Analyzing US 2008 Elections with Mathematica

The 2008 United States presidential election is arguably the most interesting US presidential election in my lifetime.

Already, millions of Americans have registered to vote for the first time in their lives.

Regardless of the outcome, America is going to elect either its first black president or its first female vice president.

America will elect a sitting US senator to the highest office in the land—which, until now, has only occurred twice in US history (Warren Harding and John F. Kennedy were US senators).

Both presidential candidates were born outside of the continental United States.

If elected, John McCain will be the oldest sitting US president upon ascension to the presidency.

Never before in US history has there been such a large disparity in age between the two presidential candidates, either.

It’s also the first election you can analyze using Mathematica 6.

Seeing beyond a Theorem

Mathematics is a notoriously technical subject that prizes exactingly precise statements. The square of the hypotenuse of a right triangle is the sum of the squares of the legs, not the sum of their cubes, nor the difference of their squares. Such precision produces the clarity that makes the subject so powerful, but occasionally it comes at the cost of easy understanding. Indeed, more-complicated mathematical statements often sound bewildering upon first reading. Take the following theorem in plane geometry (deep breath...):

Let ABC be a triangle. Let DEF be parallel to AC with D on AB and E on BC. Let FGH be parallel to AB with G on BC and H on AC. Let , , and be the radii of the incircles , , and of the triangles ABC, DBE, EFG and HGC, respectively. If F is outside of ABC, then . Got it? Many theorems of mathematics, including this one, are easier to communicate by picture than by words. Here’s the scenario described in the theorem (images in this post are produced by slightly modified versions of the code for the Demonstration “The Radii of Four Incircles,” which is one of nearly 200 Demonstrations about theorems in plane geometry written by Jay Warendorff for the Wolfram Demonstrations Project):

Going Wordless at the Advanced Mathematica Summer School

No, not a vow of silence, but rather, some suggestions about how to move documents from Microsoft Word into Mathematica. A number of us Wolfram Research staffers contributed to our recent Summer School effort by sharing mentoring duties. In my case I worked with Richard Werthamer, a physicist who is publishing a book on the science of casino gambling strategies. His project includes programs verifying his research, and he’s eager to translate them into Mathematica in order to exploit all the new dynamics and plotting features of Version 6. At the same time, he quite naturally wants to move his existing manuscript into Mathematica notebook form to deliver a computable document, combining text and interactive Mathematica content distributable on the Mathematica Player platform. Richard’s situation is pretty common. He prepared his manuscript with MS Word, and a great new feature delivered in Mathematica 6.0.3 allows for the exchange of MathML on the clipboard with MS Word 2007 straight “out of the box”. In other words, after creating a formula in Word using its new native math typesetting system, simply select the formula, copy, then switch to Mathematica to paste into a notebook.

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:

A Demonstrations Project Update

As the project coordinator for the Wolfram Demonstrations Project, I’ve seen a lot of new exciting features we’ve been working on come to fruition recently and I want to tell you about them. I hear from a lot of our users, and want to let you know that we are listening to you and working on features that will make communicating your ideas, sharing your work and learning about Demonstrations even easier. And trust me, even more features are coming! Here are some of the most recent updates we’ve made to the Wolfram Demonstrations Project.

Return of the NKS Summer School

I am lucky enough to find time to blog again about the NKS Summer School. Every year is different (see last year’s post), but some things remain the same. Everyone is very active: students doing homework and developing their projects, the instructors helping them and giving lectures and Stephen Wolfram advising students and doing live experiments. As Yoda said, “Do, or do not. There is no try.” Other sayings appropriate to our task: “Never give up, never surrender,” and “If you fall off a cliff, you might as well try to fly.” We are always doing something new at the Summer School, often using the latest features of Mathematica, but there is an intrinsic difference this time. We have more students and more instructors than ever before, which makes this brand of intense science even more intense.

Launching the Mathematica Scrapbook

(Two posts from me in short succession. Forgive me. I promise that I won’t frequent this forum more than is bearable—hopefully. But I’ve been asked to do a post about the Mathematica scrapbook that we’ve just made public, so here I am again.) As I said in my last post, June is a special time around Wolfram Research. Given the fact that June 23rd was the 20th anniversary of Mathematica, there’s been more celebration this June than usual. We started talking about the significance of Mathematica’s 20th birthday and what we should do in commemoration some time ago. We decided that one thing we would like do would be to create an online scrapbook.

Mathematica Turns 20 Today

Today is an important anniversary for me and our company. Twenty years ago today—at noon (Pacific Time) on Thursday, June 23, 1988—Mathematica 1.0 was officially launched. Much has changed in the world since then, particularly when it comes to computer technology. But I’m happy to be able to say that Mathematica still seems as modern […]

The Mathematica Memory Museum

June is a special time around Wolfram Research. Every year we have a big company picnic to celebrate the anniversary of the release of Mathematica, which occurred June 23, 1988. That’s right, Mathematica turns 20 years old this month.

When you think about it, having a 20th birthday is pretty remarkable for a piece of software. How many other software products do you use now that were around in 1988? More importantly, how many of them are still at the top of their game after so long? We’re pretty proud of the fact that Mathematica’s core design and functionality have stood the test of time.

We thought it would be appropriate to celebrate this anniversary by having a “memory museum” at this year's picnic. Being the de facto company archivist (having once been the corporate librarian and having reached the “relic” status in both raw age and tenure at the company), I took on the role of organizing our displays.

We had a big collage of photos of employees past and present. An awful lot of blood, sweat and tears have gone into the creation of Mathematica over the years and it only seemed right to highlight the people behind the product. Anyway, it’s always fun to note the passage of time through funny hairdos, expanding waistlines and receding hairlines.

We wanted to show how Mathematica has changed over time, too. We came up with a few displays that seemed to show this fairly well. Here’s a graphic we used as a poster to show the disk space used by each of our major versions.
