Maths and Stats by Email | Is one a prime? Celtic knots: "Throughout history there have been many ways of writing ‘7’, but only one idea of seven. There have been many ways of writing addition, but one plus one has always been two. However, some mathematical ideas have changed meaning over the years. And recently, two American mathematicians decided to chart the history of a particularly tricky mathematical question: is one a prime number?"

Maths and Stats by Email | Abel prize, Pool tricks: "Article: A million dollars for an imaginary game of pool  
   

The things mathematicians imagine are often perfect. A mathematical sphere is smoother than any ball we could ever make, because it is made of ideas, not atoms. But mathematicians don’t just imagine simple shapes. This year’s winner of the million-dollar Abel prize is famous for imagining a mathematical pool table!

Maths and Stats by Email | Prime numbers, Advent puzzle: "Article: Why do mathematicians care about prime numbers?  
   

Once again, the maths world is celebrating a triumph regarding prime numbers. Earlier this year we reported on a new result by mathematician Yitang Zhang. His proof showed that there were infinitely many pairs of primes within 70 million of each other. Several mathematicians took Yitang’s work and refined the range from 70 million down to 4680. Now James Maynard has written a proof bringing the range down to 600, and has also investigated triplets and larger collections of primes. But why are mathematicians so interested in prime numbers?

Maths and Stats by Email | Money: "Article The value of money  
   

It’s clear that a one dollar coin is worth two 50 cent coins. Yet here in Australia, 50 cent coins are bigger, heavier, and made of similar metals. So why is the dollar coin worth more?

The short answer is that government tells us. In Australia, there are many laws about our money. One important law in this country states that Australian money must be accepted as a method of payment. These laws make sure that a one dollar coin is worth one dollar. But this isn’t the only way that money can be valued."
