|
Laws themselves, after all, exist even when they have not yet been discovered, as in the case of Archimedes' principle before Archimedes, Snell's law before Snell, and Newton's before Newton. |
|
This view implies that Archimedes was less an engineer trying to manipulate the physical world than a pure mathematician interested only in abstract concepts. |
|
The bulk density of the sintered dense samples was measured by the Archimedes principle using a standard densimeter. |
|
This idea came to me from the discovery of a treatise on the equidomoide, forms studied by Archimedes and then between 1867 and 1875 by Leopold Hugo, nephew of Victor, who gave it its name. |
|
It was apparently Archimedes, in his bathtub, which devised a means of determining the amount of alloyed metals, although it seems probable that his principle was known long before the advent of Greek science. |
