## Euler

**Surein Aziz**explores one of the most beautiful equations in mathematics

**Chris Sangwin**takes us through excerpts of Euler's algebra text book and finds that modern teaching could have something to learn from Euler's methods.

**Phil Wilson**continues our series on the life and work of Leonhard Euler, who would have turned 300 this year. This article looks at the calculus of variations and a mysterious law of nature that has caused some scientists to reach out for god.

**Abigail Kirk**explores one of the formulae that carry his name.

**Robin Wilson**starts off a four part series on Euler with a look at his life and work.

**Lewis Dartnell**explained how chaos on the brain is not only unavoidable but also beneficial. Now he tells us why the same is true for our solar system and sends us on a journey that has been travelled by comets and spacecraft.
