The principle of least action - one of my favourites

Nature is lazy to such a degree that it will even often stop you from doing whatever you are doing so that it can stop doing stuff. For example, Lenz’ Law

The current induced in a circuit due to a change in a magnetic field is directed to oppose the change in flux and to exert a mechanical force which opposes the motion.

So basically; if you start playing around with magnets and circuits, nature will induce currents in such a way to stop you. That is next level lazy.

Hey what book is that from?
