Should international travel be banned in the face of swine flu? Should life-saving drugs be withheld because they're too expensive? Should the government ban alcohol? And are bacon sandwiches really that dangerous?
Plus may seem like an unlikely place to look for answers to these questions, but this is about to change. With support from the Wellcome Trust we're launching a new project, called Do you know what's good for you?, which will look at the role of mathematics and statistics in the biomedical sciences.
Just over two weeks after the outbreak of swine flu, sorry, H1N1, most of us have come round to the idea that a pandemic doesn't always necessitate panic. The infection is spreading steadily, but in most people it's relatively mild and only a very small number of people have died outside Mexico. So were initial media reports just hype?
A very good article which shows just how important fairly simple maths is in thinking rigorously about the world around us.
For example, I had heard of the idea of herd immunity before and had never really understood it - from a biological perspective I just thought tha if there were unvaccinated individuals around they would catch the disease so you'd have to immunise everybody. But once you introduce the idea of an reproduction rate, it's absolutely clear why that's not the case - because any geometric series with
r<0 tends to 0.
Of course as the article goes on to make clear, it's more complicated than that as a geometric series is probably not the appropriate model, but that's what makes it so fascinating. Thanks Plus!
If you're thirsty for knowledge, then go along to this free Gresham College lecture taking place in London on Wednesday the 13th of May. It marks the publication of John D Barrow's latest book, 100 Essential Things You Didn't Know You Didn't Know, which answers one hundred essential questions of existence. From winning the lottery, placing bets at the races and escaping from bears, to
sports, Shakespeare, Google, game theory, drunks, divorce settlements and dodgy accounting; from chaos to infinity and everything in between. Barrow writes a regular column for Plus, so you might be lucky enough to see some maths you've seen in Plus live on stage.
The lecture starts at 6pm and you can find directions on the Gresham College website.
Thank you very much to all the Plus readers who have given us such generous donations over the past few months.
Thanks to your generosity, as well as new grants from the Isaac Newton Trust and the Wellcome Trust, the future of Plus is now secure until July 2010.
Your donations arrived in response to a fundraising campaign we launched in December last year. At the time, the future of Plus was looking increasingly insecure, as our core funding was due to run out and the financial climate did not give much cause for optimism. As part of the Millennium Mathematics Project at the
University of Cambridge, Plus is non-profit-making, receiving no statutory funding, and is entirely dependent on donations and grants from individuals and organisations committed to the public understanding of mathematics. But thanks to your swift response and generosity, together with the support of our other sponsors, we're able to continue to bring you the
usual range of content from the fascinating world of maths, and — very importantly — Plus will remain free of charge for all its readers.

From string theory to maths education via investment banking
If you're worried that a mathematics degree might limit your career options, then there couldn't be a better person to talk to than Steve Hewson. Find out how his varied career has taken him from the lofty heights of theoretical physics, via the trading floor of a major investment bank, into the maths classroom, and has also seen him writing his very own maths book.
Hello, i was just wondering if you need a math credit to become an early childhood educator, and i also would like to know what other things could i become with a math credit because i need to decide now, its my last year of high school. Please help!!! THANKS!
