Magic, origami, climate change and stupid equations: maths at the British Science Festival

The 2009 British Science Festival is celebrating creativity, innovation and evolution with a huge range of events over 5 days, from 5 - 10 September at the University of Surrey. And being all those things, Mathematics will be the star of the show, with a fantastic programme of events:

  • The Magic of Computer Science — A clever conjuring show which challenges the audience to work out how the tricks are done. Performed by Peter McOwan, professor of computer science at Queen Mary University of London. (Saturday 5 September)
  • Mathematics and Meltdown: How Financial Systems CollapsePlus author Tim Johnson and Mark Robson answer the questions: How do we model what goes on in the City when the structures are changing so rapidly? And what is the role of statistics in modelling the speculation and high levels of interdependency across markets today? (Saturday 5 September )
  • From Flapping Birds to Space Telescopes: The Modern Science of Origami — Robert Lang, an artist and expert on the mathematics of origami shows how its theorems illuminated long-standing mathematical questions and solved practical engineering problems which even have applications in space. (Sunday 6 September)
  • Why do journalists love stupid equations? — Simon Singh, journalist and documentary maker, asks why the press are suckers for pseudo-mathematical formulas which PR companies cynically use to create quick and easy news stories. (Presidential lecture Sunday 6 September)
  • Chaos in Climate: An Inconvenient Truth? — Being able to make sense of the chaos in weather and climate is one of our greatest triumphs. Ian Roulstone and Lucia Elghali, from the University of Surrey show how mathematical modelling is also helping us to devise strategies for adapting to a changing climate. Tuesday 8 September
  • Fly Me to the Moon — Going back to the moon is the latest focus for space travel. But new mission designs mean sophisticated new mathematical techniques will be needed. Explore with Mark Roberts and Phil Palmer from the University of Surrey. (Thursday 10 September)

For more information about the festival visit or call 0207 019 4947. And you can read more about magic, finance, climate change and space travel on Plus.

The media is buzzing with swine flu numbers. Latest government figures say that over 100,000 people in England came down with swine flu during the last week — that's almost twice the amount of the previous week, and up to five times higher than the seasonal flu figures recorded last winter. Twenty-six people in England have died of the disease.

But where do the numbers come from? Patients with swine flu symptoms are no longer tested in the lab or traced, so the published figures are estimates, rather than absolute numbers.

As part of our celebration of the International Year of Astronomy 2009 we brought you the article Are the constants of nature really constant?, in which John D. Barrow tells us how it all depends on which constants you choose. In the podcast of this interview you can hear how changes in the constants that define our Universe might have implications for extra dimensions, gravity, and climbing flies...

Listen to the podcast.

If this has whetted your appetite for astronomy, then why not take part in our online poll to nominate the next question we'll put to the experts.

What would you like to know about your Universe — The fourth online poll

This poll is now closed. The most popular question was: "How does gravity work?" You can read the answer on Plus, or listen to the podcast. Thank you for taking part and don't forget to vote in the current poll!

This is the fourth online poll in our series to celebrate the International Year of Astronomy 2009. Choose your favourite question from the list on the right, and we'll put the one that proves most popular to world-leading astronomers and cosmologists, including Astronomer Royal Martin Rees and author and cosmologist John D. Barrow. The poll will remain open for a month and the answer will be published in a Plus article and podcast soon after. If your most burning question is not on this list, then leave a comment on this blog and we'll endeavour to include it in a future poll — there will be three more polls dotted throughout the year.

The most popular questions in the first two polls were What happened before the Big Bang? and Are the constants of nature really constant?. Read the answers by clicking on the links, and discuss them on our blog. The third poll came up with the question "What are dark energy and dark matter?" and we will publish the answer on Plus shortly.

A topic that I would like covered are the different black holes and how they formed:
- mega black hole
- stella black hole
- micro black hole
- others ....

New simulations reveal that turbulence created by jets of material ejected from the Universe's largest black holes can stop stars from forming.

Gettin' funky with da fractals

Summer is the season for music festivals, and why not take in some science between acts by visiting the Guerilla Science tent at the Secret Garden Party this weekend. Plus was particularly tempted by dancing with fractals on Thursday 23rd with Impossible Objects, catching rays with Helen Mason on Friday 24th, hunting for Higgs with John Butterworth and searching for symmetry with Ben Allanach on Saturday 25th, and the Beatbox laboratory on Sunday 26th July.

Find out more about Guerilla Science at the Secret Garden Party on their website, and find out about Our dynamic sun from Helen Mason and Particle hunting at the LHC from Ben Allanach on Plus. And check out the Guerilla Science Freestyle featuring Ben!
