...allow an economic gap, a sort of division, to grow up." Leaks & Bleats. The flap was the result of Macmillan's taking his informal clubman's manner to Washington, a city where today's club conversation can become tomorrow's headline.

...interiors of the stars are convenient test tubes for observing what happens at very high temperatures. Stars need no magnetic bottle; their gases are held together by their own gravitation. Earth-side gravitation is too feeble for this, so Spitzer's main job is to devise a leakproof magnetic bottle that can pinch-hit for the gravitation of the brighter stars...
Tricky Balance. Leakproof magnetic bottles, Physicist Teller pointed out, are not easy to construct. The magnetism must be just strong enough to confine the ionized gases at the right density and temperature, and keep them confined long enough for a reaction to take place. The reaction would release energy and raise the temperature, so the magnetic field must grow stronger when necessary to keep things in balance. Power must be drawn out of the system without disturbing its tricky balance...
...dominating concern for tiptoed entrances and exits, the emphasis on leakproof caskets, and the display of the physical remains artfully improved by cosmetics and specially tailored casket apparel, represent essentially a reversal of Christian belief and its candid committal of the material body to ashes and dust...
