Feynman weekphysicswould-be So far as we know, all the fundamental laws of physics, like Newton's equations, are reversible. Richard P. Feynman physicsfundamentalslaw [Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope you can accept nature as She is - absurd. Richard P. Feynman common-senseviewsreligion Doubt is clearly a value in science. It is important to doubt and that the doubt is not a fearful thing, but a thing of great value. Richard P. Feynman fearfulimportantdoubt You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird...
