With the development of the theory of relativity by Albert Einstein, physics underwent a revolution at the end of the 19th century. The boundaries of research were extended still further when in 1907-8 Minkowski applied geometrical ideas to this area of physics. This in turn opened the door to other researchers seeking to use non-Euclidean geometrical methods in relativity, and many notable mathematicians did so, Weyl in particular linking these ideas with broader philosophical issues in mathematics. The Symbolic Universe gives an overview of this exciting era, giving a full account for the first time of Minkowski's geometric reformulation of the theory of special relativity.
