<<Emphasis added.>> Your profile shows that you're in the US. Also look at graduate programs in Materials Science and Engineering...

Using my magical mentor powers at the lay level, matter is a disturbance in quantum fields that permeate all space. Adding...

If that's how you want to define "matter", sure. As I said in post #2, "matter" is a word. There is no one single thing in the actual...

Energy is a conserved quantity associated with time-translation invariance of action (certain integral of lagrangian). That's general...

Electromagnetic radiation is energy. And is not a property of matter. Whatever matter is, calling energy a property of matter might be...

Or the fields in general.

Mass and energy are properties of matter (and of antimatter). Matter also has charge, spin and other properties, like colour charge etc.

He-3 does "take up room"; the fact that it is superfluid at low enough temperatures does not prevent it from occupying volume...

I would have said: matter is simply condensed energy. You might run into minor problems with this defintion because of energy-mass...

Undergraduate answer to an undergraduate question: matter is anything that has inertial mass, i.e., anything that resists acceleration...

I'll see if I can pull up a previous post of mine. There are interdisciplinary PhD Biophysics programs. If I recall correctly, there...

I would look into a mathematical physics program, such as: https://physics.uiowa.edu/research/mathematical-physics. Keep options open...

As a casual amateur, I like the analogy of a stone thrown into water. It could be continued to the waves hitting sand on the shore. If...

One other example is simply that if you charge metal ball or plate with static electricity, then you measure a potential difference...

It's not very helpful to think of light as made of photons. There are two theories of light. First, there is classical electromagnetism...
