...machines have come a long way from the first karts pieced together from steel tubing and lawnmower engines in late 1950s California. Sure, karts typically lack gears, and there's no suspension to speak of. But there's often a push-button starter, a hydraulic disk brake, and a tiny onboard computer that measures everything from average speed to G-force. In the cadet class for the youngest competitive drivers like Nelson, the karts' 60-cc engines clock speeds of around 50 m.p.h. (80 km/h). The junior classes - open to racers from around 12 - have...
...which uses infrared-sensitive cameras to peer through the shroud of dust that surrounds newly forming planetary systems to see what's going on inside. In one such system, known as IRAS 4B, about 1,000 light-years from Earth, astronomers from the University of Rochester have detected a disk-shaped knot of material that will one day emerge as a suite of planets orbiting a young star...
...onto that disk, a rain of ice crystals is falling, slamming into the disk at supersonic speeds and vaporizing to form a cloud containing five times the water in Earth's oceans. What the astronomers are convinced will happen next is that the water will re-freeze into ice particles and eventually form comets - which in turn will crash down onto whatever planets they find, forming oceans that the future scientists of these worlds will someday be scratching their heads over...
...heart of 37signals, named for an attempt to find signs of intelligent life in space, are four pieces of software that help business teams manage projects (see below). Subscribing to the Web-based software costs $12 to $149 a month, depending on the amount of disk space and the number of features you use. The thousands of paying users--Fried won't say exactly how many--provide 37signals with a steady revenue stream. The subscription model minimizes the up-front cost for small businesses and makes software spending more predictable for firms worried about cash flow. The monthly fees include...
