Catenary curves continued!

February 22, 2012

Last week, we started construction on a catenary curve. We were pretty close to finishing by the end of the meeting, but there is still some work to be done. Come help us put the finishing touches on our cardboard masterpiece tomorrow in the lobby of Ritter Hall from 4pm – 5pm! See you there!

Catenary curves

February 14, 2012

This Wednesday from 4-5pm, we will look at catenary curves, like our own Gateway Arch. The equation for a catenary curve is of the form

y = a\cosh(\dfrac{x}{a})

But they look so much like parabolas! How are these curves like parabolas? How are they different? Come find out about all sorts of these types of curves in the lobby of Ritter Hall from 4-5pm tomorrow! Refreshments will be provided. Bring your friends!

QR Codes: A Wealth of Information

February 6, 2012


This Wednesday, (Feb. 8.), Michael Schade, a SLU undergrad, will give a talk about QR codes like the one you see above. Bring your camera-enabled smart device if you have one–if you’d like to come prepared, you can find a reader for your device at

As always, we’ll meet in the lobby of Ritter Hall from 4:00pm to 5:00pm to enjoy refreshments and math!

Polygonal Foldings and the Fold-and-Cut Theorem

February 1, 2012

I like turtles

This Wednesday, we will be joined by SLU’s own KYLE SYKES. Kyle is a grad student who will talk about Polygonal Foldings and the Fold-and-Cut Theorem!

Abstract. The field of Discrete and Computational Geometry has many awesome applications and many accessible problems that are just asking to be solved! We will look at several of the open problems related to polygonal folding (and polyhedral unfoldings!). What is polygonal folding you might ask? Come and find out! We’ll get our hands dirty with making polyhedra from scratch and demonstrate one of the most mindblowing theorems in the field, the Fold and Cut Theorem!

We will be meeting in the lobby of Ritter Hall from 4-5. You will be amazed at the refreshments we will provide especially for you!
