The hot air balloon debut, just like a magic show, is a sensation in the city! Let everyone sigh deeply that this trip is worth it, and even many people still linger, wanting to wait a little longer to see if there is a chance to go to heaven. Pen, fun, and www.biquge.info

This roadshow completely consolidated Liang Kai's position in the high-level of the mountain city, and by the way, cleared the difficult imps, and then it was simple......

First of all, the hot air balloon has to be made a full version, and it is a bit embarrassing to only hang one person.

The original plan was to carry two people, but the unusually large expansion rate of the air from the otherworldly heat caused another Kai to change the plan.

Three people are definitely better than two, even if it is still two people, it is good to be able to decorate more.

To this end, the diameter of the airbag is measured and the volume is calculated; Use a large scale to weigh the airbags, ropes, and human weights to calculate the buoyancy generated by the heating of the air, and calculate how much the airbag has to be enlarged to meet the new design requirements.

At the same time, some of the oil of all kinds in the warehouse was requisitioned.

A row of oil stoves is erected, the same iron pot is filled with the same amount of water, and then the fire is lit.

Someone watched each pot, when the water boiled, recorded the time, and then extinguished the fire to record the amount of oil left.

In this way, the oil is divided into categories, which oil produces the most heat by weight, and which oil has the most fire and boils the water the fastest......

The new hot air balloon can't use the oil stove of Nanhai Jing, so all aspects have to be considered.

At the same time as the oil was measured, the burner designed by the project team experts also placed an order with the smelter, of course, taking into account the processing capacity of the world.

Most people didn't know what Liang Kai was doing, so they didn't know what he was going to do, until the thing was almost done, and he had time to explain a little, and one by one he suddenly realized.

The truth is not complicated to put it bluntly, and the IQ online can basically be understood.

The difficulty is to simplify what is originally very complex and abstract......

It's like Newton's three laws of motion, the law of inertia, the law of acceleration, and the law of action and reaction, which seems very simple to put it bluntly. But before putting it bluntly, how many people can realize that the motion of objects follows such simple laws?

High mathematics is really complicated, even if it has been born for 300 years, it is still difficult for many people to understand; Those who can keep up with the progress of mathematics two hundred years ago can become a master's degree; You can be a doctor in a hundred years......

However, the things that can be touched in daily life are vague and vague in the hearts of the working people, and they lack sufficient logic to systematize and standardize.

The biggest difference between modern people and ancient people is that the logical way of thinking has been integrated into the flesh and bone marrow and even every cell of the body, and eating and drinking are as natural.

Of course, this is talking about science students......

The hot air balloon passed like this, and in the name of placing an order for the oil furnace, Liang Kai took the opportunity to visit the smelting workshop. It is not only to prepare for the improvement of the process and the promotion of the assembly line process, but also the precursor of the telescope.

What does this have to do with telescopes? There's not much technology involved in building a lens tube, right? Much lower than oil furnaces.

It's not the tube, it's the lens.

There is no glass in this world.

There is also no incentive to develop glass, because there is already an excellent alternative - resin.

It's a dark period, the sun is obscured by the giant Jupiter, and the whole world is plunged into darkness; And when the planet moves to the other side, you can imagine the sun hanging during the day and the huge Jupiter hanging at night!

Moreover, due to the huge area of Jupiter and its rings, the intensity of reflected light is almost the same as that of the Sun......

And there's nothing surprising about it.

In the case of the moon, for example, the brightness is 400,000 times worse than that of the sun.

It seems to be a lot, but it is only more than 600 times the diameter.

The 600 times the diameter of the moon is nearly 400,000 kilometers, slightly wider than the distance between the earth and the moon, and it occupies an angle of more than 80 degrees in the sky and less than 90 degrees.

Therefore, there are more than ten days of no sun in the polar night, and when it comes to the other half month, there are more than ten days of polar day, the temperature continues to rise, and the sun is 24x7......

Within a month, spring, summer, autumn and winter are alive!

With such drastic changes, animals can dive into the sky and dig burrows to adapt, and plants that can't move must have evolved strategies to cope, for example, secreting resin.

When exposed to extreme sunlight, plant trunks secrete mucus. The color becomes darker and darker in the sun, and when the polar night comes, it becomes lighter to almost complete transparency, allowing the sunlight to penetrate smoothly.

Not only that, but it should also have a mulch film effect, allowing the tree to absorb more sunlight energy. Of course, these are the botanists of the project team.

For the inhabitants of this world, resin is undoubtedly the best glass!

Scrape down from the tree, heat and melt and process it into a plate inlaid on the window, adjust the light to be warm in winter and cool in summer, and it is not like glass that will hurt people, and even, when processing, you can also print a flower and engrave a word or something to decorate the material......

Ten green and high-tech! provoked all netizens to praise it

It's just that this thing is improvised, and it's too much worse to use as a telescope!

The texture is soft and easy to scratch and deform, and the light transmittance is also seriously insufficient, hazy and hazy is more like ground glass, and people from other worlds who have never seen real glass can make do with it, and it is definitely a joke to use it as a telescope.

"In addition to the resin, the only material that barely meets the requirements is the star eye."

This is a shell-like material, with absolutely no problem with transparency, and it is born with concave and convex properties, which is the eyeshell of a very peculiar kind of magical beast.

It's a pity that this thing is like tempered glass and can't be processed. The shape can also be fine-tuned, and its shell-like structure is distributed according to the eyes of the monster, and the curvature can only be as much as it should be.

And all of them are different, regardless of radians or degrees or size...... If you want to come out with a telescope, it's just four words, resigned to fate!

"It seems that you can only go directly to the reflex type......" Liang Kai smacked his lips.

Reflecting telescopes consist of a parabolic concave mirror and a flat mirror, which does not require any light-transmitting material. Coupled with the magic mirror technique, it really shouldn't be difficult.

However, the surface accuracy of a reflective objective has a double effect on the optical pathlength, and if imaged by only one reflective surface, the surface requires four times more accuracy than a single refractive surface......

It is not easy to polish ordinary lenses, and whether it can meet the accuracy requirements Liang Kai, including the expert group, is not sure, and the difficulty is four times higher, which can be imagined......

[In this world, there are still advantages to reflective type. The most difficult thing about the reflective type is maintenance, the open lens barrel is easy to enter the dust, contaminating the mirror, and the reflective force is reduced. But there is a mirror-making technique, a matter of spells......]

[In addition, we don't want to look at the stars, we don't need such high precision and multiples.] To make a portable one, the requirements are not too high. It's a question of which to choose, Newton or Cassegrain? 】

[Cassegrain must be, Newton's view from the side is awkward after all, especially in a hot air balloon. 】

The expert advisory group discussed a lot, and all netizens, except for a few astronomy enthusiasts, were once again in a state of confusion.

It's good if some people don't know how to be strong, and some people have to be serious, and if they don't understand, they will check the information, and one by one Baidu hot words were born.

Although it has not been a long time to travel through the other world, the science popularization boom it has caused on a global scale has made netizens admire and yearn for science, and the effect is immeasurable.

As he spoke, Liang Kai walked into the workshop on the right side of the Star Tower, led by Yue Zhenzhen.

He took office as a new official, and Yue Zhenzhen, who temporarily took over the position of Red Blood Lie, also accompanied him to place an order to patrol the territory.

In the workshop, just as Liang Kai expected, the fire was blazing, the heat was radiating, and the sound of "clanging" was endless.

But there are many differences......

For example, there is coal in this world, but incineration produces a lot of toxic gases, which can kill people...... That's why it's usually wood.

The wood isn't hot enough, but that's okay. The smelting furnace has magic, just like the oil furnace of the South China Sea, three one-star magic apprentices stand around the furnace, meditating on the magic pattern engraved on the wall of the furnace.

Flames burst out of the furnace, frantically licking the walls above, smelting the ore inside.

But in a moment, with a shout, several people pulled the chains, the lid of the furnace was opened, and the red-hot molten iron poured out, rushing along the preset trench like magma.

That's the power of magic!

After this period of collecting information and reversing the deduction, the earth side basically confirmed the principle of magic.

Contrary to many people's assumptions, it is very likely that the source force is not generated by the void, but follows scientific principles and conforms to the laws of thermodynamics.

So, where does this power come from?
