memory

So, my office moved to the other side of the building a month or two ago. My lab is still over there near my old office, and that's also where the copier room is, and the kitchen where I get hot water to drink. So, I do still go over there frequently.

One thing I don't do over there so frequently is use the bathroom - there are two restrooms near the new office, so now I usually go there. These two restrooms are both unisex, and are next door to eachother, and are basically mirror images in layout. The old restroom is laid out differently.

So, just a few minutes ago, I go to the kitchen to get some water, set my mug on the coffee maker to wait for me, and go into the old restroom. This whole time, I'm thinking about the talk that Shrinivas gave a little while before. I do my quick business in the restroom, turn around to leave - and realize that something is wrong. I don't recognize my surroundings. I don't know where I am.

At first, it was kind of terrifying - I thought that I didn't know where I was at all, but quickly realized that, really, I just didn't know which bathroom I was in. The lighting, i.e. the color temperature, was unfamiliar. The layout seemed wrong. "Which one am I in?" I thought. "The left one or the right one?"

I stood there for a few seconds, and thought hard about what was wrong, then finally figured it out. I remembered the water, and that I must be in the old restroom.

That makes two times now that I was in that restroom and thought I was having a stroke. First time was the first time I had experienced a visual migraine aura, which was much more awesome than this.

1k/mo

Got over 1000 page views for the month of august, basically because last week was HUGE for my classic comedic dialogues and self-indulgent essays. No no no, really, it was MS-WBT server. Observe:
Yeah, I don't know what's going on. Whatever it is that causes people to google "MS-WBT server", and wind up here for a few seconds, got a little worse last week - visits increased by something like 30%. Google is weird, the internet is weird, MS-WBT server is weird.

Going to Nashville tonight!

self

I have been thinking frequently about who I am, and about whether who I am has changed over the years, and if so, how.

One thing I keep returning to is this feeling that I am losing myself, or that my self is somehow diminishing over time. What I mean is, I feel more and more that I am what I do, and what I see and feel, and the people I interact with - mainly Jingping (not that I think I am Jingping, no) - and the random thoughts that run through my mind when I'm away from things to do or people to interact with.

This isn't necessarily a problem. I don't mind being my thoughts, or being an interaction with my wife, or being the work that I do, or the procrastination that I put between myself and my work. These things, or parallel things, are what I think we all are. But parceling your self into these discrete components makes them identifiable, and subject to direct analysis, which can reveal things in stark detail that you realize you just don't like. There are some specific features that bother me.

When I was younger, I spent a large portion of my free time writing. I wrote stories, essays on my thinking, letters, etc. I did this because I wanted to. Now, I write because I have to - I do research, and I have to write about it to sustain my personal profession. There is always work to do, and when I feel willing to write, I feel I have to apply this will to work, not fun. So, I almost never write for fun anymore. Even worse, I realize that I distract myself from this sort of unease by reading what others have written. It's as though I'm replacing parts of myself with parts of other people.

Also, over the years, I more and more began to think of my self expression as excessive, or pretentious, or useless, and so I suppressed it. I think that my entire character is suppressed. This has not had the result of simply bottling up my character, but instead I think that in some ways I am withering away - I feel that even if I tried to go back to my old ways, of writing out my thoughts regularly, there would be less to write. This is why I am writing this entry, which even as I write it feels excessive, pretentious, and useless. I feel like I have to get a ball rolling, though.

Another thing that bothers me is what I think about. We all have recurring thoughts that irritate us, things that we don't want to think about but that we do anyways. Some of these things are fine at a high level, because they are features of our lives. But other things - news, politics, etc., I find myself repeatedly going through these internal monologues, not daily but frequently, on topics like the American military, US history, religion, politics. Why? I tell myself that I don't care about these things, or I try not to care - I have no effect on them, and they seem to have no effect on me. I feel infected. I want to think about my life, my wife, my work, about things I enjoy. I'm not a politician or a columnist - why do I obsess over these sorts of things? I have not figured this out. I do get a strong feeling that these sorts of thoughts erode my self - they are not me, they are other people, other places. They make me forget who I am.

I am not bothered by thinking about sex or violence, or obsessing about the aesthetics of the Green Line tunnels, or wanting to see if someone sent me an email or a Facebook message, or my shabby piano playing. These are aspects of my life, they are fine in themselves - some of these things may specifically implicate odd aspects of my personality, but so what?

Conclusions: I still exist, but I have doubts about the vitality of my existence. I have suppressed myself too much, and the empty spaces in my mind are more and more taken up with irrelevant puzzles. I'm thinking that a solution may be to do something like this regularly, do more writing for fun, try to be more expressive with other people, stop always trying to hide myself from the outside.

hypothetical question

Okay, so let's say you run the following experiment:

You want to compare different states of adaptation. The yardstick you're going to use to compare them is is a matching function. You have two stimuli, x and y, and you're going to assume that the associated matching function - your matching function model - is simple, like y = mx + b. You want to know how those function parameters, m and b, vary when the adaptation state changes.

To do the experiment, you keep one adaptation state constant in all conditions. You can do this because you have two stimuli, and you can adapt them separately. So, you have two adaptors, X and Y. You keep adaptor X the same in all conditions, but you vary adaptor Y. Since X doesn't change, you can then compare the effects of Y across conditions. Adaptor X is your baseline.

Within a subject, this design is fine. You can take your xy data from different X conditions and plot them on the same axes. You look at how the data for X1 differs from X2, for example. You fit your model to the X1 and X2 data, and find that mX1 is higher than mX2. You repeat the experiment with another subject and find the same pattern - the m values are different across subjects, but you see the same relative difference between mX1 and mX2 for every subject you test. You average the results together to show that mX1 is higher than mX2. This constitutes a result of your study.

But then...

You start to look at the individual data, at how the m values vary so much across individual subjects, but that within-subject difference is always there. You think, something is covarying between these two things, what could it be? Why is it that whatever value mX2 takes for a particular subject, mX1 is always higher?

Then you realize: Y. mX1 and mX2 might not vary at all, at least not to the extent that they appear to. Maybe its mY that's varying.

Look at that model from the point of view of Y. Then you have x = (mY)y + (bY). Turn it around, and you get y = (1/(mY))x + (bY)/(mY). This means that mX is inversely proportional to mY, so that measured values of mX1 and mX2 will be similarly affected by differences, across individual subjects, in the value of mY.

Well, this led somewhere, anyways.
