This is a story about a particularly awful bit of science reporting. It’s taken me a while to sort out what’s going on. First I thought it was bad maths, then I thought it was bad science, and now I think it might be bad journalism. But it might be none, all, some, or a superset…
The invariant subspace problem is solved for Hilbert spaces?
Update 05/02/2013: Cowen and Gallardo say that a problem has been found in their proof and they no longer claim an answer to the invariant subspace problem. At the congress of la Real Sociedad Matemática Española yesterday, Eva Gallarda and Carl Cowen presented an affirmative answer to the invariant subspace problem on separable Hilbert spaces. While…

Student placement with the Numerical Algorithms Group
Mathematical and statistical software specialists The Numerical Algorithms Group (NAG) are advertising a twelve month student placement in Oxford as a software engineer. We are looking for somebody who has completed the equivalent of two years of a three-year degree course. A strong computing component in the course is important and some mathematical background or…
Chrome now supports MathML
Update 07/02/2013: Google giveth, and it taketh away. MathML support in Chrome has been disabled until it’s “production-ready”. Putting maths on the web has always been a tricky proposition. Typesetting notation is a highly complicated procedure, so for years people have got by either by compromising on aesthetics and writing equations in plain, unadorned text, or…
This is an ex-parrot. ‘Is plumage has dimension 1
A paper by Lorenzo Pérez-Rodríguez, Roger Jovani and François Mougeot in Proceedings B, “Fractal geometry of a complex plumage trait reveals bird’s quality“, claims that the measurement of the fractal dimension of a red-legged partridge’s chest plumage is a good indicator of its health. I know what you’re thinking: another ‘non-mathematicians pick trendy term to describe…
