Who is eligible to have triplets?
To have a certain economic foundation,
And you must have a second child to qualify for a third child.
(Giving birth to three children at a time is not triplets, but triplets)
If you have only one child or no children,
Of course, you are not qualified to have three children.
Others don't want to have children or even get married.
It's no use letting a few babies go
So how to convince them with mathematical principles?
Let's start with "exponential explosion"
The most famous story about the "exponential explosion" is that wheat is playing chess.
Ade (Archimedes, not Andy Lau) invented chess, which made the queen very happy.
She decided to reward him: Ade, Allah is very interested in you!
(The Queen may be a mixed-race Shanghai-Guangdong)
What reward do you need?
Ed said, "Percy, don't be with me,
(Archimedes is from Nanjing? )
I don't want your reward, as long as you reward me with some wheat on the board.
Put 1 in the 1 grid and 2 in the second grid.
The third box contains 4 capsules, and the fourth box contains 8 capsules.
By analogy, in the future, the number of wheat grains put into each grid will be twice that of the previous grid.
Just fill in 64 boxes. "
A small part, a few grains of wheat, what's so difficult,
"Come," the Queen paid Adebayor in full.
The work of counting wheat grains began.
The first box contains 1 capsule, the second box contains 2 capsules, the third box contains 2' capsules, ... The twentieth box has not been put yet.
A bag of wheat is empty. Bags of wheat were carried away.
However, the number of wheat grains is increasing rapidly one after another.
Even if she takes out the national grain, she can't keep her promise to Adebayor.
The original total number of wheat grains required was1844674073709551615.
How much wheat is there?
For example, if you build a warehouse to store these wheat,
The warehouse is 4m high and10m wide.
Then the length of the warehouse is equal to twice the distance from the earth to the sun.
It takes two thousand years for the world to produce so much wheat.
Rich as the country is, he can't get that much wheat.
This is the power of exponential explosion!
History is woven by the lives of countless people.
The wheel of history is always turning,
Everyone will eventually become the dust of history.
After 360 years, how will people know you exist?
Go down in history or have a baby.
The latter is obviously easier.
It is assumed that 10 generation can be transmitted in 360 years.
(No accident occurred during the period)
So, the tenth generation has your lineage, namely:
1 vs 59049, which celebrity is more likely?
The answer is obvious!
Having a good theoretical foundation to have three children certainly requires a certain economic foundation.
The average cost of raising a baby is about 6.2 million yuan1.98 million yuan.
If the number of affluent people will reach 1, 632,430,000 yuan,
If the number of children raised in these places needs to be increased,
Raise three more, and the number will be tripled!
(Some mathematicians think that the multiple will be less than 3,
They think the boss's clothes and pants can be worn by the second child and the third child.
The cost in this respect can be saved,
But the third is the youngest, usually naughty and a "debt collector"
Probably cut my brother's underwear with scissors,
In this way, you have to buy clothes and pants again, and the cost will increase, so the average multiple is still 3)
A welfare system with an open policy but no corresponding improvement,
The popularization of "Sansheng" has a long way to go.
Canada's "milk gold" policy can be used for reference.
"Milk gold" is the most generous welfare in the Canadian welfare system.
Giving birth to a child in Canada not only costs money, but also "earns" money.
This benefit will be adjusted according to the change of family income in July each year.
Starting from July, the maximum annual milk subsidy for children under 6 years old is 6,765 Canadian dollars.
Children aged 6 to 17 can receive a maximum of $5,708 per year.
Besides, this benefit is tax-free.
Take a family with parents' annual income of $654.38 +0.2 million and three children under 6 as an example.
You can get $9350.52 in milk money this year, which is nearly $780 a month.
But if parents earn 200,000 Canadian dollars a year, the milk fund will have less than 3,000 Canadian dollars left.
However, if parents' annual income is $80,000, milk money will rise to $65,438+$02,550.
(Simple and practical mathematical modeling has solved big problems)
So the rich and the poor dare to live!
You know, not everyone in China can meet the standards of Zhang Yimou.
