From 『George Gamow's Physics Train Ride』 to 『The Joy of Discovery』,
From 『Feynman's QED Lectures for the General Public』 to 『The Elegant Universe』,
Seung-San, who planned a physics book with the intention of creating a physics boom in the publishing industry,
Finally, we are taking the first step toward publishing the complete translation of "Feynman's Lectures on Physics"!

On October 4, 1957, the Soviet Union launched the artificial satellite Sputnik 1, beating the United States.
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 large-scale reforms.
In response, President Eisenhower issued a statement to the nation, established NASA, and devoted all his efforts to reforming the education system in mathematics and science.
As educational reforms were actively underway, Caltech attempted a new curriculum and a new way of teaching physics.
This lecture was recorded and transcribed from the beginning at the university level, and the book that compiled and published it is 『Feynman Lectures on Physics』.


The fact that the United States, after the so-called Sputnik shock, implemented educational reforms focused on strengthening science education and has maintained its status as an advanced nation ever since, has significant implications for us living in the knowledge-based society of the 21st century.
It is frustrating to see the current reality where we dream of a revival of science and engineering without systematically fostering basic science, and where we wait for talented individuals to choose basic studies based on short-sighted government support policies.

Professor Feynman had his own reasons for starting a basic physics course for first- and second-year students at Caltech.
Feynman, who was known for being smart before entering college, was saddened to see that students who were actually taking boring and rigid physics classes in college ended up becoming “stupid”. So he rolled up his sleeves to “save the students” and started his now legendary physics lectures.
In other words, the problem was, “How can we attract students’ attention to physics?” and the solution Feynman chose was, “I will show them how fun physics can be!”


The phenomenon of talented individuals flocking to law and medical schools due to students' avoidance of science and engineering has already become a national issue, and the phenomenon of even science and engineering students avoiding physics is a glimpse into the precarious future that our current educational reality will bring.
Because biotechnology, nanoscience, quantum computers, etc., which will be the main keywords of the 21st century, are based on quantum mechanics in physics.


Accordingly, various solutions are being proposed, but from a long-term perspective, I believe the fundamental solution is to change the perception of science through good books and good content.
As KAIST President Laughlin said, “Science and technology budgets should be invested where they are truly valuable, that is, in fostering the creativity and entrepreneurship of young people.” Rather than forcibly attracting applicants from science and engineering fields with limited financial support for specific fields, we should provide a fertile ground where they can experience the joy of discovery on their own, with the conviction that “if science is this fun and valuable, it is worth dedicating their lives to.”


Feynman's lectures are a book that allows one to fully experience the "hidden charm of physics" because they began with the recognition that physics is essential as a tool for understanding natural phenomena.
To readers who have had to enjoy Feynman's lectures only in the original English version, to readers who want to truly experience the essence of Feynman's lectures, and to the many young talents who love physics but are hesitating to pursue 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 still inspires countless students as well as professors who have already achieved academic success in their fields.
