Some good news for viewing mathematics articles in Wikipedia: MathJax rendering is now being supported on an experimental basis. You need to have a Wikipedia login to turn it on (in the Appearance preferences) but when you do you should get nicely rendered mathematics formulas in a font size matching the article text, instead of blocky misaligned bitmap images. Actually, this has been available for a few months, but much more recently they fixed some major bugs that were causing things like less-than signs not to work, so now it's finally usable.

Here are three new Wikipedia articles that use mathematical formulas, and one that doesn't:

Moment curve, a polynomial curve in d-dimensional space useful in many lower bound constructions in discrete geometry. It's closely related to the twisted cubic and rational normal curve, but I think distinct enough from them to warrant a separate article.

Slope number, the minimum number of distinct edge slopes needed to draw a given graph.

Wythoff array, a two-dimensional permutation of the positive integers that contains every sequence defined by the Fibonacci recurrence as one of its rows.

James Dugundji (1919–1985), an expert on fixed point theory. (I was indirectly led to him by a recent post by Dick Lipton on fixed points of natural language translation systems)

Finally, and unrelatedly, congratulations to the new Simons Investigators including several well-known theoretical computer scientists: Sanjeev Arora, Shafi Goldwasser, Russell Impagliazzo, Jon Kleinberg, and Daniel Spielman. (Via Peter Woit.)

Are you aware of the userscript for MathJax on Wikipedia written by the MathJax folks themselves?

I'm not sure about that one, but I've been using the one in User:Nageh/mathJax for some time now. But having it as a checkbox in the preferences instead of having to install magic javascripts seems like a big improvement to me.
