Alumni Email

Friday, August 8th, 2008

When I left Dartmouth, I set up my alumni email and then promptly forgot about it until today. This is a bit of an apology for not replying to the 125 messages that you all have sent to me over the last 2 years. Whoopsie.

  

Play MarioKart, ace Med School

Tuesday, August 5th, 2008

Well, they don’t say what games are being played, but lazy students have a new excuse in their arsenal now that surgical residents in a Phoenix AZ hospital are now being required to play Wii games as part of their training.

Q: Can a video game really help somebody improve as a surgeon?

Smith: We used cyber gloves which computerize hand movements of surgeons and we put those on surgeons. We have data on that. We put them on people playing the Wii. There is a very, very high correlation between the two and this is documented statistically.

I remember reading earlier this year an article on how marble madness was a particularly good training exercise for fine motor control - to noone’s real surprise. Those clever little accelerometers.

  

Can you help me with statistics?

Friday, July 25th, 2008

I have a statistics question that I need some help with. It’s really a question of “what is the statistical importance of a deviation from a fit?”

Let me illustrate with plots:

1. Here we have some data and a line fit to the data. Everyone I’m sure agrees that this is a good fit.

2. Now, the same data and fit, but with one point that’s off by 1-sigma. 1-sigma events happen all the time (well, roughly 1/3 of the time) so we’d still assume that the fit matches the data well.

3. Now we have a point that’s 2-sigma from the fit. Assuming a normal distribution, that should only happen by chance ~5% of the time, so we start wondering if the deviation of that point is actually a significant event.

4. Now, the real question. Instead of a single deviant point, we have two points. Both of them are 1.3-sigma from the fit. If taken individually, there’s a ~20% probability that each one does match the fit. However, we “know” that they’re correlated in that the depression of both points is related to something physically going on. How would I determine how statistically significant this depression is?

Needless to say, my real data isn’t faked and is more complex than the example, but I need to figure out the same sort of answer. I’d appreciate any help that anyone can offer. And I apologize for using my astronomer’s imprecise statistical descriptions.

Memorial Day thoughts

Tuesday, May 27th, 2008

So, yesterday was the first time that I didn’t go to work on Memorial Day in a long long time, if ever.  In fact, I wasn’t allowed to go to work (well, not go and get paid for it).  While I appreciate the taking of a day to honor those who have served our country and paid with their lives, I’m not entirely comfortable with how the “day off” has turned into a day of beer and grilling and baseball, much as I like those things.

This NYT article echoes this sentiment and provides a bit of history of the holiday, for those interested.

Having not served in the Armed Forces, I feel like I need to be careful, but my personal feeling about Memorial Day is that I’m not comfortable just not showing up for work, hosting a party, getting misty-eyed during the national anthem shown on TV before the game, but that’s about it.  We as a nation do a shitty enough job taking care of those veterans who make it back with a heartbeat - I think those that don’t deserve a bit more remembrance, y’know?  On the East Coast I would always try to make it down to DC to visit the Vietnam Wall for Remembrance/Memorial Day; somehow that seems more appropriate.

That said, were I to number among the fallen, I would want my kids, wife, family and friends to have the day off and have a good time, maybe place some flowers on my grave while on their way to take in a minor league baseball game.  Hmm, that sounded a bit morbid, but I think the sentiment is clear.

  

Ca$h back

So, even though the major credit card companies do not  concede any wrongdoing, a class-action lawsuit against them is in its final stages, which means that you have ~10 days left to claim $$ from them.

This stems from the foreign currency fees charged by Visa/Mastercard/etc, so click here if you used your credit card overseas between 1996 and 2006.   I haven’t finished it yet -updates today or tomorrow, but I am told that the best way is to call first and get a claim number, then finish it up online.  (But it has to be done/completed by May 30th!)

There are three different options: if you didn’t travel much, then you just get $25.  Or you can total up your time spent abroad, or if you spent a lot and have absurdly good records, you can enter the amount that you spent abroad.

  

Aurora Borealis Gets Served:

Friday, May 9th, 2008

A recent quote from The Superficial:

“… It was sort of magical, you know? Like seeing the Aurora Borealis. Or, no, wait, that’s bush league. I got it: A really awesome chicken wing shaped like Abe Lincoln that you try to tip a stripper with. Swish! Count it! Northern Lights, you just got served.”

It hurts having my research be so degraded… Then again, maybe the rest of the post makes up for it.
