As has always been the case Steven Weinberg's latest physics textbook Modern Physics Foundations is yet one more jewel that he has bequeathed to humanity and for which he will be forever remembered.<br>The book is immaculately organized and skillfully, clearly, and succinctly provides tremendous insights into the processes by which many celebrated physicists identified and derived major breakthroughs in Modern Physics.<br>The major topics in the book include Atomic Structure Theory, Basic Thermodynamics,  Special Relativity, Quantum Mechanics, Nuclear Physics, and Quantum Field Theory.<br>I particularly appreciate his book as an ideal text to review and relearn Modern Physics Foundations from the top theoretical physicist of our time.<br>Professor Weinberg's will be sadly missed by the scientific community.
