Back to School

The secret's out (i.e. my boss has been told), so it's safe to post this to a public place - i'm going back to school! i'll be starting a Master's program in Statistics this fall at Portland State University. i've been feeling like the math in my life has been sorely lacking lately, so i'm very excited about this. My goal is to get a job doing analysis for a sports team. Even if that doesn't work out, though, i'm sure i'll enjoy the next couple of years and come out with the ability to find a job that i can enjoy.

There is one caveat - i need to pass an advanced calculus course this summer with a B or better. Michelle and i are of the opinion that 'Advanced' should be reserved for things other than the description of this course, but that could just be Caltech talking. Regardless, it will probably be good to get back in the swing of things with a course like this - i really haven't done calculus in 7 years.

Michelle has been awesome throughout this whole thing - very supportive and encouraging of a big career change while raising a child. i definitely would not even be thinking of doing this if she were not behind me 110% (just kidding - 100%. i don't believe in 110%).

Can anyone explain the following sentence to me?

He was the algorithm that was supposed to make the Celtics a mathematically impossible team to solve.

i just can't parse it.

No Throw-Away Questions

i don't know if you feel this way, but i am often faced with the realization that, for me, there are no throw-away questions. That is, whenever someone asks what would normally be a rhetorical question, i feel compelled to try to answer it, even if only to myself. As an example, i was recently with some friends, one of which is one of seven brothers in his family (no sisters). Another friend said, "Wow, what are the odds of that?" i'm pretty sure he just meant that seven children of one gender is a rare occurrence, and worth noting. My brain, however, had to answer the question:

Well, as long as we accept that the probability for a boy is 50%, then the probability of having seven boys (given that you are having seven children) is 1/2^7, which is 1/128, or a little less than 1%. If the question was asking what the odds are that all the children were the same gender, boy or girl, than that increases the probability to 1/64, or less than 2%. Of course, the question could also be, "What are the odds of meeting someone who is one of seven brothers with no sisters?" In that case, you'd need to know the distribution of family size... Or i could just assume that the question meant, "What are the odds that our friend is one of seven brothers?" That's easy! 100% That's my final answer.

Thankfully, i've trained myself so that this conversation is internal and not released on the general public (for the most part - i do know some people who would be exposed to those thoughts (my wife, for one - i'm so grateful for a nerdy wife!)). i've also trained myself on some elements of social etiquette. When i pass someone in the hall at work and they ask me how i'm doing, i just say, "Good." and that's that, rather than thinking for 10 seconds and then telling them how i'm really doing. i have come to understand that they don't actually want to know how i'm doing. Unfortunately (and this happens almost every time), five seconds after we've had our short pseudo-conversation, i remember that the other half of said social discourse is that i ask them how they're doing. By that time it's too late, so i leave everyone thinking (correctly) that i'm only half way to courteous. My problem is that i don't really care how they're doing. Or rather, i don't care to spend time stopping in a hallway to hear how they're doing (i usually would be glad to listen to them if they really wanted to tell me about their life). So i don't ask, and it's only after we're separated by a good 5 meters that i realize that i should have asked anyway. Really, this happens at least 90% of the time. Is there something wrong with me (short answer - yes)?

i think that's why i've had so much trouble in the past with small talk. i have trouble translating the fact that i desire a relationship with a person into a desire to talk about random topics. i'm actually much better now than i used to be - i don't mind a small dose of small talk, but i'm still bad at generating it myself. i now enjoy a good conversation with my friends, even the parts that are small talk-y, because i value their thoughts and their relationships. i still have a hard time with people i don't know as well, though. Does anyone else have this problem?

ThursdayTriptych - RPG edition

So perhaps the reverse triptych is a little bit too hard (at least for Tom Hanks movies - it would probably be easier with a larger set to choose from, like Asimov books). As it was, Tim might want to rethink his priorities, according to the amount of time he spent figuring it out. After days of work, he came up with War, Romance and Travel as his themes. Also, he gets crazy bonus points for admitting to the use of Excel. Congratulations Tim! You can see the rules here. This week (or week.5) we'll return to the regular format. Your themes are Assassins, Thieves and Warriors. Feel free to interpret liberally. Good luck!

Tuesday Triptych - Reverse edition

i took a couple of weeks off for the holidays, but i'm not completely abandoning this site. For the last challenge, i couldn't even come up with a good list, so congrats to both my brother and the dreamy accessorizer. You can see the rules here. This week i'm going to try something different. Instead of giving you the categories, i'm going to give you a set from which you must come up with the most cohesive triptych that can be filled from in the set. For this week, you must come up with themes for movies which have featured Tom Hanks. Good luck!

Tim, you should be able to add your web address in again in the comment form. Let me know if you still can't.
