No matter how Yang Meng asked, he refused to answer what happened. Since she didn't say Yang Meng or asked, it was better if she didn't want to go back, the four of them had a lot of fun in the horse farm, and they didn't reluctantly go home until the evening when they urged them to go back for dinner.

"You've talked about it, and how did you decide in the end?" asked Long Xixiang.

Yang Meng said directly: "Come and beat it out directly! See me once, beat it once! I'll be responsible if I'm caught!"

"Can I go?" Dandan asked.

"When I beat your uncle, I'll let you go!" Yang Meng said.

Dandan's face was black: "Dad, can you let my uncle let me go?" I'm just a high school student, who can withstand his training method." ”

Long Xixiang said to Dandan: "Believe me, when your father practiced your uncle, you were just a pediatrician, and if you let your uncle practice you, you will protect you, if you let your father practice you, now you may have run away from home and don't recognize this father." ”

Dandan was puzzled and asked, "Dad, I really don't understand, why do I want to practice so strong? What kind of society is it now?

Yang Meng explained: "Let me tell you, a man must be strong at any time! ”

"I'm going to practice martial arts with my uncle and basketball with Uncle Michael, but I'm obviously going to follow the school of thought. Dandan protested.

As a result, Long Xixiang complained on the side: "I was speechless when I saw your so-called scientific research project recently, what 'how many times can a wet dog swing and shake the water to dry itself', 'more hair on bees or more hair on squirrels', 'how long does it take for a racehorse to urinate in a soak of urine', 'why yawning is contagious', 'who is the next supermodel', 'will cheerleaders look more beautiful after forming a cheerleading team than when they are alone'。。。。。。 What kind of research project is this?

After hearing this, Dandan said directly: "Mom, you are wrong, these projects are not my research, but the research topics of real scientists, and these projects are very meaningful, I am learning from these scientific research projects to stimulate my mind and way of thinking!"

Yang Meng nodded: "Well, it's right to do this." Daddy has your back!"

Long Xixiang's eyes widened: "What's right! What kind of mess is this? This is also a scientific research project?"

After hearing this, Yang Meng said: "Dandan, continue to study, your mother doesn't understand anything! Let me tell you the truth, if it weren't for the fact that I knew that you were studying these things, I would have directly taken you from your uncle's hands and trained you well! You are still too weak! It is not a problem for those uncles of yours to climb mountains and mountains at your age! As a result, your body is the capital of the revolution, and no matter what you do, you need to have a good body to lay a foundation." ”

Dandan said helplessly: "Yes, yes, I have been listening to these words since I was six years old and have been hearing them now." ”

After hearing this, Long Xixiang kicked Yang Meng directly under the table: "What do you say? What do you mean I don't understand? What is the point of looking at the things he studied?"

Yang Meng glanced at Dandan: "Did I explain it to your stupid mother or did you explain it to your stupid mother?"

Dandan blinked: "Dad,

Do you really understand?"

Yang Meng said disdainfully: "There are three projects from Georgia Tech in it, right? I remember reading this paper report, which was a paper by a professor named David. ”

Dandan hurriedly said, "Dad, don't say it, let me explain!"

Long Xixiang and the others, you look at me, I look at you, they are all confused, and finally Nakamura Miyu said: "Dandan, you should tell me, I would like to know how many times a dog has swayed and thrown the water to dry himself What can be studied." ”

Dandan stretched out his finger and said: "The frequency at which a dog shakes itself is four times a second, what is the gravitational acceleration at this time? 20G! And an excellent human pilot is responsible for 9 G's gravitational acceleration!"

"Wait a minute!" Long Xixiang said, "What does it mean that it bears such a high gravity." It only means that they can be very uncomfortable too. ”

"Uncle Hong Hao made a documentary of the video taken by my father walking the 'Road of Bones' in winter and broadcast it on TV! Dandan asked, "What does Dad do to dry his clothes every night?"

After hearing this, Long Xixiang said: "You still test us at this level? This is to reduce the loss of heat in the body, and the loss of calories in wet clothes is too much!"

Dandan nodded, "That's right, it's important for mammals to keep their bodies dry, and at this point, my dad and dogs are exactly the same!"

Yang Meng's face was black: "Why can't I control my urge to beat you up for the past two days?"

"It's science! It's a rigorous thing, I'm talking about mammals, and in this regard, you and the dog are exactly the same, and that's not just you, in fact all of us are the same, and I don't necessarily get beaten when I put you and the dog together, but I really get beaten when I put your mother and the dog together!" Dandan said.

After he finished speaking, everyone at the table burst into laughter. Their family has been eating so happily for so many years.

Yang Meng said: "Okay, don't compare me with the dog anymore! Hurry up and explain this problem to your stupid mother! Otherwise, I will really beat you!"

Dandan hurriedly said: "Okay, Mom, I continued, mammals are not humans, it is impossible to get rid of their bodies by means of roasting fires and the like, they rely on shaking their bodies to dry themselves, and the smaller these mammals are, the more difficult it is to shake off the water, for example, if the mice want to dry themselves, they have to shake their bodies thirty times in a second, which is the speed of a small electric motor! For example, the hair of the mouse is very fine, and with the surface tension of the water on the hair, he needs to have a stronger centrifugal force to get the water dry. ”

Long Xixiang was puzzled and asked, "What does this mean? What is the need for research on this project?"

Yang Meng said angrily: "I really can't help it! Dandan, let me explain to you stupid mother! Have you ever sat on a merry-go-round? Is it true that the centrifugal force of the moon is greater in the outer ring? The smaller the centrifugal force near the inner circle? In the same way, put this research theory in life, how can you use this principle in your washing machine to achieve the most effective energy consumption and achieve the best effect? What is the theory on which the washing machines are divided into different gears now? Isn't it the result of this research?"

"Can this also be connected?" said Miyu Nakamura

Dumbfounded.

Dandan nodded and said, "So science is amazing, even if I don't become a scientist, I have to study their way of thinking, which will be of great help to my life!"

Miyu Nakamura asked curiously, "What is the need for the research of the project of 'more bee hair or more squirrel hair'?"

DanDan explains, "In fact, bees have as much hair as squirrels. It's all about three million, and the more hairs you have, the easier it is to accumulate dust. Let's take bees as an example, we all know that bees work hard to collect pollen, but how does it collect pollen? It's its own hair, and when it gets pollen on its hair, how do they clean up the pollen from their hair?"

The doll on one side raised his hand and said, "I know this, they bounce the pollen out of their bodies with a few flicks of their legs." Our biology teacher took us to observe the bees raised by Uncle Ou. ”

Dandan nodded and said: "The hair of bees is actually very hard and elastic, as long as you brush the hair with your legs, the hair on their body will directly bounce the dust away, and this theory can be applied to many aspects, such as the pharmaceutical industry, the original gauze is smooth and flat on the outside, so it can't hold too much medicine, but what if you design a 'hairy' gauze? This can make more medicine in the gauze to help patients recover, you should know that there is a 'funny Nobel Prize' in the world, right?" Almost all of the winners are the kind of research that 'laughs at first glance and is sobering after research'. ”

One side crooked said: "I know this, there is another person who won the funny Nobel Prize because he found that all mammals urinate for 21 seconds." ”

Yang Meng said: "No, no, no, crooked, this is wrong, the accurate statement is: mammals weighing less than three kilograms peeing time is almost less than one second, and more than three kilograms of mammals urine time should be 21 seconds plus or minus 13 seconds, that is to say, 8 seconds to 34 seconds, elephant and a dog peeing time is actually about the same! This is because the urinary system of mammals is almost similar, that is, the bladder is connected to the ureter, and the length and diameter ratio of the ureter is almost 18 to one. So even if an elephant has a large bladder, it will urinate faster. ”

"What's the use of discovering this?" Long Xixiang said with wide eyes.

Dandan said: "Of course, it is combined with fluid mechanics for engineering, you have forgotten the crazy pool worker who poured water out of the pool while putting water into the pool in elementary school? ”

After hearing this, Miyu Nakamura sighed with emotion: "It seems that our family is going to produce a scientist!"

Dandan said, "I don't want to be a scientist, I just want to do what I want to do!" ”

Yang Meng snapped his fingers: "That's right, our children don't plan their future lives, just do what they want to do!

"Don't educate us on the spot," Dandan said, "Uncle Michael asked me to remind you not to forget to come over tomorrow." ”

Yang Meng was stunned: ", come again?"
