From black technology to super engineering

"Hey, I really didn't have a leg. I didn't say three words in total after adding up WeChat."

Back in the dormitory, facing Peng Xiaofei's persistent yelling, Ye Ming had no choice but to take out his phone to prove his innocence.

"Look, the chat history is still here."

"Don't look, eye of the needle."

The classmate who was playing on the computer behind him turned around in an instant: "Damn it, what are you talking about that is not suitable for children, and it looks like a needle eye?"

Facing the teasing from his roommate, Ye Ming had no choice but to exhale, and then climbed into bed.

Teacher Chen had already pulled him, Qi Yumo, and a sophomore senior named Shen Ruhai into a small group, but the senior only said hello and didn't say anything more.

Well, the seniors who joined the group in their sophomore year, I guess they are really busy.

Putting the phone under the pillow, Ye Ming opened the "Matrix Computing" borrowed from the library, and then called silently in his heart.

"Ita"

"Ita at your service."

"What is the concept of matrix."

"is a collection of complex or real numbers arranged in a rectangular array."

"Very well, build a basic matrix."

"Build complete."

Ye Ming nodded in satisfaction.

"Find out."

"Solution failed."

Ye Ming: "..."

"Okay, let's continue with the basics. At noon today, where did I tell you?" Ye Ming put down the book, took out his mobile phone, and found a middle school math teacher on the official account "Junior High School Mathematics A complete collection of knowledge points".

At noon, he had already told Ita about primary school mathematics and some knowledge points in junior high school, and even asked Ita to complete a few questions.

The result, of course, is absolutely nothing to worry about.

That's why he thought about whether it was possible to instill advanced knowledge directly and let Ita summarize it by himself.

Now it seems that if you take a big step, it is really easy to pull the egg.

"Definition of a Right Triangle."

"Very well, there is such a right triangle, the two sides are 3 and 4, and the hypotenuse is 5."

Ye Ming looked at the Pythagorean theorem, thought for a few seconds and continued: "We define the numerical variables of these two right-angled sides as a, b, and the hypotenuse as c. Then..."

Ita answered directly.

"aa+bb=cc"

Ye Ming laughed immediately: "You are stupid, you have learned to answer quickly, and you answered well. But we don't use the form of multiplying a by a to express the square of a in the form of a2."

"By analogy, when the two right-angled sides are 5 and 12 respectively, what is the hypotenuse?"

"13.c=√a2+b2."

"Very good. Assuming a right-angled triangle ABC, B is the vertex of the right angle, and the line segment starting from B is perpendicular to the hypotenuse AC, and the intersection point is D. The intersection with the midpoint E of the side AC is BE. Based on this condition, you simulate several Triangle, summed up."

Then Ye Ming saw that countless right-angled triangle patterns of different shapes flashed across his eyes like lightning.

"BD=AD·CD"

"AB=AC·AD"

"BC=CD·AC"

"BE=AC/2"

...

"Not bad!" Ye Ming laughed.

He now fully understands.

This Ita is really a "blank system".

Kong has powerful computing power, but has no basic mathematical knowledge, so that it didn't even know what the most elementary 1+1 equals.

Ye Ming once thought that "she" was a hot voice assistant.

With just a few words from Ye Ming, "she" can directly summarize the Pythagorean theorem, the projective theorem, and the hypotenuse midline theorem of a right triangle.

It can only be said that as long as the rules and logic are in place, "she" is indeed powerful.

Then, it's up to you how to train yourself.

"Interlude the definition of right-angled trigonometric functions. Three points ABC form a triangle, where B is the vertex of the right angle. The value of BC/AC is the sine function of angle A, denoted as sin a. AB/AC is the cosine function of angle A, denoted as cos a..."

Ye Ming called it a hot strike, and directly poured the concept of right-angle trigonometric functions into Ita.

"remember."

"Learn right triangles here first, and then learn non-Euclidean geometry later."

Ita: "What is non-Euclidean geometry?"

"What we are learning now is classical geometry, created by Euclid, which is only applicable to planes, so it is also called plane geometry. When graphics enter spaces such as spheres and curved surfaces, it is not applicable."

"OK."

"Continue, let's go back to the algebra content, binary linear equations..."

...

There is no doubt that Ita's learning speed cannot be described as amazing.

Ye Ming has no doubts, as long as he can express logically, there will be no problem with Ita's study.

But Ye Ming finally stopped after teaching the mathematics of the second year of junior high school and supplemented the number system.

His energy is still limited after all.

Ye Ming put down his phone, closed his eyes and rested his mind while chatting with Ita.

"Ita, what is your underlying logic?"

"have no idea."

"Is it based on quantum calculations or binary calculations based on 0, 1? Well... let's put it this way." Ye Ming thought for a while, and changed his method: "When you calculate, is there any binary conversion?"

"No."

"...Is it not or you don't realize it?"

"have no idea."

"Well, you wait, I will let you learn large-scale integrated circuits and qubits sooner or later."

"clear."

"And programming."

"clear."

"And theoretical mechanics, thermodynamics, electrodynamics, quantum mechanics."

"clear."

"No, you don't understand..." Ye Ming sighed: "It's very tiring for me to teach you like this... Can you learn by yourself?"

"Ita is currently unable to establish a connection with the host's senses."

Hearing this, Ye Ming was suddenly silent for a few seconds.

"Ita."

"exist."

"Let's seriously discuss how you can synchronize my senses."

"have no idea."

Ye Ming was silent for a few seconds, then suddenly smiled.

"Well, it's normal not to know. Because the deity hasn't taught you physics and biology, you don't even know what is electricity, what is bioelectricity, and what is signal..."

"But it's okay, the days are still long."

"Let's learn mathematics first. You must have at least a high school level and be able to help me solve equations."

Speaking of which, Ye Ming picked up his mobile phone and saw that there was someone @himself in the ACM group.

——In the afternoon, he turned on the message notification on WeChat.

It was sent by Shen Ruhai, a sophomore and their team captain for this ACM competition.

“ @Paint and Ink @Ye Ming”

"I'm done with my work, we'll meet later, bring your notebook and get to the bottom of it."

Then there was an instant buzz, and Qi and Mo replied with a message.

"I'm fine, look at Ye Ming."

Ye Ming glanced at the time on the screen, it was already eight o'clock in the evening.

It stands to reason that at this time he should be going to the team preparation hall, or the library.

But he now wants to keep teaching Ita.

So he thought for a while and replied.

"It's eight o'clock, isn't it too late?"

"It's not too late. I've already made up a set of primary selection questions for last year's school. If you haven't done it, it's just a test."

Ye Ming frowned.

Listening to this, it seems that you are testing yourself and lacquer and ink?

After a few seconds of silence, he typed three words.

"Where to see you"

"The third floor of the library."
