Kepler's conjecture
In the first of our tenth birthday year issues, Plus is celebrating the very best that maths has to offer. If you've ever wanted to fly with the birds and swim with the fishes, get the inside knowledge on great London landmarks or just enjoy going to the movies, then this is the issue for you. And we also say happy birthday to the great mathematician Leonard Euler.
It's International Year of Astronomy and all eyes are on Galileo Galilei, whose astronomical observations 400 years ago revolutionised our understanding of the Universe. But few people know that Galileo wasn't the first to build a telescope and turn it on the stars. That honour falls to a little-known mathematician called Thomas Harriot, who excelled in many other ways too. Anna Faherty takes us on a tour of his work.
Has mathematics become an experimental science?
