...education bill is very different from the medicare bill or a public works measure. It produces no dramatic, visible results, like the opening of a new highway or a successful orbital flight. It does not directly benefit any broad segment of the population except students, and students do not vote. It has no powerful and well-oiled financial interests behind it--the professional education lobby, such as it is, remains fragmented and ineffectual...
...most respected college presidents in the nation, Morehouse has improved the quality of its teaching, expanded its facilities, and sent more and more graduates on to higher training. But the problem that Washington did not come to grips with still remains: the intellectual and technical proficiency of a segment of the Negro community will not guarantee a better life for the majority. Education, to many Negroes just as to whites, represents an exemption from the plight of the masses rather than a responsibility to improve that plight...
...Hofmann patiently built a copy of the smaller fragment. After he had stuck 13 of the acids together, he joined his synthetic segment to the 104-acid remainder of natural ribonuclease. The reconstituted enzyme proved to have 70% of the activity of the natural substance. Apparently the seven amino acids, Nos. 14 to 20, that had been left out are like the chip collector on a lathe-useful but not essential...
...Hofmann then synthesized an eleven-acid segment and joined it with the rest of the enzyme. This substance proved wholly inert. Apparently amino acids Nos. 12 and 13 that he had just eliminated are at the "active site" of the enzyme, like the cutting tool of a lathe...
...series of digits: 1:02, 2:04, 3:09, 4:14, 5:19, 6:24, 7:29, 8:31. These were the times at which jaunty Jim Beatty, 28, the best U.S. distance runner and holder of the world indoor record for the mile, was to complete each segment of a precisely planned assault on the indoor two-mile record (8 min. 34.4 sec.) held by New Zealand's Murray Halberg...
