may be all right in practice, but it will never work in theory
Evolutionary game theory was originally developed as an alternative to the hypothesis of group selection; now it is clear that game theory models postulate group selection, even if they do not use the g-word.
Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory.
If you're a physicist, for heaven's sake, and here is the experiment, and you have a theory, and the theory doesn't agree with the experiment, then you have to cut out the theory. You were wrong with the theory.
[Donald] Trump and all the Republicans believe in the theory of trickle down economics which is a theory discredited even by the author himself David Stockton. The theory suggests that if we take care of the people at the top, if we cut taxes for the wealthy, if we make sure they are doing really well, then the investments that they make in the economy and the jobs that will create, will make everything grow and it will have a trickle down effect on the rest of us.
No man may initiate the use of physical force against others. No man-or group or society or government-has the right to assume the role of a criminal and initiate the use of physical compulsion against any man. Men have the right to use physical force only in retaliation and only against those who initiate its use. The ethical principle involved is simple and clear-cut: it is the difference between murder and self-defense.
Even if we ignore the 'non-theoretical' knowledge which we acquire through experience (such as the knowledge of what something tastes like) and concentrate on theoretical knowledge, there is no good reason to think that physics can literally give the theory of everything. Here I want to be really pedantic. Although everything may be subject to physical law, not everything can be explained or described in physical terms. Physics has literally nothing to say about society, morality and the mind, for example - but of course these are parts of 'everything'.
I would never date a girl who insisted that I cut you out of my life. It’s non-negotiable. You want a piece of all this fabulousness?” He gestured at himself. “Well, my best friend comes along with it. I wouldn’t cut you out of my life, Clary, any more than I would cut off my right hand and give it to someone as a Valentine’s Day gift.” “Gross,” said Clary. “Must you?” He grinned. “I must.
