Many regard Albert Einstein as the greatest physicist since Newton. What exactly did he do that is so important in physics? We provide an introduction to his physics at a level accessible to an undergraduate physics student. All equations are worked out in detail from the beginning.Einstein's doctoral thesis and his Brownian motion paper were decisive contributions to our understanding of matter as composed of molecules and atoms. Einstein was one of the founding fathers of quantum theory: his photon proposal through the investigation of blackbody radiation, his quantum theory of photoelectric effect and specific heat, his calculation of radiation fluctuation giving the first statement of waveparticle duality, his introduction of probability in the description of quantumradiative transitions, and finally the quantum statistics and BoseEinstein condensation. Einstein's special theory of relativity gave us the famous E=mc² relation and the new kinematics leading to the idea of the 4dimensional spacetime as the arena in which physical events take place. Einstein'sgeometric theory of gravity, general relativity, extends Newton's theory to timedependent and strong gravitational fields. It laid the ground work for the study of black holes and cosmology.This is a physics book with material presented in the historical context. We do not stop at Einstein's discovery, but carry the discussion onto some of the later advances: Bell's theorem, quantum field theory, gauge theories and KaluzaKlein unification in a spacetime with an extra spatial dimension.Accessibility of the material to a modernday reader is the goal of our presentation. Although the book is written with primarily a physics readership in mind (it can also function as a textbook), enough pedagogical support material is provided that anyone with a solid background in introductory physics can, with some effort, understand a good part of this presentation.

With its clear figures and mathematical appendices (which serve to fill in some gaps in the discussion or material that may be unfamiliar), this is a book that can be very highly recommended to any physicist who enjoys a fascination with nature and an interest in history.
About The Author
TaPei Cheng is a particle physics theorist. He received a PhD from Rockefeller University with the noted physicist and Einstein biographer Abraham Pais. He is now Professor Emeritus at the University of Missouri  St. Louis, and an Adjunct Professor at Portland State University in Oregon. He is an elected Fellow of the American Physical Society. Among many concurrent appointments, he was at the Institute for Advanced study (Princeton), the University of Minnesota,and the Lawrence Berkeley Lab. Professor Cheng is the coauthor (with LingFong Li) of the book Gauge Theory of Elementary Particle Physics (Oxford, 1984) that has introduced the subject to several generations of particle physics students. Its companion book GTEPP: Problems and Solutions was publishedin 2000. He is also the author of Relativity, Gravitation, and Cosmology: A basic introduction, (Oxford 2005, 2nd ed. 2010). It is among the first books adopting a `physicsfirst approach' to the pedagogy of general relativity.
