Albert Einstein (1879-1955) in 1921.

Albert Einstein's general theory of relativity has been described as an "act of pure creation". It also celebrates its 100th birthday this year. Find out about the theory and Einstein's struggle to formulate it in this Plus article. You can also read a shorter and easier article on Wild Maths.

Wild Maths encourages students to explore maths beyond the classroom and is designed to nurture mathematical creativity. The site is aimed at 7 to 16 year-olds, but open to all. It provides games, investigations, stories and spaces to explore, where discoveries are to be made. Some have starting points, some a big question and others offer you a free space to investigate.
