"If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them"
About this Quote
The intent is double-edged. On one side, it’s a defense of quantum mechanics against the demand that it behave like classical physics in a lab coat. On the other, it’s a shot across the bow at the overconfident explainer: anyone who speaks about the quantum world with too much certainty is probably smuggling in a comforting metaphor. “The first thing” is a subtle jab at the premise that understanding equals simplification. In Bohr’s Copenhagen universe, understanding begins when you accept that observation and description are entangled with the phenomenon itself, that you don’t get a crisp picture without paying for it in paradox.
Context matters: Bohr spent years sparring with Einstein and others who hated the theory’s indeterminacy. This quip is rhetoric as philosophy, insisting that emotional vertigo is not a side effect but a diagnostic tool. If you’re not a bit shaken, you’re still doing classical physics cosplay.
