Here are some items I have created/modified/outright stolen for use in my class.
In my opinion (regarding the stealing…) if you’re going to put useful things on the internet, you should probably assume that people are going to use it.
To that end (and to polish up my karma a bit), here are my useful things. I will add more as they come. If you also think they may be useful, please feel free to use them! I’d love to hear if you have any comments on them. If you make any modifications, I’d love to see what you’ve done. Science (and the teaching thereof) is a collaborative effort, right?
