...This week, on the day of the book's publication, Albert Einstein was 60. On his birthday he hinted that he had at last developed a "unified field theory" which would link his picture of the universe with the accepted scientific view of the behavior of the atom...
...Otto Hahn, 60, of Germany's Kaiser Wilhelm Institute, and his coworker, F. Strassmann, had bombarded uranium with neutrons. In the products of bombardment they found something which seemed to be atoms of barium. This barium was the clue to something terrific. For the huge uranium atom, heaviest of the 92 standard elements, weighs 238 units.* The barium atom weighs 137 units. Since the barium could have originated only as a fragment of the big uranium atom, it was logical to suppose that the latter had cracked asunder, in two nearly equal parts. The release of atomic energy...
...Hahn calls himself a radiologist and his previous record includes discovery of several radioactive elements. Some years ago he lectured at Cornell, is remembered there as an "outstanding scientist"-also as a good lecturer, an amiable and energetic man. Last week the "fission" of the uranium atom definitely looked like a find of Nobel Prize calibre. But present German law forbids Germans to accept Nobel Prizes. Meanwhile, physicists have unofficially distributed some of the credit to Liese Meitner in Stockholm (a woman physicist) and R. Frisch of Copenhagen, who presented a fine interpretation of what happened when the uranium atom...
Since the first explosion reverberated through the world's laboratories, the fission of thorium, as well as uranium, has been demonstrated. Atom-wranglers at Columbia University have shown that, under various conditions, the fission of uranium yields krypton, strontium, iodine, xenon, tellurium as disintegration products. The flood of reports made it appear that atomic physicists are off on the biggest big-game hunt since the discovery of artificial radioactivity was announced...
...unit is approximately the weight of the hydrogen atom (or, precisely, 1/16 the weight of the oxygen atom...
