...numbers ? Consider, for example, the molecules of water in this glass. According to Sir William Thomson, if a drop of water were magnified to the size of the earth, it would appear coarser-grained than a heap of small shot, and finer-grained than a heap of cricket-balls....

...question than that of any other fact of physical science. The atoms are infinitesimally small, so small that, if a drop of water were magnified to the size of the earth, the constituent atoms would be about the size of footballs. Perhaps a more striking illustration is that,...

...apart in a gas. Another method of showing the probable size of molecu-les is the following: Suppose a drop of water were magnified to the size of the earth, the molecules would be between the size of a cherry and that of a cricket ball. And now we are brought to the newer...

...Molecules are so small that it is difficult to realize their minute size. Atomic scientists tell us that if a drop of water were magnified to the size of the earth (8,000 miles in diameter) its molecules would be the size of baseballs. Also, they would be in continuous...
