There’s a line often attributed to Richard Feynman that says, “just as birds don’t need to study aerodynamics to fly, a scientist doesn’t need to study philosophy of science.”
Many people link science to what is measurable and observable. Anything outside that area gets lumped into philosophy (metaphysics, beyond physics). So topics like God, love, ethics are usually seen as outside the scientific scope.
The question is, does science only talk about, or should it only talk about, what is observable and measurable? Is that a useful practice or harmful to science?
Are there examples that support each position?
Are physicists better scientists if they study philosophy, or is that a waste of time?
