Howard Mason Georgi III is Harvard College Professor and Mallinckrodt Professor of Physics at Harvard University, where he is also Director of Undergraduate Studies in Physics and Master of Leverett House. In 1995 he was elected to the National Academy of Sciences and received the J.J.Sakurai Prize. In 2000 he shared the Dirac Medal with Jogesh Pati and Helen Quinn. He is best known for early work in Grand Unification and gauge coupling unification withing SU(5) (Georgi-Glashow model) and SO(10) groups. He later proposed the supersymmetric Standard Model with Savas Dimopoulos in 1981. It is also worth mentioning his role in the Georgi-Quinn-Weinberg computation showing that the natural mass scale of unification is relatively close to the Plank scale and that the proton lifetime can naturally be extremely long. He has since worked on several different areas of physics including composite Higgs models, heavy quark effective theory, dimensional deconstruction and little Higgs theories. Most recently, with Arkani-Hamed and Cohen, he has found a class of 4-dimensional field theories in which extra dimensions can arise dynamically, providing a new slant of the meaning of space. The topological properties of such theories may shed light on critical issues such as the breaking of SU(2)xU(1) and supersymmetry. He continues to study these issues in the hopes they will shed light on the meaning of gauge symmetry.

In this book, the author convinces that Sir Arthur Stanley Eddington had things a little bit wrong, as least as far as physics is concerned. He explores the theory of groups and Lie algebras and their representations to use group representations as labor-saving tools.
The first complete introduction to waves and wave phenomena by a renowned theorist. Covers damping, forced oscillations and resonance; normal modes; symmetries; traveling waves; signals and Fourier analysis; polarization; diffraction.
A high-level, rigorous, and technical treatment of modern particle physics, this book was written by a well-known professor at Harvard University who conducts ongoing research programs in several areas of theoretical particle physics.Introductory chapters examine Noether's theorem, the electron, and SU (3) quark models. Subsequent chapters explore weak decays of light hadrons, effective low-momentum field theories, the transformation law for baryons, mode counting, effective field theories, and the renormalization group. Two helpful indexes review dimensional regularization and background field gauge. In addition to its value as a text for advanced undergraduate and graduate students of physics, this volume also serves as a reference for professionals.
