The world according to Wikipedia

This is not-a-graph that is the direct result of this xkcd comic*, which has the following gem in the mouseover:
Wikipedia trivia - if you take any article, click on the first link in the article text not in parenthesis or italics and then repeat, you will eventually end up at "Philosophy."
It is true probably because the first paragraph of every article attempts to put the topic in a wider context, which means the first link will probably lead to a topic broader than the previous one, and all roads lead back to how we organise information and knowledge, and how we think -- philosophy!!

But what is just as interesting is how all those paths converge. So I did some clicking around, and came up with this diagram. It traces fields of study (=majors, ="concentrations" because Brown needs to be special) offered at the undergraduate level at Brown University (see a list here) through the Wikipedia maze and shows how they all converge onto philosophy. This is an incomplete selection of concentrations because not all would fit, and I excluded 'sub-field' concentrations e.g. biochem, biophysics, geo-bio...with the exception of marine biology, which is my concentration and therefore I am obviously biased toward wanting it in there.

Interestingly enough, there are only 3 links into philosophy for 40+ fields of study mapped, and the third link only includes one field, education. Everything else eventually goes back to math or to academia, academic communities and interactions. Some paths are also surprisingly weird...check out engineering and business studies. Business studies is linked through 'planet' but astronomy isn't.


*it is also the result of Jenni posting this on Facebook so that I was thoroughly distracted for the rest of the night and did no studying for my GRE. so this entire post is her fault.

Modelling change

So I've been been thinking about math and mathematical models quite a bit lately, partly because they've been showing up in many places this semester.

When I was 8, this was my idea of a model...except that back then I don't think the textbooks were in colour. We drew little bar models all the time. Everyone's models were always straighter and neater than mine, and some kids would bring their colour pencils and colour them in for no good reason at all. Drawing models was the way to solve every math problem and it was awesome until your older neighbour/friend/cousin taught you algebra. Then they became the most ridiculous, tedious things in existence because your teacher wouldn't let you stop using them.

Apparently now they're all the rage among homeschooling parents in the US (and possibly in Utah too?). I guess my messy little primary school self didn't appreciate them enough because I hated having to draw so many straight lines.


Now (10+ years later) models look like this, and there are lots of them everywhere :)
I realised I have actually not had a math class in something like 3.5 years, even though I've used it extensively in some of my classes. I might take an applied math class or two before I graduate...

A hypothesis

We talked about density dependence in a tree, masting in another tree and the link between environmental and population synchrony in soil mites. Today was a slow day...
