Is the wavefunction a mathematical convenience predicting probabilities for different observations of a particle, or does it have physical reality? A new mathematical theorem suggests the wavefunction is a real physical object.

Very thorough examination of the arguments about chainging the British voting system. The answer is, of course, that it is better. In many cases, it is possible to mathematically disprove the claims made by the No2AV campaign.

Fascinating post about an attempt to track usage of the words math and maths by using the Google tool, and detailing the various ways the search was misled (e.g. by books about Welsh culture: math is is a Welsh noun meaning “sort” or “kind”).

Experimental work showing that bees can solve the Travelling Salesman Problem, of determining the shortest route through a number of destinations.

Mathematically-inspired sculptures by Bathsheba Grossman, often in shapes impossible to make by traditional techniques. Very beautiful.

Blog of Daina Taimina, which she started after her book Crocheting Adventures with Hyperbolic Planes won the 2008 Diagram Prize “for the book with the oddest title of the year”. The blog is largely about mathematics, art, and the links between them, and is a warm and friendly (though often mathematical) read.
