You have to know science to know the future.

Modern science and technology are blossoming in various fields based on the basic scientific research that was established in the 19th and 20th centuries.
Robots are dancing and playing the piano, 3D-printing houses and autonomous cars are being produced.
Its achievements are endless to list, and because they are deeply related to our daily lives and economic activities, they are widely covered in the mass media.

In order to live in this era and not be left behind in knowledge and information, it is necessary to have a certain level of scientific knowledge.
Science has become a necessity, not an option.
The ability to read the big picture, based on science, to understand how the things we use are made, how they affect our bodies, and what ripple effects they will have on our society is increasingly needed.
Therefore, the science of the 19th and 20th centuries, which became the foundation of modern science, that is, the science learned in high school, is emphasized.
This book explains the concepts of the foundations of science from the perspective of 'laws, principles, and formulas.'
It is not a superficial explanation of terms, but rather it is explained repeatedly from various aspects.
We also introduced where the laws and principles are used to help you understand them more specifically.
I hope that through this book, you will solidify your fundamental scientific knowledge and keep up with the rapidly advancing science and technology.

Features of this book

A comprehensive overview of high school physics and chemistry concepts in one volume.

Today, understanding the laws, principles, and formulas that are famous in the history of science is very important, regardless of whether you are in the sciences or the humanities.
Even to understand modern science, the outstanding wisdom of science discovered up until the early 20th century is absolutely necessary.
Most of the content that forms the basis for this is what you learn in high school science classes.
This book summarizes the laws, principles, and formulas of physics and chemistry learned in high school science classes and includes examples of how each concept is actually applied.
If you make it a habit to refer to this book like a dictionary whenever you need it, it will become a compass for understanding modern science.

Discovering the laws of science in everyday life

Although it is a dictionary, it is structured to be easy and fun to learn, breaking away from the rigid dictionary format that is commonly thought of.
In particular, it helped us understand how physics and chemistry, which we learn in science class, are applied to our daily lives by explaining them with fun pictures.
From the power that moves scissors, staplers, and bicycles to the principles that drive rockets and yachts, you can easily understand the principles of science by approaching them in a friendly manner using elements that are commonly found around you.

Explore deeper through practical problems and columns.

It is designed to help you understand the concepts more deeply through practical problems of various contents, rather than just explaining the concepts of laws, principles, and formulas.
Additionally, at the end of each unit, interesting topics such as 'Learning about electricity and batteries through home appliances' were selected and organized in column format.
Based on these contents, if you study the basic scientific concepts in this book step by step, from basic to advanced, you will eventually see the principles and structure of modern science and gain the power to foresee the future of science and technology.
