The situation is a little delicate, and I have to carefully search the 2014 edition of the experimental catalog of the first semester of junior high school physics. Pen ~ fun ~ pavilion www.biquge.info

When the book is used, I hate it less, and I really didn't notice that the junior high school little pot friend actually began to come into contact with such useful content.

1. pulling out a pushpin;

2. How to transport the wood upstairs;

3. Explore the characteristics of using fixed pulleys and movable pulleys;

4. Explore the inclined plane;

5. Re-exploration of pulleys - exploration of mechanical efficiency;

6. Explore what factors are related to the magnitude of kinetic energy;

7. Why do cards jump?

8. Explore what factors are related to the magnitude of elastic potential energy and gravitational potential energy;

9. Observe the transformation of kinetic energy and potential energy of the pendulum ball;

10. Study whether the function changes the internal energy of the object;

11. Demonstration of ignition explosion - internal energy is converted into mechanical energy;

Before Kuai Fei crossed, after reading a few novels, he proudly claimed that he had mastered the technology of making soap, glass, and explosives, and that he could travel through the ancient world in his hand. As a result, these braggart novels are all lies.

In retrospect, it seems that the moving pulley system was more useful in how to transport the timber upstairs or something. However, this knowledge point may have been mastered by the craftsmen of the Great Song Dynasty.

The content of the various junior high school physics experiments, when I think about it, is mostly to stimulate children's curiosity about natural science, but in fact, the junior high school physics department has never intended to let junior high school students really grasp anything of practical value.

The only exceptions are concave and convex lenses, small hole imaging, and ...... Kuai Fei himself also felt very surprised, the most useful is actually a pendulum!

The optical effect of concave and convex lenses and small hole imaging is very magical in the eyes of laymen, and it is also very suitable for fallen Taoist priests to pretend to be ghosts, of course, it is more suitable for guiding good Taoist priests who really pursue the mysteries of the world to study hard and explore seriously.

How fun it is to light a match with a convex lens or burn an ant to death, and this is what junior high school students love the most! (Elementary school students can actually play like this, but they only get this question in junior high school.) ）

Well, the real thing without a convex lens is yes, and that's not a big deal.

Dr. Wu is now a ghost, at least considered a ghost by the other party. There is an advantage when it comes to bragging.

"Take one side of the transparent crystal stone and grind it into ......" Kuai Fei felt a little short of words. I wonder how to describe such a strange thing as a convex lens in words.

"Ground into a circle, a foot and a half in diameter. The middle is thick, the thickness is more than three points, the edges are thin, and the thinness is only one point...... which is planned according to the super large convex lens. Anyway, it's bragging, and it's only when you brag about it that it's bigger. After all, burning ants seems very obscene, at least a rabbit has to be severely injured to have national strategic value, right?

Shenxiao Palace is so awesome, there must be such a big crystal stone.

But our Fei Ge guessed wrong, and Liu Daoyou immediately shook his head: "How can there be such a big crystal ore in the mortal world...... Archimedes used hundreds of mercury mirrors to reflect the sun's firepower. ”

I'll go! Fei Ge was embarrassed at the time.

Liu Daoyou, you know too much!

After thinking about it, Liu Daoyou is actually right. It was Dr. Wu who watched a number of costume dramas and a number of time-traveling novels by himself and watched stupidly.

Archimedes is such an ancient Greek, a peer of Qin Shi Huang.

At that time, people already knew how to use a number of mirrors, and the group artistic exercises were arranged into a satellite array of pot lids, which was used to focus on the sun and burn the sails of the navy. Presumably, it is probably the idea of using countless fragments to simulate the stitching of large concave mirrors. This thing obviously has no practical value, and it has no industrial value, only theoretical value.

It seems that this theoretical value has already been grasped by my Song scientists.

Think about it, Alexander killed in India and Afghanistan, hundreds of Roman legions were captured by the Han Dynasty and sent to Tuyuhun to Tuntian to herd horses, the monk Faxian went to the Red Sea, and countless Arab merchants came to the Tang Dynasty and the Great Song Dynasty. The Persian emperor also infiltrated Wu Zetian's court to work.

Archimedes' stuff, the ancients have long spread all over the world.

Ay! Why is this never shown in many spicy costume dramas...... Forget it, don't go to the question of the directors, screenwriters, and authors now.

Hurry up and change to another topic!

"Well, I'm flipping a page around, and it looks like you've already figured it out. I'll turn the page back...... Hmm, how do you feel about this...... Liu Daoyou, do you know the principle of the pendulum? ”

Liu Daoyou's face was solemn, obviously touching the G-spot: "I want to hear it in detail." ”

Kuai Fei thought about it, and he should be cautious in this subject. Ancient people liked to wear jade belt rings the most. Tie a silk silk to hang it on your body, and dangle it with the pace of walking all day long. They couldn't have failed to observe a little bit of the pendulum's pattern.

But the pendulum wall clock must have been a very late, very late European technology.

The Chinese sages in this field are undoubtedly another blind spot, such an important talent.

European missionaries brought the chiming bell to the Ming Dynasty, and the Chinese called it "bell" instead of "timer" or "timekeeping machine". Even the definition of "bell" has been inherited until later generations without modification. This is a classic tragedy.

This is obviously a key technology related to the national timing standard, and accurate timing is related to the accurate determination of longitude by human beings, which directly affects the development of the great navigation industry.

If this thing is named "The Machine of Time", it means that the academic community attaches great importance to the concept of timekeeping.

I named it a bell, and it's a musical instrument. Dare to love our Dameng Dynasty Zhu family in the world, everyone regards the Western clock as a musical instrument to listen to?

So......

In the name of the Book of Heaven, it is a good name for the clock technology, and it gives Shenxiao Palace and the Marshal of the Great Song Dynasty a correct guidance, and it should not be struck by lightning in this way.

It can not only fool the ancients, seek a benefit for my brother and Ah Lian, but also benefit the progress of the country and the nation.

Why not?

So, pretending to recite the content of the book, in fact, it was made up and said......

"First there is the unspeakable Celeron xenomorph creature who said: The world is the book. There was also a fairy tale book written by Hawking's Brief History of Time, which said: Pangu created the universe with a singularity explosion ......"

Fei Ge said this in the name of Wu Dalang, in fact, he was afraid of Archimedes, and he took precautions to guard against the fact that Shenxiao Palace had some information from other crossing criminals.

With such a wise ancient, they would not dare to fool around.

It must be justified and well-founded.

It is likely that the other traversers that Shenxiao Palace has contacted have already confessed a lot about Hawking and Planck.

It's just that we Feige don't understand what a brief history of time is all about...... (Actually, no one understands what Hawking is talking about, right, in fact, the authors of countless great science fiction books don't understand either, but they copied some jokes from Baidu and let the protagonist pretend to be forced, right?) ）

Therefore, Kuai Fei had to beware of his pretending to be a ghost and clashing with other traversers.

It just so happened that before Brother Saiyang, I don't know whether intentionally or unintentionally, he gave us such a wake-up call.

Saiyang said that Hawking was just telling a fairy tale, and Saiyan said that the world was actually a book.

This alien junior high school student said it so well! This just solves the problem that our Feige is currently facing with the risk of pretending to be forced and the need to be cautious in pretending.

We cautiously state that we are not ignorant of Huo's theory, but that we are actually pursuing the orthodox science fiction doctrine of the Saiyan sect. The Alien Bishop of Saiyan said that Hawking is a fairy tale, that is, a fairy tale, so we, as a certain decent disciple, will never casually peek at the crooked and evil stinky works.

In this way, it also explains why the great holder of the Book of Heaven only knows the name of the singularity explosion for the Hawking routine, but does not know the details of the entanglement.

Because it's an evil sect, my generation has rules that don't allow you to steal crooked ways.

(What about a good junior high school student saving the world?) It seems to be seriously out of line. Said okay to play with the system in the big song.,It turned out to be a sister paper called the system.,Isn't it)
