Road to science and technology

Due to signal transmission delays, it took Purple Planet about half an hour to see this live broadcast and conversation.

At this time, the top scientists from the three powerful countries gathered together. This was the moment they had been waiting for ten years.

But no one expected this to be the case. They had actually imagined what this cuboid was ten years ago, because a detector had already captured it at that time.

At that time, some people thought it was an alien civilization weapon, some thought it was something left by aliens to test them, and some thought it was an object containing the knowledge of alien civilization. Some alternative people Then I thought it was just a simple metal cuboid.

Now they understand that this is indeed a metal cuboid, but it is not an ordinary cuboid.

"We use our most advanced processing technology in the Great North to process an object. After magnifying it ten thousand times, you can clearly see the lines in it. It is hard to imagine what kind of technology this is a cuboid processed by. The surface is absolutely smooth!"

Said a scientist from the North Country, who was obviously a man of advanced technology even for his country.

"Is there really something absolutely smooth?" The scientist next to him muttered to himself in confusion.

"Isn't that what it is? This cuboid!"

His muttering was answered by someone, "According to the latest information, the edge formed by the angle between the two faces of the cuboid is extremely sharp, and its cross section still has no bulge at all."

This is obvious. No matter how many grindstones are used to sharpen a general knife, its sharp edge will still look like a jagged edge under a magnifying glass.

At this time, the door of the room where scientists and researchers were located was pushed open, and a sulfur-based lifeform wearing a tag on its head walked in. As soon as he entered, he asked: "Can we transport it here?"

The label above his head is a symbol of power and position. He is one of the main persons in charge of this project.

The other two persons in charge were female sulfur-based beings. They came from two other countries and also walked into the room at this time.

A researcher immediately replied: "Theoretically, it is possible. Although the surface of the cuboid is smooth, we can use containers to pack it, but the actual operation is extremely difficult.

According to the latest data, the mass of this cuboid is about eight tons. We have the ability to launch eight tons of objects from our planet into space, but we do not have the ability to send such a heavy object back from another planet! Of course I don’t need to explain the reasons. "

The person in charge nodded. He actually understood that if he wanted to transport it back, he must have a rocket construction base in Zhongxing, but how was this possible?

So he talked about another related matter: "According to the latest agreement reached by the three countries, we will establish an Alien Defense Council. The rotating chairman will change every three years. The council will be under the agreement drawn up by the three countries. Use your maximum power to promote the construction of a base in Zhongxing."

They have already decided on the location of the base, and it will be built on that rectangular parallelepiped.

Since it can't be transported back, then go there and do long-term research.

However, it is not that easy to build a base on an alien planet. According to the current technology of sulfur-based civilization, it will take at least fifty years.

At this time, they got the latest news about the cuboid.

The three astronauts first used an ordinary ruler to measure the cuboid. The short side was 3, the long side was 4, and the diagonal length was 5.

"It's an error. Didn't they replace it with more accurate measuring tools?"

A scientist looking at the screen said that due to communication delays, it would take about half an hour for the three astronauts to receive the instructions here.

The same thing they saw here, so he could only worry.

"The three astronauts are all elites of civilization and have received professional training. They have already been trained for these measurement and detection projects. Just wait and see!"

This was said by the person in charge. As soon as he finished speaking, the astronaut in the picture switched measurement tools. However, as the astronaut's measurement tools became more and more sophisticated, the room full of scientists became quieter and quieter.

"This is incredible! Is this alien technology? It's a miracle!" A voice broke the silence.

Then others marveled.

The equipment brought by the astronauts is already the most advanced and accurate equipment of the sulfur-based civilization, and the measuring equipment is also the highest precision of the sulfur-based civilization. But no matter how they measure, no matter how many times they repeat it, the accurate value they get is still the short side. 3, long side 4, diagonal 5, no error.

"There is no error! There is no error! Could it be a problem with our measuring tools? How could there be no error! Errors are bound to exist!"

"Old Yatou, accept the reality. Some things are inevitable for us, but for god-like aliens, they may not be inevitable."

"Haha. Yes." The sulfur-based life scientist known as Lao Yatou sighed. He slowly exhaled a mouthful of hydrogen sulfide gas and continued: "Absolutely smooth, no error! It's a miracle!"

Now, all the sulfur-based civilization scientists present understand that this alien civilization is using this method to arrogantly show its power.

Those present were all the scientific elites of the sulfur-based civilization, and they understood what this power meant to the entire sulfur-based civilization.

Like a god!

No wonder the detectors from the United Islands ten years ago did not respond no matter how they tried to communicate.

Now they understand that it is not that the other party does not respond, but that the sulfur-based civilization is not qualified for the other party to respond.

At this time, a loud roar suddenly appeared in the huge room: "This is impossible!"

Because the roar was so loud, most people in the room stopped whispering and turned their attention to the roarer. What exactly made him so excited.

You must know that everyone here is a group of people with very high scientific literacy. Even if they know that this is an alien civilization that looks like a god, there is no need to shout so loudly!

Oh, he turned out to be a mathematician!

At this time, everyone recognized the identity of the exclaimed person. He was a very famous mathematician named Genli.

At this time Genli continued to murmur: "How can the hypotenuse be 5? This is impossible! The aliens are wrong!"

He felt that the mathematics building collapsed all of a sudden. He said this, but in his heart there seemed to be another self whispering to himself, the alien civilization is yes, it is 5.

And when he said this, others also realized this.

Yes, how could it be 5?

The short side of a right triangle is 3 and the long side is 4, so the exact value of the hypotenuse should be 5.048517015727 and it should continue in an infinite loop. How can it be exactly equal to 5?

"Quick, get the most accurate caliper!" Genli shouted at this time,

"No, no need to take it, come with me!" The person in charge was obviously aware of the seriousness of the problem.

After he finished speaking, he took Genli and some scientists to another room, and then said: "This is this base, and it is also one of the most advanced laboratories in the entire civilization. There are all kinds of measurement tools, you can use them as you like!"

Needless to say, a group of sulfur-based civilization science leaders and mathematicians had already taken action. They used the stupidest method to set up two vertical laser transmitters, and then marked the two vertical lines formed by the intersection of the laser marks. These two points are 3 meters and 4 meters away from the two right-angle crossing lasers respectively, and then measure the length of the hypotenuse of the triangle they form.

They didn't just do one set of experiments.

But no matter how many sets they did, the hypotenuse they measured was equal to the theoretical value, which is 5.0485. In other words, it is not equal to 5.

This result puzzled all the scientists including Genli. Could it be that the measurements on this planet and Zhongxing are still different?

With this doubt, they asked the astronauts to use clumsy methods to make them on the spot or directly go back to the landing module to draw right triangles and squares, and then measure the hypotenuse or diagonal.

However, after months of hard work, no matter how they drew or measured. If you measure the hypotenuse of your own triangle or the diagonal of the square, the result will be slightly greater than 5, but as long as you measure the diagonal of the alien's cube, it will be exactly equal to 5.

What exactly is going on?

Obviously the textbook states that the approximate value is 5, but why is the exact value of this alien civilization object 5?

At this moment, the mathematicians of the sulfur-based civilization went crazy, and science could not explain this phenomenon.

Who was wrong? !

Suddenly, the entire sulfur-based civilization was involved in thinking about the Pythagorean Theorem.

Of course, most of them are used to brag after dinner. Most of them think that this is deliberately hyped by scientists in order to get more funding.

Some people promote this topic as an unsolved mystery. For example, there is a new one added to the top ten unsolved mysteries of the Purple Planet. It is this group of people who created it.
