"Wait a minute, I'll take a look at this clairvoyant mirror first, oh no, it's a clairvoyant mirror!"

Chongzhen was not very interested in Tang Ruowang's changes in the hope of the circle, but he was very interested in this Wanli Mirror.

If you want to talk about the telescope, it's not the first time he's seen it, there was one in the palace before, it was the gadget of the first emperor Tianqi Emperor, since the death of the first emperor, it has been hanging in the palace, and Chongzhen rarely moves.

However, he also knew that this clairvoyant mirror was very magical, and a simple cylinder was placed on his eyes like this, and the situation could be seen clearly and meticulously two and a half miles away.

Since the things that John Tang offered today dare to be called the Ten Thousand Miles Mirror, it is naturally much better than the Thousand Miles Mirror.

The emperor aimed his eyes on the cylinder, looked at the heavy snow outside, and after looking at it for a long time, he didn't see the name, and asked John Tang: "What's the matter, I can't see it." ”

Tang Ruowang's face was bitter, and he flipped the Wanli Mirror one by one.

Chongzhen's cheeks twitched slightly.

You're damn it, it's too big!

I took it down!

Then look inside!

Okay!

Through the heavy snow, the scenery at the door can be seen clearly.

"It's much better than a clairvoyant!" Chongzhen took down the Wanli mirror and put it on the table, and praised Tang Ruowang for a while.

When Su Baiyi saw the 10,000 miles mirror, he suddenly understood.

Since it is able to observe the starry sky, it must be the Galilean telescope that has just been invented. This soup John is also a real thief, and what he gave to the ministers was just an ordinary telescope, commonly known as a clairvoyant; But he didn't take out his own private astronomical telescope.

This kid, his heart is punishable!

"Your Majesty, if it's a clear night, you can hold it and look at the moon, so that you can see very clearly that the moon is actually a round ball, and it is pitted and ugly!"

"Not bad!" Chongzhen looked at Tang Ruowang and bowed slightly.

John Tang took the opportunity to bow down again and said, "Please allow Your Majesty to demonstrate the changes in the moon's acanic circle." ”

"Good!" Chongzhen is in a rare good mood today, and he is also a little curious about unknown astronomical things, so he agreed with a wave of his sleeves.

Tang Ruowang lay on the ground and kowtowed a few times to thank him, and then ran out "suddenly", whispering to his subordinates, and the subordinates went back to get the experimental equipment.

After a while, all the presentation items were taken.

Quite simply, an oversized candle and then a white marble ball, about the size of a fist.

At this moment, the snow was falling heavily outside, and the sky was unclear or dark, so Tang Ruowang lit the candle with thick arms in the hall and placed it on the ground not far away, and then pressed a support stick on the stone ball, and held the stone ball high with a support stick.

"Your Majesty!" Tang Ruowang held the stone ball only one meter away from Chongzhen, and said: "The moon is actually just a relatively large stone ball, it does not shine by itself, the reason why we can see it bright is because the sun's rays shine on the stone ball, so it is bright." ”

explained in simple terms, and then dragged the stone ball in his hand and placed it in the middle of the candle and Chongzhen: "Your Majesty, suppose the candle is the sun, your eyes are the people on the earth, and the stone ball in my hand is the moon, then at this moment, the sun's rays are shining on the back of the moon, so from your position, the moon is not bright, right?" ”

Chongzhen nodded deeply: "Yes!" ”

"Well, Your Majesty is the earth, immobile for a long time, the stone ball in my hand is the moon, and it revolves around Your Majesty every other month, so every time I move, it is equivalent to a day's time." Speaking of this, Tang Ruowang's steps took a step, took a step around Chongzhen, and pointed to the stone ball in his hand and said, "Your Majesty looks again, what may you see?" ”

Chongzhen shook his head.

Tang Ruowang took another step and said, "What about this? ”

Chongzhen raised his eyebrows, his eyes suddenly showed brilliance, and he took a deep breath and looked at the stone ball in Tang Ruowang's hand.

From his point of view, the stone ball illuminated by the candle only shone with a very thin arc below, like the first moon in the western sky like a hook.

Then, with each step of Tang Ruowang, the part of the stone ball in his hand that was illuminated by the light of the candle slowly changed.

New Moon – Elder Crescent Moon – First Quarter Moon – Gibbous Moon – Full Moon – Gibbous Moon – Lower Quarter Moon – waning Moon – New Moon

A cycle that demonstrates the moon phases for a month.

There is no need to explain why, the emperor already understands it perfectly!

This is the power of experimental science.

Even Su Baiyi, who was watching from the sidelines, couldn't help but applaud John Tang in his heart.

In later generations, the geography teacher in the classroom demonstrated this method, but now, in the early seventeenth century, John Tang was able to understand the relationship between the sun and the earth so thoroughly.

In this case, it is not surprising that he was able to accurately calculate the lunar eclipse.

It was demonstrated in a big circle and explained several times.

Not only the emperor, but even the civil and military ministers in the room were absolutely reasonable.

The first assistant of the cabinet, Wen Tiren, should be the original, he first clapped his hands to express his admiration, and said with emotion: "Master Tang is worthy of being an astronomical talent, and the old man is convinced!" As he spoke, he couldn't help but glance at Su Baiyi.

Tang Ruowang's performance today is very good, except for being robbed by Su Baiyi for a while, there is no failure. Especially the link of the demonstration of the lack of Shuowang Yuan and the gift of the emperor's Wanli Mirror just now is even more flawless.

On the other hand, Su Baiyi seems to have been making trouble unreasonably, completely like a soil dog who doesn't understand anything.

Wen Tiren snorted coldly in his heart, and his eyes gestured to Tang Ruowang.

Tang Ruowang instantly understood, smiled and straightened up his eight-foot body, and his body was like an abyss, and said to Su Baiyi: "Mr. Su, I don't know if what I said just now is correct?" ”

"Not bad!" Even Su Baiyi couldn't help but clap his hands, and then sighed deeply and said: "There is no vanity under the fame, Mr. Tang really lives up to his reputation, and it is roughly correct, although there are still small flaws in your explanation, but you Westerners can have this insight, which is already very remarkable!" ”

This is a sincere compliment!

At the same time, Su Baiyi is also reviewing for the Han people in his heart.

Look, what are people in the West doing?

Galileo invented the telescope, Christopher Columbus discovered the New World, and Magellan went to sea with enthusiasm to verify the theory of the circle of the earth.

And now, a second-class scientist John Tang can even dumb a bunch of high-ranking officials of the Ming Dynasty.

Therefore, it is not without reason that the West has always been ahead of China in modern science.

"What did you say?"

After listening to Su Baiyi's evaluation of him, Tang Ruowang was reluctant.

What does it mean to be roughly correct?

What do you mean by having a small flaw?

What do you mean by being already remarkable?

John Tang believes that his explanation has been flawless, just like the smooth bodies of those prostitutes transported from their hometown by Taiwanese red-haired devils, without any flaws.

"I said you explained it very well!" Su Baiyi spread his hands.

"That's not right!" Tang Ruowang's face was cold: "You said that my explanation still has a small flaw, impossible, there will be no flaws!" ”

"It's just a little flaw, but it doesn't actually affect your interpretation of the changes in the circle of synodics." Su Baiyi smiled and kindly excused him.

"Where's the flaw?" Tang Ruowang gasped and took a big step forward with great momentum.

Su Baiyi frowned, looked at Tang Ruowang with a painful face, and thought for a while before saying: "Forget it, this thing is a bit profound, you can't accept it for a while, just when I say it's wrong, your explanation is perfect, okay." ”

"Master Su, are you joking with your boss?" John Tang was very angry.

"No, I'm just, to tell the truth!"

"You're vexatious!" Tang Ruowang decided that Su Baiyi couldn't understand his demonstration at all, but was making trouble for the sake of shame, so he had a hot brain for a while, and said something that made Su Baiyi excited: "Master Su, dare you bet with me, if you can tell me where the flaw in what I just said, I will give you 10,000 taels, silver!" ”

Hiss......

Su Baiyi gasped.

This foreign devil is so rich?

However, the family property of this dog day should be all deceived by the Chinese church.

Thinking of this, Su Baiyi decided that he must vent his anger for the people of Daming and let the foreign devils spit out the silver swallowed in his stomach.

10,000 taels is enough to buy a lot of materials, and it is more than enough to build two teaching buildings.

I know that Lao Tzu is short of silver, so you can send it to me, right?

Are you a tease sent by Lei Feng?

"Good!" Su Baiyi immediately agreed, and arched his hand to the surrounding courtiers, and said: "All the adults have heard clearly, and please give Su a witness, if I can point out the fallacy in what Lord Tang just said, Lord Tang will lose 10,000 taels of silver to the next one, if I can't point out Lord Tang's mistake, I, Su Baiyi, will lose 10,000 taels of silver to Lord Tang." ”

"No need!" Emperor Chongzhen waved his hand directly: "I will give you two a witness, believe me, no one dares to cheat!" ”

"Good!"

Tang Ruowang sneered and looked at Su Baiyi, arching his hand: "Please also ask Master Su for advice, I don't know if what Tang said just now is wrong?" ”

"Ahem, cough, ahem......" Su Baiyi smiled innocently and spread his hands towards Tang Ruowang: "I seem to have heard the adults just say that the earth is eternal and does not move, and all celestial bodies in the heavens and the earth revolve around the earth, isn't that so?" ”

"Yes!" John Tang replied in an extremely affirmative tone: "As long as it is a celestial body in this stellar sky, no matter the sun, moon and stars, they all revolve around our earth, is there a problem with this?" ”

"Of course there is a problem!" Su Baiyi smiled and said: "Ahem, as far as the old man knows, the truth is this, the moon revolves around the earth, and then the earth revolves around the sun with the moon, and the other planets in the solar system move around the sun like others." ”

"Fart!" As a Catholic, after hearing Su Baiyi's remarks, he became angry: "Nonsense, who told you that the earth revolves around the sun?" ”

Su Baiyi was stunned: Are you pregnant, and the reaction is so big? But then he smiled cheaply: "No one told me, I guess!" ”
