Inside the stars, where the temperature may reach a "scorching" 20 million degrees centigrade, thermonuclear reactions are constantly at work changing hydrogen into helium. The University of Chicago's Dr. Otto Struve, head of the 42-man U.S. delegation, repeated a solemn prediction: in 3 billion years some stars will have burned up most of their hydrogen, leaving the helium "as 'ashes' of this stupendous nuclear transformation furnace...
Northern Visitors. Dr. Carl W. Gartlein of Cornell told the physicists how he'd taken spectrograms of auroras (northern lights) and found that some of their light comes from hydrogen ions (protons...
...radiation shot from its circular chamber. It slammed through a foot of lead, losing only half its strength. The physicists found that the beam was made up of high energy neutrons (nuclear particles with no electric charge). The neutrons were debris left over when speeding deuterons (nuclei of heavy hydrogen) hit a target inside the cyclotron...
...atomic nuclei (except those of hydrogen) contain two or more protons. These have positive charges, and so should repel each other violently. Instead, they are held together by a mysterious attraction. For a generation, physicists have wondered what the attraction...
More Speed. The Lamb & Retherford experiment acted rather like an improved microscope, revealing fine details about the hydrogen atom which earlier and coarser methods had left unsuspected. Now scientists, equipped with a new road map, may move ahead with more boldness and speed. Perhaps they will find out things that no one knows at present: what electrons and protons-and even matter itself-really...
