...keep the coils from blowing up, Kapitza cooled them with liquid helium (four degrees or less above absolute zero). He designed his own helium liquefier...
...standard method involves liquid hydrogen, which is unstable and highly explosive. Kapitza's method not only did away with liquid hydrogen, but. cut the cost of making a quart from $50 to $5, the time from 24 hours to two hours or less. In the neighborhood of absolute zero, ordinary lubricants freeze hard as iron and Kapitza's problem was to find a lubricant for his compressor. He solved the problem by allowing a little helium vapor to squeeze through the piston clearance, so that the helium itself did the lubricating...
From the Klondike the Yukon River brawls across the U. S. border into desolate interior Alaska at the town of Eagle.* Here is tough country.

Few sourdoughs and no chechakhos live on these rolling tundras, where the ground is frozen several hundred feet down-country in which Chechakho Jack London starved and froze, seeking gold and finding stories...

First Oklahoma alumnus to hold the office (salary: $10,000), 41 -year-old Joseph Brandt, a Lutheran, will succeed BaptistBible-collecting William Bennett Bizzell next August.

Actually they are pearls-and, as pearls go, huge. Their value as jewels is zero, but they are precious to science. They are fossil pearls...
