Both men called for reducing the number of deer to limit the havoc they're wreaking on the Wisconsin environment. There are about 1.4 million deer in Wisconsin, with density in northern Wisconsin forests between 20 and 30 deer per square mile. The ideal, in terms of their impact on plant life, would be 10 to 12 per square mile. Over the past few years, it has become clearer that many galaxies, perhaps the majority, formed as small gas clouds, then merged into larger and larger galaxies as time went on. But astronomers haven't yet proven that this is the main way it happens.
Circumstantial evidence favors merging, but deep space is a gas-clouded kind of place.
You stand there and stare a little more closely, and squint, and try to tell whether that thing off in the distance is a barn or a truck. Amit Lal , an electrical and computer engineer, has created a new class of medical cutting tools etched from wafers of silicon, using some of the same lithography techniques behind integrated circuits. His silicon blades are up to 10 times as sharp as the advanced medical tools made from metal. The site, a joint venture between the Robert Wood Johnson Project , a campaign to end student binge drinking, and DANEnet, provides a comprehensive database of upcoming events. Rob Adsit , the campus-based RWJ project coordinator, says the site fills a void for students who are looking for something to do.
