In this session, we leave the comfortable planar world and take a peek at Logical Geometry in the Third Dimension. Math Circle OnlineSaturday 2 May 2020, 9:30-11:00AM Check your email for login instructions.

We will take a look at still larger systems of finite geometry. Along the way, we will investigate a broken arithmetic system (and how to fix it). Math Circle OnlineThursday 30 April 2020, 4:00-5:30PM Check your email for login instructions.

We continue our investigate of finite geometry – what new geometry do we get when we replace modulo 2 arithmetic with modulo 3 arithmetic? Math Circle OnlineSaturday 25 April 2020, 9:30-11:00AM Check your email for login instructions.

The Math Circle meets this Wednesday afternoon. What happens when combine Logical Arithmetic with Lines to Infinity? We’ll invent a new system of geometry that’s much simpler than the one you learned in school. Math Circle OnlineWednesday 22 April 2020, 4:00-5:30PM Check your email for login instructions.

This Saturday, we’ll continue our study of “very close” rational solutions to the sqrt(N) problem… finding an approximate value for sqrt(61). Then we’ll take a look at an ancient puzzle by Archimedes about counting the number of cattle in Sicily.

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.

Some numbers are square; some numbers are triangular. Let’s explore a connection between the two. Math Circle OnlineWednesday 8 April 2020, 4:00-5:30pm Look for the email with login instructions.

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.
