The Fields Medal is the most prestigious prize in mathematics, akin to the Nobel Prize. It is awarded to up to four mathematicians at each ICM, which meets every four years. The prize is awarded to mathematicians under the age of 40 in recognition of their existing work and for the promise of their future achievements. You can read more about the Fields Medal on Plus.
And the Fields medal isn't the only prestigious prize being awarded at the ICM. The Rolf Nevanlinna Prize recognises achievements in mathematical aspects of computer and information science. The Carl Friedrich Gauss Prize, which was first awarded at the last congress in 2006, is for outstanding mathematical contributions that have found significant applications outside of mathematics. The first recipient of this prize was the Japanese mathematician Kiyoshi Itô, then aged 90, for his development of stochastic analysis. His work has allowed mathematicians to describe Brownian motion — a random motion similar to the one you see when you let a particle float in a liquid or gas. Itô's theory applies also to the size of a population of living organisms, to the frequency of a certain allele within the gene pool of a population, or even more complex biological quantities. It is also now integral to financial trading as it forms the basis of the Black-Scholes formula underlying almost all financial transactions that involve options or futures. (You can read more about the Black-Scholes formula in A risky business: how to price derivatives on Plus.)
This years ICM also sees the inauguration of a new prize, the Chern Medal, for an individual whose accomplishments warrant the highest level of recognition for outstanding achievements in the field of mathematics, regardless of their field or occupation. The medal is in memory of the outstanding Chinese mathematician Shiing-Shen Chern. Plus is looking forward to finding out the winners of all of the prizes at this year's ICM, and more importantly, to learning about their mathematical achievements and how they have contributed to mathematics and society at large.

Plus is proud to host the 68th edition of the carnival of mathematics, celebrating mathematical blogging!
The carnival invites mathematical bloggers to submit the recent blog posts they're most proud of and the current host then publishes a list of the best ones on the first Friday of the month. (You can find out more at Walking randomly.) So here we go....
Renowned cosmologist and mathematician John D. Barrow has turned his attention to rowing, with intriguing results. As others did before him, Barrow noticed that the force generated by a rower in a boat has two components: one drives the boat forward and one to the side. Since the sideways motion represents wasted effort, rowers should be positioned in the boat so that it is minimised. So what exactly is the ideal positioning of rowers, the ideal rig?
It's a mathematical problem and Barrow has come up with solutions to an idealised version, including a rig that never seems to have been used before in competitive rowing. Last week the New Scientist put Barrow's ideas to the test in a little paddle down the Thames ... you can read about the results on the New Scientist website.
If you'd like to read more of John D. Barrow's work, have a look at his Plus column Outer space.
After several months of hard work, particularly by computer legend Owen Smith, the new Plus site is now live!
All the Plus content you know and love is still there, and is still accessible at the same URLs. And with a few changes to the layout and navigation, we hope the new site will be easier to use. All the different types of content we produce is listed in the top bar. Every article now has a comments feature at the bottom of the page, which you can use by registering with Plus — it's free and easy to do. Registering with Plus will also enable you to create pdf documents from our content. You can register here.
We've done our best to make sure everything on the new site works, but if you do come across any problems or something you don't like, then please get in touch, either by emailing us at firstname.lastname@example.org, or by posting a comment on the relevant page. We'd be really grateful for your feedback and we hope you like the new site!

Watching cyclists struggle through the Tour de France from our armchairs (or should it be deckchairs?) is great fun, but as Burkard Polster and Marty Ross have discovered, it would be even more fun if the cyclists cycled in circles.
If you draw a closed convex loop on the ground and cycle so that your back wheel follows the loop, your front wheel will trace out a larger loop. It turns out that the area in between the two loops is always the same, regardless of the shapes and sizes of the two loops: if the length between the two wheel hubs of your bike is L, then the area between the loops is always π L2. Go to the The Age Education Resource Centre to find out why...
