I guess there are some advantages to being relatively poor and having only a limited number of cable TV channels, because I saw what I thought was an excellent presentation today (if you like research-type things) on the Research Channel from the University of Kentucky. There is more information at

including the fact that it is on today at

Tuesday, February 19
10:00 a.m. PT (that's Pacific time in the U.S., or GMT-08:00)
4:00 p.m. PT
10:00 p.m. PT

It is almost an hour program, and apparently is online at the same time. You may be able to get it from the Web as an archive, too. Check at
