# Party! Party! Party!

End of the year Math Club Party! Congratulate our departing seniors! Share your summer plans with your friends! Participate in fun math games and partake in pizza and cake!

It’s this

Wednesday, April 24th at 5 pm in PHSC 1105!

A Better Idea

As always, Free Pizza! + Free Cake!

# Math Club on Wednesday!

Dr. Paul wondering who stole all the books from his shelves..

Dr. Sean Paul, a professor at the University of Wisconsin, will be speaking in the Math Club this

Wednesday, April 3rd at 5 pm in PHSC 1105.

Fun Fact:  Dr. Paul is a Sooner!  He graduated from OU in 1996 and then went to Princeton for graduate school.  If you’re thinking about going on to grad school, here is a great chance to ask him for “real world” advice about how he went from OU to Princeton.

Dr. Paul will be talking about “The Cayley GKZ Theory of Discriminants, Resultants, and Multidimensional Determinants”.  Here’s the abstract:

When do two complex number polynomials have a common root? When does a given polynomial have a double root? What is the determinant of a two by two by two matrix (the third “two” is not a typo) ? What is the determinant of a sequence (i.e. complex) of matrices?

We will give answers and hints to some of these questions in the talk.

— Dr. Paul’s abstract

There will also be the canonical Free Pizza!

# Math Club on Wednesday, March 13th!

When it rains, it pours!  There is a Math Club this

Wednesday, March 13th, at 5 pm in PHSC 1105.

Dr. Crowell

The talk will be by Sean Crowell.  He earned his PhD from the OU math department last year and is now a postdoctoral researcher on south campus at the National Weather Center.  He is a mathematician working on the problem of modeling the weather and that’s what he’ll be talking about:

Title:  Using Mathematics to understand and predict the weather

Abstract:  All of us benefit from the enormous volume of weather observations and forecasts.  Where does all of that information come from?  Believe it or not, mathematical techniques are the foundation on which these different informational products rest. In this talk we’ll discuss how computers draw weather maps, how to use mathematics to track tornadoes, and how we use noisy observations and imperfect numerical weather prediction models to create a useful weather forecast.

And, naturally, there is the canonical Free Pizza!

By the Power of Google, we discovered that Sean is also a fellow math blogger.  You can read his posts here (as “That Weird Math Guy in Oklahoma that Loves Weather and Climate”).  That should be no surprise as Sean is keen on publicizing science and math and is a driving force behind Norman’s Science Cafe (In fact, there’s a Cafe tonight! Check Sean’s links for details.)

Apropos, we have to share the coolest thing we’ve seen this week.  It’s a real time map of the wind across the US.  Here is what the wind looks like right now:

“Oklahoma, where the wind comes sweepin’ down the plain”

Or, if you’re in Calc IV right now, it’s nothing but a vector field!

# Math Club this Wednesday!

There is a Math Club this

Wednesday, March 6th at 5 pm in PSHC 1105!

Dr. Catherine Hall, the OU Math Department’s Undergraduate Advisor, is going to give you the run-down on undergraduate friendly conferences, REUs and other fun math activities you might not know about.   In particular, Dr. Hall went to TORUS (Texas-Oklahoma Research conference for Undergraduate Symposium) and wanted to share that experience with everybody.

And, of course, there’ll be the usual Free Pizza!

Good ol’ xkcd

# Math Club with Adrienne Jablonski!

There will be the first Math Club of the semester on

Wednesday, February 6th at 5 pm in PHSC 1105.

As summer/graduation approaches, one’s thoughts turn to jobs.  Adrienne Jablonski will alk about jobs, internships, how to write a cover letter and a resume.  Don’t miss it!

Plus, there’ll be the usual Free Pizza!

# PCI @ Math Club!

Recruiters from Power Costs, Inc (PCI) iwill be talking this

Wednesday, November 14th in PHSC 1105 at 5pm.

PCI is a  Norman based company that offers asset optimization solutions for power generation and trading companies.  They are keen to hire people with a math background for internships and full time jobs.  They’ll give a career presentation to the Math Club where they talk about the sorts of things people do at PCI.

And, of course, there’ll be Pizza!

# Andy Magid in Math Club!

Dr. Magid in 1980

On

Wednesday, April 11th, at 5 pm in PHSC 1105

our own Andy Magid will be talking in the Math Club about Boolean Algebra.  That’s the mathematics of zeros and ones.  Well, it’s a bit more than that!  It shows up in abstract algebra, and is at the center of computers (binary anyone?) and mathematical logic (True vs. False).

It should be a very interesting talk.  Here’s the title and abstract if you want to know more:

Title:  Boolean Algebra, Operations, and Rings

Abstract:  Z/2Z valued functions on a set correspond to subsets of the set, and vice versa: the support of a function is a subset and the characteristic function of a subset is a function. From this correspondence can be derived ring operations (addition and multiplication) on subsets and subset operations (intersecti0on and union) on functions. And new operations on both.

And of course there’ll be the usual Free Pizza!

George Boole doesn't take maybe for an answer!

# Random Walks with Erin Pearse

This

Wednesday, March 28th at 5 pm in PHSC 1105

will be a Math Club talk by our own Erin Pearse.  He’ll be talking about random walks:

Erin Pearse on a more colorful day.

Title: Exploring networks with random walks

Abstract: I will give a brief introduction to the theory of random walks on networks, including mixing times and convergence to stationarity. I’ll give a brief description of Monte Carlo techniques and explain the application of random walks in this context. Next, we’ll look at diffusion mapping, a framework for dimensionality, clustering, dataset parametrization, and inferencing that is constructed using random walks. I’ll show how this technique applies to machine learning and give an example of that forecasts the success rate of students at OU. This talk will be accessible to anyone who can multiply matrices and has a vague idea of what a discrete probability distribution is.

And, of course, there’ll be the usual Free Pizza!

No word on if the Ministry of Silly Walks will be involved.

# Movie Night!

The first Math Club of 2012 is this

Wednesday, February 1st at 5pm in SCI 324.

Notice that we’re in the Film and Media Studies Lounge in Old Science Hall 324.  That’s right next door to PHSC.  Here it is on the campus map:

Click on the map to make it bigger.

We’ll be watching the Best Picture nominated film MoneyballWe learned from John Paul Cook last semester that there is lots of interesting math in the Moneyball story.  Plus there’s Brad Pitt (An Okie!), Jonah Hill, and baseball.  Something for everyone!

Here’s the trailer:

And, as always, Free Pizza!

# Dr. McCullough in Math Club

We have good news and bad news.  The good news is that our own Dr. Darryl McCullough is speaking in the last Math Club of the semester on

Wenesday, November 30th at 5 pm in PHSC 1105.

He will be speaking on “First-year calculus, revisited“:
