Why are some people generous and others selfish? There's no doubt that both strategies pay off under certain circumstances, but research (as well as everyday experience) shows that we are not mere opportunists — some people simply are nicer than others. This raises a question which intrigues evolutionary psychologists: is there a selective force that works in favour of a wide range of
personalities, preventing us from all evolving the same optimal character trait? A possible answer has recently been published by mathematicians from the universities of Bristol and Exeter.
There are three new singing stars on the block, but you're unlikely to hear them on Radio 1. The musical talents of HD49933, HD181420 and HD181906, three nearby stars which are hotter and larger than our Sun, were discovered by a group of scientists, led by Eric Michel, using data from the CoRoT space-based telescope. Michel and his colleagues accurately measured accoustic vibrations in these
stars that not only make for eerie listening, but also could reveal important information about how all stars evolve.
Are you a university maths student and want to share your passion with younger generations? Then why not take part in the second Further Maths Network - Rolls-Royce poster competition? Undergaduate and PGCE maths students from the UK are invited to submit posters conveying the essence of a mathematical topic they have covered at university. The poster should be aimed at school and college
students who are studying AS or A level mathematics. Entries from teams of students are welcome. The closing date is the 31st of March 2009, and two winners will receive a prize of £100 each. The winning designs will be printed as A1 posters and sent to schools and colleges registered with the Further Mathematics Network, and others with which FMN centres are in touch, for display in the
mathematics department, potentially reaching over 2000 schools and colleges.
Last year's winner, Michael Manfredi, was presented with his prize by Charlie Stripp of the Further Maths Network at the Rolls-Royce Learning and Career Development Centre in Derby (Michael's the one in the picture receiving the cheque!). You can see Michael's winning poster on cryptography on the Further Maths Network Website.
If you want to take part, then email your entry to Janice Richards, including your name(s) and full contact details, with the poster attached as an editable file. For more information, contact Richard Browne.
And if you prefer writing to designing posters, don't forget the Plus new writers award 2009. Anyone can enter, and there are special categories for university and school students. Winners will achieve everlasting fame through publication in Plus, and receive iPods and books. Closing date is the 31st of March 2009.
Gaffes, murder plots, and hockey mums — the US election circus is in full swing. Personality politics is partly a consequence of the first-past-the-post system — but what are the alternatives? Can any system guarantee to represent the will of the people? Do opinion polls manage to capture its voice? The following selection of Plus articles provides mathematical answers, insights and
With US election week upon us, we thought you might appreciate a look at alternatives to the first-past-the-post system used to elect the US President and Congress, as well as the UK government, and many others around the world.
For an even 'fairer' alternative to proportional representation, have a look at the Hare-Clark system of quota-preferential voting use in Tasmania. A good summary is at http://www.abc.net.au/elections/tas/2006/guide/hareclark.htm
The History of Mathematics Special Interest Group of the Mathematical Association of America (HOMSIGMAA) has just launched a writing competition for undergraduates. The MAA invites students to write on any topic in mathematical history they choose, and winners will receive a year-long MAA student membership, as well as books from the MAA bookstore. Closing date is the 31st of March 2009. For
more information, visit the HOMSIGMAA website.
And if you're not a student, or want to write about something other than history, or simply want to be published in Plus, then don't forget our very own Plus New Writers Award 2009. Besides the fame and glory of appearing in Plus, you could win an iPod and selected books. Closing date 31st of March 2009!
