What Eric Temple Bell calls "The Last Problem" is the problem of proving 'Fermat's Last Theorem', which Fermat wrote in the margin of a book almost 350 years ago. The original text of The Last Problem traced the problem from 2000 BC to 17th century France. Along the way we learn quite a bit about history, and just as much about mathematics. This book fits no categories. It is not a book of mathematics: it is a biography of a famous problem. Pages go by without an equation appearing. It is both a history of number theory and its place in our civilization, and a history of our civilization's relationship with mathematics. This rich and varied, wide-ranging book, written with force and vigor by someone with a distinctive style and point of view will provide hours of enjoyable reading for anyone interested in mathematics.-Print ed.

Holmes’ life is in danger. The criminal mastermind Moriarty is after him. Holmes has stood in his way several times, attempting to catch him and prove his guilty. The great detective creates a complex plan with the only goal to solve what is to be the greatest and crowning achievement of his lifetime. Moriarty is however an equal opponent who is not to be underestimated. Moriarty’s and Holmes’ paths cross near The Reichenbach Falls in Switzerland. Who will prevail in this battle between good and bad, law and outlaw? Will Holmes complete his life goal or he will die trying? "The Final Problem" is a part of "The Memoirs of Sherlock Holmes". Sir Arthur Conan Doyle (1859-1930) was born in Scotland and studied medicine at the University of Edinburgh. After his studies, he worked as a ship’s surgeon on various boats. During the Second Boer War, he was an army doctor in South Africa. When he came back to the United Kingdom, he opened his own practice and started writing crime books. He is best known for his thrilling stories about the adventures of Sherlock Holmes. He published four novels and more than 50 short-stories starring the detective and Dr Watson, and they play an important role in the history of crime fiction. Other than the Sherlock Holmes series, Doyle wrote around thirty more books, in genres such as science-fiction, fantasy, historical novels, but also poetry, plays, and non-fiction.

No mystery is too challenging for the infamous detective Sherlock Holmes and his partner, Dr. Watson. Holmes is at his best when the job seems impossible—or just plain absurd. From cases involving a strange group for red-headed men to a missing thumb, Holmes uses his powers of observation and deduction to solve even the weirdest mysteries. Scottish author Sir Arthur Conan Doyle published his first twelve original Sherlock Holmes short stories as serials in the UK's Strand Magazine from 1891-1892. This unabridged collection of the stories is taken from the book form, originally published in 1892.

This book continues from where the authors' previous book, Structural Proof Theory, ended. It presents an extension of the methods of analysis of proofs in pure logic to elementary axiomatic systems and to what is known as philosophical logic. A self-contained brief introduction to the proof theory of pure logic is included that serves both the mathematically and philosophically oriented reader. The method is built up gradually, with examples drawn from theories of order, lattice theory and elementary geometry. The aim is, in each of the examples, to help the reader grasp the combinatorial behaviour of an axiom system, which typically leads to decidability results. The last part presents, as an application and extension of all that precedes it, a proof-theoretical approach to the Kripke semantics of modal and related logics, with a great number of new results, providing essential reading for mathematical and philosophical logicians.

The author, a computer science professor diagnosed with terminal cancer, explores his life, the lessons that he has learned, how he has worked to achieve his childhood dreams, and the effect of his diagnosis on him and his family.
