A Quote by Christopher Pike

The physics are simple in theory, but in practice they are filled with the possibility for limitless error. — © Christopher Pike
The physics are simple in theory, but in practice they are filled with the possibility for limitless error.
There is a distinction, but no opposition, between theory and practice. Each to a certain extent supposes the other. Theory is dependent on practice; practice must have preceded theory.
Theoretically, I grant you, there is no possibility of error in necessary reasoning. But to speak thus "theoretically," is to uselanguage in a Pickwickian sense. In practice, and in fact, mathematics is not exempt from that liability to error that affects everything that man does.
Theory without practice is of little value, whereas practice is the proof of theory.Theory is the knowledge, practice the ability.
The problem of physics is how the actual phenomena, as observed with the help of our sense organs aided by instruments, can be reduced to simple notions which are suited for precise measurement and used of the formulation of quantitative laws. Experiment and Theory in Physics
I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.
What is especially striking and remarkable is that in fundamental physics, a beautiful or elegant theory is more likely to be right than a theory that is inelegant. A theory appears to be beautiful or elegant (or simple, if you prefer) when it can be expressed concisely in terms of mathematics we already have. Symmetry exhibits the simplicity. The Foundamental Law is such that the different skins of the onion resemble one another and therefore the math for one skin allows you to express beautifully and simply the phenomenon of the next skin.
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.
Critical reflection on practice is a requirement of the relationship between theory and practice. Otherwise theory becomes simply "blah, blah, blah, " and practice, pure activism.
The application of group theory to physics became one of the main branches of physics that I specialized in.
To me, what makes physics physics is that experiment is intimately connected to theory. It's one whole.
In sum: banking theory and practice, as immobilizing and fixating forces, fail to acknowledge men and women as historical beings; problem-posing theory and practice take the people's historicity as their starting point.
Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics.
A sound Physics of the Earth should include all the primary considerations of the earth's atmosphere, of the characteristics and continual changes of the earth's external crust, and finally of the origin and development of living organisms. These considerations naturally divide the physics of the earth into three essential parts, the first being a theory of the atmosphere, or Meteorology, the second, a theory of the earth's external crust, or Hydrogeology, and the third, a theory of living organisms, or Biology.
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.
In theory, practice should work like theory. In practice, it doesn't.
Which is to say that culture is not a reflex of political economy, but that society is now a reflex of key shifts in music theory and practice.... [Sampladelia is] the sound made by those early-twentieth-century discoveries in particle physics and relativiity theory, the projection of the minds of Einstein, Heisenbery, and Bohr, their fateful explorations of liquid time, curving space, uncertainty fields and relativity theorems, into densely configured and fully ambivalent android music tracks
