Plus Blog

July 22, 2010

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 plus@maths.cam.ac.uk, 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...

Cows kill 20 Americans every year. But you can halve your chance of dying of a heart attack by drinking 8 bottles of wine a week. Laugh in the face of death at the new comedy show “Your Days Are Numbered – the maths of death”, either at the Edinburgh Fringe (Assembly@George Street, 5-30th August) or at the last London previews on July 27th (2.30 and 7.30 pm) at the Cockpit Theatre .

Stand up mathematician Matt Parker (winner of the audience award, FameLab 2009, and warm up act for last year’s RI Christmas lectures) and comedian Timandra Harkness (“a deadly wit” – the Scotsman) will cut through newspaper headlines like “Junk Food kills 40,000” and give you the real lowdown on your odds of dying and how you can lengthen them. With funding from the Wellcome Trust, they're not allowed to just make stuff up.

You have a 0.000043% chance of dying during this show, but at least you will die laughing.
