...behaviour we can single them out for measurement, so that Sir William Thomson can tell us that if the drop of water were magnified to the size of the earth, the constituent atoms would be larger than peas, but not so large as billiard-balls. If we do not see such...

...vibrations ; for, as Sir Wm. Thomson has calculated the atoms in a drop of water are so small, that if the drop of water were magnified to the size of the earth, the atoms would then be seen not larger than cricket-balls and not smaller than shot. It must be clearly...

...of their size we must betake ourselves to a scheme of threefold magnification. Lord Kelvin has shown that if a drop of water were magnified to the size of the earth the molecules of water would be of a size intermediate between that of a cricketball and of a marble. Now each molecule...

...concludes — Thomson and Tait, Natural Philosophy, voL i. part 2, App. F, 1883, and Nature, July 1883 — that if a drop of water were magnified to the size of the earth, the molecules or granules would each occupy spaces greater than those filled by small shot, less than those occupied...

...millionth of an inch, or less than the iOOO millionth. These dimensions he has illustrated thus — " If a drop of water were magnified to the size of the earth, the atoms of which it is composed would appear larger than small shot, but they would not be as large as...

...interesting speculations, founded upon physical phenomena, respecting the probable size of the atom, viz., ' that if a drop of water were magnified to the size of the earth, the constituent atoms would be larger than small shot, but smaller than cricket balls.' Again, Helmhollz...

...microscope. Some idea of their extreme smallness may be gathered from Sir William Thomson's estimate. He says that if a drop of water were magnified to the size of the earth, its molecules, so magnified, would be about as large as base-balls. Common Properties of Matter. —...
