Angels are the winged and radiant messengers of God, who fly between heaven and earth, mediating between God and man. In the Purgatorio, Dante describes them as the bright birds of God, indicating their heavenly role and nature. In art, too, angels appear with the wings of a bird, but with the figure of a perfect man.

Superstring theory is one of the most exciting and actively pursued branches of physics today. The far-reaching claims made for this theory would, if correct, provide the much sought-after Theory of Everything, the unification of physics. It would enable the fundamental building blocks of matter to be identified and amalgamated in a common description, with a unified theory of all the forces of nature. This book explains the theory for laymen, in an introduction to the subject which originated in the BBC Radio programme, Desperately Seeking Superstrings. A clear, concise, non-mathematical explanation of the theory and its profound implications is followed by transcripts of interviews with all the most important physicists involved in its development. Superstrings makes a fascinating topic at the forefront of modern scientific research accessible to physicists, philosophers and general readers alike.

Jeder, der von der Quantenmechanik nicht schockiert ist, hat sie nicht verstanden. Niels Bohrs Diktum zeugt von der verblüffenden Wirkung der Quantenmechanik, die der klassischen Physik widerspricht und die Sichtweise der Wissenschaftler auf unsere Beziehung zur materiellen Welt dramatisch verändert. In diesem Buch interviewt Paul Davies acht Physiker, die an der Debatte und Prüfung der Theorie beteiligt sind und radikal unterschiedliche Ansichten über ihre Bedeutung haben.
