As I mentioned a few months ago, I briefly joined an undergraduate research seminar my freshman year at Cornell. In that seminar I was asked if a two-dimensional random walk on a lattice would return to the origin infinitely often. I said of course. The advisor was impressed until he asked about three-dimensional walks and I said they also hit the origin infinitely often. My intuition was wrong.
33 years later I'd like to give the right intuition. This is rough intuition, not a proof, and
I think we have all been there (or maybe it is wishful thinking that I am not alone:)… The class is sharing strategies for solving a problem and all of a sudden, one student explains his/her “shortcut” or algorithm to the class. It’s true, it works, and you know you will get there, but my […]
The following was written by Stacey Alexeeff, NSF postdoctoral fellow. Thirty hours of travel brought me from Colorado to New Jersey to Mumbai, and finally to Kolkata, India for the VI-MSS Workshop on Environmental Statistics. Jointly organized by the Indian … Continue reading →
I have been involved in a lesson study group for the past few months and today was the day that my class was being observed. Monday, 8 am, grade 10 applied class with an extra 4 teachers and the principal - how could that not be fun?!? I joke, but it was fun!We began with our counting circle. Today we started at 62 and counted down by 13. We stopped after the first student to talk strategy. I thought it was really interesting that he said he just knew the answer, but when pushed a little more
