Fermat's Last Theorem: by Simon Singh.

Anyone who needs being reminded that there are mountain peaks of people out there through history past and present, and shall in all likelihood always be, far more brilliant and dedicated and hard working and perhaps lucky - some far from lucky but possession of all the other aforenamed virtues to larger extents - then that person can do no better than to pick up this little volume and read it start to finish. If then it makes one feel very small indeed, so one finds it hard to live with oneself and call oneself a human belonging to the same species as these giants, one better make sure one is in close proximity with someone who reminds oneself why one deserves to live.
