On the linked page http://www-math.mit.edu/%7Edhu/Striderweb/striderw eb.html Someone has blotted out the intimate details of the waterstriders mating ritual. Is he seriously worried about offending someone, or is he worried about hosting a porn site? Who says political correctness has gone wrong... This is just pathetic.

Chan designed and built a mechanical water strider. Robostrider is made out of a 7-Up can, stainless steel wire legs and an elastic band coupled to a pulley to power its middle legs. Light enough not to break through the water surface, it travels half a body length per stroke. Like its natural counterpart, Robostrider's principal means of transferring momentum is in the form of vortices shed by the rowing action.

Researchers at MIT have solved the mystery of how water striders propel themselves across water surfaces I have an old Biology book (1994) that explains why water striders are able to stay afloat on top of the water (due to the interaction amoungst water molecules - van der Walls forces) as well as how they can move along the surface. I think the author should have been a little more careful in his wording of this article.

Yet, the US News & World Report ranking of colleges [usnews.com] shows statistics in which "minorities" comprise more than 50% of the student population.

It seems to me, a group is not a "minority" if it constitutes 98-99% of the population at an institution (especially in the case of the historically black colleges).

The minority being referred to in those articles would be the portion of the US population as a whole (which was 75.1% white in 2000 according to the US Census Bureau [census.gov]). So an institution with 99% minorities would mean 99% of the students belong to the "not white" ethnic group, which is a country-wide minority.

Of course, that link also shows the US as 50.9% female, leaving /. with, more than likely, a heavily minority membership!
