...pointed out that the old analog camcorder some friends lent us last year--roughly the size and weight of a parking meter--isn't exactly state of the art. Video cameras began to shrink more than a decade ago with the introduction of 8-mm tape in cigarette pack-size cassettes that were far smaller than the bulky VHS tapes that fit in our borrowed recorder. Quality improved in 1989 with the introduction of Hi8 film, and it caught on with some 10 million consumers, making 8 mm and Hi8 the most popular format. (The closest competition...
...before you say, "Oh, that will never work!" consider the following. Two studies out in the past two weeks show just how important it is to adopt good eating habits early in life. One study published in Circulation found that children who gain a lot of weight as youngsters develop more risk factors for heart disease as adults.

Fooling around with the arithmetic of propulsion, he calculated the energy-to-weight ratio of various fuels. Fooling around with airtight chambers, he found that a rocket could indeed fly in a vacuum, thanks to Newton's laws of action and reaction. Fooling around with basic chemistry, he learned, most important, that if he hoped to launch a missile very far, he could never do it with the poor black powder that had long been the stuff of rocketry. Instead, he would...
