Into the book
Enter a world of wonder through toys!
I teach physics at a university.
There's a lot of content in a thick physics textbook.
It also contains a lot of formulas that people are afraid of.
College physics classes can be incredibly hectic, with so much to teach and learn.
A student, tired of calculating formulas on the whiteboard, briefly looks away and looks out the window.
The white fluffy clouds floating in the blue sky look really beautiful.
Physics explains natural phenomena with theories in the form of mathematics, such as why the sky is blue and why clouds floating in the sky do not fall.
But students who are trying to understand the material they encounter in class are often distracted by the equations they just saw.
And you don't realize that the very formula is talking about tiny water droplets in the clouds outside the classroom window.
When describing the fall of an object through air using formulas, can you sense the physics of it by looking at the blue sky, white clouds, and the water droplets falling within them? I've long hoped that by explaining physics theories using formulas, students would be able to see and understand the phenomenon firsthand.
So I started collecting simple toys that applied physics principles.
Excluding those that are too expensive or too big to bring into the classroom.
Although not originally intended as physics toys, I've also collected a number of small objects that can demonstrate the principles of physics.
When I started class by placing the toys I brought on the desk, just in time for the class that day, the students would focus on the class with curious eyes, waiting for me to show them the toys.
So one, two, three, little by little, the number of physical toys I had increased.
In the summer of 2020, I had a small exhibition of my physics toy collection.
The people who came then touched the toys themselves and listened to my story with interest.
Of course, I was happier showing off my toys and talking about the physics behind them.
This book originated from that very exhibition.
Once again, I would like to express my deepest gratitude to Kim Mi-seon of Lee Kim Publishing for her wonderful planning and execution of this exhibition.
Afterwards, I started serializing “Kim Beom-jun’s Physics Toys” on Naver Premium Content Channel, and those articles were collected, revised, and supplemented, and now they are being compiled into a book.
I would also like to thank Naver for their understanding in publishing the serialized content as a book.
I'm also preparing an experimental video on my YouTube channel, 'Beomjun's Molecular Biology', so please keep an eye out for it.
I hope you enjoy reading this book as much as I enjoyed writing it.
There are many interesting and fascinating physical phenomena in our daily lives, right next to you.
There are quite a few things that can be understood and explained through physics, even if we are so familiar with them that we have never thought deeply about them.
I still get a chill down my spine when I realize that physics can explain phenomena that I've always taken for granted because they're so familiar.
The world is wonderful and physics is wonderful.
It is truly amazing that we humans have created such wonderful physics.

Publisher's Review
“Wow! The world is full of physics!”
★ Professor Kim Beom-jun, the physics fairy, reveals his treasured collection of toys.
★ Recommended by Professor Sangwook Kim, a physicist with a wealth of knowledge
★ Learn the principles of physics easily with cute and novel toys.
When we say physics, some people may get confused, but physics is 'the principle by which our world operates.'
So the laws of physics are everywhere in the world.
But because the laws cannot be seen with the eyes, physicists expressed physics with formulas, graphs, and pictures.
Is there another way to see and experience physics firsthand? After much thought, physicist Professor Kim Beom-jun has finally found just such a thing.
It's a toy.
Actually, I didn't plan on collecting physical toys from the beginning.
I just bought one or two fun and interesting toys whenever I saw them, and before I knew it, toys were piling up all over the lab.
Using toys in university classes has helped to increase students' interest and concentration.
A small exhibition was also held with the toys collected in this way.
I decided to explain the physical principles contained in toys in a simpler way, and the result of my writing is “Kim Beom-jun’s Physics Toys.”
This book covers a wide range of physics disciplines, from classical mechanics to thermodynamics and electromagnetism, and explains the fundamental concepts of physics in a tangible way.
As you read the book while looking at the amazing toys and playing, you will naturally learn the principles of physics.
Professor Kim Sang-wook of the Department of Physics at Kyung Hee University said, "Professor Kim Beom-jun explains the principles of physics toys in an easy but thorough way," adding, "It's okay even if you don't understand all the principles.
"Just immerse yourself in the mysterious allure of physical toys," he recommended.
This book does not simply provide knowledge of physics.
The primary purpose of this book is to convey the wonder and beauty of physics.
The laws of physics are the fundamental principles that govern everything in this world, and they are the wisdom that humanity has acquired over the ages.
Discovering the wonders of cute toys can also give you a new perspective on the world.
Professor Kim Beom-jun honestly shares his experience collecting and observing toys as a physics student and as a human being.
This book fully captures the passion that led to a small movement born from curiosity, culminating in a book.
And it also teaches you how to make your own physics toys.
Through this book, readers will be able to experience the joy of science and the excitement of exploring the world.
Even those who think physics is difficult and unfamiliar can easily fall under its spell.
By the time you finish reading the book, you might be building your own collection of physics toys.
