This book is based on the author's experience and lecture notes accumulated over the past 30 years teaching physics to university students. It expands upon many problems in physics with in-depth and diverse content from the perspective of mathematical physics.

If physics is the realm of intuition, observing natural phenomena and forming hypotheses, mathematics is the realm of rigor, proving those hypotheses and establishing logic.
Mathematical physics is the intersection of these two disciplines, and this book hopes to serve as a reliable guide for readers who wish to study physics at that intersection.
