EARLY this year, the editors of this magazine initiated an investigation into atomic medicine as one of the first and perhaps most valuable by-products of the two-billion-dollar Manhattan Project. We knew that man's ills and pains are not popular unless they are personal.

THE average human head supports 130,000 hairs. Every time the world washes its head, approximately 286,000,000,000,000 hairs are scrubbed. But only recently has anyone made a moving picture of a single hair being washed. Those pictures indicate that the most efficient shampoo is an alkyl-sulphate solution.

The Editors
Like every big publication, Popular Science Monthly has been hard hit by the paper shortage. We are forced for awhile to take, and use in part of each issue, a quality of paper way below our standard. We don’t like to see fine illustrations come out on the page looking like soft coal on a tablecloth.

CARL DREHER
IN 1912 Dr. Georg von Hevesy, a young Danish scientist, was at Rutherford’s laboratory in London, experimenting with radiation and radioactive atoms. Hevesy was a bachelor and lived at a boarding house, where the meals aroused his suspicions.

THERE is no royal road to therapy. Optimistic expectations that recent developments in atomic technology will lead to a swift and easy solution of the more intractable problems of medicine are doomed to disappointment. Radioactive isotopes and the new forms of radiation are extremely important, but there have been important developments before and people still get sick and die—although they do live a lot longer, on the average, than they used to.

Mud THAT'S WORTH MONEY
"MINED" IN A DRY LAKE BED, IT LUBRICATES BITS THAT DRILL FOR ADDITIONAL SOURCES OF OIL

THE bearded prospectors who shuffled painfully across Rogers Dry Lake in the Mojave Desert years ago were heading toward gold in the west. But at every searing step they were literally walking on riches. Not gold but—MUD. The rigs that drill into the earth seeking oil must be lubricated to keep the bit cool, to float off the rock cuttings the bit gouges away (PSM, Dec. 31, p. 20), to “plaster” the shaft so it won’t cave in, and to hold down gas or oil that might “blow out” the well by pressure.

PUBLISHER Godfrey Hammond likes to define editing as “the big dream plus infinite patience with the little pieces.” Certainly any publication, whether crossroads weekly or million-copy magazine, has to have a big idea. And it has to express that idea with a mosaic of small pieces: the uncounted combinations of the alphabet; the pieces of type; the thousands of dots of metal that transfer a photograph to the printed page; the even tinier dots of ink that make color printing possible.
