Richard Feynman is famous as an outstanding physicist who advanced early 20th century physics with quantum electrodynamics, but it was in the lecture hall of Caltech (California Institute of Technology) where he truly demonstrated his worth.
His lectures on basic physics, electromagnetism, and easy-level quantum mechanics to first- and second-year undergraduates at Caltech later became legendary in the physics world.
Feynman's greatest strength was, above all, his rare talent for "making difficult things easy to understand."
Moreover, because the lecture was aimed at general undergraduate students rather than physics experts, Feynman's explanations were known to be concise, logical, humorous, and to the point.


Richard Feynman's unique lecture style was so popular that he was described as "a delicate blend of theoretical physicist and circus clown, with dazzling gestures and sound effects" (The New York Times).
Armed with his quick, sharp speech and sense of humor, Feynman's passionate and fantastic lectures, which he delivered while moving freely across various fields of physics, are said to have left a deep and unforgettable impression on those who saw him even once.


This book is a supplement to the lecture notes, and is the fourth volume of the newly published Feynman lecture notes, which compiles four lectures and practice problems that were omitted from the book version of Feynman's legendary lectures, "Feynman Lectures on Physics," but have now finally come to light.
With the final publication of "Feynman's Guide to Physics" in Korea, readers can now enjoy Feynman's legendary physics lectures in their full and complete form.
Feynman's characteristically witty remarks and inspired explanations are fully demonstrated in this book.
As you read each sentence as if you were listening to Feynman's own voice, you will soon realize how fascinating physics is.
In particular, this book is interesting because it contains Feynman's advice for Caltech underachievers (to choose a specialty and strive to be the best in that field), and it explains the basic laws of physics and physics tips in an easier and clearer way, and it also details the process of solving problems through trial and error, so it will be an opportunity for young people and general readers to more easily encounter Feynman's lectures.
