Energy is a concept that has been coined by physicists. There is no observable thing known as energy anywhere.
The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.
Every physicist knows that things connect with each other. To isolate things is not the way the universe works - winning best actor is arbitrary.
To a theoretical physicist, there is no greater joy than to see that this curious activity we call calculation - the depositing of ink on paper, followed by throwing away the paper and depositing new ink on more paper - can actually tell us something about reality.
Now, what space ultimately is - I should confess, I think most physicists believe - we don't yet know.
I started out as a physicist; however, I am what I have become. I have evolved, with the help of many colleagues in the international scientific community, into an interdisciplinary scientist.
Rush Holt would be a fine senator. He's an actual physicist, which is neat. He cares very strongly about global warming, which is probably the single most pressing issue of our era.
We should note that this latter type of shift was successfully amplified to a considerable extent by Russian physicists using the intense light of a ruby laser whose wavelength is close to that of a transition of the potassium atom.
Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics quite right.
My mom is an experimental chemist and physicist, so she is a cut-and-dried, nuts-and-bolts kind of woman, and my dad is a theoretical chemist, so we were definitely raised with his philosophical point of view: imaginary numbers and dimensions beyond our own. That's the kind of thing we would talk about.
