...

An off-road mountain bike is on its way to Camp Metcham.

The physicist Emily, staring at a tired dark eye, was a little sleepy. But the ambiguous eyes cast by the sisters constantly made her want to die.

She looked at the handsome oriental man sitting next to her angrily, and asked her to ask about physics? No, no, he really asked for knowledge of physics. And it took me a whole night to ask for advice. She had the opportunity to go to bed at more than five in the morning.

Don't get me wrong, it's literally asking for physics knowledge. He went from the principle of flame, the construction of plasma, to the aerodynamics, to the principle of rocket launch. From the structure of the atmosphere to the linear velocity of the Earth ’s rotation, how to break through the speed of the first universe, the Big Bang, the possibility of multiple universes, the rationality of the existence of dark matter ...

At first she thought he was a subtle Oriental and needed to pretend to look like a transitional atmosphere. Therefore, she also answered his questions one after another with great interest.

But I didn't expect it to be endless, endless. In the end, she was going crazy. Throughout the evening, I was discussing the study of physics. At that moment, she had never hated physics so much.

These are just fine.

When Emily faced her dark circles, joined her sisters, and drove to Camp Machem, those envious and jealous eyes really made her want to find a hole in the ground. She knows what they mean, look at your haggard look, even if you are unrestrained, you do n’t have to spend the night, wait.

She tried to explain that one night was really discussing physics, but no one believed at all.

"Emily, I have a serious question to ask." Wang Yan was so radiant, with his physique, let alone sleep all night. Even if you do n’t sleep for a week, you will still be full of energy.

"Come again ..." Emily groaned inwardly.

"Last night we discussed that hot air balloons rely on air buoyancy to counter gravity. So the question is coming, assuming that the air density does not decrease sharply due to altitude, will the hot air balloons lift off indefinitely and escape the gravity of the earth? Bondage? "Wang Yan asked curiously.

"Of course, as long as you keep enough buoyancy to resist gravity." After all, as an expert in physics, Emily can easily answer Wang Yan's seemingly childish question even if she is in a bad mood, "There is enough air density. , It can obtain continuous buoyancy and maintain the balance of internal and external pressure. And as the height is higher, the gravity is relatively weakened, and its rising speed will be accelerated. "

"What about the speed of the First Universe?" Wang Yan frowned slightly. "Isn't it necessary to accelerate to more than 7.9 kilometers per second to get rid of the gravity of the earth?"

Emily fainted, really wanted to strangle this handsome oriental guy, can't you flirt? You asked so carefully, really want to fly out of the earth? With an expression of irresistible expression on her face, she reluctantly replied: "That means that without providing more power, it must exceed the speed of the first universe to get rid of the gravity of the earth. In short, if you want to move by objects Inertia must leave the earth more than 7.9 kilometers per second. "

"Emily, do you mean that as long as there is a continuous source of power, I can ignore the speed of the first universe?" Wang Yan said seriously, holding his chin.

"I will explain the plan a little more clearly." Emily glared at Wang Yan angrily. "If I want to kick you out of the earth, the strength of that kick must make your initial speed exceed 7.9 kilometers per second, because in the follow-up I did not continuously kick you to apply force to you, you must roll out of the earth by inertia, if you can not reach that inertial speed, it will be pulled back by the mother of the earth. But if I can I keep kicking you one after another, even if the speed is slow, I can kick you into outer space, understand? "

"Understood, easy to understand." Wang Yan said with a chuckle, "Thank you, Emily, you have solved a problem that has plagued me for a long time."

"Emily." The rest of the people seemed to be discussing the issue, and they came around with some curiosity. The beauty manager asked, "Then as you mean, if I add more fuel to the plane, can I drive it all the way into space?"

"Snapped!"

Emily flicked her forehead with tears: "Andy, the wings of the plane must rely on air to maintain the lift, and the engine of the plane is also driven by air. The higher our atmosphere, the thinner the air, The plane will fall. "

She is also drunk, why don't everyone understand such superficial physics knowledge?

Another student asked curiously: "Emily, the rocket liftoff has nothing to do with the plane? Then why not let the rocket fly slowly and continue to fly into outer space?"

"Gosh!" Emily felt that she wasn't coming out for a mountain vacation, but was teaching the kindergarten. She patted her forehead and said helplessly, "Your theory is feasible, but to do that we need a huge rocket cabin to supply rocket fuel, and the larger the rocket, the greater the driving force required, and a viciousness will form. Paradox. In fact, even if you can design a rocket that breaks away from the earth according to your theory, its energy consumption is far higher than the existing rocket. Energy consumption is a major problem. Everyone knows why the rocket launch site is closer to the equator. ?"

"I know." Wang Yan raised his hand and said, "Because the earth's rotation is inertial, and the line speed is the fastest on the equator ... This can save more power."

"Yes, do you need your teacher to give you sugar?" Emily glanced at Wang Yan quietly. "In fact, if the transportation cost of raw materials is not counted, Mount Kilimanjaro where we are is the most suitable. No. First, it is very close to the equator, which means that its natural linear velocity is high. Second, it is very high, farther from the center of the earth than the rest of the equator, which means that the linear velocity almost reaches the highest point of the earth. Third, it naturally has At an altitude of six kilometers, you can save some travel in the atmosphere. Fourth, the atmosphere above the equator is relatively thin, which can reduce air resistance. "

After she finished speaking, she dulled her face with a blanket: "Dear curious babies, teacher Emily is going to sleep." She just covered her face, but suddenly opened the blanket again, and lost her eyes at Wang Yan. , "Oh, dear Yan. If you really want to learn Superman to fly out of the earth, you must pay attention to the pressure inside and outside the body, otherwise you will slam like a toad. Of course, wear more by the way. A piece of clothing, which is very cold. By the way, because the warm layer of the atmosphere absorbs a lot of ultraviolet rays, the temperature is very high there. Be careful to take off your clothes. "

After she finished speaking, she covered her face and went to sleep, no one ignored it. She was able to see that the handsome man in the East was either having a problem or writing a novel. Why was Emily so unlucky, she finally came across a handsome looking man. How could it be a brain problem?

"Got it, thank you Emily." Wang Yan said with a smile.

As soon as she slept, the rest of the girls pulled Wang Yan away.

"Yan, are you too bad? It's too ignorant to embarrass Emily so exhausted."

"Come on, we have to climb the mountain in these two days."

"Otherwise, we can work on research projects together tonight. I don't know physics, but I know literature."

"This ..." Wang Yan dropped a cold sweat.

...

One day later.

Located in the headquarters of Italy.

Yan Zun wore a mask and sat in the command center. He used huge mental power to process information from all aspects at the same time and was given instructions.

Suddenly.

A handsome old man wearing sunglasses and an Italian handmade suit came in. He patted Yan Zun's shoulder and smiled with a sympathetic voice: "Why, haven't you caught your apprentice yet? It's okay, we don't Anxious, take your time. Haha, I like Comrade Xiaowang more and more, which will make you so emaciated. "

"Xiao Feifei, anyway, you are also one of the most powerful men in the world." Yan Zun glanced angrily in the past, "You are worried about your identity, can you come out wearing this one?"

"Today on Sunday, I just came back after the service. Would n’t it be possible to rest and rest?" Pope Guang took a chair and took off his sunglasses. He looked straight, and said, "Seriously, sit here and watch you eat. , Is the most comfortable and happiest thing in my life. This has given me a new interpretation and understanding of the words 'gloom and misfortune'. Today's weather is really good and worth a drink. "

"Snapped!"

Pope Guangming snapped his fingers, took a glass of fine wine, and took a sip. Clearly, it is a pair who does not go to work today and runs over to see a good show.

"Oh, do you think the stink boy can escape my palm?" Yan Zun smiled confidently, "I don't believe it, he can escape my big search line."

"Is the plane going back and forth checked?" The light pope pretended to be concerned.

"This time, I have assembled all the forces that can be mobilized. Even if he dares to get on the plane easily, he will be arrested as soon as possible." Yan Zun said indifferently, "I have also deployed all the waterways closely. Yes Well, last time he escaped using the deep sea. For this, I have called a few deep sea demon clan from the demon, they are not only very powerful underwater, but also communicate with the sea creatures. "

"Papapap!" The Pope Guangming applauded and said, "You really have enough blood to capture Comrade Xiaowang. It's a pity, why haven't you caught him yet?"

"I will catch him."

"Why haven't you caught him yet?"

"You ..." Yan Zun was so angry that his old blood almost spit out. Suddenly, his eyes lighted up, "Little Feifei, you said that the kid would go the opposite way, through the Sahara desert, through the entire Africa, and then Bypassing the Antarctic ... Yes, yes, I have little defense in that direction ... "
