Over at Five Thirty Eight, Walt Hickey has a piece about cheerleading as a sport and injury rates, which is both a nice look at the way to use stats to measure the real danger level of an activity, and the sort of small details that can be teased out. The piece includes a table […]
Jonah Lehrer has a big article at Grantland on concussions in high school football that paints a fairly bleak picture: The sickness will be rooted in football’s tragic flaw, which is that it inflicts concussions on its players with devastating frequency. Although estimates vary, several studies suggest that up to 15 percent of football players […]
SteelyKid is off spending a weekend at Grandma and Grandpa’s, so this week’s picture was actually taken early Wednesday morning: The early hour accounts for both the pacifier (she wasn’t willing to give it up yet) and the frizzy hair (bed-head toddler!). I’m pretty sure she hasn’t grown measurably since yesterday, though. This photo is […]
I missed the first 15 minutes of yesterday’s World Cup final because it was inordinately difficult to find a tv showing the game at BWI airport. There are tvs all over the place, but they’re all locked into playing a pre-recorded loop of CNN programs, without even a news ticker that could give score updates. […]
I was under the impression that the World Cup semifinals didn’t start until tomorrow, but I was wrong about that. So here’s a hastily-posted Open Thread for discussion of the games. Will Uruguay manage to carry the honor of South America into the final game? Or is South America doomed to be the Big East […]
The dogphysics karma joke is pretty much dead, as countries with current or future editions of How to Teach Physics to Your Dog have gone a dismal 1-3-0 in the first round of elimination play. I’m surprised it lasted as long as it did, honestly. The big story of the World Cup at the moment […]
The last two days of group play were kind of disappointing, with two games (Brazil-Portugal and Spain-Chile) barely being contested in the second half, as the teams involved were sure to advance, and just sort of kicked the ball around idly in the middle of the field until the clock ran out. In a just […]
The US managed to survive yet another appalling lapse of officiating and beat Algeria 1-0 on a goal in stoppage time. Simultaneously (in some frame of reference), England beat Slovenia 1-0. With South Korea advancing yesterday, countries with current or forthcoming editions of How to Teach Physics to Your Dog are 3-0 when it comes […]
Three European countries, France, Germany, and Spain have suffered embarrassing World Cup losses. The French team in particular has appeared to be in complete disarray. Their combined record to this point is just 2-3-1 (W-L-T). What do these three countries have in common? None of them have purchased translation rights for How to Teach Physics […]
Friday’s games showcased everything that makes international soccer maddening for Americans to watch: dreadful officiating, lack of scoring, and annoyingly conservative strategy. The referee in the Germany-Serbia game handed out cards like it was a poker tournament, with the result that, in the second half, every time two players got within about a meter of […]
