4:54 pm - The Uncertainty principle
How I look at the world, then... let's start at the beginning and look at how we look at the world. The first thing to note is that the world is perceived. Without diving into any detailed mechanics of the perception process, the first thing to note is the gap between the inside and the outside. Inside, we have representations. A starting point for those has to be taken as given, as something arising from what is hard-wired. As we observe, we update those representations.

I think it is vital to realize that these representations are simplifications and abstractions of what, for lack of a better term, is 'real'. We can be very serious about science, but 99.9% of everything that is relevant to us cannot be captured in theories (which, themselves are models rather than facts or anything that has a one-to-one correspondence to what is real).

So the main thing that stands out is that in the end we don't know, and of necessity we create highly fictitious models (of which we often know very well that they do not in any way have the shape of anything actual). In other words.. in a world far too complex for us to truly understand, most of our day to day activity is to take in new tidbits and somehow weave a connecting story around them.

The vast majority of our conceptual world is highly unreal when you look at the details. It's just that we find these untruths to be quite useful in determining what a successful next action might be--rightly or wrongly.

1:42 pm - Journal direction
I just noticed that the last couple of entries were marked "friends only" for no good reason. I think I opted to hide entries that touched on "work" to keep this a purely "life" blog, but there is no reason to go overboard with that and not even show how I am doing generally. So that is fixed now.

Technically, I have four on-line journals at the moment, none of them very active. I think I may use this one to write some more about how I look at the world in future. Then again.. I find that journals never develop in expected ways, so.. we'll see.

9:04 pm - Update
To summarize the last couple of quarters: Q2 was indeed a bit more relaxed, but Q3 wasn't. My administration still isn't caught up, and it probably will be quite a bit longer before it is. I am looking to ensure that next year will be a bit less busy than this year was.

One major trend worth highlighting is that I seem to be shifting substantially into the direction of being more open about myself. It would probably be true to say that my privacy concerns are taking more of a backseat now. I am not sure if that is necessarily a good thing, but my sense is that we are going to move into a network society more and more whether I like it or not, anyway.

Over the last few quarters I have also developed an impression of generation Y being rather self-absorbed.

10:29 am - Mini-update
The previous couple of months work had been claiming too much of my time, but that is normalizing again now. I guess the preceding period can be characterized as "work hard, play hard" to the max. I seem to be playing more than I used to now.. in part with the Wii we acquired after I found that it was pretty much fun. For some reason I seem to be doing fitness exercises now, too, which is a bit of a novelty..

My music lessons are progressing to satisfaction. I am also feeling settled in a bit more. I still have an administrative backlog that may take a couple more quarters to clear up. But overall I am doing fine, I just should get a little more sleep on average over the next couple of months..

current mood: relaxed

12:05 am - New community
As you may remember I have been rather interested in the Myers-Briggs Type Indicator (MBTI), and involved in communities for it on LJ, though I have not found the time to really expand on the subject as much as I would have liked, as illustrated by this entry. I may come to focus on it more in the newly founded rationals community that I will be co-moderating.

current mood: calm

I realize it has been more than six weeks since the last update. Not that I haven't been posting (actually, I posted several dozen messages to communities and other people's private journals), but... well, not about me.

So this is what happenedCollapse )

11:20 pm - New picture
Well, I recall I said I would try to replace the previous user picture before it was two years old. As you have seen, that didn't actually happen. It would in fact still have been on here, if I hadn't been surprised by a fairly nice picture in the company newsletter I had actually forgotten was shot when I handed out the table tennis trophies for our competition. But I was, and I decided it was decent enough to cut a user picture from, so... enjoy! :-)
