Square Root of N (Almost)

The Math Circle meets this Wednesday afternoon. We’ll continue our study of “very close” rational solutions to the sqrt(N) problem. Math Circle OnlineWednesday 15 April 2020, 4:00-5:30PM Check your email for login instructions.

Square Root of 2 (Almost)

The Math Circle meets Saturday to continue the topic: Squares and Triangles. We will see how it ties into a famous equation that (almost) gives the square root of 2, and was studied by Pythagoras, Archimedes, Brahmagupta, and Fermat.

Dividing a circle

What happens when we divide a circle into different regions? An interesting pattern emerges… or does it? Math Circle OnlineSaturday April 4 9:30-11:00 AM Look for email for login instructions.

Battle at Sol 3

This is a continuation of our introduction to Mathematical Modeling – applying math to simulate and make predictions about real world systems, using Google Sheets. The planet Sol 3 is under attack from a virus pandemic. We apply our modeling skills to the current COVID-19 crisis. How does an individual’s behavior affect the outcome of …

Erratic Quadratic Pt. 2

Our study of the Quadratic Formula continues… we’ll look at a way to solve quadratic equations without doing any calculations. Math Circle OnlineWednesday March 25, 2020 4:00-5:30PMFree of charge Look for login instructions in your email.

Erratic Quadratic

Every math student learns a magical mathematical formula that goes something like this: “Negative B Plus or Minus the Square Root of …“. We’ll take a look at this formula from some unusual angles (e.g., from upside down…). Math Circle OnlineSunday March 21, 2020 1:00-2:30PMFree of charge Look for login instructions in your email.

Lines to Infinity

Let’s take look at straight lines from a new perspective. We’ll see that the basic building blocks of geometry – points and lines – are really not all that different. Then we’ll take a brief visit to infinity (and beyond). Join us for an online session of the Math Circle. When: Saturday March 14, 10:00 …

Monday is One Day

The Math Circle resumes this weekend for the topic: “Monday is One Day”. My birthday was on a Monday this year – I really hate that… but it will be on a Saturday in 2024 – much nicer! Following the approach of mathematician John Conway,  we will learn how to apply modulo 7 mental arithmetic …
