Find out about the beautifully intuitive concept that lies at the heart of calculus.
Scientists have calculated the decimal digits of the number pi to a record 62.8 trillion places.
You may have heard about the Fibonacci sequence, but have you heard of N-bonacci sequences?
We take the real numbers for granted, but what are they really?
Compound interest is the curse of debt and the blessing of saving. Find out how it works and what it has to do with one of the most important numbers in mathematics.
What is 1-1+1-1+1-1+...? How infinite sums challenge our notion of arithmetic.
What do you get when you add up all the natural numbers 1+2+3+4+ ... ? Not -1/12! We explore a strange result that has been making the rounds recently.
The number pi can be expressed beautifully in terms of infinite sums. For practical purposes though, these sums are rather disappointing: they converge slowly, so you need to sum a large number of terms to get accurate estimates of pi. Here's a clever way to make them converge faster.
Usain Bolt, the "fastest man on the planet", aims to get his 100 metre world record of 9.58 seconds down to 9.40 seconds. What has mathematics got to say about this quest?
