BP is recruiting freshmen and sophomores for their Discovery Day. This is for underclassmen to learn more about trading and supply and demand for an energy company. Students will gain valuable, real-world experiences in analytics, marketing, risk management, and supply and trading. Activities include simulations, case studies, and hands-on activities. Discover Day is on Friday, November 7 in Houston, Texas. All expenses (including travel, lodging, and meals) will be paid.
To qualify, students must be freshmen or sophomores, have a minimum GPA of 3.0, and legally authorized to work in the U.S..
The application deadline is October 3! To apply, see bp.com/istdiscoveryday
For current juniors, BP and Phillips 66 are accepting applications for their selective internship program for summer 2015. Students should apply through hiresooner.com

Power Costs Inc. (PCI) looking for interns

PCI is seeking outstanding students or recent graduates who wish to gain experience developing and implementing testing processes, performing software tests including functional, regression, etc.  Strong communication skills and proven ability to work in a team atmosphere are needed for this project.  Technical degrees and/or a strong interest in the technology field are especially helpful.

Interested students may apply at www.powercosts.com/pci-internships or may email Staci directly at swilkes@powercosts.com.


The PCI College Internship program is a structured, supervised, short-term opportunity for undergraduates, graduate students and recent graduates to perform tasks that benefit PCI as well as providing the intern with knowledge and experience. Students in the PCI Internship Program have the opportunity to build on classroom theories to make real decisions and solve relevant problems. The typical internship at PCI lasts one semester and internships are offered in the Fall, Spring and Summer. Participating students are paid and may also receive academic credit from their university. For more information please visit www.powercosts.com/pci-internships.



The 2014 Fields Medalists

Greetings readers! After a long break it seems only appropriate to open with a bang. So let us all delight in the awarding of the Fields Medal, the Nevanlinna Prize, the Chern medal and other prizes at the quadrennial (i.e., once in 4 years) ICM, the International Congress of Mathematicians. This year the ICM was held in Seoul, South Korea.


You can find out more about all the awards at the ICM site, http://www.icm2014.org or any number of news outlets:



Especially important this year is the awarding of the Fields Medal to the remarkable Maryam Mirzakhani of Stanford, the first woman mathematician to receive this award. While there have been many extraordinary women mathematicians, the award has been given only to men so far making this recognition long overdue.

Here is some more information about this year’s award winners from the official ICM site.


The four winners this year from diverse areas are: Artur Avila (CNRS Paris), Manjul Bhargava (Princeton), Martin Hairer (Warwick, England) and Maryam Mirzakhani (Stanford).

And as a final shout out we should mention that Professor Mirzakhani is also a research collaborator of former OU faculty member, Kasra Rafi.

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.
