drorzel | May 11, 2014Over 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 of injury rates for a wide variety of sports, seen above as the "featured image" and reproduced below. I don't really have anything much to say about cheerleading, but one thing did jump out at me from the table, leading to the question in the post title.

milhayser | April 6, 2014Perovskite solar cells can not only emit light, they can also emit up to 70% of absorbed sunlight as lasers.
Critical signaling molecules can be used to convert stem cells to neural progenitor cells, increasing the yield of healthy motor neurons and decreasing the time required to grow them.
Mexican blind cavefish are so close to their sighted kin that they are considered the same species, but they use pressure waves (from opening and closing their mouths) to navigate in the dark.
Electrostatic assembly allows luminescent elements (like Europium) to be embedded in nanodiamonds; these glowing…
milhayser | February 23, 2014Researchers observed tiny voids forming in silicon used for solar panels; these voids provide physical evidence of the Staebler-Wronski effect, "which reduces the solar cell efficiency by up to 15 percent within the first 1000 hours."
Using an online avatar with a skin color other than your own makes you less racist in real life; playing a hero makes you less cruel, and playing a villain less benevolent.
Old mouse muscles exhibit "elevated levels of activity in a biological cascade called the p38 MAP kinase pathway" which prevents stem cells from dividing and repairing muscle damage. By…
drorzel | January 11, 2012Jonah 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 suffer a mild traumatic brain injury during the season. (The odds are significantly worse for student athletes -- the Centers for Disease Control and Prevention estimates that nearly 2 million brain injuries are suffered by teenage players every year.)…
drorzel | December 9, 2010SteelyKid 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 in honor of SteelyKid's sporting activities, as part of the SoccerTots program. Several weeks ago, before the time change, I was lamenting the fact that cold weather and early sunsets were going to make it harder to tire SteelyKid out by letting her run around…
rallain | September 7, 2010You can call it football if it makes you happy. Anyway, this is a popular story going around. The physics of the magic curving soccer kick. Here are two ends of the spectrum.
First, there is the lower, easier to consume version from io9.com
Physics forced to come up with whole new equation to explain "impossible" soccer kick
I will summarize this article for you:
"Have you seen these crazy soccer kicks where the ball curves? It happens because the ball spins and physics. Here is a video"
Oh, and they have a diagram - which doesn't seem to come from the original paper and they also have…
drorzel | July 12, 2010I 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 did eventually find a spot at the bar in a Mexican restaurant, and managed to watch the middle portion of the game. I missed the last 15 minutes of regular time and all over the extra time because I was on a plane back to Albany.
I was planning to write up a recap of what I did see, but…
drorzel | July 6, 2010I 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 of FIFA?
I'm not as enthusiastic about today's game, which looks likely to be a dull defensive match, as tomorrow's, which ought to involve some scoring. Unless the loss of Thomas Müller to accumulated yellow cards (the last a puzzling one, given that his alleged handball was more or less…
drorzel | June 29, 2010The 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 is the immense suckitude of the refereeing, which currently accounts for at least four screwed up goals (two not allowed for the US, one for England, and an improperly allowed goal for Argentina). It's gotten to the point where FIFA is being dragged toward the Century of the Fruitbat, and might start…
drorzel | June 26, 2010The 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 universe, the teams involved would be punished with embarrassing losses in the first eleimination game; as they play each other, that's not going to happen.
Note that seven of the final sixteen teams are countries where How to Teach Physics to Your Dog has sold. Of countries who have purchased…

drorzel | June 23, 2010The 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 to advancing past group play. Meanwhile, France, where rights have not yet sold, was eliminated.
I'm also happy to report that Spanish translation rights have been sold, and a translation is in progress, so Spain can go into their final group play game without…
drorzel | June 21, 2010Three 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 to Your Dog. Meanwhile, the seven countries with current or forthcoming editions (the US, Brazil, Portugal, England, Italy, Japan, and South Korea) have a combined record of 5-2-7.
I think the lesson here is clear: translation rights for Spanish, French…
drorzel | June 20, 2010Friday'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 each other, both fell down, figuring it was about 50-50 that he would call something.
The cavalcade of cards eventually got German striker Miroslav Klose thrown out (for a nothing little tackle), so Germany spent the last hour or so of the…
drorzel | June 16, 2010So, how do things stand with the Uncertain Principles World Cup Contest at the end of the first round?
We have completed the first set of 16 group play games, and to this point, we have 6 ties. Extrapolating from that to the final result (because, of course, you always start with a linear extrapolation) you would expect a total of 24 tie games. The contest also asked for the total number of goals in the tournament, for use as a tiebreaker (since we can't make commenters do penalty kicks), and there have been 25 goals scored to date, which extrapolates to 100 for the final total.
In the naive…
drorzel | June 15, 2010We're several days into the World Cup now, and I have just about settled on my rooting strategy for countries I have no personal connection to: I'm going to root for countries where we've sold the rights for How to Teach Physics to Your Dog over countries where the rights haven't been sold yet.
This is a good strategy for producing a mix of teams-- I get to root for both Brazil and Portugal, for example, and also underdogs like Japan and South Korea-- but it has one major flaw: we've sold Italian rights. And I find it really hard to root for Italy, one of the flopping-est, whining-est,…
drorzel | June 11, 2010This was supposed to go up earlier, but it turns out that thinking you selected "Scheduled" in the MT back end is not, in fact, enough to schedule the post to appear. So this is showing up after games have already begun, but nothing of consequence has happened yet, so it's no biggie.
Anyway, the soccer World Cup has begun, making this one of the rare summers with sporting events worth watching on television. And time for the quadrennial spectacle of Americans pretending to know/care about soccer.
So, anyway, there's a big tournament going on, and it seems only fair to offer space to discuss…
drorzel | June 8, 2010Ethan Zuckerman has an excellent round-up of selection strategies for who to support in the 2010 World Cup soccer tournament. Options include strategic support, support through spite, non-FIFA support, and aesthetic considerations. A couple he left off:
Flopping Artistry: To American eyes, one of the most notable features of international soccer is the way that players dive on the ground wailing at the slightest hint of contact. Inexplicable as this is, it is evidently an essential part of the sport, so why not select teams based on their players' ability to mimic a gut-shot Tim Roth in…
drorzel | July 10, 2009If you're desperate for something to fill your Friday afternoon, and not the comment-leaving sort, you could do a lot worse than spending an hour and a half (give or take) with Chuck Klosternman and Bill Simmons in their two part ESPN podcast. It's nominally about sports, but they spend a good bit of time talking about Michael Jackson (in a sensible way, not a vapid-entertainment-reporter way), the effects of fame, the effect of writing for an audience, and a bunch of other interesting stuff.
It's about a week old, but I only got around to it yesterday. It's worth a listen, though. It also…
