...main trends of H-bomb development, however, are clear to all. An early step was to force the temperature of the fission detonator (atom bomb) as high as possible. One way to do this is to make the fission reaction more efficient. The early bombs "burned" only a fraction of their fissionable material. As they were improved, they burned more of it and reached higher temperatures. The improved bombs, even though not designed with hydrogen bombs in mind, were therefore more effective as detonators...
...Salk's laboratories could not produce more than a fraction of the hundreds of gallons of vaccine needed for such a massive trial. So it is being made according to his specifications on a nonprofit basis by five pharmaceutical houses-Parke, Davis & Co. in Detroit. Pitman-Moore and Eli Lilly & Co. in Indianapolis, Wyeth Inc. in Philadelphia, the Cutter Laboratories in Berkeley, Calif. For all of them, the indispensable raw material is the monkey, and the procedure is much the same. For example...

We see that, although a large fraction of the world's population is starving, all of humanity can, in principle, be nourished adequately. We see that, although world populations are increasing rapidly, those populations can, in principle, be stabilized . . . But it is equally clear that the achievement of this condition will require the application of intelligence, imagination, courage, unselfish help, planning and prodigious effort . . .

...Soviet Union's billion-dollar trade offer, if it works out, would involve a tripling of Russia's non-Communist trade. Few Britons believe that this is possible: even a fraction of that amount would involve a drastic change in the world's trading relationship. Yet, undeniably, the vast Soviet offer had raised all Europe's hopes. It made certain that East-West trade will be one of the vital issues...
Every U.S. traveler to Canada nowadays is soon made aware of one painful fact: to Canadians a U.S. dollar is no longer worth 100 cents. This week the exchange rate climbed a notch higher. Canada's dollar edged upward a fraction each day until it was selling in Wall Street for 103.4 U.S. cents, the highest price in more than a year...
