Havana weltered in a heavy crime wave. So far this year there had been some 48 murders, practically all of them black-sedan-and-submachine-gun jobs in South Chicago style. Most seemed to be political, the vengeance of hot-headed young terrorists exploding against officials of the Batista regime now that the dictator was out, the war over and the country economically upset. When assassins shot an ex-police chief as he read the paper one evening on his front porch, they left behind the sign of the Union of Revolutionaries: "Justice comes late, but it comes...
Infra-red rays pierce some clouds ; so Dr. Walter Baade of Mt. Wilson, Calif, photographed the proper part of the sky with infra-red light. His plate showed a dim, ghostly shape (see cut). Drs. Stebbins and Whitford, encouraged, used infra-red light of still longer wave length. They attached a photoelectric cell and an infra-red filter to the Mt. Wilson 60-inch telescope and swept it back & forth across the area where the nucleus ought to be. Their calculations showed a strong elliptical bulge. The happy astronomers did not claim that this was the Milky...

Some unreasonable devilment urges you to start the compressibility processes which in a few seconds can wrench all control away from you and plunge the ship into wild, tremendous vibrations...
...next Council is not to be neutralized by a wave of non-confidence growing out of its continued denial of the democratic process, it must scrap the present plan of nomination-appointment and substitute a system of free election of representatives. It is generally conceded that the Houses provide a more cohesive group of elective units that do the classes, thus each of the Houses and Dudley should be alotted two representatives, to be chosen by open election. The incoming Sophomore class would be represented by six men, to be chosen from the Yard on the same plan...
