No matter how many friends you have on Facebook and MySpace, you won't have more real-life friends than the average person. Using mathematics to model online social networks is an evolving field, with techniques that have been used to model human interaction, such as network modelling, moving into the online world. Users of online social networks tend to build up long lists of "friends" with whom they only occasionally interact, if at all. Given that we can maintain more weak relationships online than we can in real-life, it is an interesting question to ask whether or not online social networks create as many close friendships as in real life. According to Will Reader of Sheffield Hallam University, the answer is no, and in this there is an interesting scientific and social point to be found.

If we are to believe the latest signs from outer space, the local aliens are keen mathematicians. A new crop circle appeared on the 1st of June this year in a barley field near Barbury Castle in Wiltshire, England, measuring 150 feet in diameter and correctly representing the first 10 digits of the irrational constant pi.

Issue 47 of Plus is our biggest issue ever and a mathematical showcase! Not only are we bringing you the best young writing talent with the winners of the Plus new writers award, but we are overloaded with features about the ways maths influences and shapes our lives. We investigate the overlap between the arts and maths, find out why mathematicians are always portrayed as mad in the movies, and learn about the nature of infinity and of prime numbers. We also challenge 118118 with some mathematics, uncover the mathematics of surprise and respond to recent newspaper reports that maths is no longer relevant. There are also all our usual puzzle and teacher package.

And if you want to give you eyes a break, tune your ears into our podcast, with 3 new episodes out today.

More information:

  • Competition winners
  • The 2008 Plus new writers award has been run and won. This year's competition saw an exceptional standard of writing.

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.

A damning new report into maths education blames an over-politicised system for narrow teaching, uninterested students and demotivated teachers.
