Gender Gap Infographic

As we head into the final days of March, I’d like to share with you the following infographic sent to me by a reader. It collects some interesting (and depressing) data on women in STEM (Science, Technology, Engineering, and Mathematics) careers.

Created by: Engineering Degree

While I don’t necessarily put a lot of stock into the opening IQ numbers (see here and here for examples of problems with IQ testing), and I’m not sure if the data on course load in the first part is statistically significant, the data in the latter parts is quite compelling. I’ve discussed the psychological component of the gender gap before, but the data in the second section of this infographic provides more evidence to the claim that psychology and cultural influences, rather than biology, is behind the gender gap we see in the sciences.

The Probability Games

Though we are still a few months away from the start of the summer blockbuster season, the scuttlebutt is that The Hunger Games, opening this weekend, is expected to do huge business (and by huge, I mean upwards of $100 million). Based on the 2008 Suzanne Collins book of the same name, this property is the hottest new thing in the realm of young adult fiction, and in this post-Harry Potter, nearly-post-Twilight era of cinema history, the timing could not be better for movie executives. The book is the first of a trilogy, so whether you like it or not, these films will be with us for the next few years.

If you have not read the book, or have no idea what I’m talking about in general, a trailer for the film can be found here (sorry, embedding has been disabled for the . . . → Read More: The Probability Games

CNN Light Years guest post: Why a different voting system might be better

Hi Everyone,

In an attempt to spread the joy and cheer of mathematics to a broader audience, starting this month, I will occasionally be writing articles for CNN’s new science and technology blog, Light Years. Fear not, most of my content will still be appearing at Math Goes Pop, and every time one of my guest posts goes live, I will let you know about it here as well. Today the topic is voting systems, something I have discussed on this blog before. Here’s a piece of the intro to pique your interest:

When the results of an election (primary or otherwise) run counter to our desires, it is easy to scapegoat the political process. The right person didn’t win, we may argue, because the system itself is broken. The two-party system, for example, is sometimes cited as a leading cause of the current dysfunction in Washington. But perhaps much . . . → Read More: CNN Light Years guest post: Why a different voting system might be better

Pi Day vs. Half Tau Day

By now my views on Pi Day are well documented (see earlier posts from 2011 and 2009 if you’re curious). Recently, though, I’ve decided to try to be a little less curmudgeonly when it comes to math holidays. Consequently, while it would be easy to provide snarky commentary on articles with particularly egregious mathematical errors, this year I will try to restrain myself.

As I’ve said before, one of my biggest problems with Pi day is that the activities are, for the most part, a little ridiculous, and don’t actually do anything to better the general populace’s understanding of mathematics. Last year, I explained why contests involving the recitation of digits of are silly, so this year I’d like to offer an alternative. Why not use the day as an opportunity to debate with students the relative merits of and ?

Of course, I’m talking about more than Greek letters . . . → Read More: Pi Day vs. Half Tau Day

Shameless Self Promotion #3

Hi everyone,

A while back I was asked to contribute an essay to a book on mathematics and popular culture. I’m pleased to announce that this book is now available for purchase! There are some great essays in this book – I’ll let you decide how mine stacks up with the rest – and it also features a foreword by Keith Devlin, a Stanford University mathematician who you may know as NPR’s Math Guy.

I suggested they use my face instead, but they respectfully declined.

The price of entry is a little steep ($45), but if you’re someone interested in buying many copies (maybe you are a teacher, or maybe you just have a huge crush on David Krumholtz), I can get you a discount on bulk orders.

To whet your appetite, the title of my essay is Counting with the Sharks: Math-Savvy Gamblers in Popular Culture. Here’s the . . . → Read More: Shameless Self Promotion #3

And the Award for Best Voting System Goes to…

Last year, the Center for Election Science wrote up a quick blog post on the Oscars to motivate a discussion of voting reform. Since 2009, the Oscars have used Instant Runoff Voting (IRV) to decide the winner of the prestigious Best Picture award, but there is growing backlash against this voting system because of a number of strange properties it possesses. For example, the winner of an IRV election may not be the most favored candidate among the voters; for another strange example, it can sometimes be to your advantage to rank your preferred candidate last instead of first. Here’s a video explaining some of these weird features:

Instead of using IRV, a strong argument could be made for using Score voting (also known as Range voting). I’ve discussed these voting systems before (see here for a discussion of the 2010 Oakland mayoral race, for example), so . . . → Read More: And the Award for Best Voting System Goes to…
