Millimeter waves are infrared rays. I'm surprised you didn't know that! Oh, wait. You did, if you are one of these people:
Steve J (the J stands for Just Another Ray)
Steve T (the T stands for The Incredible Hulk)
Gamma rays are infrared, too, even though they make Bruce (or David) Banner go all green. They also can make topaz change from white to blue. Go figure.
Anyway, today is Friday the 13th, which means things are supposed to turn less lucky. Or unlucky. Or bad lucky. I don't know, I'm not that superstitious (knock on wood). Here's today's (cross your fingers) completely unjinxable trivia question:
According to a recent Dutch study, do more or less accidents occur on Friday the 13th's compared to Fridays that fall on any other date?
