Down, Set, Compute! Checking Quarterback Ratings with Mathematica

Comparing favorite teams and players is a favorite pastime for sports fans. Most fans, including myself, understand their sports' basic statistics—batting averages, yards per carry, and so on—but may have trouble calculating the stats. With the Super Bowl coming up in Florida this weekend, I thought it would be interesting to see what Mathematica could do to help calculate one of the most well-known and tough-to-calculate statistics of the National Football League (NFL): quarterback passer rating.

Twittering with Mathematica

The popularity of Twitter has really exploded in the past few months. The service poses a simple question: "What are you doing?" Users respond in 140 characters or less. The 140-character limit comes from the 160-character limit of SMS messages, minus a few characters for things like the user's screen name. Twitter could probably best be described as "micro-blogging." It's kind of a cross between blogging and instant messaging. People use Twitter for all kinds of reasons, everything from staying in touch with friends to receiving announcements and support from companies with a presence on Twitter. Here are a few examples:

Word Facts

Recent versions of Mathematica introduced useful data functions related to linguistics. In Version 7, Mathematica's integrated string manipulation and visualization functions provide a powerful platform for computational linguistics. Both DictionaryLookup and WordData give programmatic access to curated data that's ready for computation. DictionaryLookup has been extended to cover more languages, while WordData has information on word meaning, structure, and usage, as well as cognitive and grammatical relationships between words. Let's look at a range of examples, starting with some interesting and amusing word facts. DictionaryLookup currently contains word lists for 27 different languages:

March Madness in Mathematica

It's that time again when many of us begin to explore the pseudo-science of bracketology as the United States eagerly approaches the NCAA Men's Basketball Tournament---March Madness. It's a frenzied few weeks where statistical analysis and mathematical algorithms make a sudden leap from the desktops of professionals to the homes of millions of sports fans. As a sports fan and as an account manager working with Mathematica and Mathematica Home Edition, a wild idea occurred to me. Could someone with no professional programming training or mathematical degrees, like me, use Mathematica to create something of value, like a March Madness bracket, for someone else? While I frequently support and work with some of the brightest engineers, scientists, and statisticians in the commercial world, my personal use of Mathematica has been fairly simplistic. What could I do? I decided to find out.

Are You a Math Genius?

Wolfram Research has worked with the CBS/Paramount show NUMB3RS since its first season. Now in the fifth season, it remains the most popular show of Friday nights. "The Math behind NUMB3RS" gives a more in-depth look at some of the mathematics in each episode. With season 5, we've added a math puzzle to go with each episode. Fifteen episodes into season 5, there are fifteen puzzles available.

Word Play with Mathematica

Here in Champaign-Urbana, where Roger Ebert was raised, I took notice when Disney announced the end of its long relationship with Ebert & Roeper. Disney also announced the replacement critics, Lyons & Mankiewicz. Was there something intentional in that? A quick run on my Mathematica programs returned this anagram: Lyons + Mankiewicz = Monica Lewinsky + Z Did Disney do this deliberately? Words sometimes have hidden meaning. For over 30 years, I've been sharing puzzles with Will Shortz. Many of these I've found with Mathematica, such as computer user = supreme court, and Will has used them in his weekly NPR puzzle segment. Anagrams have of course been popular for many years. A 1936 tour de force by David Shulman is a sonnet where every line uses the letters of “Washington Crossing the Delaware.” The National Puzzlers League maintains a list of best anagrams. Also, anagrammy.com regularly ranks new anagrams as they are found. Here are some good ones:

Mapping My Travels with Mathematica

Reading Theo’s blog post about his website reminded me that our excitement about the grand projects that get done in Mathematica often make us forget to talk about all the exciting little things that Mathematica makes possible too. It would be easy to think that Mathematica is only suitable for website production if you have something on the grand scale and high traffic of periodictable.com. So I wanted to write about using Mathematica to make a website that is anything but grand and far from popular... my own. My pages are just an attempt to put my footprint on Google so that I can be found. It mostly consists of a few basic pages about me and my work with Mathematica. So what advantage did I get out of doing it in Mathematica? Well, the first was pretty basic personal practicality---why learn new tools if you don’t have to? I know Mathematica, and I knew it would be faster for me to create it in Mathematica than to find and learn how to use other content management and authoring tools. Once I had coded up a page template in the symbolic XML features of Mathematica, I could create any new page by applying that function to the page content text. The whole lot is automatically written out as HTML and uploaded to the server by Mathematica. But the one unusual part of the content is ONLY practical with Mathematica. My work with Mathematica takes me to a lot of places---giving talks about it, meeting business and technology partners and all kinds of users. I also travel for fun. I wanted to make a definitive list of places that I have been to and to present that visually.
