After Chen Yi prepared everything, he found the Tianzhu scientist again.
Then naturally, he was put into the confinement box again. The strong light was turned on, and Chen Yi was in a baking state again. After a while, Chen Yi seemed to be too hot. He turned his back to the strong light and lay in the corner.
After a while, the surveillance camera flashed.
But nothing seems to be wrong, keep working.
Three seconds passed, ten seconds passed, twenty seconds...
Chen Yi kept this action, motionless.
Some alert viewers realized something was wrong
"Have you noticed that this is exactly the same as the painting painted by Chen Yi?"
"Damn it, have you used that painting to block the surveillance camera?"
"Awesome, I clearly knew what he was going to do but didn’t realize it. I thought he hadn’t started yet, and now he’s still"663" lying in the corner."
"The technique was so fast, I didn’t even see it clearly"
"The angle of his design is very good, so that the surveillance camera can see most of his body, but his right hand cannot be seen. The right hand can be operated, and everyone has seen how fast his hands are, and it is difficult to detect with the naked eye. In an instant, you can use photos to block the surveillance camera. Even if you stare at it, you will only see a flash."
"Before, I only thought he painted like one, but now I realize how awesome his painting is. He obviously couldn't see the light and shadow behind himself, but he perfectly imagined how he looked lying there."
"Like the eyes of God, able to see beyond oneself"
"Others draw based on reality. He finishes the painting first and then reproduces the picture with actual actions."
Obviously Chen Yi had revealed this step before, but everyone was still shocked when they saw it with their own eyes. Only after seeing it with their own eyes did they know how awesome Chen Yi's operation was.
However, the surveillance screen was blocked, so it was unclear what Chen Yi was doing later. I can't see it anymore.
The director can only use words to tell everyone what Chen Yi is doing:"Chen Yi took out a homemade convex lens and used the convex lens focusing principle to gather the light from the strong light and bake the steel nails, just like using a magnifying glass when he was a child. Just like roasting ants, the steel nails began to expand and fall off when being baked. After Chen Yi baked the four steel nails, he broke open the steel plate and drilled through the steel plate."
"Below the steel plate was the internal structure of the ship. As expected, it went straight up and down. He climbed straight up and reached the top. He quietly opened a skylight door and finally confirmed the outside environment. It was the deck of a ship, surrounded by the sea. Just like one of the situations he guessed, the prison was on the ship."
"There were very few guards on the deck, and they obviously did not consider that the prisoners could reach here, and even if they got here, they would not be able to escape. The only way to die would be to jump into the sea. This led to them neglecting to control the deck. There were only two lookouts above the bow. The officer is observing the surroundings"
"Chen Yi didn't go out. He opened an opening under the skylight and could see the sky. He took out his sextant and started measuring. He quickly found out that the dimension of his location was 30 degrees and 22 minutes, which is the windless zone of the Tropic of Tropic. Then he passed the flushing The direction of water flow in the toilet, the water flow above the equator is counter-clockwise, so it can be determined to be the Tropic of Cancer. Then infer the longitude based on the time of day, climate, and geographical environment."
"Imagine you want to build a secret prison. You put it on the sea and choose 30 degrees north latitude. Because you want to avoid strong winds and waves. You would not choose the Caribbean Sea, the Pacific Ocean, or the east side of the China Sea. There is only one place that is most suitable, and that is Coast of Morocco. This is the high seas, the wind is calm, it is very close to the land, and it is convenient for supplies. It is the most suitable place to build a secret prison."
The audience in the live broadcast room couldn't hear what they heard.
Many viewers took out world maps for comparison.
"Let me go, can you determine so many things based on a simple sextant, time, flushing toilets, etc.?"
"Awesome, this is how knowledge changes your destiny"
"Without some knowledge these days, you can’t even escape from prison."
"I said that it is impossible to measure precise longitude and latitude with just a sextant. It turns out that so much other geographical knowledge is needed. I have not learned geography well, so I was confused."
"For the first time, I discovered that geography is so useful"
"I suddenly remembered that I seemed to have learned similar knowledge in high school, such as the northern and southern hemispheres, latitude and longitude, seven continents and four oceans... I never thought that this knowledge could be used in this way."
"I also remembered something, and I roughly understood the principle of the sextant. I will immediately build a sextant myself to see if I can measure the longitude and latitude of 0 here..."
"In fact, the measurement method is not difficult. The sextant has a fan-shaped shape and its components include a small telescope, a semi-transparent and semi-reflective fixed plane mirror, which is the horizon mirror, and a movable reflector connected with the index, which is the index mirror. The scale arc of a sextant is 1/6 of the circumference. When used, the observer holds the sextant and rotates the index mirror to make the celestial objects appearing simultaneously in the field of view coincide with the sea level. According to the rotation angle of the index mirror, the altitude angle of the celestial body can be read, and the error is about 0.2~1"
"Then consult the astronomical almanac to learn the equatorial coordinates of the celestial body on that day. Just plug in the formula: cosz sin sin + cos cos cost to get the latitude of the place. In the formula, z is the zenith distance of the celestial body (90 degrees minus the horizon height), is the declination of the celestial body, and t is the hour angle, which can be obtained by subtracting the local sidereal time and the celestial right ascension. The sidereal time can also be obtained by simple calculation.. If the geographical latitude is calculated from the sun's position, a simpler algorithm is: z+"
"It feels so interesting. I will test it later."
"Don’t check your own longitude and latitude first. After measuring, compare them to see if they are accurate."
"I'm so impressed that you actually find it interesting, my head is about to explode."
"Damn it, I actually studied geography on a variety show"
"Chen Yi has finished promoting mathematics, physics and chemistry, and has begun to promote geography 0.7."
Some viewers who didn't know much about it discussed it with friends who knew better. Some children asked about the geography teacher in the group, and some students even asked the geography teacher directly for consultation... The whole Internet has stirred up learning. The trend of geography.
After the geography teachers learned the truth, everyone was numb. I taught you well and refused to learn. Now you are learning geography from the prison escape case? But after reading it, they thought this was a good thing and could stimulate children's interest. Compared with Preaching is much better. Chen Yi’s set of measurement methods contains a variety of geographical knowledge. Once the children understand this set of methods, a foundation of geographical knowledge will be laid.
Although it is a good thing, I still feel sad. The children will one day I never expected to find my interest in learning geography from the prison escape case.
