3 things that keep poor kids out of the sciences

There is some truth to the American ideal of meritocracy. But there's a lot of myth, as well. Biologist Danielle Lee describes her experience coaching poor kids in St. Louis on science fair projects — an activity that often becomes a stepping stone to a career in the sciences. But, for the kids Lee met, intelligence and a good idea aren't enough to overcome the institutional barriers working against them. This is how discrimination happens. It's not simple and easy to fix and it isn't pretty to watch. Maggie

Different names for the same thing: Visualizing the 2012 election

Did you know that there was a major American election on Tuesday? Great. Let us all never speak of it again. At least for the next 3.5 years.

But before we send the parts of our brains that care about politics off to recuperate at a nice imaginary spa, take a quick look at a page of election maps put together by University of Michigan physics professor Mark Newman. He studies complex systems, including the networks of human relationships and decision-making that go into election results. His page of maps shows several different ways to visualize the same 2012 presidential election data — methods which provide different pieces of context that you don't normally see in the simple state-by-state map.

The basic map — the one you see on TV and in the newspaper — doesn't really tell you the whole story. It gives you no idea of population density (a factor that obviously matters a lot in tallying the popular vote), and it only shows the winning party in each state. In reality, the vote is seldom all-Democrat or all-Republican. There's a gradient, no matter where you live.

The map above takes both those factors into account — distorting the country to make the more populous parts larger, and showing split turnouts in shades of purple.

The infrastructure of longevity — a systems-level perspective of living to 100

I really enjoyed reading a recent story in The New York Times Magazine about attempts to understand extreme longevity — the weird tendency for certain populations to have larger-than-average numbers of people who live well into their 90s, if not 100s.

Written by Dan Buettner, the piece focuses on the Greek island of Ikaria, and, in many ways, it's a lot like a lot of the other stories I've read on this subject. From a scientific perspective, we don't really understand why some people live longer than others. And we definitely don't understand why some populations have more people who live longer. There are lots of theories. Conveniently, they tend to coincide with our own biases about what we currently think is most wrong with our own society. So articles about extremely long-lived populations tend to offer a lot of inspiring stories, some funny quotes from really old people, and not a lot in the way of answers.

Buettner's story has all those elements, but it also proposes some ideas that were, for me, really thought provoking. After spending much of the article discussing the Ikarian's diet (it's low in meat and sugar, high in antioxidants, and includes lots of locally produced food and wine) and their laid-back, low-stress way of life, Buettner doesn't suggest that we'll all live to be 100 if we just, individually, try to live exactly like the Ikarians do. In fact, he points out that other communities of long-lived individuals actually live differently — Californian Seventh-Day Adventists, for instance, eat no meat at all and don't drink, and they live with the normal stresses of everyday American life.

What these groups do have in common, though, is a strong social infrastructure that ties people to each other emotionally and connects individual choices to a bigger community lifestyle.

Energy is more than sources; energy is systems

When we talk about energy, we often talk about it in very disconnected ways. By that, I mean we talk about new renewable generation projects, we talk about cleaning up dirty old power plants, and we talk about personal decisions you and I can make to use less energy, or get more benefits from the same amount.

What we fail to talk about is how all those ideas fit together into a coherent whole. And that matters, because our energy problems (and our energy solutions) are about more than just swapping sources of power or making individual choices. We have to fix the systems, not just the symptoms.

Back in April, I got to go on Minnesota Public Radio's "Bright Ideas" to talk about my book, Before the Lights Go Out. Now MPR has the entire hour-long interview up on video. You can watch the whole thing if you want. But, if you're short on time, I'd recommend the stretch from about minute 8:30 to 10:50. That's where I explain in more detail why systems—infrastructures—are so important and why we can't solve our energy problems without focusing on how choices and sources fit into those larger issues.

Watch that clip, then read this Minneapolis Star-Tribune article about how investments in transportation-oriented bicycle infrastructure have changed the way Minneapolites think about biking and dramatically increased the number of people who choose to bike. I think you'll see some thematic connections.
