A compilation of previously unpublished lectures delivered at the International Centre for Theoretical Physics by the pioneers and creators of modern physics --Bethe, Dirac, Heisenberg, Wigner, Klein and Landau (the sixth delivered by E Lifshitz). By sharing with us their own lives of physics, these outstanding physicists convey the sense of total dedication, the pleasure and elegance of scientific creation at its peak. Readers would acquire a deeper sense of the scope and nature of physics, and the insights of its fascinating diverse disciplines as the developments of modern physics are being unfolded through history.Contents:Foreword: Twenty-One Years After (Abdus Salam)Energy on Earth and in the Stars (H A Bethe)Methods in Theoretical Physics (P A M Dirac)Theory, Criticism and a Philosophy (W Heisenberg)The Scientist and Society (E P Wigner)From My Life of Physics (O Klein)Landau-Great Scientist and Teacher (tribute by E M Lifshitz)Readership: Physicists.Key Features:A tool book for analyzing nonlinear and non-stationary dataA source book for HHT development and applicationsThe most complete reference for HHT method and applications
