  • 1:25 He's talking about Newton's law of motion, but seemingly doesn't know it. We know why, it has to do with resultant force being zero, then it either stands still or moves at a constant pace unless a new force starts working on them (though keep in my mind that in practice there are factors such as wind etc, depending on the example).

  • @VikTheBrik Well in fact Newton's laws are AXIOMS, i.e. left without proof (and indeed a statmenent such as "The velocity of a body remains constant unless the body is acted upon by an external force" (Axiom 1) cannot be proven mathematically ...)

  • Hey everyone below me, i got an idea! Lets all waste our time arguing with each other on a video sharing website. Maybe that will solve the problems in the world.

  • @64wonderboy . . . Rabble ! Rabble ! Rabble !

  • Brilliant. Feynman was the greatest physicist that ever lived... What a clear mind! I recommend everyone to watch many of his lectures.

  • @VikTheBrik what he is trying to say is that we don't know why things will not change their motion unless acted upon by a force, or even a step further back still, why forces exist

  • really creative and  inspiration thoughts ........

  • Yes, but one thing about knowing the name of something is that it can convince a lot of other people that you actually know something about the thing. And if you don't know the name, then even if you know other things about the thing people might not think you know much about it.

    I'm talking about people who aren't very bright, of course, but they seem to be around a lot, so it's usually good to know the names of things just for smart-soundingness.

  • Well my dad taught me how to shoot the bird and eat it. I find that to be far more useful.
