Today is the anniversary of the publication of the novel “Position of Love in the Equqtion”. Please enjoy the unique intellectual entertainment derived from the natural phenomenon (chaos phenomenon) that creates the world. Along with a fantastic story, you can also see the origin and necessity of “love” and “trials” in mathematical formulas. Knowing this mechanism is very important in life. It may seem difficult, but the only formulas are multiplication and subtraction. You can also skip the formula part and enjoy it ♬ You can also get it at your local bookstore, Amazon, or direct sales.
