Can you imagine getting into the brain ofSheldon Cooper for a day? Or put yourself in Einstein's shoes for a while? Or Schrödinger's glasses, Dirac's costume, Planck's or Curie's gown ...? Yes, they all have something in common, they are all physical. And I can dare to go further: they also have something in common with you, dear reader; Yes, you, although you do not trust yourself, you are also a physicist. Do not you shrink when you're cold? Do not you click to open a can? Do not you blow to blow out a candle? Physics nosrodea, is everywhere, because we are physical and, even when we do not realize, you use it continuously, more than you imagine.
