✓ Popular content ranked #1 in Naver Premium content subscribers

Naver's premium content, "Chemistry for Everyone," explains numerous chemical phenomena encountered in everyday life in an easy and fun way.
The author explains difficult chemistry in a way that even those who are not familiar with it can easily understand, and adds humor to the writing.
As the author's serialization accumulated, the number of subscribers also increased and rose to number one.
As the support and interest of subscribers exploded, comments waiting for the author's book to be published lined up, and the book was finally published.
We have categorized the content published in various series by field, making it easy to find and read at a glance, including the chemistry of our body, the chemistry of emotions and psychology, the chemistry of medicine and food, the chemistry of everyday life, the chemistry of beauty, and the chemistry used in raising children.
At the end of each chapter, there is a Q&A corner with Gwangpaldosa, another character of the author, who answers various questions from readers in a spicy manner, satisfying readers' curiosity.


✓ No more being swayed by ghost stories, create a convenient daily life with chemistry.

Not long ago, an article titled, "Eating salty food doesn't mean you'll die early," was featured in one of Korea's leading daily newspapers.
When I see a newspaper article like this, I think, 'Wow! I can eat it saltier.
If you say, 'Salty is the truth!', it can have fatal consequences for your health.
A closer look at the paper reveals that the sodium intake of the subjects studied in the paper was only 60% of the average intake of our population.
In other words, this study has a problem in that the research subjects do not represent the average of our country.
It is very dangerous to be certain of something just by looking at the title of an article without considering the background.
The more ghost stories there are, the faster they spread among people, and some people blindly believe them without verifying the basis, which can even put their health at risk.
Unfounded rumors that getting the coronavirus vaccine will implant the virus's genes and brainwash you are spreading surprisingly well.
The more surprising or shocking the story, the more it spreads.
This book uses scientific evidence to correct misinformation and guides readers on the appropriate safety margin to distinguish between truth and fiction.
It provides facts about medicine and food that are poison if you don't know them and medicine if you do know them, everything about the three eco-friendly detergents, how to clean easily using chemical principles, the difference between natural and synthetic vitamins, whether collagen products really go on the skin, how Febreze gets rid of odors, substances that are dangerous to mix when cleaning, etc. in an easy and fun way, providing an opportunity to confirm the power of chemistry, its usefulness, and its strength.


✓ Approaching a healthy and happy life with everyday chemistry

Everything in our bodies is made up of compounds, and our behavior is governed by the presence or absence of small compounds like hormones.
Taking a drug, which is a small chemical molecule, prevents you from getting sick, but using drugs destroys the chemical circuits in your brain, leading to addiction and even ruining your life.
The alcohol in alcohol is also a chemical molecule, and the nicotine in cigarettes is also a chemical molecule.
When these chemical molecules enter our bodies, they interact with compounds such as proteins and DNA in our bodies, and even change our behavior.
If you get angry and your mind goes blank, you can recognize that your brain is secreting too much adrenaline and look away for a moment.
If you realize that constantly scolding your child increases the level of cortisol in their body, which makes them worse at studying, and can lead to obesity and depression, you may be able to choose a different parenting method instead of scolding them.
If we could just step back for a moment and remember that we are chemical beings when we feel like getting emotional and screaming, we would be able to objectify our actions and act more like mature human beings.
Through this book, you will not only apply useful chemistry knowledge to your daily life, but also reflect on your own behavior, taking you one step closer to a healthier and happier life.
