WEIRD SCIENCE Last week it was revealed that a middle school science textbook used a photo of singer Linda Ronstadt to illustrate a silicon crystal doped with an arsenic impurity. For those who may have failed science, this was a mistake, a simple production error. But a new study from North Carolina State has found hundreds of flaws in more than a dozen texts. Hydrogen appears twice on a periodic table and is described as a nonmetal and an alkali metal. In another book, sound travels faster through warm air on page 422; 12 pages later, it's swifter...
...gems go, it wasn't much, just a dustlike grain of zircon. But the tiny crystal put a gleam in scientific eyes last week. Some 400 million years older than any previously discovered terrestrial rock, it could rewrite Earth's history--upsetting the timetable for the appearance of oceans and continents, challenging ideas about the formation of the moon and, most important, pushing back by several hundred million years the genesis of life...
...indeed the case, Earth's oceans and crust appeared only 200 million to 300 million years after its formation, when the planet was still being bombarded by large objects from space. One Mars-size chunk, by that calculation, would have slammed into Earth only 50 million years before the crystal formed, ejecting enough material to create the moon. Says University of Wisconsin (Madison) geologist John Valley: "Perhaps the moon formed earlier than we thought, or by a different process...

...ruling by the U.S. Supreme Court to stop the recount of votes in Florida [PERSON OF THE YEAR, Dec. 25-Jan. 1], thereby awarding the presidency to George W. Bush, made one thing crystal clear: the Land of Liberty now has a government of the lawyers, by the lawyers and for the lawyers. What's next? In lawyers we trust?
