Courtesy dbwilldo Right off the bat, let me say that this study was conducted by a female. And she asks a very interesting, and maybe stereotypical, question. Please read this full post before you jump to any conclusions. Or jump on me for posting this.
Do girls really "throw like girls?"
It's standard trash talk one male can hurl at another male who doesn't exhibit the form and proficiency of throwing that's usually expected. But professor Janet Hyde at the University of Wisconsin has data to back up the fact that men throw significantly farther and harder than women.
She actually has studied a variety of gender differences in her research. And the differences in throwing are one of the only categories where those gender differences are off the charts. You can read a full story about it right here.
To summarize, girls under teenage throw 51 to 69 percent the distance of their male peers. The differences grow as people get older. Teenage girls, on average, throw only 39 percent as far as teenage boys – throwing a ball for distance about 75 feet compared to 192 feet by males.
There is acknowledgement of the fact that boys in general get more practice in throwing based on the activities that they typically do compared to girls. But are there other factors.
Click the link to see some interesting theories about how evolution may have a role in this, leading to physiological differences between the muscles and movement patterns of males and females. Interestingly, the gap exists, but is narrower, between males and females in less advanced cultures.
Should we even be talking about this? Some think pointing out these differences might make girls give up hope on trying to improve their throwing. Others think data like this helps identify the difference and give girls, teachers and coaches information on how to improve. What do you think?
Of course, all these numbers still can't explain why Pee Wee Herman continues to throw like a girl.

Did you watch Usain Bolt's gold-medal run Sunday night? Check this New York Times interactive display that "charts" a race between all Olympic 100-meter medalists over the past 116 years. How much has one of the ultimate human performance measures improved over that time? What factors have made humans get so much faster over that time?
Get out there, if you can, and watch skaters take on the insane Red Bull Crashed Ice course here in downtown St. Paul. It's a great place to watch all sorts of physics in action. And bundle up. Winter's back, suddenly, and the laws of thermodynamics apply to you, too.

It's the eve of the big event – March Madness kicks off tomorrow and hoops junkies like myself will be in heaven for three weeks. But what about academics junkies? For the fifth straight year, a college organization has run the NCAA men's basketball brackets through the academic wringer, advancing schools through the brackets based on a formula of classroom success for each school. The school with the more success advances through each round of the brackets. Past editions of the challenge have produced academic champions such as Bucknell, Holy Cross and Davidson. Last year, however, the academic and hoops championship teams were one and the same: North Carolina. Who wins this year's academic bracket challenge? You have to click here to find out. I will tell you that it's not my alma mater, Mankato State.
From the loud chants coming from students for their favorite sports athletes in 1883, to the high extent of the first Liberty (stunt) in 1976. Cheer leading has went from loud chants to extreme stunts, which has increased the risk of injury. The increased risk for injury has came from the change in activity being done in cheer leading, because now they are starting to use more gymnastic like stunts which require a trained & stunt certified coaches. Without that the injury rates continue to increase.Cheer leading is the most dangerous female sport. The injuries range from fractures,broken bones, paralysis, & even sometimes death. It only takes one mistake to change someones life, so why not prevent it by taking every precaution to ensure safety & maintain all physical abilities. This teenage cheerleader suffered the pain due to the mistake of her teammates.I think there should be a regulation that prohibits bending the rules & regulations for cheer leading stunts because some coaches tend to bend them & that's how people get hurt. There should be rule that there needs to be more than two spotters because anything can happen.I personally stand by those who say cheer leading is more dangerous than football. Where do you stand? How is cheer leading a part of physics?Would you EVER take that risk of being thrown in the air?cheer or no cheer?
Philadelphia Phillies' second-baseman Eric Brunlett made an amazing and unassisted game-ending triple play against the New York Mets. The extremely rare play came in the ninth inning with the Mets trailing by two runs but threatening with runners on first and second base and no outs. Both base runners were stealing on a 2-2 pitch when the Mets batter hit a line drive right to Brunlett, who caught the ball for the first out, stepped on second base for the second out, then tagged out the runner from first. It's only the 15th unassisted triple play in major league history, and only the second to end a game. The poor Mets. The odds of this happening must be astronomical, but I'll let someone else figure that out.
Courtesy PSUMark2006Since Science Buzz is about the only Minnesota information source that has not had an item in recent days about new Viking quarterback Brett Favre, I'm going to change that and post this video of Favre speaking about the mysteries of rotator cuff injuries, evidently something he's been dealing with a lot longer than anyone knew.
With the latest thrashing by the Devil Rays -> are the Boston Red Sox showing that the statistically better team can always be eliminated by a "hot" team?
a) Yes - win streaks are more powerful than long term stats
b) No - Long term statistics should be the deciding factor of the contests
c) Neither -> head to head is the only way to decide who is the best team
Is it possible to calculate the "potential energy" of a particular Offensive line compared to a particular Defensive line?
Should a Coach know if they are statistically unable to force the line of scrimmage the direction they want?
Sure - weaknesses can be exploited by double teaming, and running slant plays.....checking the stats on each lineman the coach should be able to choose their strategy before the game....and give the best chance of success
