Two of my calculus students today approached me at the end of class (this was the last time I was going to see them before winter break) and handed me
as a present. Indeed, if you identified this as a finger puppet of Newton, you would be correct! They said they looked for a Leibniz too, but one didn’t exist. Of course if one did exist, things might have gotten a little dangerous. Goodness knows I might have had to create a few history of calculus videos (a la Potter Puppet Pals).
All I have to say is: hooray for my “histoy of calculus” webquest!
