  6. OK, it turned out my Analysis class DID want to know about the history of calculus AND they wanted to avoid new work. Fun discussion. 12:27 PM Nov 24th from Brizzly
  7. My Real Analysis class wants me to talk about the hist of calculus today. Are they interested or is this just a ploy to avoid new material? 10:20 AM Nov 24th from Brizzly
  8. @timchartier That's crazy about plagiarizing a teaching statement. Good job catching it. 8:31 PM Nov 23rd from Brizzly in reply to timchartier
  9. @timchartier We found a bunch of math documents on the website, but suspect that one student uploaded them all. 8:30 PM Nov 23rd from Brizzly in reply to timchartier
  10. Cool! A geometric invariant for meandering rivers on Science Friday http://bit.ly/6YxJ2d 1:46 PM Nov 23rd from bit.ly
  11. @ITChE Actually, in full disclosure, my colleague noticed it. 1:30 PM Nov 23rd from Brizzly in reply to ITChE

  14. @timchartier Saw your post about paper mills. Have you had students uploading math solutions to CourseHero? 6:07 AM Nov 23rd from Brizzly in reply to timchartier
  15. The International Congress of Mathematicians 2010 now has a twitter feed @ICM2010. I'm looking forward to going. 6:04 AM Nov 23rd from Brizzly

  17. @mathheadinc It was Zill and Wright's Calculus book (I've never heard of it before). 2:36 PM Nov 21st from Brizzly in reply to mathheadinc
  18. In big letters on a promotional flyer for a new calc book: "Yes! Your students can pass calculus." Way to set high standards! 12:57 PM Nov 20th from Brizzly
  19. New blog post: Legendre who? Not who we thought he was. http://bit.ly/4eBr19 2:24 PM Nov 19th from bit.ly
