The Mathematics of Relationships
The Mathematics of Relationships
Description
Book Introduction
Until we find the unknown variable called 'I'
About love relearned through numbers and formulas
The answer to every life challenge is found in mathematics.

This book, "The Mathematics of Relationships," is a collection of essays about a person in the middle of her life who breaks away from the coordinates she has been assigned as someone's daughter, wife, daughter-in-law, or mother, and sets her own unique coordinates.
The author was born the second daughter, a frail child, in a family with a wealthy family and relatively little expectation of a son.
It was only after the birth of his younger brother that his grandparents said, "Now you're a full five," and at that time, the child accepted '5' as a great number.
While living away from his working parents, the child learned to add numbers to numbers, grasped the calendar with the most numbers among the objects in the house, and understood the concepts of multiples and multiplication.
In my own world, I opened my eyes to the world of 'numbers'.

The book unfolds a journey that begins with 'me', looks back at 'my surroundings', and returns to me again over four chapters.
Chapter 1, 'The Birth of Perfect Numbers', contains the author's story of birth and his first encounter with numbers during his childhood.
He chose marriage as a "perfect solution" to escape from the family atmosphere that values ​​boys, his father who was a freeloader, and his mother who had to run the household alone, but he realizes that married life was a time of enduring unwanted entanglements.

In Chapter 2, “Coordinates of Role,” the author, who is both a child and a parent, ponders the coordinates of parenting and childhood in Korean society as he experiences Children’s Day and Parents’ Day, which come every year.
In Chapter 3, 'The Identity of Seafood Kalguksu', we solve the mathematical elements encountered in everyday life and the identities encountered in the absolute world, and in Chapter 4, 'The World Seen from a Twisted Position', we learn that patience and love are the most necessary things for 'expanding relationships', and we end with the process of returning to ourselves.

Before Solving | Mathematics Was a Process of Relationships and Love

1.
The birth of perfect numbers

Finding the price of Dad's free ride
Harmony of friendship
The first number I encountered in the world
A relationship that is neither dependent nor independent, taming

2.
Coordinates called work

Parent-child seat change
A mother's love resembles a convex quadratic curve.
The love of a circle seen from afar
The tilt of the umbrella and the tilt of the mind
The change in the direction of movement, that child's fall
The love of complex numbers that transcends space
The expansion of the world and the transition of generations

3.

The identity of seafood kalguksu

The number of cases where you absolutely have no choice but to get sick
Even if the function value changes, I am still me
The formula for emptiness and fullness
The identity of seafood kalguksu

4.
The world seen from a twisted perspective

When the slope of pride becomes gentle
A change of perspective on uncomfortable people
The escape formula shouted from the fire pit
Experiencing the loss of cones and pyramids
The mass of trial and error, the density of ripeness
Me and my inner child on parallel lines

After solving | The moment found in an infinite straight line

Into the book
Math didn't ask much of me.
They didn't even give me information.
It stimulated my curiosity that sometimes burst out, strengthened my inner self, and allowed me to see true beauty.
Sometimes we become friends.
Isn't life worth living like this?
After spending a long time with mathematics, the relationships and values ​​that had been so heavy became a little lighter.

--- p.13 From "Before Unraveling"

Numbers, which have been with me since birth, have expanded my perspective, which was previously limited to mere numbers.
Values, views on nature, methods, means, and even emotions.
Numbers were always with me at every moment.
It is an enlightenment that has come a long way.
Today, too, I live by connecting numbers to life and nature, and incorporating them into my daily life.

--- p.36 From "The First Number Encountered in the World"

Euler's identity relates to a range of numbers that extends beyond the world we exist in and deep into our consciousness.
The identity 0 for addition, the identity 1 for multiplication, the irrational number π, the imaginary number i that exists in the complex number range beyond the real number range, and the irrational constant e, all have the beauty of symmetry and balance in their shapes.
(Omitted) The ties that went back to my grandparents were painful.
The love my parents gave me was so consistently beautiful that it could sever this painful string.

--- p.92 From “Expansion of the World and Generational Transition”

The cone-shaped sense of loss and the pyramid-shaped sense of loss such as the triangular pyramid and the square pyramid cannot be compared in terms of volume and quantity that exist in reality.
Considering that the inside and outside dimensions of the volume are roughly the same, the weights are also incomparable.
The amount of moisture (and best effort) contained within it is incomparable.
The mathematical language conveyed by the colorful horns is that 'the sense of loss is different in each shape, but it is impossible to know which is bigger and heavier.'
(Omitted) The sense of loss must ultimately be endured with the whole body.
Even if it falls sharply, it must hit as it is.
This way, you can fly at a steeper angle.

Publisher's Review
Like a 'circle' connected to points at a constant distance from the center
May we all be able to love each other, neither close nor distant,
Comfort to all the unknowns struggling with relationship anxiety.

The relationship between people begins with acknowledging that [x]+[y]=2.
The relationship is maintained only if we accept that [x]+[y]=1 cannot be true.
We generally believe that when two lovers tie the knot, the latter of the two is the most likely.
The reason why May 21st is designated as Couple's Day during Family Month is to remember that this is the day when two people become one and to cherish and love each other more.
However, I think the former holds true in relationships.
_'A change in perspective on uncomfortable people'

Perhaps all conflict in relationships stems from a refusal to acknowledge that “[x]+[y]=2.”
'I' and 'you' can never be the same, and the illusion that 'two become one ([x]+[y]=1)' does not exist.
No matter how much I love you.
The author says, “Whether it’s a close or distant relationship, the line between the two is always parallel.”

The relationship that most resembles this is the love of 'Circle'.
The author, while transferring the equation of a circle to a coordinate plane over 30 years ago, discovered a consistent and unchanging love in this graph.
To myself, it is parental love, especially mother's love.
And I promise.
Just like a circle with a certain distance from the center, I will love my family and those around me from a distance that is neither too far nor too close.
The love of the circle may seem like it is seen from a distance, but it is neither hot nor cold, and is a love that can maintain the relationship between people peacefully like parallel lines.

The classic kalguksu dish made with sincerity instead of seafood.
Pi discovered from falling cherry blossoms…
The richness of mathematics applied to everyday life and connected to nature

This book is filled with the warm mathematics that permeates everyday life and nature, and the language that mathematics conveys.
One spring day, while walking along a cherry blossom road with my daughter who was feeling hurt, I taught her 'Euler's identity' and she was amazed at how aesthetically beautiful it was, even though she didn't know the meaning of the symbol.
On the other hand, when the family goes to a seafood kalguksu restaurant with difficulty, they see kalguksu with no seafood whatsoever, and in that place, they find an equation that substitutes the 'sincerity' of the kalguksu restaurant owner.

Another identity that defines the author is that he has been teaching mathematics to students for over 20 years.
Although I am not a mathematician or a math teacher, math, which was a subject of play and learning in my childhood, has now become a subject of teaching.
The goal is to teach mathematics to young people as a way to “build relationships” in their lives, beyond mathematics in the curriculum.
For those seeking to find the unknown called "self" in a world filled with variables, the equations presented in this book will be of great comfort.
