Into the book
Almost everything we see around us is moving and eventually comes to a stop.
If you tap an eraser on a desk, it will slide across the desk, roll two or three times, and then stop.
When you throw a baseball, it flies for a while, then falls to the ground, bounces or rolls a few times, and eventually stops.
Even if a major league pitcher throws a fastball over 100 miles per hour, the ball will only travel farther and eventually fall to the ground.
The result of stopping does not change.
How can I keep moving without stopping?
--- From "The Nature of Movement"
If we ignore both friction and air resistance between the roller coaster and the rail, we can think of the roller coaster as an isolated system, and as the roller coaster goes up and down, the kinetic energy and potential energy can go back and forth.
However, according to the law of conservation of energy, the mechanical energy, which is the sum of the two energies, or total energy, will not change and will remain constant.
--- From "The Physics of Roller Coasters"
Cooking began when humans began using fire.
Making a fire is a chemical reaction, which is a rapid oxidation reaction in which a substance combines with oxygen, producing a large amount of heat and light.
Before that, you probably ate the meat of animals that died in forest fires and found that it was softer and tastier than raw meat.
--- From "Cooking with Fire"
How does my smartphone know exactly where I am? It has a device that works by receiving signals from satellites.
These artificial satellites, specially built and launched to provide accurate location information while orbiting the Earth, are called GPS (global positioning system) satellites.

Publisher's Review
Misconceptions about physics
When we think of 'physics', the first thoughts that come to mind are misconceptions such as it is difficult, only geniuses do it, and it is a pure academic discipline that makes it difficult to get a job.
It is inevitable that seemingly difficult words like quantum mechanics and relativity have become ingrained in our minds as the representative terms of physics, and physics learned from textbooks seems incredibly difficult and boring, even from the terminology.
But are these prejudices true?
Indeed, famous and difficult physics theories have led to scientific revolutions, shifted philosophical paradigms, and ushered in a new era of civilization for humanity.
However, these theories are not established overnight, and changes do not occur all at once.
It was achieved little by little through observation and research that began with simple curiosity and accumulated to explain answers to past questions.
This curiosity and wonder begin with nothing other than the very small and trivial things we see in our daily lives.
Through countless thoughts and research to solve this problem, we were able to discover the laws of physics hidden in everyday life, discover new materials, and little by little reveal the origin of all things.
In other words, physics is a discipline that begins with human curiosity, before difficult scientific terms and complex theories.
The very act of wondering about everyday phenomena, such as how animals walk, how cars run, how cell phones work, and why it rains, and about everything we see around us, can be said to be the beginning of physics.
And the curiosity and exploration of many people have accumulated, and through repeated efforts over a long period of time, they have been resolved, and the results obtained in the process have led to the development of technologies that enrich humanity.
Physics can seem difficult and sometimes even mysterious, but it is ultimately a familiar and exciting subject.
Easy Physics, Exciting Physics
This book approaches physics in a way that even readers who find it difficult can find it interesting.
It covers the most fundamental concepts of physics through various topics such as walking, roller coasters, cooking, and smartphones.
It covers Newton's laws that can be learned through walking, or exercise; the law of conservation of energy and various forms of energy learned through riding a roller coaster; the basics of thermodynamics and changes in the state of matter, waves, time, and electromagnetic induction that can be thought of in cooking; and finally, the navigation function commonly used in smartphones, and the theory of relativity and quantum mechanics required to implement that function.
In this way, we will look at physics from its basics to its applications through common materials in our daily lives. Through this process, rather than learning techniques that can be applied immediately, we will help you acquire the principles of technology, the foundation for coming up with new techniques, and the ability to apply them again.
In today's rapidly changing technological civilization, the most important thing is the fundamentals.
To develop the ability to think, understand, and apply scientific methods, this book presents physics as a tool that teaches us how to look, how to investigate, and how to think.
At the same time, through the process of examining physics in action in everyday life, we can see that physics is not a difficult and distant subject, but rather a familiar and easily encountered subject in everyday life.
