Section 1113 Mathematics teachers teach differently from physics teachers

Bai Hao couldn't figure it out.

Walked thousands of miles south from Qiongzhou, and then flew to the Tianshan Mountains, 5,000 kilometers is estimated to have?

So, how much error should this thing have?

Zhang Ju also sat next to him: "Factory director, is this accurate, or not." You give me a word! ”

Bai Hao sat cross-legged on the ground: "This, I personally feel it." Legend has it that the beautiful country has two meters, and the woolly bear is only half a meter, so no matter how bad we are, we should mix it into single digits. ”

"Okay, if you have something to say, you can do it." Zhang Ju wrote down Bai Hao's.

In fact, Bai Hao was really fooled.

Although it is 5,000 kilometers, going to space and not going to space are two different things.

Whether it is flying in the atmosphere or not, there is a qualitative difference.

This big guy flew at least eight thousand eight with a full tank of fuel, which was not enough for the temporary test, so it only flew five thousand two.

What Ding Lao said is correct.

Barely successful, the next step is to strengthen the sensation on the inertial navigation parts and reduce the cumulative error. Then assist the secondary guidance of the quiry, then the situation will definitely be different.

Cao Man is right.

Even if it is smashed, it will also be smashed out of a 500-meter pit, and that little error is not a matter at all.

To put it more bluntly.

Bai Hao only thought that this was an ordinary big guy, but in fact, the experiment was a big root prepared for the mushroom.

Bai Hao suddenly remembered: "By the way, why is there no air shield data?" ”

Zhang Ju shook his head: "I don't know, why don't you wait to go back to the factory and ask?" ”

Why is there no air shield data.

In other words, the air shield testers on the other side of the Tianshan Mountains will be covered in sweat.

Because their clairvoyance saw a blank slate, and when they found it, there was nothing wrong with them.

It can be said that in the ninth factory, some of Ah San's technical level is thrown out, and he doesn't know where he will fly to, and others can't know.

The difference is that the second half of the Ninth Factory can find its original way back by itself, and Ah San's one is basically completely lost.

The next day, Ding Lao received a report.

It is a very objective report, but in their opinion, theoretically they can't stop it at all, and no matter how they think about it, they can't find a way to stop it.

Ding Lao read the report carefully.

He understands. The fastest speed used in the barrage is five times the speed of sound.

Coupled with irregular movements, there is really no way.

So, go to the other extreme.

Ding Lao silently calculated it in his little book, and he believed that the speed of breaking through the atmosphere from space could be considered to be studied at Mach 15, or even Mach 20.

Fast.

Only fast enough, then Ying Xia Guo's ancient saying, the world's martial arts, only fast is not broken.

A small, brand-new, very interesting little thing was drawn by Ding Lao's pen at this time.

It is named after the ninth factory.

Harpoon Three.

This time, it's the real thing to test out the air shield and see how it works.

Let's talk about Bai Hao's side.

After returning to the Ninth Factory, he went headlong into the Universe Research Institute.

Technical things Bai Hao couldn't understand.

It doesn't mean that Bai Hao doesn't understand the meaning at all.

After going through all kinds of information for half a night, Bai Hao understood.

That big thing is based on the on-board version of the No. 9 Teng Snake No. 4, in other words, the car is changed to underwater, this set should no longer be called Teng Snake No. 4, it is completely a magic change, an almost crazy magic change.

The names written in the top three on the information are, Aszarevich, Ren Lao, and Flavi...... Kaido.

The auxiliary personnel, who can be called a champion, are close to ten.

Of course, the names of Ding Lao and others did not appear in the materials of the ninth factory.

It's early in the morning.

Aszarevich came and sat next to Bai Hao: "You are a genius, I made a small experiment after carefully watching more than 500 shots of various free kicks. ”

"What kind of experiment?"

"Follow me."

Aszarevich led Bai Hao to the next room, where there were three metal ramps.

"I have read the textbook of Xia Guo Primary School, and there is a sentence on it that the shortest distance between two points is a straight line, but the fastest distance is not. You see, a long time ago, there was a prototype of this theory, and the modern theory was first further studied by a Gallic scholar and applied to automobiles. ”

Three small iron balls are placed at the starting point, a straight ramp and two different curved ramps.

"How's that fast?" Aszarevich asked Bai Hao.

Bai Hao pointed to one of the curves and said, "This." ”

"Are you sure? Are you sure it's not the straight line this is the fastest. ”

"I'm sure!" Bai Hao gave an affirmative answer.

"You're a genius." Aszarevich conducted an experiment, and it turned out that the curve that Bai Hao pointed out was the fastest.

Aszarevich then said: "So, what you want to tell your sister is not a spiral, not a rotation, but the theory of the fastest curve." In your sister's words, when she was a child, her math teacher told her that the closest line between two points is a straight line. Now, physics tells her that the fastest is a curve. ”

Bai Hao really wanted to tell Aszarevich that what he wanted to talk about was the spin, the weird spin.

Aszarevich is telling Bai Hao: Bai Hao, you are a genius, it is you who make the end speed reach a new height, and the curve is more difficult to stop than the straight line.

Aszarevich continued: "Just now, I had a two-hour conversation on the phone with your sister's new teacher, the venerable Dr. Ding, and we wanted to try a new harpoon, which we named Harpoon III, and you can imagine that when we received the target for about a thousand meters, we split out the spines of three harpoons and crossed a beautiful arc in a perfect maximum curve. ”

"You see, suppose there are n points that may be blocked, the equivalent center of the circle is OJ, the minimum passing radius is RDJ, J=1......" Bai Hao was stunned, Aszarevich directly listed the equations, and then brushed a blackboard.

After the calculation, Aszarevich clapped his hands lightly:

"Perfect."

Bai Hao's head was full of symbols, and with his kind of scumbag, such a complex equation was written on a blackboard, and Bai Hao's eyes were spent. looked at Aszarevich with a blank face: "Old man, what do you mean?" ”

"Give money! It takes a lot of money to study this, and one experiment is hundreds of thousands of Xia Guo coins. ”

Porphyry, Bai Hao almost sprayed.

After going around in such a big circle and explaining the technique for a long time, I finally said this.

Aszarevich added: "Also, I personally suggest that the construction and expansion of supercomputing be accelerated, and the amount of computing in the next step is amazing, and it is no longer the time for Dr. Ding to use the abacus to calculate." ”

"No problem, money is not an issue."

It turned out that it was just to ask for money, Bai Hao breathed a sigh of relief and agreed very happily.

------Off topic------

Today add more.

A few days ago, the three alliance leaders gave rewards.

Thanks again.

Because of the manuscript storage, I owe it more.

I saved a little bit more, and today I added more tips for [Chop 6 Sauce, Zimu] book friends.

There is another one, who will definitely add more before the end of the month.

Thank you all for enjoying this book.
