Wax On...Wax Off

• Posting a scathing comment about me to RateMyProfessor.com on the same morning that you come to my office hours to plead for a passing grade is pretty risky, especially when I subscribe to the RSS feed!
  
• And people criticize string theory for being too pie-in-the-sky? Here's a concrete representation of it for just $90. That may seem cheap, but just remember than you need to buy something like 10 raised to the power of 500 of these to get something like our universe!
  
• Teaching Tip #436: I've long been aware of a glaring weakness in my teaching; I'm bad at repeating things. In particular, I suck at reviewing things. I suppose it's because I'm pretty spare with my speech in the first place, and I tend to either understand something right away or I ask questions. So I've always simply expected students to ask if they don't get it. Of course, this often doesn't happen. Anyway, you might think just recognizing this defect means I could easily fix it, but not really. So here comes the tip: teaching is a bit like painting in which one needs to brush in various directions to fill in spots and establish a good covering. It may sound a bit corny, but it really helps me come into lecture each day and try saying the same things from previous lectures a bit differently.
