10/8/2017
We'll be talking about the classic Liars and Truthtellers puzzles, how to solve them, and how to classify them.
10/15/2017

10/29/2017
Real world random numbers don't look quite as random as some people think. Benford's law is an explanation of some surprising regularity.
11/5/2017
An amazing magic trick, in which a magician can untie any tangle just by being told a single rational number. We'll figure out how it works!
11/12/2017
What if we took derivatives of sequences instead of functions? It turns out, we can still learn a lot!
11/19/2017
12/3/2017
We'll look at how to divide by 2, how to subtract, and if we're really making good progress, how to divide by 3. No, really. And this may be the hardest week of the quarter.
12/10/2017
Quick, fun, team-based math competition with prizes!
1/14/2018
We'll look at geometries with finitely many points, see what's geometric about them, and also find applications to the real world!
1/21/2018
The study of projective and affine finite geometries, and their applications to non-geometric problems
Handouts:
1/28/2018
We looked at the strange algebraic objects known as Quandles, and their applictions to classifying knots.
Handouts: Week 3 Handout
2/4/2018
We re-introduced arithmetic functions, now in the context of number theoretic problems, culminating in classifying even perfect numbers.
Handouts: Week 4 Handout
2/11/2018
We continue studying arithmetic functions, proving results on mobius inversion and using them to approximate the size of arithmetic functions.
Handouts:
2/25/2018
The sum of the reciprocals of the primes, plus the prime number theorem (to within a constant factor).
Handouts:
3/4/2018
What are all the ways we can hang a painting with a string using 1 nail? What about 2 nails? n nails?
4/8/2018
Finding rational solutions to algebraic equations goes back to the ancient Greeks, but these days this problem finds applications ranging from pure mathematics to cryptography.
4/15/2018
We'll be learning about Infinity and Set Theory with guest instructor Dr. Omer Ben-Neria
4/22/2018
We'll be continuing our exploration of rational points by exploring congruent numbers: the areas of rational-sided right triangles.
4/29/2018
5/6/2018
5/20/2018
We'll study several mathematical impediments to crossing a river.
