Some people say that you are stupid. What does this mean?

first: 2 is sometimes used to describe a simple-minded person who acts foolishly.

second: 2 Arabic numerals are natural numbers between 1 and 3, the smallest and the prime number

third: of course, sometimes it can also show that a person is unique, stylish and cute ~ there is a saying that "very 2 is very radiant"

fourth: 2 has two meanings, one is positive, the other is negative, and positive means that this person is simple and foolish. If an integer is divisible by 2, it is called an even number. For integers written in even decimal system, such as decimal system and hexadecimal system, to judge whether it is even, we only need to judge whether the last digit is even, while binary system only needs to judge whether the last digit is .

2 is the smallest and the first prime number (also called prime number), and it is the only even prime number. The next prime number is 3. Because there is more than one factor, it is also a highly composite number, and the next highly composite number is 4.

2 is the third Fibonacci number and the first positive prime number in Fibonacci series.

2 is a unique Supronik number.

2 is the smallest number that can be decomposed into the sum of two nonzero complete squares: 2=1+1

The order of the simplest nontrivial group is 2-that is, the remaining group of 2.

quadratic function: y = ax 2+bx+c (a ≠ , a, b, c are constants) quadratic function called x

quadratic curve: also known as conic curve, is the most thoroughly studied curve in history except for straight lines.

Quadratic equation: the lowest order nonlinear equation with general solution formula.

dihedral group: the simplest finite generating noncommutative group

antinomy: if two propositions contradict each other, then one of them must be wrong.

Quadratic reciprocal law: one of the most profound theorems in classical number theory, discovered by Gauss. [edit this paragraph] for any number of p p+p=2p, the addition becomes multiplication

p>pp = p↑↑2, the multiplication becomes power

PP = p = p = p = 2, and the power becomes the smallest body with two elements. The arithmetic square root of

2 is the earliest irrational number discovered. [Edit this paragraph] The atomic number of helium in science.

composition of two forces: if the effect produced by one force is the same as that produced by the interaction of two forces, this force is called the resultant force of those two forces, and finding the resultant force of these two forces is called the composition of forces

Conditions for the balance of two forces: if two forces acting on an object are equal in magnitude and opposite in direction, and are on the same straight line, these two forces are in balance with each other

Newton. [Edit this paragraph] In other fields, Europe, South Africa, the Middle East and Japan are represented in the DVD area.

year: 2 years, 2 years BC, 192.

idiom: you can't do two things at once.

philosophy: dualism and dichotomy.

organism: diploid, that is, an organism with two chromosomes in its somatic cell, such as human. [Edit this paragraph] The number 2 is the most active in nature. It always appears in the natural science we study and in our lives.

chemical formula: the chemical formula of many elemental gases on the earth is X2,

that is, it consists of two X

atoms. O2,N2,H2,Cl2,F2 ... many, many.

there are many things in our body that also appear in pairs. From top to bottom, you can also find a lot:

brain: left brain VS right brain.

eyes: left eye VS right eye.

hand: left hand PK right hand.

There are too many examples like ............

to sum up, 2 is a very balanced number! If there is no opposition between left and right, I'm afraid people can't even stand still.

2 is still symmetrical. A piece of paper folded in half presents us with two identical worlds, whether insects or mammals, the number of legs must be a multiple of 2, otherwise how can they survive? The mirror also shows us two congruent worlds.

Some grammars in English embody some special meanings of 2. For example, I already have two apples, and if I want the third apple, I have to use second ......

So, 2 also represents another meaning: extra, others.

2 is a fence from singular to plural.

have you ever wondered why two people should fall in love? Two people, in each person's subjective consciousness, live with "I" only with a "TA", which will add a sense of security to love in one person's eyes. Imagine, if three people kiss, each person must kiss twice, and it takes three times in total. Are you tired? Two people always need to kiss once, which is the best choice arranged by God for human beings.

after all that has been said, why can't three people get married? Because there are only two sexes of human beings! (The shemale is not included). According to pigeonhole principle, if two sexes are regarded as drawers and three people as objects, then there must be more than two people of the same sex.

By the way, the "2" given by God has two genders. If there are three sexes in human beings, it is worth discussing to reproduce ................................................................................................................................................................ There are many opposites in nature. There are two kinds of magnetic poles, N and S, two kinds of Male and Female in gender, two kinds of charge,+and-,and even matter can be divided into two kinds, positive matter and antimatter (which may be a bit far-fetched). There are still binary stars in nature, and there are yin and yang fish (the symbol of Taiji) in China, positive and negative, north and south, and many, many, many, many, many, many, many, many, many, many, many, many, many, many,

Think about the computer you are using. The computer uses binary because the circuit has two states: connected and disconnected (short circuit is connected), that is, the current is divided into two states, yes and no, and the computer is made up of these little ones and zeros.

Zhao Benshan used 2 to replace fools and idiots. However, is this world still like this without the wonderful "2"?
