Despite admitting that flaws exist in Samuelson's book, Eckstein had some words of praise for the text. "In terms of writing quality and a certain sparkle, it was in its own way unique," he said. He added, however, that he realized that sparkle evoked a "Two-edged reaction" among some Harvard students...
...were made up of approximately 7 per cent blacks, the Class of 1980 had a black population of about 8 per cent, black enrollmentdeclined to 7 per cent for the Class of 1981 and went up again to about 8 per cent for the Class of 1982. Similar consistencies exist in the figures for Hispanics and Asian-Americans which both hover between 2 and 3 per cent over the last five years...
...there can be no doubt that the star athlete can and does exist at Harvard. They've never manufactured jocks at Cambridge, and they're not about to start now. "Athletic scholarship" is not in the vocabulary, "first round draft pick" a rare species...
...late 1930s, on the eve of World War II, Oppenheimer published two landmark papers in the journal Physical Review. The first, in collaboration with a graduate student named George Volkoff, argued that neutron stars could in fact exist. They would have a diameter of about 10 km (6 miles) and weigh about 10 million tons per cu. cm. In the second paper, innocuously titled "On Continued Gravitational Contraction," Oppenheimer and another student, Hartland Snyder, contended that if the dying star was massive enough, nothing in Einstein's theory stood in the way of the ultimate compression?the formation...
Astronomers so far have been unable to find the necessary mass in the observable galaxies and gas clouds, but if black holes do exist in the numbers that some scientists believe, they would provide additional gravitational braking and reverse the expansion. If that is the case, the universe?like a giant, collapsing star will eventually begin falling back upon itself...
