C100H202, 1ns: check

Friday, April 22nd, 2005

My sim­u­la­tion code seems to be work­ing pretty solidly now and I’ve got­ten almost my entire poly­eth­yl­ene model work­ing. As of right now, I haven’t addressed bond eclips­ing and some of my inter­ac­tion con­stants are a lit­tle off but, oth­er­wise, every­thing seems qual­i­ta­tively good.

Right now I’ve got my com­puter run­ning a sin­gle C100H202 mol­e­cule at 273K. I am per­form­ing cal­cu­la­tions for every fem­tosec­ond, record­ing for every picosec­ond and it will gen­er­ate a full nanosec­ond in about 4 hours. After the cal­cu­la­tions are done, I’ll ren­der up images and make a movie, which I will prob­a­bly then post somewhere.

I’m a lit­tle dis­ap­pointed in the state of the com­pu­ta­tion engine but I don’t care; I’m just so glad that I got the model working.

UPDATE: It all worked out rea­son­ably well and I have a video up on the page that I just made up for my the­sis. Sadly, ini­tial con­di­tions and physics caused the sys­tem to develop a rota­tional mode that, com­bined with some soft­ware lim­i­ta­tions, makes most of the video rather unin­ter­est­ing. The first few sec­onds are nice. Further things will be placed on that site as they appear and will, for the most part, not be men­tioned here.

Do it and it will get done

Thursday, April 21st, 2005

I’ve been stress­ing out about my the­sis lately, namely inso­far as it not get­ting fin­ished and that I’ve been blow­ing off time that I should have spent work­ing on it but it turns out that it’s not hard to write when I actu­ally do so. I’ve spent the past 3.5 hours hun­kered down in my room and I’ve churned out 7 pages of pretty decent stuff. If I can get myself to do this in the future, every­thing will get fin­ished might fast and I can get back to slack­ing with­out stress.

The next thing that I really need to do is add some equa­tions and dia­grams to help make sense of some of what I’ve writ­ten. I also need to go do some research to get some ref­er­ences and a whole bunch of back­ground material.

As great as pro­cras­ti­nat­ing is, now is just not the time for it anymore.

CalTech doesn’t know that we don’t care

Wednesday, April 13th, 2005

It appears to be the case that CalTech is tak­ing up a prank­ing war against MIT. This reminds me of the var­i­ous col­lege rival­ries that I am aware of: CalTech has a rivalry with MIT, MIT has a rivalry with Harvard, Harvard has a rivalry with Yale and Yale has a rivalry with Harvard. Save for the Harvard/Yale rivalry, these rival­ries are one sided and the tar­get gen­er­ally doesn’t care about the insti­ga­tor. As far as I know, Harvard thinks they’re bet­ter than MIT and doesn’t care enough to bother with us and the same is true for us and CalTech.

I’m speak­ing largely from my own expe­ri­ence and it may very well be the case that CalTech may be able to inspire some MIT stu­dents to react and the rivalry may become two sided. Personally, I find it rather child­ish but I am still mildly curi­ous to see what will hap­pen with this whole affair.

Pre-counted eggs

Thursday, April 7th, 2005

It turns out that I did not get into the one grad­u­ate school that I applied to. I guess this means that I counted my eggs before they hatched, which makes it good that I’m a mam­mal and my species bears live young. This means that I am now roughly two months from free­dom and not know­ing what I’m going to be doing in the future; it’s actu­ally a kind of nice feeling.

200th and Classes

Tuesday, February 1st, 2005

Well, today is the first day of classes of my last semes­ter as an under­grad­u­ate and this is also my 200th post.

This leaves two things to dis­cuss and I’ll start with the 200th post bit. 200 posts, hooray! Ok, that’ll do for that.

So, first day of classes, I guess that I might as well give a bit of a pre­view of what this term is going to look like for me. I’ve got my sched­ule nar­rowed down to only hav­ing classes on Tuesdays and Thursdays so I intend to use this fact to work on my the­sis on Mondays and Wednesdays and get three day week­ends as well. I’ve also got a pretty nice class load­out to go with my beau­ti­ful sched­ule. I am tak­ing 3.063: Polymer Physics, 11.125: Exploring K-12 Classroom Teaching, and 21M.600: Introduction to Acting. This term is going to be totally sweet.

Application Away

Thursday, January 13th, 2005

I turned in my appli­ca­tion for grad school ear­lier today; yes, that’s sin­gu­lar. This year I am apply­ing to only one grad school and if I don’t get in I am going to go do some­thing else. That is my plan and I’m stick­ing to it.

Anyway, the appli­ca­tion is in and now I just need to worry about grad­u­at­ing. The rest of my future is out already deter­mined as far as I am concerned.

I’ve cho­sen the track that I’m going to be on and now I just need to toss coal into the fur­nace for a while.

GRE = Annoying

Thursday, October 21st, 2004

I took me some GREs today; they weren’t too bad, but they were pretty annoy­ing. It took all this time and stuff. The pos­i­tive aspects of tak­ing the GRE today is that I can go in and talk to my advi­sor and see if he thinks my scores are good enough to apply to grad schools or if I should go take some­thing again; I really don’t want to take them again, it’s expen­sive and annoy­ing. The neat part about the new com­puter based test­ing is that they give you results for Verbal and Quantitative as soon as you fin­ish. Not going to post my scores because this isn’t high school any­more but I will say that I was pleased with my Quantitative score and have mixed feel­ings about my Verbal score.

GRE be done (as long as my advi­sor agrees). George out.

The Beginning of the End

Wednesday, September 8th, 2004

It is now offi­cially the begin­ning of the end, today was the first day of the first term of my last year as an under­grad­u­ate at MIT. It’s kind of funny; wasn’t long ago that I got here and it was even more recent that they handed us our Brass Rats. It’s kind of funny how fast time flies. At this rate, I’ll be get­ting my Ph.D. before I know what’s happening.

My new office is in 7-100LA

Wednesday, February 18th, 2004

For those of you look­ing to find me dur­ing the day, my new office is now in 7-100LA. I will be adopt­ing an open door pol­icy whereby any­one can step in and visit if they would like to talk or need any­thing. I will be in my office dur­ing the week when I am not busy with prior engagements.

I hope the move poses no incon­ve­niences for anyone.

Swamped already, how can this be?

Tuesday, February 10th, 2004

It’s exactly one week into term today and, some­how, I am already com­pletely swamped. I even dropped two classes today. No time to blog more than that. Back to work.

It is now 6:13a

Tuesday, February 10th, 2004

You might be ask­ing your­self why I’m awake at this hideous time of day; heck, I might be ask­ing myself the very same ques­tion. Unfortunately, I know what the answer to the ques­tion is: class. I have an 8:30a class on Tuesdays and Thursdays this term. The prob­lem of course is that I have to go to sleep at like 10:00p on Mondays and Wednesdays but the upside is that I don’t have any­thing on Friday or in the morn­ing on Monday and Wednesday.

I guess the truth of the mat­ter is that it’s really early, I don’t have any­thing to say and I don’t want to fol­low the pre­vi­ous entry with a long pause because, despite the ironic humor, I don’t want to be that guy.

Time for another term

Monday, February 2nd, 2004

Tomorrow (today after I wake up) is reg­is­tra­tion day and then spring term classes begin Tuesday. I can’t really say how I feel about the whole new term thing; I have mixed feel­ings. On one hand, I would like to get back to learn­ing new stuff, being active and fol­low­ing a set sched­ule, but on the other hand, I know that there will be a lot of work involved.

The goal for this term is to try to have classes only on Tuesdays and Thursdays, giv­ing me four day week­ends and Wednesday off. I’m not cer­tain if it is pos­si­ble, but I’m pretty sure that it is. The only prob­lem is that it cur­rently looks like I’ll end up with classes from 8:30a to 5p, which is irri­tat­ing but won’t be too bad if it’s only twice a week. If I do get most of the week off, I’ll have to fig­ure out how I want to arrange the rest of things; do I work a lot of desk, or go out and do things, or do my home­work, or do other work, or just sit around? This will all be deter­mined later if I can pull off the two day week.

Then, of course, I will have to go and deal with one of the worst things asso­ci­ated with the begin­ning of term, fig­ur­ing out my text­book sit­u­a­tion and how much money I’m going to end up shelling out.

Oh well, it’ll be nice doing some more learning.

6.270 be done

Thursday, January 29th, 2004

6.270 has come and gone now. We didn’t win; in fact, we didn’t come any­where near win­ning. On the other hand, we did have a really good time. If it weren’t for the lack of prizes and campus-wide recog­ni­tion, I’d say it was bet­ter this way. That hav­ing been said, I’m more than plenty happy.

6.270 is nigh upon us

Monday, January 26th, 2004

6.270 qual­i­fiers and seed­ing rounds are today and impound is Wednesday. Our robot is very much not ready to actu­ally com­pete but we only need to score a few points in order to qual­ify and be allowed in the actual com­pe­ti­tion. I’m con­fi­dent that we can score enough points to qual­ify, though we will likely seed poorly (not that it really mat­ters). After that’s out of the way, it should prob­a­bly take us a few an hour or so of ded­i­cated work to get the robot com­pe­ti­tion ready (by which I mean capa­ble of win­ning). We should be plenty ready in time for impound.

All in all, despite the fact that both Muth and I have pretty much taken IAP off, I am still con­fi­dent that we’ve got this thing fig­ured out. More 6.270 news when we’re com­pe­ti­tion ready.

Mystery Hunt :: Art Gallery

Saturday, January 17th, 2004

Right now there’s this Mystery Hunt thing going on in my dorm and other MIT related places. Basically, it’s this huge puz­zle con­test of sorts. This year, once again, I have decided not to take a hugely active role in the mat­ter and have just taken a con­sult­ing sort of approach to the whole thing. As it stands, I have con­sulted on two prob­lems both of which have been solved whilst I was help­ing. The first one was some­thing involv­ing some organic mol­e­cules and what­not; other peo­ple did the grunt work and I helped with some of the end bits and get­ting the solu­tion. The sec­ond one was this really neat symmetry/crystallography one which I got involved with when some­one said, “Hey George, we have a prob­lem that we think is crys­tal­log­ra­phy, help us.” Now, on this puz­zle, I was there pretty much from start to fin­ish (minus sleep and some other things) and I played a pretty piv­otal role in solv­ing all parts of it. After all, I do know my crys­tal­log­ra­phy. Incidentally, we were the first team to solve the symmetry/crystallography puz­zle and the orga­niz­ers expect that we may be the only team that will solve it.

w00t!

Muth and I pwnz

Friday, January 9th, 2004

Muth and I are work­ing on this 6.270 robot of ours and get­ting good results. Mind you we’re not work­ing on our com­pe­ti­tion robot yet, just one to com­plete the var­i­ous assign­ments for the class before we can start work­ing on our real robot. This being totally unim­por­tant quality-wise, we’ve been shoot­ing for just enough effort to get things checked off and move on. Assignment 3 was due yes­ter­day and Assignment 4 today; these are the only assign­ments that involve our pre-competition robot.

Assignment 3 invovled build­ing a robot that can go for­ward, back­ward, turn counter-clockwise and respond to a bump sen­sor. Yesterday we spent 2 hours build­ing a robot that sat­is­fied the require­ments for Assignment 3 and most of the time was spent debug­ging code only to find out that I had for­got­ten how to tell the dif­fer­ence between left and right. Having fin­ished, we walked into lab and were checked off in about 10 minutes.

Assignment 4 is where the story gets fun. Assignment 4 was to make your robot chase after an IR Beacon. We start out oday with some mod­i­fi­ca­tions to our robot from yes­ter­day, namely mount­ing the IR Beacon and fig­ur­ing out how to make it work (which is pretty hard because it’s sup­posed to be con­nected to the expan­sion board, which we aren’t using). So we ended up putting about 1.5 hours of work into the thing (of which a por­tion was taken up by my mak­ing and eat­ing some mac­a­roni and cheese). We didn’t test the robot before going into lab and my expec­ta­tion was that it would be suf­fi­cient, but barely so, to pass check­off. So we go in to lab and I’m think­ing that I should prob­a­bly test the IR recog­ni­tion capa­bil­i­ties of the robot before we ask to be checked off (don’t want to waste TA time after all), but then I fig­ure that I don’t really care and it should work so I don’t bother. We’re stand­ing there wait­ing to get our hands on another IR Beacon so that we can try our robot and in the mean­while we watch a num­ber of other teams make robots that sit there and twitch a bit, maybe twitch­ing gen­er­ally towards the IR Beacon and so on. We get tired of wait­ing so we ask if we can just get checked off then (with­out both­er­ing to test) and our robot races after the Beacon so fast that the guy can’t get away from it fast enough. The thing is flaw­less, and the TA made the remark that, “That’s the way it’s sup­posed to work.” So basi­cally, with a total of maybe 3.5 hours of work Muth and I have man­aged to make one of the best robots for Assignment 4.

6.270’s a’ happenin’

Tuesday, January 6th, 2004

So, I’m doing this here 6.270 — Autonomous Robot Design Competition as my thing this IAP. To sum it up in a brief lit­tle chunk, basi­cally, a lot of peo­ple make some robots out of Lego and con­trol them using these Handyboard things, which are just fancy lit­tle con­trol boards that let you make sim­ple robots. All of the robots (60 teams worth) will then be pit­ted against each other in a set of qual­i­fy­ing rounds and then a big dou­ble elim­i­na­tion competition.

Now, that the cur­sory expla­na­tion for those out of the loop is done, some other details. My team con­sists of myself and that Muth kid. Muth’s a good kid; I like him and I think that we’ll man­age to do pretty damned well with this com­pe­ti­tion thing. We’ve already fig­ured out our strat­egy for try­ing to win and it seems pretty solid and more impor­tantly, sim­ple. Since we’ve got a good hold on what we’re going to be doing and how we’re going to do it, we’ve taken up being a bit arro­gant, but I think that it’s not totally unfounded. Following are some of the amus­ing things that exem­plify this arrogance:

  • Planning to be done 1 – 2 weeks before the competition
  • Planning to sit around get­ting wasted while every­one is fran­ti­cally try­ing to make theirs work when the dead­line is upon them
  • Fielding a placebo robot for qualifiers
  • Naming our robot “# Awesome”, where # is the num­ber of points that we will be earn­ing in every round.
  • Not using the extra batteries
  • Not using the expan­sion board

Anyway, the list con­tin­ues, but the basic point is that we think that we’ve got this com­pe­ti­tion in the bag and we’re going to be jack­asses about it. It will be pretty damned fun to be bet­ter than the rest of MIT and lord it over them. Admittedly, if we fuck up, then we’re just a pair of idiot jerks, but I don’t think that’s going to happen.
