Physicists probing within the atom toward the ultimate constitution of matter already had their hands full with positive and negative electrons, neutrons (uncharged particles), protons (nuclei of hydrogen atoms), deuterons (nuclei of doubleweight hydrogen), tritons (nuclei of tripleweight hydrogen), alpha particles (nuclei of helium), and the theoretical but necessary neutrino (little neutron...
Research on the atom has attracted some of the most brilliant minds of contemporary science, and atomic history is strewn with the names of Nobel Prizewinners. Aged Sir J. J. Thomson, who discovered the electron, is a Nobelman; so is Niels Bohr of Denmark and so was the late Lord Rutherford of England, who formulated atomic structure. Their atom was, and still is, a nucleus surrounded by electrons. But in the 1920's, with the powerful searchlight of relativity illuminating the atomic field, it became apparent that the picture of the electron as a simple particle of negative electricity...
...poise which she maintained even when the cook got drunk and had to be locked in the mop closet, or the downstairs maid tried to touch the family for three dollars to pay her bookmaker. Papa Pemberton (Etienne Girardot) might have received the Nobel Prize for breaking down the atom if Junior had not objected that the award would overshadow his fame as a child prodigy...
...ultracentrifuge - a machine which separates heavy molecules from light ones, inferentially measuring their molecular weights, by whirling them at enormous speeds. In this ultracentrifuge the molecular weight of the Stanley crystals was found to be about 17,000,000 units (17,000,000 times as heavy as a hydrogen atom...
...Only the hydrogen atom contains no neutrons...
