    This is a (7/7) thread of the recent drawings I have done of my favorite artists (including mathematicians, writers, and philosophers). These are all pen and paper on standard printer paper. First up, the one and only Georg Cantor.

  2. Took a drawing lesson from Escher's woodcut print "Puddle".

    A discrete continuum?

    Artist's note: there's no joke or deeper meaning, at least I don't think so. I just drew the river and some mathematicians started talking about it.

    Two mathematicians argue by a river.

    I've decided to not drink for the month of February (or more), though I don't think it really matters either way. It seems like a nonsensical experiment. Cheers!

    Proof that the limit of x^2 as x goes to 2 is 4.

    It was 10 years ago today that I took my first Logic course (with Professor Hamkins), and began to gain knowledge about the foundations of math. Also, I think it is his birthday this weekend. Happy Birthday, Joel.

    Imagine a world where there is no concept of 2, and yet it exists as a memory, or a dream. We see "two" apples, perceive them, perhaps enjoy them. Then another apple is placed, and we do the same but this time might also think 3, the number. Alice is there, looking for primes.

    Short thread on my class today: This class is Business Calculus 1, for the business students at Fordham. The previous lessons had been a review of trig and exponential and logarithmic functions (after a review of inverses). So today was the first true calculus lesson. 1/n

    Overall, I felt they did a great job. Any thoughts on teaching the definition of derivative before officially teaching limits? 10/10

    In the end, every student did at least 2 problems in class and some did all 5 using the definition. For the limit part, they had the strategy to do algebra to cancel the h and then when it is possible, plug in h=0. We will go over limits in detail soon. 9/n

    They did a great job and everyone seemed to get the main idea: the derivative is the slope of the tangent line. Then I did another example of finding the derivative with the definition for f(x) = sqrt(x). Then they had this worksheet - had to use the limit definition. 8/n
