The world is abuzz with chat GPT.
Because it shows the possibility that artificial intelligence can replace human intellectual ability.
When I see things I could only imagine becoming reality, I am truly amazed at the advancements in science and technology.
But looking back, such amazing experiences have always occurred throughout human history.
Every time a new discipline emerged, such as Copernicus' heliocentric theory, Newton's classical mechanics, or modern physics based on the theory of relativity and quantum mechanics, humanity expected a rosy future.
In that sense, the artificial intelligence technology we are experiencing now may be just the prelude to a new era.
This is because in the near future, new science and technology will emerge based on groundbreaking advancements in life sciences as well as information technology, including artificial intelligence.

In the future, a new era of science and technology will begin, where information and life sciences will converge, and artificial intelligence will be able to solve most problems.
Because new technologies are so unpredictable and raise questions about human identity, they sometimes seem to bring more anxiety than hope.

What skills do people need to survive in this era? Shouldn't they at least be able to design their own problem-solving methods? How can we cultivate these skills and grow into leaders who can lead the future?

We need to go back to basics.
We must not be intoxicated by the superficial appearance of modern science and technology, but delve into the essence of science.
Physics, in particular, is a discipline that deserves even more attention because it constitutes the essence of modern science and technology.

Bridge Gifted Learning, which turns curiosity into skill, and Unfamiliar Physics Class were written for elementary school students and above who are interested in science.
I wanted to change the unfortunate reality where elementary school students who were very interested in science, including physics, end up thinking of science as a difficult and boring subject as they enter middle and high school.
So, I tried to convey the essential content in an easy and fun way, and I organized the book so that after reading it, you can naturally get a big picture of physics.

I hope this book will serve as a bridge to deeper science beyond elementary science, and as a guide for students who want to properly study the fundamentals of physics.
So, I hope that this book will be of some help to students who read it and grow into excellent scientists.
