We all have our problems! Mathematicians can be divided into theory-builders and problem-solvers. In these lectures, we look at some problems that have fascinated mathematicians for 2000 years, concluding with a discussion of the future. Squaring the circle and other impossibilities The three classical problems of Ancient Greece - squaring the circle, trisecting the angle and doubling the cube - remained unsolved until the 19th century. What were they, what methods were tried for tackling them, and how were they eventually solved?
