Marin laughed for a long time before stopping, after all, it wasn't too cool to accept the real great god Da Vinci as a disciple. However, in the days that followed, Marin also tasted side effects - he was almost annoyed by Leonardo da Vinci......

Leonardo da Vinci was a very studious god and a great obsession with science. After opening the physics book of the second year of junior high school, I fell into it. Then, when I encountered a problem that I couldn't figure out, I came to trouble Marin......

"Teacher, how did you get the conclusion that the speed of this sound is 340 meters per second?"

Marin rolled his eyes when he heard this - paralysis, how do I know how to get it? I'm a liberal arts student......

However, he knows that this question can be verified. So he said to Leonardo da Vinci:

"That's what my teacher told me, and I don't know how to get it. However, we can verify this conclusion......"

Then, Leonardo da Vinci took a few people to an open place outside the city......

Leonardo da Vinci first had a 340-meter distance measured with a tape measure, and then placed a bell at the starting point. And he himself, with a stopwatch, went to the finish line......

"Let's go!" Leonardo da Vinci waved his flag at the point.

And after receiving the signal, the assistant at the starting point struck the bell with a mallet......

The moment he saw his assistant's gavel go down, Leonardo da Vinci began to say silently:

"One...... Two ......" exactly one second, and then, he heard the bell from the opposite side......

"That's true!" Leonardo da Vinci's eyes lit up with excitement. Then, excitedly, return to the palace to report the good news to Marin.

"What's so nice about that? That's how it is. In short, the knowledge in this book has been verified, and there is nothing wrong with it! ”

Then, Leonardo da Vinci continued to study on his own, and when he encountered something he didn't understand, he would bother Marin again......

Where does Marin have the patience to explain? Moreover, when he first studied, he didn't study it in depth, and the knowledge was just rote memorization.

In order to fool Leonardo da Vinci, he had to say - you go and go to the experiment to verify it......

Then, Leonardo da Vinci went out of his way to the sea level and verified that the boiling point of water was 100 degrees Celsius, and also verified that the boiling point of alcohol was 78.2 degrees Celsius. Then, the saltpeter ice method was used to verify that the melting and freezing points of water are 0 degrees. But when it came time to verify the melting point of the metal, I ran into trouble - there were not such a large range of thermometers......

In the end, Leonardo da Vinci only verified the temperature of tin and lead. Because, the melting points of tin and lead are both below the boiling point of mercury. No matter how high it is, the mercury thermometer will not be able to measure it......

"Teacher, how do you know that the melting point of copper is 1083.4 degrees? And how do you know that the melting point of iron is 1538 degrees? We don't have that much range thermometer! ”

Marin was annoyed by the question:

"How do I know? This is what your ancestor Albert Einstein told me, and I haven't verified it. Because, I don't have a large range thermometer! Otherwise, you can go to the blacksmith shop and try it yourself, anyway, the melting point of iron is four or five hundred degrees higher than that of copper. ”

Leonardo da Vinci really tried it, and sure enough, the copper melted first, and then the temperature rose by hundreds of degrees before the iron melted......

Then, Leonardo da Vinci was full of admiration:

"Master Ancestor, his old man is really powerful, and he is really a model for my generation! Speaking of teachers, when will we meet the old man? Students have a stomach full of questions to ask! ”

Marin sneered in his heart - if you can see Einstein, there will be ghosts, and people will have to wait hundreds of years to be born......

However, this is not the case:

"Your ancestor is determined to travel all over the world, and I don't know when his old man will come again......"

"Hey, I really hope to see the master soon......" The implication is that he dislikes Ma Lin, a teacher, who is not level. I can't explain a lot of knowledge points, what a rubbing teacher...... It's better to count on the powerful master to help answer it, at least it's more reliable than the teacher......

……

Marin then removed a magnifying glass from the telescope and asked Leonardo da Vinci to crouch outside the door and point it at a pile of dead leaves......

Leonardo da Vinci's actions attracted the bear child Caesar. Then, after waiting for a while, the old and the young finally saw the magnifying glass with the help of the sun, and set the dead leaves on fire......

"yes, it's really lit!" Leonardo da Vinci jumped up excitedly. And little Caesar also danced along.

"Grandpa, what are you playing? It's fun! Caesar asked in a milky voice.

At this time, Marin happened to walk to the side. So, he said casually:

"Caesar, don't call him grandpa in the future, just call him senior brother. Because, he's a student of his father! ”

Leonardo da Vinci was stunned, but he had to admit that there was nothing wrong with what Marin said......

And Caesar, who was only a few years old, really said in a milky voice:

"Hello big brother!"

Watching Leonardo da Vinci frown at Caesar, he really looks like a big brother and grandson monkey......

"Wait...... If my son is second in line, won't he become Zhu Bajie? No, I have to take another disciple as the second junior brother, and not let Caesar be the second junior brother......" Marin slapped his head suddenly, leaving Leonardo da Vinci and Caesar inexplicable.

……

Two days later, Leonardo da Vinci came again:

"Teacher, what does this 'gravitational' mean? How did it come about? ”

Marin was a little irritable, but suddenly an idea came to mind, so he said with a smile:

"You really want to know how gravity comes about?"

Leonardo da Vinci nodded violently, and then he was pulled under an apple tree by Marin......

It was the beginning of September, and the apple trees were full of apples and were almost ripe.

Marin smiled and beckoned Leonardo da Vinci to the apple tree, and explained:

"There was a great god named Newton who was sitting under an apple tree one day and thinking about something. Come, sit here and imitate Newton......"

Then Leonardo da Vinci honestly sat down under the apple tree......

After seeing Leonardo da Vinci sit down, Marin shook the apple tree violently, and then ran away......

Then, two apples fell, hitting Leonardo da Vinci on the head......

Luckily, Leonardo da Vinci usually liked to wear a hat. Otherwise, it will definitely be a big hit. But even with a hat, Leonardo da Vinci was smashed to the end. After all, he wore a fur hat, not a steel helmet.

"Teacher...... You ......" Leonardo da Vinci looked annoyed.

Marin grinned and said:

"Don't be angry, the god Newton was hit in the head by an accidentally falling apple, and then he thought of gravity."

Then, Leonardo da Vinci was immersed in the physics explanation of Da Ma Linyu, and forgot about being smashed in the head by an apple......

Later, Marin performed archery for Leonardo da Vinci, asked him to pay attention to the process of the arrow falling in the second half of the archery, brainstormed a complex problem for Leonardo da Vinci to combine inertia and gravity, and also mentioned the resistance of air......

The admiration on the face of the curious baby Leonardo da Vinci was, of course, not admiration for Marin's erudition, but admiration for the unborn gods such as Albert Einstein and Newton, who discovered these laws......

In the days that followed, in addition to dealing with government and military affairs, Marin was bombarded by Leonardo da Vinci's curious baby's "100,000 whys". Marin almost went berserk, but, considering that he would need Leonardo da Vinci to help him teach students physical chemistry in the future, Marin had to silently endure the toss of the curious baby Leonardo da Vinci......

And the only thing that makes Marin happy is that Da Vinci's learning speed is really amazing. A physics book in the second year of junior high school, the average child needs to study for one semester, but it only took Leonardo da Vinci two weeks to fully master it. Moreover, it is not difficult for him to give him all kinds of exercises......
