## Blog hiatus explanation

I do not post here very much, do I? In my defense, I have been posting:

- At the PhilTeX blog I mentioned
- At the TeX.stackexchange blog
- And at this philosophy of science blog

So I’ve not been slacking. Oh I’ve also had that whole “thesis” thing I’m supposed to be working on. I’ve nearly finished working on a paper about imprecise probabilities and decision making. It still needs some work, but once it’s out of the way, I hope to spend a little time working on the disagreement thing I mentioned in my last post…

## The start of something beautiful

Today is the official launch of my website! It took a looming essay deadline to motivate me into the epic procrastination that was this weekend. The links section isn’t working, I haven’t configured the stats things yet, and I haven’t migrated this blog over to its new home, but all that is stuff that I haven’t got time to do at the moment; I actually need to get back to writing my essay now…

Please notice the random quote generator in the footer – it took quite a while to get right… I’m afraid it’s a little too subtle and people might not notice it.

## Philosophy and classic arcade games

In my LaTeX files, I leave myself notes about bits I still need to write. Sometimes they are fairly mundane: “Weyl/Klein on locally Euclidean.” But ocasionally I leave myself a note that makes me laugh when I go back to find out what I still need to do. The note in question was “Giaquinto pacman triangle.” For a good few minutes this meant as little to me as it probably does to you now. I flicked through the book in question (Marcus Giaquinto’s *Visual thinking in mathematics*) and found what I was talking about. They do indeed look like Pacmans (Pacmen?)…

Just below this is another note which just says “triangles vs space… asteroids?” I still haven’t worked out what I meant by that one. Perhaps I was thinking of having my whole essay structure based around different classic arcade games. It must have been a long day…

## We are all going to explode tomorrow.

Today’s Guardian had a cool little special section about CERN. It is available here. I now have a false colour bubble chamber image as my desktop background. So the LHC hasn’t blown us all up yet, which is nice. If it ever does, I might feel the tiniest bit responsible, since I’m signed up to the LHC BOINC project…

In other news, the nine-point circle is my favourite fact about triangles. I will try and mention it and its relation to incircles and excircles in my dissertation. Hopefully with gratuitous use of diagrams drawn in Kig. If I can be bothered to learn how to get pictures to work in LaTeX… Another thing I’d like to do is learn how to write chapters as separate files and include them in some master file. For 15,000 words it’s hardly worth it, but it’ll be useful for next year. I’d also like to change the default font to Gentium, for no other reason than to make a move away from default LaTeX formatting…

## I’m having one of those things… A headache with pictures…

So I looked into it and Topology and sigma-algebra are distinct things. Apparently a sigma-algebra need only be closed under countable intersection, whereas a topology requires arbitrary intersections to be included. Also topologies won’t necessarily be closed under complement, whereas sigma-algebras will be. But the smallest sigma-algebra containing some topolgy is called the “Borel sigma-algebra.” So that’s that all cleared up…

I took out a book on Euclidean geometry today written by none other than Charles L. Dodgson; better known as Lewis Carroll. Cool huh? And what is more, it’s written as a dialogue! I also recently managed to find Alfred Renyi’s Dialogues on Mathematics. So I’m pleased with both of them.

What with various talks and my being quite lazy I haven’t really managed to get a whole lot done today. And I’m to a conference tomorrow. So this week has been a bit of a write-off really. The real proper work on my dissertation kicks off on Monday. Hoorah!
