1840 Indian Rebirth

Chapter 157 [Law of Conservation of Energy]

Headprint: "First of all, it is a decimal system, which is more convenient for recording and calculation. In contrast, imperial units do not even have a unified base system."

In fact, in this era, imperial units are not so stupid, or called anachronistic.

The main reason is that the measurement tools at this time are relatively rough, and the industry is not developed enough, and various measurement units are mainly used in the market.

For market occasions, the most important feature of the unit of measurement is that it is easy to divide. For example, binary numbers and hexadecimal numbers are very easy to divide.

The same is true for the ubiquity of sexagesimal, which is divisible by two, three, four, five, and six.

The replacement of traditional units by metric units is because with the development of industrial society, people's realization and requirements for precision are getting higher and higher.

"Okay." Gauss said nothing more, "Now is the next question, please prove the Pythagorean theorem."

Gauss felt that proving the Pythagoras theorem should be the insurmountable limit of this Indian.

The other artillerymen thought so too.

If it weren't for the identity of the captives, they might have ridiculed them undisguisedly in advance.

Even so, there is still a faint look of anticipation on their faces, as if they will soon see the embarrassment when the forehead lines cannot be answered.

However, what happened next was far beyond their expectations.

Lifting the forehead took a pen and paper, and completed the proof of the Pythagorean theorem without a word, a schematic diagram, just a few lines.

Moreover, a new method is used, and the simple and efficient proof is completed with the help of the area of ​​the right-angled trapezoid.

Gauss looked at the short proof on the paper, and his eyes widened in disbelief: "Who taught you this... this kind of proof?"

"Of course it's our great chief, the one who just left." He said with the forehead pattern, "I'm just an ordinary student of the great chief."

The proof method used for forehead lines is actually the "presidential proof method" of later generations, which was proposed by US President James Garfield in 1876.

Proving the Pythagorean theorem was no big deal to nineteenth-century people, but the novelty and simplicity of the proof earned Garfield some reputation.

It is obviously a bit of a miracle that the President of the United States can still win a good name by this. An Indian proposed this proof.

Looking at the proof in front of him, Gauss fell silent.

He realized that these Indians were really different, much more different than he had imagined.

"Okay... Now it's your turn to come up with a question." Gauss said a little unwillingly, he had a hunch that something might be wrong with him.

With a slight smile on his forehead, he started with a physics problem.

A simple application problem of the law of conservation of energy.

If you ask Ma Shao to evaluate this question, there is no doubt that it is: send a sub-question.

However, people in this era basically did not know the law of conservation of energy.

It cannot be said that there is no such thing. Strictly speaking, this law existed a few years ago.

But the law of conservation of energy at this time is not perfect and popular enough, at least it has not become one of the most recognized and basic laws of physics.

Top physicists know this law, but the gunner with the same name as Gauss is obviously not among them.

So when he tried to solve the problem, he just felt that his mind was muddled, and he didn't know where to start, as if it was an unsolvable problem at all.

He wrote a lot on paper and listed various equations, but after simplification they were all results like "x=x".

Gauss took a deep breath: "The questioner can't come up with questions that he doesn't even know. I think this should be a self-evident basic rule?"

He raised his forehead and nodded: "That's right."

Gauss asked again: "So, can you do this question?"

Forehead lines: "Of course, it's very simple... You admit that you can't solve this problem, right?"

Gauss was silent for a moment: "Yes...then, tell me your answer."

The forehead tattoo solved the problem in a few lines, and the result was: "This is the law of conservation of energy. In fact, if you pay more attention to the news of physics, you should have heard of it."

"Energy...conservation?" Gauss looked at a loss, unable to understand this concept.

However, this does not prevent him from checking the calculation and verifying the correctness of the answer.

"You lost, right?" He raised his forehead and smiled.

"I..." Gauss was speechless.

Several white artillerymen couldn't help saying: "No way, Gauss, you actually lost? Are you worthy of your surname?"

"God, you lost to the Indians!"

"Haven't you always been very sure about mathematics and physics?"

Gauss grabbed his hair and said distressedly: "I really don't understand this question... Conservation of energy? What exactly does this mean?"

"I'll do it!" The other artillerymen couldn't hold back and tried to solve the problem, but they were as confused as Gauss and couldn't get the answer.

The forehead pattern said: "White people, do you still think that we are illiterate and barbaric? Or, if we are illiterate and barbarian, what are you?"

Several artillerymen were speechless.

The mental blow is often heavier than the physical blow.

They can submit to the savages by force. In their view, the savages are like wild beasts, and human beings will not be ashamed of being defeated by strong beasts.

Now, however, these beasts, which had just defeated them in force, defeated them in mathematics and physics.

This makes them feel like they are broken.

"Arrogant but stupid white skin, your level of mathematics and physics is lower than I imagined, and you are not even qualified to be a student of the great chief!" Wei Wei said with contempt, he felt that this was better than killing the enemy with bullets more joyful.

Several artillerymen surrounded the question in silence for a long time, as if they were mourning their concubines.

Looking up Wen continued: "I hope your artillery skills can be higher than the physical level. If you don't even have a skill, you might as well do hard labor honestly."

"By the way, I'm willing to bet and hand over the ten dollars." He held out his hand.

"..." The artillerymen were still speechless, before saying after a while, "Where do we have any money?"

An Apache soldier immediately asked, "Why do you come to bet without money?"

"I..." The artillerymen opened their mouths.

Looking up, he glanced at his companions: "Obviously, they feel that they have a chance to win."

Then he said to the white people: "If you don't have money, you should make money first. The artillery director has a monthly salary of twenty dollars."

In the end, with mixed feelings, several artillery captives became artillery instructors at Fort Sutter, responsible for teaching artillery skills to Apache soldiers.

Naturally, there are feelings of humiliation and confusion, but it is also inevitable that there is some comfort and joy.

After all, a monthly salary of [-] dollars is really not low. Who can not be tempted to earn as much as he can?
