...proton (present in the nuclei of all atoms), except that its electric charge is negative instead of positive. There may be (but probably are not) places in the universe where antiprotons can exist permanently, but on earth they are short-lived. As soon as one of them touches the nucleus of an ordinary atom, it is annihilated. Both its own matter and the matter of a proton or neutron in the nucleus turn into a flash of energy...
...wheel-like star tells what happens when one of the alien particles is annihilated. The antiproton (P¯ ) enters from the left. It is moving fast at first, but gradually slows down and merges with the nucleus of some unfortunate atom. There it combines with a proton or neutron, and both particles vanish, turning into 1,876 million electron volts of energy. The resulting explosion-extremely violent on the atomic scale-drives off fast-moving fragments that trace the lines of the star...
Some of the lines (1, 4 and 6) were traced by protons. The rest were made by pi mesons: short-lived particles that emerge when a nucleus is disrupted. There must have been neutrons too, but since they have no electric charges, they do not leave tracks in photographic film...
Flint's current No. 1 campaign is culture. The city is building housing projects, new churches, school buildings and a huge $5,000,000 civic center. In addition the Flint Junior College is expanding to become the nucleus of the new Flint campus of the University of Michigan, which will open next September. One of its main structures: the Harlow H. Curtice Academic Building. Flint's adult education program has an enrollment of 40,000 people, who study everything from classical languages to the fine art of tying trout flies. The Flint Community Music Association comprises 42 independent...
...months ago, Iraq's Premier Nuri es-Said had brought the wrath of Egypt's Premier Nasser on his head for joining Turkey to form the nucleus of the new organization. Now Nuri tried to reassure Nasser. Iraq, he said, "will not hesitate to use her resources for the assistance of any Arab state subjected to Israeli aggression." Macmillan seized his chance to argue that Communist frustration in Europe and Asia had forced the Reds to seek out new areas for expansion. Egypt's deal for Communist arms was the result, and, considering the situation, he could...
