...separating U-235 rises with the fourth power of the speed of the rotor, i.e., doubling the speed would multiply the efficiency by 16. Better materials and construction methods have recently increased the speed to at least 40,000 r.p.m. Up-to-date centrifuges spin in a near vacuum, and they have complicated heating devices to make the gas circulate inside them in a way that multiplies their efficiency...
Rarely have a nation's newspapers been riper for infiltration. The Japanese press, huge (103 dailies with 35 million circulation) and savagely competitive, is a vacuum sustaining no cause but a steady antagonism to all authority. It is largely owned by business-minded publishers so remote from their editorial floors that the congress flourished almost by default...
...Solid state" is an inclusive term that covers electronic and related devices whose action takes place in solid materials, usually crystals, instead of in the vacuum of electronic tubes. In many cases the action is similar. The transistor, the most famous solid-state device, is closely analogous to the familiar tubes in radios. Chief difference is that the electrons that make it work do not move across a pumped-out vacuum. Instead, they move through the tiny clear channels between the lined-up atoms of a germanium or silicon crystal, which provide a sort of readymade vacuum...
...MacMurray as a widower trying to raise his three sons, and trying, as well, to be another ratings-wealthy Bachelor Father. Like all situation comedies, this one sets its sights low and aims for modest objectives, reaching them with a professionalism as smooth as glass, blown to enclose a vacuum. In the first episode, both MacMurray and his devastatingly cute ten-year-old son were chastely chased by women of appropriate ages...
...have become so accustomed to reliance upon nuclear deterrence, disguised as "security," that its rejection creates a vacuum that appears equally frightening at first glance. Conflicts among nations exist and will continue to exist, and we must consider how to keep alive our basic values and defend our tradition of liberty in the absence of the self-defeating policy of deterrence. Today the choice before thinking Americans who are concerned about the future of the nation and of mankind is not total surrender versus total annihilation. This idea is either a deliberate invention to support the massive retaliation doctrine...
