Special Appendix: Past Exam Questions

This book is a textbook for the 7th grade technical civil service examination, patent attorney examination, and promotion examination.
It can also be used as a textbook for first-year college students' introduction to physics.
I dare say that this book not only explains the major theories of physics more clearly and easily than any other textbook, but it is also structured so that the acquired concepts can be systematically applied to real-world problems.
The reason is that I completed each sentence as if the readers were sitting in front of me.

One of the unique features of this book is that it thoroughly analyzes past exam questions and organizes them into separate volumes by chapter, covering mechanics, thermodynamics, fluid mechanics, electromagnetism, wave theory, optics, and modern physics.
Each problem is accompanied by a detailed solution, including analysis of the problem's requirements and applicable formulas, so that you can immediately apply the theories you have learned to real-life situations.

Physics has many formulas to remember, so learning methods often involve simply memorizing formulas and solving problems.
This is not only a misconception about physics, but it is also a countermeasure that is completely incompatible with the recent trend of concept-based exams.
Considering that physics is a discipline that describes phenomena, students should first focus on clearly understanding the basic concepts.
Additionally, we must focus on understanding the core principles and laws that physics is trying to convey through various formulas.
This is something that matures as you actively engage with various problems and repeatedly think about the principles/concepts.
This attitude will also help you study other major subjects.

I hope this book will be of help to all of you taking the exam.
I have done my best to ensure that this book is a complete theoretical preparation for the exam, but I believe there are still many shortcomings.
We promise to create a more complete book by incorporating and collecting readers' opinions in the future.

Finally, I would like to thank CEO Song Ki-su for his groundbreaking ideas and support, such as two-color printing and separate volume composition; Director Kim Myeong-shin for his amazing work; Manager Gongyeopseo for his patient editing of the long-term project; and my beloved wife and children for their emotional support.
