...rocks and of other light gases escaping from the moon's interior or contributed by the vaporization of meteors hitting the surface. Elsmore figures that if the moon's atmosphere is half permanent (heavy) and half temporary (light), it will be something like one five-trillionth (2 x 10¯¹³) as dense as the earth's atmosphere...
They did not create much of it-only about 50 atoms or one billion-trillionth of an ounce. "Hardly a commercial quantity," said Chemist Fields. Asked why he and his friends went to such trouble, he said with a happy smile: "Well, discovery of a new element is considered a big thing in some circles...
...seemed that the atom-already split, measured, analyzed, and prodded by great machines-had few secrets left. Scientists were almost agreed that the atomic nucleus (one-trillionth the size of an atom) is a solid sphere. Now Stanford University Physicist Robert Hofstadter and his assistants have examined the nucleus and found more space in the atom's heart than anyone had guessed...
...woman could not talk and did not recognize her family. Into her bloodstream the doctors injected a solution containing boron, a common, stable element with an atomic weight of 10. But under neutron bombardment, boron-10 changes to an excited boron-11, which lives about one-hundredth of a trillionth of a second. In that infinitesimal fraction of time before it decays to stable lithium, it shoots out alpha particles...
