10/8/2017 | We'll be talking about the classic Liars and Truthtellers puzzles, how to solve them, and how to classify them. [Show less] |

10/22/2017 | [Show less] |

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. [Show less] |

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! [Show less] |

11/12/2017 | What if we took derivatives of sequences instead of functions? It turns out, we can still learn a lot! [Show less] |

11/19/2017 | [Show less] |

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. [Show less] |

12/10/2017 | Quick, fun, team-based math competition with prizes! [Show less] |

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! [Show less] |

1/21/2018 | The study of projective and affine finite geometries, and their applications to non-geometric problems [Show less] |

1/28/2018 | We looked at the strange algebraic objects known as Quandles, and their applictions to classifying knots. [Show less] |

2/4/2018 | We re-introduced arithmetic functions, now in the context of number theoretic problems, culminating in classifying even perfect numbers. [Show less] |

2/11/2018 | We continue studying arithmetic functions, proving results on mobius inversion and using them to approximate the size of arithmetic functions. [Show less] |

2/25/2018 | The sum of the reciprocals of the primes, plus the prime number theorem (to within a constant factor). [Show less] |

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? [Show less] |

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. [Show less] |

4/15/2018 | We'll be learning about Infinity and Set Theory with guest instructor Dr. Omer Ben-Neria [Show less] |

4/22/2018 | We'll be continuing our exploration of rational points by exploring congruent numbers: the areas of rational-sided right triangles. [Show less] |

5/20/2018 | We'll study several mathematical impediments to crossing a river. [Show less] |
