There is a kind, I might almost say, of artistic satisfaction, when we are able to survey the enormous wealth of Nature as a… — Hermann von Helmholtz Copy Share Image
The law in question asserts, that the quantity of force which can be brought into action in the whole of Nature is unchangeable, and… — Hermann von Helmholtz Copy Share Image
What we see is the solution to a computational problem, our brains compute the most likely causes from the photon absorptions within our eyes. — Hermann von Helmholtz Copy Share Image
A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep… — Hermann von Helmholtz Copy Share Image
I think the facts leave no doubt that the very mightiest among the chemical forces are of electric origin. The atoms cling to their… — Hermann von Helmholtz Copy Share Image
A moving body whose motion was not retarded by any resisting force would continue to move to all eternity. — Hermann von Helmholtz Copy Share Image
But heat can also be produced by the friction of liquids, in which there could be no question of changes in structure, or of… — Hermann von Helmholtz Copy Share Image
