"Perpetual motion" Quotes from Famous Books
 ... seems at present to be agitating as many pseudo-scientific minds as did that of perpetual motion not many years ago, or the philosopher's stone at a more remote period. It possesses perhaps a still stronger attraction in the danger connected with the experiments—the source, we suppose, of the eagerness shown by Professor Wise and ...

... was half Italian, (being glad of coming out of little Barbary, and a universal tippling-house,) I would take no notice of it; being well satisfied, that the mathematicians of our times can no where find out the perpetual motion so well as here, where the goblets of Germans are an evident demonstration of its possibility—they think they cannot make good cheer, nor permit friendship or fraternity, as they call it, with any, without giving the seal brimful of ...

... Dr Thomas Young demonstrated that certain curved surfaces suspended by a thread moved into and not away from a horizontal current of air, but the demonstration, which approaches perilously near to perpetual motion if the current be truly horizontal, has never been successfully repeated, so that there is more than a suspicion that Young's air-current was NOT horizontal. Others had made and were making experiments on the resistance offered to the air by flat surfaces, ...
