About Feynman's Lectures on Physics

On October 4, 1957, the Soviet Union successfully launched Sputnik 1, the world's first artificial satellite.
This shocked the United States, which was far ahead in economy and science and technology.
The United States, which failed to secure an advantageous position in launching artificial satellites, a symbol of advanced science, realized the need to foster basic science and embarked on a large-scale educational reform.
In response, President Eisenhower issued a statement to the nation, established NASA, and devoted all his efforts to reforming the math and science education system.
As educational reforms are actively underway across the United States, the California Institute of Technology (Caltech) is experimenting with a new curriculum and a new way of teaching physics.
This lecture was recorded and recorded from the beginning at the university level, and the book that compiled and published it is 『Feynman Lectures on Physics』.


Professor Feynman had his own reasons for starting a basic physics course for first- and second-year students at Caltech.
Students who were known to be smart before entering college were becoming 'stupid' after taking boring and rigid physics classes.
Feynman, feeling sorry for this, rolled up his sleeves to “rescue the students” and began his now legendary physics lectures.
The key point of the lecture was “How to attract students’ attention to physics?” and the solution Feynman chose was “I will show you how fun physics can be!”


For the past 40 years, Feynman's Lectures on Physics have never been out of print, inspiring countless students, teachers, and physicists alike, providing a forum for ideas and discussion.
Even Feynman himself was inspired by this.
Feynman's great achievement goes beyond seeing everything from a new and fresh perspective.
Feynman was not just a great teacher, he was a great teacher of teachers.
Feynman himself said that his contribution to physics would be his lectures, not quantum electrodynamics or other theories that might drift away.


"Feynman's Lectures on Physics" is a book that allows you to fully experience the "hidden charm of physics" because it begins with the recognition that physics is essential as a tool for understanding natural phenomena.
For readers who have only been able to enjoy Feynman's lectures in the original English version, for those who wish to truly experience the essence of his lectures, and for the many young talents who love physics but are hesitant about pursuing a career in physics, I would like to share Feynman's confident voice, saying, "Science is a fun game."
I hope that the physics boom will be rekindled once again through "The Feynman Lectures on Physics," which continues to inspire not only students but also professors who have already achieved academic success in their fields.

The Structure of Feynman's Lectures on Physics

More than 40 years have passed since Feynman's legendary lectures were published as a book, and our understanding of the physical world has changed significantly, but "Feynman's Lectures on Physics" has withstood those changes.
It is no exaggeration to say that the true nature of physicist Feynman is revealed in these lecture notes.
This book finally shines with the power of solid reasoning that penetrates the principles of things and an ingenious problem-solving method that no one can imitate.
Thanks to Feynman's signature physical insights and teaching methods, it remains as powerful today as it was when it was first published.
Perhaps no other physics book has had such a long and widespread influence.


The Feynman Lectures on Physics series consists of four volumes.
Among them, Volumes I, II, and III are lectures Feynman gave at the California Institute of Technology from the fall of 1961 to May 1963, which were organized and transcribed by Robert Leighton and Matthew Sands.
This was published in 1963 under the title Feynman Lectures on Physics.
Volume I is a reconstruction of 'general physics' with Feynman's characteristic explanations, and covers mechanics, radiation, and heat.
Volume II, which deals with electromagnetism and physical properties, stands out for its depth of content not found in other electromagnetism books, and Feynman himself expresses considerable pride in his lecture notes throughout.
And the newly published Volume III deals with quantum mechanics, which can be said to be Feynman's specialty, and is evaluated as a gem of a book that shows the core of quantum mechanics with an original explanation that no one can imitate.


"Feynman's Guide to Physics" is an appendix to the lectures, consisting of three lectures on Feynman's problem solving, one lecture on inertial derivation, and problems and solutions prepared by Feynman's colleagues Robert Leighton and Locus Vogt.
This book was created by Michael Gottlieb and Ralph Leighton, who were fascinated by Feynman's lectures, and successfully restored four lectures, audio recordings, and photographs that were missing from the lecture notes. It is an excellent reference book that is more than enough to supplement the existing legendary lecture notes.
