The tree stick stood in the soil, and the shadow fell straight on the ground.

Bi Fang marked the location of the shadow in the soil, and his movements were gentle and detailed, just like a master repairing clock in an alley, using tweezers to clamp parts and assemble little by little.

If it weren't for the previous remarks, some people might really think that Bi Fang was doing some watch repairs.

[Measure the latitude and longitude, no, no, no one really expects a wooden stick to measure the latitude and longitude? 】

[A stick to measure latitude and longitude? Is Fang Shen joking? 】

[Lying at home, I quickly turned on the GPS and took a look. I was scared to death. Fortunately, it was not me who lost the connection ()]

[Can the latitude and longitude be measured directly? If it can be detected, our Fang Shijie will stand upside down and diarrhea on the spot, and then eat it! 】

[Don’t cheat, why don’t we show you a toothpick picking? 】

Not only new viewers do not believe it, but even many old fans are skeptical.

"Fake? How can the latitude and longitude be measured with a wooden stick? The current anchor deceives people also need to talk about the basics?" On the subway, a man dangled a ring and couldn't help but make a sound.

The subway was crowded with people. He stood here for a long time and stumbled upon the two little girls in front of him watching the live broadcast. He glanced curiously and saw this scene.

On the phone, a man who was a little more handsome and a little bit younger than him blew, then he stuck a wooden stick on the ground and drew two marks, saying that he would use this to measure the latitude and longitude.

There is no way to deceive people, how to break it?

Only a little girl who is out of society will believe it, she looks pretty, why don't she have no brains?

Yang Ziyan turned her head and glanced at a man who looked like an office worker was slandering her idol. Can this be tolerated? Immediately retorted: "How impossible, you can't do it doesn't mean that Fang Shen can't do it, he is the world's number one survival master!"

"Fangshen? Master Survival? No. 1 in the world? He laughed out of his teeth, not to mention the title of scumbag, who won the title of No. 1 in the world? Is there a competition?" The man dismissed it.

He pointed to Yang Ziyan and her classmates: "You little girls, you don’t know how to go to school, and you know you chasing celebrities and internet celebrities all day long. In fact, these celebrities have to die, and they are worthless. This is a little more handsome, but it’s the same. , It’s better to read two more books to enrich yourself."

Just as Yang Ziyan wanted to refute, the classmates on the side had already made a splash: "Uncle, have you never watched the news? So self-righteous? My grandfather can read the news online. No one can even read the news? No, no, no. Bar?"

The man who was pierced by a sentence of uncle took a mouthful of blood.

"Oh, I see, it must be because the uncle is under too much pressure to work overtime, the boss is very fierce, and there is no expectation of promotion, the wife **** with the daughter and has a puppy love, so there is no time to surf the Internet! Hey, it's so miserable. With him, bad temper will be contagious!"

The classmates spoke quickly, and then pulled Yang Ziyan to squeeze the crowd away, leaving only the dumbfounded office worker.

Yang Ziyan on the side gave a thumbs up silently.

But even if the two ran away, the man could still vaguely hear what they were talking about.

"It's really maddening me. When Fangshen fought against the wolves, this guy didn't know where he was constipated."

"Okay, okay, since he is so miserable, we also have to weigh it up." Yang Ziyan smirked, covering her mouth.

Wori.

This uncle can bear it, but my aunt can’t bear it either.

The man who was stabbed in the pain was angry and couldn't swallow this breath. He just saw the name of the live broadcast room!

The man took out his cell phone, downloaded a Langya app, and saw Bi Fang's live broadcast at the first glance.

He doesn't believe it, no one can see this deceptive routine?

No, he really got better today. If he doesn't tear him down, he won't get off the subway!

"The calculation of latitude and longitude is actually not difficult. It is just three factors: the shadow of the sun, the direction and the date. Don't feel unbelievable. I don't rely on a wooden stick here, but the sun."

Bi Fang pointed his finger at the sun hanging high in the sky. The weather was fine today. The sun rose above the clouds, and the sun was flat against the clouds, casting shadows of trees on the ground.

"From a phenomenological point of view, we can regard the ground as a plane and the sky as a sphere, which is called the "celestial sphere." The sun follows a circular trajectory on the celestial sphere, rising in the east and setting in the west. "

"Not just the sun, all the celestial bodies, the moon or the stars, are all on this celestial sphere, rising from the east to the west, as if rotating around an axis. This axis is the rotation axis of the earth."

"The position on the celestial sphere pointed to by this axis is the north and south celestial poles. We confirm our position on the plane of the earth based on the positioning of these celestial bodies."

Bi Fang explained the principle a little, and continued the actual operation, marking along the shadow just now.

"First of all, we must set up a pole on the level ground. Remember, we must be as level as possible, so that the measured data is accurate, and then continue to draw its shadow. When the shadow is the shortest, record the shadow at this time. Direction, this is the true north direction."

"After that, measure the length of the shadow and the pole at this time, use the trigonometric function to calculate the elevation angle of the sun, and then consider the date of the spring and autumn equinoxes and the summer and winter solstices. The day I set off is the 21st, so today is the 22nd. Use trigonometric interpolation to calculate the latitude of the direct sun on that day, and add it to get the local latitude."

"In addition, after obtaining the true north direction, record the time when the sun passes due south. Because the capital time uses the time of 120 degrees east longitude, the longitude can be obtained by using the recorded time and the time difference of 12 o'clock."

"However, this method is complicated in calculations and may not be suitable for everyone. Isn't there a saying that you can't do math problems? You can only write a solution."

[My grass, what is this stuff, why can't I understand? 】

[No political problems, you can write randomly, English composition can't, you can copy and read comprehension, mathematics big problems can't, you can only write a **** solution. 】

【Algebraist】

[Unexpectedly, I'm all in the wilderness, and still do the **** math problems? 】

Many viewers suddenly collapsed after hearing the series of explanations.

Bi Fang on the side began to observe the shadow of the sun. Fortunately, the shadow was shortening. The time was just approaching noon, and he did not miss the shortest point. If he missed it, then Bi Fang could only wait for the night to measure the latitude and longitude with the help of Polaris.

Ten minutes later, in the chat between Bi Fang and the audience, the shadow finally came to the shortest point and began to extend.

Bi Fang hurriedly put a mark, and started formulating formulas with branches on the soil beside him. At this moment, a few sheets of white paper and pencils were suddenly handed to him.

Bi Fang subconsciously took the pen and paper, and saw Etienne in front of him for a moment: "Where did you get this?"

Etienne scratched his head embarrassedly: "I brought the homework, and it was on the plane. Now there are a few draft papers left."

[Good guys, there is still homework? 】

[Niubi, I don’t forget to bring homework when I ran away, I’m a good student at first sight]

Bi Fang was also bewildered by the show operation, but with paper and pen, it was much more convenient. Then he sat on the rock and wrote a series of formulas that the water friends were not aware of with a pencil.

[It's over, if I don't know mathematics, would I still be unable to make a living? 】

[This formula is so big to me that Lao Fang actually calculates the function in hand! 】

[I have never been so serious in class. I'm so sorry to my math teacher. 】

"In fact, it doesn't matter if you don't. The real survival in the wilderness rarely uses this method to confirm the latitude and longitude, but this mission is more special."

"And it's really not possible. You can also wait for the night and use the Polaris to measure it. In the wilderness, the stars are very clear. This method is also simpler~www.readwn.com~ I will teach you when I have the opportunity in the evening."

Bi Fang was immersed in his calculations, and had to bite his pen from time to time. Many functions were not accurate without a calculator. They could only find an approximate value to substitute. The audience was dizzy during the process.

When Bi Fang calculated the answer, the paper went dark.

Strange, how dark it is.

Etienne looked up.

Lead-colored clouds pushed from the southeast, and the thick clouds gave people an ominous premonition.

Etienne suddenly remembered what Elwan had said, there will be a blizzard the day after tomorrow.

And now,

Blizzard is ahead of schedule!
