**Review: ** From the summary: ``During my long life I have written many papers on my favourite unsolved problems. In the collection below, all the problems are either new ones, or they are problems about which there have been recent developments.''

The problems cover number theory, combinatorics, graph theory, geometry, analysis, set theory and group theory.
