There are theoretical physicists who imagine, deduce, and guess at new laws, but do not experiment; and then there are experimental physicists who experiment, imagine, deduce, and guess.

Physicists like to think that all you have to do is say, these are the conditions, now what happens next?

For those who want some proof that physicists are human, the proof is in the idiocy of all the different units which they use for measuring energy.
