Hogwarts and the Unspeakable

Chapter 114 1615-1690: Britain and the East

"You must have learned derivatives, right?"

Dragonborn asked first.

Allen grinned inwardly.

Not only had he learned it, but he had learned it well - but he had forgotten it.

New curriculum standard for high school mathematics elective one, conic sections and derivatives.

Normally, this is the mathematics finale question in China’s new curriculum standards.

The two questions total 40 points.

The total score of the new curriculum standard for the college entrance examination is 750 points.

Forty points doesn’t seem like much.

However, anyone who has experienced the college entrance examination knows that a mere 40 points is the difference between 985 and 211.

----

it's a pity.

Obviously I have worked very hard to learn the knowledge of "derivatives".

But if you don't use it for a long time,

Alan Appleby still gave this knowledge back to the "math teacher".

Only a little bit of relevant knowledge about "the geometric meaning of derivatives" and "analysis of derivative functions" is left.

I'm afraid there aren't many left.

----

However, what may be surprising is:

Derivative theory was created 400 years ago.

It is generally believed that the Newton-Leibniz formula played an important role in history and was proposed in 1677.

----

1677, what kind of time is it?

First of all, it belongs to the mid-to-late 17th century.

When talking about this period, we cannot help but talk about a major event that happened during this period.

In 1640, the British bourgeois revolution broke out:

In 1642, the English Civil War broke out.

In 1645, Cromwell formed the "New Model Army".

And just four years later,

In 1649, King Charles I of England was guillotined.

He became the first emperor in European history to be publicly executed.

In 1653, Cromwell proclaimed himself "Lord Protector" and established a military dictatorship.

What happened later is more famous.

In 1688, the "Glorious Revolution" palace coup broke out in England.

In 1689, the Act of Powers was signed.

(I suddenly remembered that a long time ago, the history teacher repeatedly emphasized to us how to write "power" in the "Bill of Powers")

----

In just a few decades, so many things have happened in the UK.

It can't help but give people a sense of vicissitudes of life.

1640-1689, a total of fifty years. half a century.

If a person was born in 1640, he would actually be 1689 years old in 49.

Time seems to be very slow, but in fact it is also very fast.

He can see all this.

Just one generation's time.

----

In 1643, Isaac Newton was born.

----

How interesting.

So many things happened in the 17th century.

When you think about "Isaac Newton" and "Cromwell" living in the same turbulent era.

It just makes people "cry".

This is especially true when you consider that "1648" was the end of the Thirty Years' War.

----

And when you think back,

April 1618, 4, in the far east.

Nurhachi officially complained to heaven with the "Seven Great Hatreds".

When declaring war on the Ming Dynasty.

It can’t help but give people a feeling of “the world has changed forever”.

No one knew at the time, just thirty years later.

1644, the year after Isaac Newton was born.

"China's Qing troops enter Beijing."

----

This is the end of the review of history - if we continue to review it like this, this novel will become a "Historical Random Notes".

The author has said so much, and the message he wants to convey is very simple:

Incredibly simple.

----

this world,

The world we live in.

How vast it is!

How insignificant!

----

How small the world is!

Every person, every thing, every piece of information is connected together!

It's like what we now call 1643.

The entire earth, just like this, is connected by a simple number.

1643.

When you say 1643.

The whole world is in 1643.

Whether it was the birth of Isaac Newton,

Or will Charles I be guillotined.

Or the upcoming Qing army entering the pass.

All happened in such a magical year.

----

However, the world is so vast!

It can accommodate completely different histories, cultures, languages ​​and ways of living.

As big as that, if we don't talk about 1643.

The British bourgeois revolution and the "Qing army's entry into the country" seemed to take place in two unrelated worlds.

----

The world is connected in this way.

Whether civilizations are connected or separated from each other.

How cruel!

How callous!

How heartless!

But, how "just".

----

We also talked about "time and space" in the last chapter, which is similar to "physics" knowledge.

But now we are talking about "Britain and China in the 17th century."

Isn't it a big span?

Not big.

Because we live on such a vast earth!

Just like what this poem says!

----

"Everyone is united,"

“Nooneisanisland,”

"entireoritself,"

“soneveraskforwhomthebelltolls“

“Ittollsforthee.“

——John Donne (1572-1631) "Forwhoonthebelltolls" (with changes)

----

This poem was later adapted into a novel by Hemingway:

"For Whom the Bell Tolls"

----

Yes!

Everyone is connected.

No man is an island.

In fact, it’s not just people.

This is how information is connected.

This is the basis on which human conceptual systems can be built.

The human consensus based on this conceptual system has formed today's human society.

It also allows us to become who we are.

"The Magical World", "The Nature of Time and Space", and "The History of England and China in the Seventeenth Century".

There is actually an obvious connection!

That is, they both belong to human knowledge.

They all belong to the grand scheme of the "human concept".

We seem to be talking about some unrelated concepts.

However, in fact, they all exist within this knowledge "diagram".

Just one in the first line of page 17,

The other one is just in the first line of page 117.

----

When we cast our sights on the entire human existence,

Earth’s history;

The evolution and decline of human civilization,

And when it comes to human knowledge graph.

You will find that

Between "information about time and space" and "human history",

in fact,

It's connected!

----

From this perspective, a world with so-called “too many elements” is built.

It's in line with the normal state of the world.

----

"Learned without a doubt."

Snape nodded.

"Whether it's the 'advanced configuration' of transfiguration or the 'advanced chemistry' of potions,"

"They all need 'advanced mathematics' as a foundation."

"And of course I also did lots of exercises."

-

"I've learned it too."

Allen just mentioned it briefly.

"But I kind of forgot about it."

Allen planned to see what the Dragonborn said before making his own speculation.

But the Dragonborn himself was here, and Allen couldn't explain his conjecture in a flawless manner.

----

"Ok."

"Although I really want to tell you a lot about 'configuration'."

"But the current conditions don't allow it."

"simply put,"

"When I draw pictures and write calculations, I have to write on at least two blackboards."

The Dragonborn shrugged.

----

"So, I will tell you the situation here straightforwardly."
