In the previous chapter, there was an error in the description of the Mayan text, which has been revised. Pen, fun, pavilion www. biquge。 info

"Brother Gun, what is the first number of their hundreds. ”

"It's hard to understand, it must be four hundred, it shouldn't be called a hundred, it should be called four hundred, it should be written as a point, a shell below, and then a shell below. A sailor helped answer.

"Bingo, that's right. Fang Hong smiled: "There are many talents among the sailors." ”

"Why?"

"You think, how did the decimal hundred come about, ten times ten, so the hundred in the decimal system is twenty times twenty = four hundred, and the thousand is four hundred times twenty = eight thousand. The counting method is that a dot represents one in the decimal system, in the decimal system, from zero to nineteen, although it seems that the symbol is complicated, it can actually be completed in a box, and to the twenty digits, the second box is enabled, which is equal to ten, the third is equal to the hundred, and the fourth box is enabled by eight thousands, which is equal to the thousands. ”

Actually, it's a single digit, twenty digits, four hundred, eight thousand. This has something to do with the base system of modern computers, because the decimal system is the binary encoded decimal.

"The Mayans invented the decimal system for the purpose of astronomical deduction, and every decimal system was invented for a reason. ”

For example, the decimal and sexagesimal systems of time.

For example, the hexadecimal system of ancient weighing, 16 two scales of stars, each represents a star, they are: the Big Dipper, the South Dipper six stars, plus Fu, Lu, and Shou three stars. If the short catty is less than two, less than 1 tael is called "loss of blessing", less than 2 taels is called "hurt Lu", and less than 3 taels is called "folding life".

After eating, Fang Hong looked at the sky: "It's not yet twelve o'clock, let's pack up and set off, and strive to enter the highlands before nightfall." ”

The forest is right in front of you, but it's still a few hours away from the flat forest into the mountains.

"Boom!" an eagle crowed, and a sparrowhawk flew over.

"Brother Gun, what happened to Chaotian?"

Fang Hong saw the sparrowhawk and also remembered Chaotian who had been separated for half a year: "Chaotian stayed where it should be, and now it is an adult, and the scientific team is still studying them, and Chaotian lives near the scientific team." ”

"It stands to reason that this kind of contact should not be, but if scientists want to study animals, they must enter a large number of animal communities and not be excluded, so if you really develop tourism in the future, you should not harm the animals on the island, because they are not afraid of people now, and they are the result of many people's efforts. ”

That guy in Chaotian is also an aggressive, just like mahjong, otherwise it wouldn't fight with the friship bird, although it's only the smallest of the frigate birds, it's also against the big bird.

"The sparrowhawk really looks like a falcon, but it flies towards the sky with a more divine attitude. ”

After moving forward a short distance, Fang Hong directly stopped and stood in place.

"What's wrong with Brother Gun?"

Fang Hong approached a tree: "I found a snake, I thought about it for a while, and I think the possibility of attacking me is relatively low, so let's take a look." ”

A large tree with a hollow trunk with a black and brown snake in it, which could be seen from its triangular and disproportionate head, which was a poisonous snake.

"The jumping viper, half a meter long, preys on careful mammals, such as mice, likes to stay in fallen leaves or hollow tree trunks and wait for food to come to the door, does not let go after biting the prey, and keeps injecting venom, causing the decomposition and destruction of the blood vessels of the prey, and internal bleeding to death. ”

The viper in the trunk did not stand still.

"It was clear that it was waiting for a rat that was bouncing and approaching, not a huge human, and when it saw me, it was already alert, and if I approached it, it might attack. ”

"Didn't you say it could jump, and Brother Gun was going to die again?"

"Can it jump, can't I jump? Fang Hong approached, and the camera followed.

"One of the twelve King Kongs of Central America, of course, it is not dangerous compared to the dangerous animals on other dangerous continents, but for humans, the smaller the animal, the more deadly, because large animals can't handle humans, I mean guarded. ”

The more you encounter small animals, the harder it is to guard against them, especially this kind of thing.

The jumping viper suddenly leaned forward and opened its large mouth, which was almost 180 degrees open, revealing fangs that were a little shorter than ordinary vipers.

Fang Hong quickly jumped back, and when the jumping viper retracted, Fang Hong approached again: "Xiao Xiang still scares me, if I don't see that you are a protected animal...... Forget it, I still don't like snake meat. ”

"Brother Gun, come, eat it, I sponsored the oil and salt fee. ”

"If you are caught and imprisoned, you fly over and bring me food!" Fang Hong pointed out his middle finger.

It is a deep green forest, and the perennial sunlight makes the plants here very luxuriant.

Also, the plants do not need to compete for sunlight and do not grow so tall, and the trunks of the plants here are not so thick, on the contrary, they are thinner.

"The trees in these primeval forests are not as thick as we think, because they don't actually live for many years in the natural environment, they don't need to be cut down by humans, and they will be replaced naturally, such as wildfires, such as insects, which will make them burp. ”

The colder the place with less light, the more straight and tough the plants in the natural environment, the taller and bigger, and the hotter the place, the less the plants pursue.

Therefore, the cold not only makes humans resilient, but also plants.

In this mountain forest, the most common thing to see is bananas.

"I suspect it's not a forest but a banana plantation, so many banana trees. ”

It's not a patch, it's not the kind of garden where there are nothing but bananas, but there are a lot of bananas.

After advancing for more than an hour, Fang Hong walked through a small dirt slope and saw a scene that made him doubt his life.

A couple of people with unclear skin tones who were black or brown were cutting bananas, and it was a cart that cut bananas.

", what a banana plantation. ”

It turned out that for the past two hours, Fang Hong had been walking in a large manor, and Fang Hong thought it was a forest.

The water friends were jubilant, and it was time for the water friends to slap Fang Hong in the face, and everyone was happy.

"Brother Gun has been advancing in private territory for a long time, Brother Gun, you are really in the wild, exposed, haha. ”

Fang Hong: "I said why Honduras is so small and the largest rubber exporter in the world, more than Luzon. It turned out to be because their banana trees and forests were integrated. ”

Crops like bananas, if the land is not fertile, will certainly not bear good fruit.

If the yield is too large and too many bananas are grown intensively, the longer the time passes, the lower the yield.

But when mixed with the forest, it's easy to solve, and the natural environment will solve the nutrient problem.

The bananas here are not grown one by one with maximum efficiency, but are scattered in a haphazard manner: "I don't know if this is a feature of this large estate or Honduras." ”

In fact, it is impossible to be like this, most manor owners do not consider the protection of the natural environment, and it is a big deal to fertilize.

And it's full of birds, and bird droppings are the best fertilizer.

In the past, in the southeast of South America, a valley gathered nearly 100 meters of guano to be used as fertilizer for digging, and it took more than 100 years to hollow out.

However, just over 100 years later, many Chinese in South America have become large estate owners rather than workers.

Leaving the banana grove, the whole scenery has changed, dense, but does not block the sunlight of the forest appears in front of you, from the sky aerial photography, you can't see the ground at all.

However, from the ground, you can still see the delicate sunlight.

The primeval forest, magnificent, wind-blown forest waves.
