Leonhard Euler was one of the most prolific mathematicians
that have ever lived. This book examines the huge scope of
mathematical areas explored and developed by Euler, which includes
number theory, combinatorics, geometry, complex variables and many
more. The information known to Euler over 300 years ago is
discussed, and many of his advances are reconstructed. Readers will
be left in no doubt about the brilliance and pervasive influence of
Euler's work.
