Computer Problems and an Interesting Dinner

by rrusczyk, Jun 17, 2006, 3:21 PM

Ness and I flew across country today to DC, where I will be attending an AMC Board meeting tomorrow and Saturday. Looking forward to seeing some old friends like Harold Reiter (who got me back into math education a couple years ago), and meeting some people I've emailed with or talked to on the phone like Susan Schwartz Wildstrom, Dick Gibbs, Elgin Johnston, and others involved with the AMC. I'm very curious to find out more about how the AMC works.

As for the computer problems, for the past day and a half we haven't received any online orders. Today I found out why - our credit card clearing company changed its processing software . . . without telling us :mad: . DPatrick and MCrawford sorted it out, fortunately. It's amazing how many little things can go wrong, sigh.

Tonight we had dinner with Steve Olson, who has written a couple very interesting books. One of interest to our readers is Count Down, about the 2001 IMO team. I highly recommend it. One of our AoPSers, joml88, tells me that reading about how the IMO students approached problems helped him approach this year's AIME (which he notched an excellent 11 on, so it worked). His first book, Mapping Human History, was a finalist for the National Book Award (and is also fascinating for those interested in life sciences).

Steve has a degree in physics and is now a nonfiction writer who focuses on scientific areas. He even has a scientific research paper coming out in Nature soon involving (as I understand it - I'm looking forward to seeing the paper) an application of graph theory to genomics. There aren't too many nonfiction writers making new contributions to math and science, but Steve shows it can be done. Those of you interested in both fields might take note.

We spent much of the time talking about extracurricular math education, including discussing a conference Steve, Vanessa, and I attended at Berkeley last December. The conference ostensibly was about Math Contests and Math Circles. Steve came away with the same question I had going in - 'What was the goal of the conference?' I felt like a lot of the academic world doesn't understand what's going on in classrooms or in middle/high schoolers' lives (not that I do entirely understand it, but I think I'm a lot closer than the average professor at an elite school). Further, I felt that some missed the point of math contests and math circles. Some seemed to construe the goal as 'make more mathematicians'. With this, I strongly disagree - the goal I think is to help people learn how to reason and solve problems more effectively. Math is just the best tool to teach it. If they don't become mathematicians, all the better - we need thinkers everywhere.

On the flip side, I don't think I fully understood (or yet understand) the environment professors live in. They seem to talk about education as something that shouldn't be about money, yet spend an awful lot of time talking about tenure (i.e. guaranteed paycheck) and grants (i.e. money). Again, this isn't a universal complaint - many of the professors there were like Paul Zeitz, very much involved and large contributors to middle and high school education, without any glimmer of 'tenure' or 'grants' shading his focus on education. But I did start to more clearly understand the complaints my father (and many, many others) has about the blinders worn by many in academia. It is very much a different world than the one I work in. It is yet another 'Road not taken' for me - I abandoned that two months into grad school. I don't regret it. I think I'm simply too impatient for that to have been a good environment for me.

Looks like your link for Count Down didn't work.

As someone who will almost certainly travel down that road that you did not, I am curious about your last sentence. What's there to be impatient about with respect to academia? I suppose that my impatience makes it impossible for me not to go into academia -- I need to learn everything, and it can't wait another 10 minutes to do so.

I was at the conference as well. I'm just a college student and not one who's done spectacularly well on contests or anything like that, but I'll put in my two cents.

My understanding was that the MSRI's interest in grade school enrichment IS largely the prospect of nurturing future mathematicans. It's arguable that the organization should be more interested in general outreach activities independently of whether it helps the field itself, but given that the organization is heavily grounded in research math such an interest is perhaps not surprising.

On a related note, I think that there is something to be said for activities more closely associated with research math than contest math being beneficial to all sorts of people. There's definitely a lot more to math than being given a series of problem to the effect of "Suppose A satisfies X, Y and Z , prove that ....." and solving it. Sure, that type of thing can involve an immense amount of sophisticated thinking, but there are vast expanses of mathematical territory that aren't touched by solving such problems.

I'm thinking of things like realizing the need for greater rigor in a holistic sense ala Real Analysis. (For example, noticing that while at first it might seem like it's okay to prove the Cauchy Schwartz inequality in n dimensions by saying that dot product is product of magnitudes times cosine of included angle, with some thought realizing that such a proof presumes a notion of angle in n dimensional space which turns out to need to be defined in terms of dot product and that the justification for angle being well defined IS the Cauchy Schwartz inequality, and that while it at first seems like it might be possible to patch the issue up by projecting the plane with the two vectors onto R^2 the issue is more messy than it might seem at first because such an attempt uses the idea of an angle preserving transformation which is impossible to define without a notion of angle to begin with).

The other thing that I was thinking of was the development of aesthetic preference for certain problems and ideas over others. Some of the ideas present in the contest problem lore are more interesting than others. Of course, everyone has the opportunity to think about his or her preferences, but when you train for an olympiad you have to know X and you have to know Y and you have to know Z and you have to have a lot of practice with problems of all types, etc. There's not necessarily a lot of time to stop and think about if and why a certain problem is interesting and how the result might be generalized. It's not discouraged and does take place, but it's not explictly encouraged either.

Doing research like activity in which one poses her own questions, creates her own definitions, decides which questions are fundamental and which are just curiousities, etc. is qualitatively different from olympiad problem solving. I think that there is something of value to this other side of math that most high schoolers don't get to see. Of course, doing research can be slow and perhaps less thrilling, but I think that it would be good if more people could at least be exposed to the concept in a user friendly context. Part of the reason for this is aesthetic - there are matters of much interest in all different parts of math.

Moreover, I don't think that it's at all clear that the pure problem solving part is really the part that is applicable to industry jobs and real world problems. On the contrary, I think that crossover intellectual training gained from math is gleaned from all aspects of math; perhaps not in a direct and obvious way but in the long run.

I think that some people the conference were coming at least in part from the point of view that I expressed above, would be curious as to your response.

My comment about patience was simply one of personal preference - I lack the patience for long-term research. I'm not saying such research is without value, just that it is not part of my personality. On the other side of the coin, those who wish to know for the sake of knowing and are willing to spend years in order to know, do indeed have the patience I lack to pursue research. I'm more interested in doing and creating, and don't have the patience to view a 15-year project in that time horizon. Complex, don't you worry, you are going to be a fantastic contributor to academia. You are impatient to know. I am impatient to do, to produce tangible results that affect others in the short-term. Therefore, you will be very happy in research academia. I, however, will find my home elsewhere.

My comments regarding the point of mathematics competitions and problem solving were not intended to say that producing mathematicians is not a lofty goal; they are intended to say that it is not the only goal. Further, I don't think producing mathematicians is even the most important goal of these contests, which was distinctly the attitude of some of the conference attendees. (In fact, I don't think it's even an important goal - the world is not hurting for lack of mathematicians.)

As for problem-solving skills being applicable to real world problems and industry, we may have to agree to disagree. I find fundamental problem-solving skills far more applicable to what I do now, and what I did at DE Shaw, than I do/did any higher mathematics. Most people, even those in technical jobs, use little higher mathematics. They solve problems all the time. This may, however, be a semantic disagreement - you may be defining 'mathematics' as I define 'problem solving', and you may be defining 'problem solving' as 'contests'.

I do, of course, agree that there's much more room for more interesting contests, and exploration as you suggest. Finding and defining the interesting problems is extremely important. If extracurricular programs could address this more completely (and not just to those who have access to a professor or parent to help them, as is the current case for the most part), this would be fantastic. But I will note that while there's not much time during contests to stop and think why one thing leads to another, all successful problem solvers will probably tell you that they did indeed wonder this, and addressed it after the contest (or better yet, before it). That's life - in many disciplines, you do have to make decisions and then ruminate later about how to handle them if they come up again.

As for research being less thrilling, that's in the eye of the beholder. This really is a matter of personal preference. Complex, for example, will find it far more interesting than building educational resources or trading bonds, both of which I found eminently more interesting than research. Like I feel about airplane pilots, judges, policemen, and a host of other professions, I'm glad there are researchers, I'm simply not one of them.
