The 2008 Plus new writers award has been run and won. This year's competition saw an exceptional standard of writing. The winning entries include biographies of two of the greatest mathematicians of the last 100 years, as well as articles on the mathematics of Google, ants that do maths, why we should (or should not) woo brunettes, the dangers of probing the infinite, and joining the
mathematical mile-high club...
The Fourier transform is a piece of maths that is, almost single-handedly, responsible for the digital revolution. Digital music and images would be impossible without it, and it has applications in anything from medical imaging to landmine detection. We asked Chris Budd what the Fourier transform does, and how it does it. This podcast accompanies the Plus article Saving lives: The mathematics of tomography.
Maths has long been a theme in the movies. Plus talks to Madeleine Shepherd, organiser of the maths film festival at the recent Edinburgh science festival, about how maths has been presented in the movies over the years, with particular reference to three more recent films, Cube, Pi and Flatland. For more on maths in the movies read the Plus article Maths, madness and movies.
"I was very surprised and moved to see that it flew the same way it does on Earth," Doi was quoted as saying in the Mainichi Shimbun.
