A Quote by Richard P. Feynman

Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics.

Musically, swing pretty much dominated in the '30s. And into the late '30s, swing is beginning to change over to bebop in the early '40s, which is exactly when this new science of theoretical physics, particularly theoretical atomic physics, was really coming to the fore.

Chris Eigeman

All theoretical chemistry is really physics; and all theoretical chemists know it.

Richard P. Feynman

When I was a college student at Yale, I was studying physics and mathematics and was absolutely intent on becoming a theoretical physicist.

James Rothman

If the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.

Pierre Duhem

I recognize that many physicists are smarter than I am-most of them theoretical physicists. A lot of smart people have gone into theoretical physics, therefore the field is extremely competitive. I console myself with the thought that although they may be smarter and may be deeper thinkers than I am, I have broader interests than they have.

Linus Pauling

For her PhD, Maria Goeppert Mayer, a theoretical physicist, came up with the idea of multi-photon physics. That means an atom absorbs two or more photons simultaneously.

Donna Strickland

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'.

Tim Crane

Now these two questions Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics. Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.

Pierre Duhem

I'm constantly meeting people that I hurt, you know? This is not - when I go and talk about these things, this is not a theoretical - it's not a theoretical apology. It's something that I live every day.

Megan Phelps-Roper

Theoretical physics hardly requires any research funding, so I never felt the need. The overall government and institutional support has been good enough for my work.

Ashoke Sen

This is often the way it is in physics - our mistake is not that we take our theories too seriously, but that we do not take them seriously enough. It is always hard to realize that these numbers and equations we play with at our desks have something to do with the real world. Even worse, there often seems to be a general agreement that certain phenomena are just not fit subjects for respectable theoretical and experimental effort.

Steven Weinberg

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system.

Talcott Parsons

If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom.
