the time the birds had made 26 flights, the enthusiasm had become ennui. The postponements of attempts to launch the Challenger before January 28 drew journalistic jibes. On the eve of NASA's disastrous decision to fire the Challenger into space despite very cold weather at Cape Kennedy, Dan Rather opened the "CBS Eve- ning News" with a remark about "yet another costly, red-faces-all-around space shuttle launch delay."
Although specialized magazines (e.g., Science, Aviation...
making the punish- ment for committing such misdeeds more serious. Last year, the Depart- ment of Justice prosecuted Samuel L. Morison, a Navy Department intelli- gence analyst, for selling secret satellite photos of a Soviet shipyard to the British magazine, Jane's Defence Weekly. Morison was convicted of violat- ing the Espionage.Act-of 1917-a rarely invoked law that had previously been used to prosecute people for aiding a foreign enemy, but not for leaking to the Western press.

begging, they walked "two two, barefooted, dressed in wool, possessing nothing, but holding all in common after the example of the Apostles." The Roman Catholic Church despised them, says Lemer, both for their "ostentatious poverty" (which put highhing orders in a bad light) and their unre-strained lay preaching. Waldo tried to gain Rome's blessing, but instead was excommunicated around 1182. By 1184, Pope Lucius I11 had declared all Waldensians heretics.

grasped directly, in an experience Edwards called "grace." What was the key to this heightened state? The Scriptures and nature. Even as a child, Edwards doubted the tradi-
tional Protestant doctrine of "predestinationw-the notion that some souls are born to salvation, some to damnation. age 18, he was convinced that anyone who read the Bible and studied nature could receive God's glory-provided that he had achieved "grace." For Edwards, that moment was u...

humid air occur. If the updrafts are powerful enough to soar into the cold troposphere, five to 11miles up, tall, anvil-headed cumulonimbus clouds form. As the tropospheric wind rises, temperatures fall, and the high- vaulted clouds become electrically charged-negative on top and positive on the bottom. In reaction,-the underlying sea or land surface takes on a negative charge. As the electrical attraction between ground and cloud grows (as high as 100 million v...
the Middle Preclassic period (1250 B.C. to ~~Q.B.c.),
trade had become sophisticated, with Mayan com- munities exchanging obsidian glassware and jade throughout Guatemala.
The Late Preclassic period (450 B.C. to A.D. 300) saw the emergence of religious and political conventions typical of Classic Maya civilization. In 1980, working near Cuello, Belize, Harnrnond discovered that Mayan vil-lagers had replaced their small courtyard with a large ceremonial site around 450 B.C. To commemorate that...

depths. To stay above 800-foot depths where it would be crushed, the nautilus pumps water in and out of its shell chambers, like ballast in a submarine, to regulate its buoyancy. Feeding at night, the nautilus relies mainly on smell. Its primitive eyes are lensless, like a pinhole camera. At nine inches it can barely discern what a human can see at 165 yards.

the National Science Foundation. The report warned that the genetic pool of existing crops
might become too shallow, leaving plants vulnerable to disease or environ- mental shock. Fanners were urged to shift away from crops that need large amounts of water and soil nutrients, or that cannot survive in a broad range of temperatures and soil conditions.
Several plants native to the United States offer alternatives. The buf- falo gourd, a relative of the squash and pumpkin family, is one. Indigenous...
releasing water very sparingly, the TVA dams had created a "eutrophication" problem: In still waters, micro-organisms absorb oxygen needed fish, which either die or move away. The Bonneville Power Administration will spend up to $30 million to fit screens on its 15dams to keep migrating salmon from getting hacked up by the blades of the 60-foot turbines.
Most U.S. dams were designed and built long before the 1970 National Environmental Policy Act, which requires an ecological "impact"...

ARTS & LETTERS
Born in Moscow in 1931, Semyonov started out writing for Ogonyok, a newsweekly. In 1963, after a string of modest successes with fiction, he became a sensation with the publication of Petrouka 38, a thriller that described Soviet police methods in detail.
Semyonov's -next eight novels featured his most popular character, Maxim Stirlitz. He is the Soviet James Bond: athletic (a tennis champion), sensitive, educated (he can discuss Pascal and Kant), and courageously...
