The Texas A&M Physics Department Physics Festival is today [5]!!! If you're in town, you should wonder over to the Mitchell Physics building, (see the picture), on University Drive. Nobel laureates will speak, there will be three showings of a physics circus, and there will be tens and possible over a hundred hands on demos to take a look at. Lately, the chemistry, mathematics, and engineering departments have gotten in on the fun, so things could get crazy! Oh, and there's almost certainly going to be exploding bottles of liquid nitrogen used to erupt water out of barrels, a perennial crowd pleaser. On the theory side of things this week, I'm working on re-calculating the line element of the Takeno transform. The transform was derived by Takeno in 1952 in an attempt to explain what happens to a rotating disc when it rotates at special relativistic speeds. There's been a conundrum here almost since the inception of special relativity in 1905. ...
