A moving body whose motion was not retarded by any resisting force would continue to move to all eternity. Hermann von Helmholtz

The formation of scales and of the web of harmony is a product of artistic invention, and is in no way given by the natural structure or by the natural behaviour of our hearing, as used to be generally maintained hitherto. Hermann von Helmholtz

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

Heat can also be produced by the impact of imperfectly elastic bodies as well as by friction. This is the case, for instance, when we produce fire by striking flint against steel, or when an iron bar is worked for some time by powerful blows of the hammer Hermann von Helmholtz

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 Helmholtz

All that science can achieve is a perfect knowledge and a perfect understanding of the action of natural and moral forces. Hermann von Helmholtz

Windmills, which are used in the great plains of Holland and North Germany to supply the want of falling water, afford another instance of the action of velocity. The sails are driven by air in motion - by wind. Hermann von Helmholtz

Just as a physicist has to examine the telescope and galvanometer with which he is working; has to get a clear conception of what he can attain with them, and how they may deceive him; so, too, it seemed to me necessary to investigate. Hermann von Helmholtz

Black is real sensation, even if it is produced by entire absence of light. The sensation of black is distinctly different from the lack of all sensations. Hermann von Helmholtz

All change in nature amounts to this, that force can change its form and locality, without its quantity being changed. Hermann von Helmholtz
