Straight Statistics is a campaign set up by journalists and statisticians to improve the use of statistics by government, the media, companies and everyone else who uses stats. On the Straight Statistics website you can find all sorts of interesting articles responding to stats as they come up in the news — whether it's lucky house numbers, the impact of bird flu, or your chance to reach your 100th birthday.

Sixteen-year-old Rebecca Simpson, of Dame Alice Owens School in Potters Bar, has won a national competition to produce a creative photo connected to maths.

Winning entry by Rebecca Simpson.

The competition was run by Maths Inspiration, a great initiative that runs lecture events in theatres around the country, featuring speakers such as the writer and TV broadcaster Simon Singh. The competition, sponsored by Hewlett Packard, was open to all the 6,000 who attended the shows last autumn. Rebecca's entry, entitled Box and whiskers, depicts a cat being measured for its level of cuteness. It's a play on box and whiskers diagrams, which will be familiar to any GCSE maths pupil.

Rob Eastaway, the director of Maths Inspiration (and Plus author), said: "Our shows aim to prove there's more to maths than just taking exams, and humour is an important part of how we present maths. Rebecca's entry really caught the spirit of what we are trying to achieve".

Rebecca wins £200 and a signed copy of the book Fermat's Last Theorem by Simon Singh, while her school receives two top-of-the range Hewlett Packard graphing calculators.

Rob Eastaway has written several articles for Plus:

We've also reviewed some of his prolific book output:

This is it! The holidays have started, the turkey is defrosting and the presents are all wrapped ... all you have to do now is relax and be kind to one another. And since Christmas is all about love, the very last door of our advent calendar is devoted to it, too. The Plus team wish you a very merry Christmas and a happy new year!

Kissing the frog: a mathematician's guide to mating
What's your strategy for love? Hold out for The One, or try and avoid the bad ones? How long should you wait before cutting your losses and settling down with whoever comes along next? We investigate and save the national grid in the process.

Baby robots feel the love
It's not just us humans who can love and be loved!

23 is a prime number. Mathematicians love primes. But why? Find out with this prime collection of prime articles.

Mathematical mysteries: the Goldbach conjecture
There are lots of seemingly easy questions about primes that are nevertheless hard to answer. Here's the Goldbach conjecture.

Elusive twins
Primes tend to come in pairs: 5 and 7, 11 and 13, and so on. But do they really? That's the question posed by the twin prime conjecture.

Primes lie at the heart of one of the hardest open problems in maths. Find out more with The prime number lottery, The music of the primes and A whirlpool of numbers.

Safety in numbers
Primes are also what keeps your credit card details safe when you buy something over the internet. Find out how with Simon Singh.

The prime numbers are the atoms amongst the integers, and while we know that there are infinitely many of them, there's no general formula that generates them all. Here are two ways of sieving out all primes up to a given number: Sundaram's sieve and a geometrical method.

Oh, Christmas is so magical! But of course magic often boils down to being surprised. Find out how mathemagicians trade off the fact that you can usually predict precisely the outcome of doing something in mathematics, but only if you know the secret beforehand. Here's for some maths and magic!

Mathematicians are often good musicians. To prove this, here are some impressive compositions. Enjoy!
