The Rubik’s Cube celebrates 40 years.

The beloved Rubik’s Cube turns 40 this year. And a celebration is under way to celebrate its enduring appeal. Created by Erno Rubik, a Hungarian architect and designer, it was initially sold as a toy at fairs before becoming an international phenomenon. “Speed cubing” is a recognized championship sport where participants compete to solve a randomized cube in the shortest possible time. The world record: 5.5 seconds.


The cube has inspired a lot of beautiful mathematics including the notion of a Rubik’s cube in higher dimensions (and an appropriate algorithm to solve it).

OU Math Club: last talk of the academic year!

The last meeting of the Math Club will be on Wednesday, April 23rd at 5:00 pm in PHSC 1105 (as usual). There will be a talk by our own Christina Durfee followed by a PARTY!! There could even be cake…

Title of talk: “Killing the Hydra: A practical application of graph theory”


Speaker: Christina Durfee, University of Oklahoma, Department of Mathematics.

Abstract: The hydra is a creature with many heads.  It is particularly difficult to kill, as each time you cut off one of its heads, two new ones grow back.  The hydra can be represented by a type of graph known as a rooted tree, whose heads are the vertices of degree 1.  The heads can be cut off and new heads will grow back according to certain rules.  In this talk we will explain the hydra problem in more detail and discuss whether there is a strategy to kill this beast.

TED Math talks.

TED is a nonprofit devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages.

Here is a collection of some entertaining and excellent TED talks in mathematics.


BP Trading Simulation, April 10th

BP is an oil company but they also have a financial division that trades in the oil exchange system. If you would like to know more about what they do and opportunities for internships with their trading unit, here is a fun way to immerse yourself in the process and discover what they do. BP will hold a trading simulation in Adams Hall on Thursday, April 10th at various times. Here is the flyer:
