Although mechanical energy is indestructible, there is a universal tendency to its dissipation, which produces throughout the system a gradual augmentation and diffusion of heat, cessation of motion and exhaustion of the potential energy of the material UniverseCollection: Energy
I have not the smallest molecule of faith in aerial navigation other than ballooning, or of the expectation of good results from any of the trials we heard of. So you will understand that I would not care to be a member of the Aeronautical Society.Collection: Future
I have no satisfaction in formulas unless I feel their numerical magnitude.Collection: Satisfaction

Vortices of pure energy can exist and, if my theories are right, can compose the bodily form of an intelligent species.Collection: Intelligent
At what time does the dissipation of energy begin?Collection: Time
