I think the facts leave no doubt that the very mightiest among the chemical forces are of electric origin. The atoms cling to their electric charges, and opposite electric charges cling to each other.
Hermann von HelmholtzA metaphysical conclusion is either a false conclusion or a concealed experimental conclusion.
Hermann von HelmholtzWhat 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 HelmholtzThe total quantity of all the forces capable of work in the whole universe remains eternal and unchanged throughout all their changes. All change in nature amounts to this, that force can change its form and locality, without its quantity being changed. The universe possesses, once for all, a store of force which is not altered by any change of phenomena, can neither be increased nor diminished, and which maintains any change which takes place on it.
