In this age of scarcity of entertainment, gambling is everyone's favorite form of entertainment.

Up to the princes and princes down to the peddlers and pawns, no one loves to bet a few dice, the operation is simple regardless of the environment, and you can squat on the side of the road.

Therefore, the Qin and Han dynasties were the most prevalent period of gambling in the entire Chinese civilization, but because of the emergence of Chen Xu, the entertainment methods of the aristocratic class and the wealthy class of the Great Qin began to change greatly, and playing mahjong and chess has begun to become popular on a large scale, and the hobby of the scholars is still to drink wine and chat with their sisters in the Quyuan Miscellaneous House, but there are more pursuits to read newspapers, watch plays and write books.

"What Ben Hou is talking about is not only a bet, but also a very peculiar scientific and physical phenomenon, two iron balls of different sizes fall from a high place, which one do you think will land first......"

"Naturally, it's the heavy one!" Before Chen Xu's words fell, most of the people in the conference room stood up and shouted, but those who didn't stand up just hadn't heard clearly.

"Are you sure?"

"It's natural to be sure, whether it's a stone or an iron ball, the heavier it is, the faster it will fall." Zhang Cang couldn't help but speak.

"Hehe, okay, Ben Hou will make a bet with you, Ben Hou bet that the two iron balls will land at the same time......"

"Impossible!" This time almost everyone jumped.

"It's impossible to know at once, everyone is sure that the heavy one will land first, and Ben Hou thinks that it will land at the same time, so we will bet on it......"

"Master Hou, how about losing?" A craftsman said aloud.

"If you lose the bet of 100 yuan for each of Ben Hou and everyone here, but if Ben Hou wins, you will all strip naked today and stand on the street together with only dirty pants, singing, dancing and dancing for a thousand years, how about it?"

"It's not fair!" Someone shouted.

"Hehe, it's fair and fair, if you win, it's a hundred dollars, and if you lose, you can take off your clothes and dance!" Someone retorted.

"Not bad, not to mention how can I lose, Master Hou is here to send me money!"

"Let's go, you can go out and verify it now, and go find the iron ball......"

Nearly 200 people rushed to the courtyard outside the Academy of Sciences together, chatting and laughing, and many of them couldn't wait to pick up the stones on the ground and began to verify Chen Xu's statement.

But some people immediately feel a little apprehensive when they start experimenting, because whether they are held flat on their chest or high above their heads, as long as they let go of the two stones, they almost always hit the ground at the same time, and the difference in time is almost indistinguishable, even if someone stands on the steps or even a chair to increase the height, the result of this experiment is still the same.

Soon a sound of surprise came out of the crowd, and then the whole courtyard began to throw stones with both hands, and some other helpers and clerks who did not attend the lecture gathered around to watch this group of mentally handicapped Academy of Sciences elites throw stones with their hands above their heads in the courtyard, throwing stones over and over again.

"The ball is coming, the ball is coming!"

More than ten minutes passed, and a craftsman sweated profusely and ran out with two blue-gold metal balls, one the size of a lead ball and the other the size of an egg.

"Master Hou, there are no iron balls, can there be two copper balls?"

"Copper balls are fine!" Chen Xu took the two balls and shook them with his hands, the big ones were at least more than ten catties, and the small ones were estimated to be more than one catty.

"Master Hou, we have all tried it just now, and the time difference is not felt, if you want to verify it clearly, you have to find a very high place!" At this time, even Zhang Cang was a little unsure of the theory he had started, and his expression was both strange and apprehensive.

"High, naturally the higher the better, come on, climb to the eaves of the Academy of Sciences!" Chen Xu said with a smile.

Soon a wooden ladder was brought in, and a craftsman eagerly climbed up with a copper ball, and then carefully stood on the eaves.

At this time, three or four hundred people had gathered in the courtyard, and even the newspaper next door had many curious people running over to watch, and the courtyard was dark and oppressive, and all of them spread out in a circle and looked up in front of the eaves.

The craftsman stood on the roof of the house, and his height was about three feet above the ground, which was already the highest place that could be found at the moment.

"Attention, everyone, so-and-so let go!" With a serious face, the craftsman stretched out the two copper balls into the air, and then let go of his hand.

"Puff~" The two copper balls smashed heavily on the ground almost in order, and two pits were smashed out of the hard dirt floor every day.

"Wow~" Although the speed at which the two copper balls landed was very fast, almost everyone saw the result, that is, it was really as Chen Xu said, the two balls with huge differences in light and weight really landed at the same time.

"How so? Impossible, isn't this scientific? Many people's confidence began to waver at this point, and then they muttered to themselves as they looked at the two copper balls that smashed the ground out of the pit.

"It must be caused by the difference in the time to let go, give it a try!"

A craftsman picked up two copper balls and climbed onto the roof himself, but after a while, everyone still saw two copper balls that landed at the same time, and more people's confidence began to crumble.

"I'll test it!" Zhang Cang couldn't help it, climbed onto the roof with two copper balls, like two experimenters, and threw the two copper balls down at the same time, but the ending still did not change in the slightest.

"Master Hou, the eaves of this house are too low, and the copper ball is too heavy, so that it is impossible to distinguish carefully!" Some people still don't believe in this result.

"Xianyang City is ten zhang high, and the city tower is fifteen zhang high, if you still don't believe it, then how about going to the city tower with me for testing?" Chen Xu said with a smile.

"Okay~, the city tower is high enough, you can definitely see which one lands first!"

So in the midst of the noise and shouting, the Academy of Sciences poured out, dozens of carriages were not enough, and borrowed seven or eight carriages used by the newspaper circulation department to transport newspapers, and then rode horses, rode in cars, and nearly 400 people rushed out of the Academy of Sciences and went straight to the east gate of the city.

"Big news, big news...... A young man with a badge from the distribution department of Daqin Metropolis Daily panted and rushed into the new office of Daqin Metropolis Daily, broke into the editorial office and shouted.

"Hey, Steward Ma, you don't stay in the circulation department to sell newspapers, what are you doing in our editorial department? Where's the big news? An editor stood up and said hello.

"Hurry up, go to the east gate of the city, Hou Ye and hundreds of people from the Academy of Sciences bet to run naked......"

"What?"

"Holy!"

"Hurry up, go quickly, you will know the details when you go, and you won't see it if you go late!" The steward was sweating profusely.

"Let's go, let's go!"

Dozens of editors-in-charge and editors-in-chief of the editorial department threw down their work and ran out together, the huge movement attracted the attention of other departments, and some people also ran out to ask, and then a large group of hundreds of people eagerly urged the cart to ride horses to run outside the newspaper office, and when Chen Ping heard the news, almost half of the people in the newspaper ran away.

Outside the east gate of the city is very lively, many people like to run to the construction site of the Weihe Bridge on weekdays to watch the process of repairing the bridge, but suddenly hundreds of people came on horseback and car, most of them hung the badges of the Academy of Sciences and the factory, and there were also people who came galloping on horseback and car, including reporters and editors who hung the tag of the newspaper hall, and then inquired with each other for a while, the news spread faster, less than half an hour, there were tens of thousands of people around the east gate of the city.

The hundred generals and soldiers stationed at the city gate were frightened at first, and they drew their swords as if they were facing a great enemy, but after seeing the Qinghe Hou, they all breathed a sigh of relief and lined up to greet them, and after listening to the request of the Qinghe Hou, the hundred generals naturally agreed to come down, but they just climbed to the city tower and threw two balls, which was not a problem, even if the Qinghe Hou wanted to lose two people, it was no problem.

So under the arrangement of the hundred generals, there are soldiers who lead a few craftsmen to go up to the city tower with copper balls, because the city wall is slightly tilted, so the hundred generals also specially arrange people to bring a cloud ladder to build on the top of the city tower, so that a few soldiers use ropes to tie the craftsman firmly on the cloud ladder to the distance of nearly a zhang outside the city tower.

The city tower is fifteen zhang above the ground, that is, close to thirty-five meters, which is high enough, and it is also the tallest building that can be found in the entire Xianyang at present.

Outside the east city gate, the people below and the densely surrounded water were impassable, everyone looked up at the craftsmen hanging in the air, and in the distance, there were people running over.

The craftsman who was tied to a height of fifteen zhang was already a little unable to hold his urine at this time, it was too high, but under the stimulation of this unprecedented scientific experiment, the craftsman still slowly stretched out the two copper balls to both sides and shouted: "Pay attention and watch, someone has let go!" ”

The shouts dispersed with the wind, and the two copper balls also fell from the cloud ladder almost at the same time, and under the gaze of tens of thousands of spectators, two copper balls, one large and one small, whistled and fell under the clear sky.

"Puff~~"

In front of everyone's eyes, the two copper balls still smashed heavily on the ground at the same time as if they had been agreed, smashing into the soft soil and almost invisible.

Half an hour later, enthusiastic cheers rang out outside the east gate of the city.

Because more than 200 officials and craftsmen of the Academy of Sciences began to undress, and then they saw that a group of gentlemen, old and young, had all stripped off to a pair of obscene trousers, and some of them did not wear underwear at all, and began to sing and dance together with their crotches and so on.

I am willing to gamble and lose, I can't do it if I don't jump, and this place happens to be full of people.

After seven or eight repeated trials, each time the two copper balls landed almost at the same time, and under such irrefutable experimental results, everyone had to admit that two copper balls of different sizes and weights would fall to the ground at the same time when they fell from a high place.

Although everyone was curious about the explosion and asked Chen Xu to explain the principle to them, Chen Xu asked everyone to fulfill their promise first.

So there was a scene of this group of long-bearded men singing and dancing naked outside the east gate.

And a lingering and gentle year, it was ruined like this, and before it was finished, the hearts of many onlookers should be broken, especially those sentimental women and scribes who covered their hearts and gasped, and even more gray-haired Confucian disciples shook their heads and sighed that the world was declining, and morality had fallen to an outrageous level.

And the initiator of all this turned out to be the famous Qinghe Marquis.

But Chen Xu didn't care, he had been too busy and stressed recently, and spoiling this song and dance that he first created brought another refreshing sense of pleasure, lest he hear this song every day on the streets and alleys, and he was about to vomit when he heard it every day.

Outside the east gate, the bustle brought about by the test of two copper balls landing at the same time quickly dissipated.

But the excitement caused by this is still fermenting, and this experiment completely subverts the usual thinking habits, and many people who are not usually interested in messy things have begun to pay attention to the movements of the Academy of Sciences.

Especially two days later, a new issue of the newspaper came out, with a large special report on the scientific experiment of the two copper balls landing at the same time, this classic physical experiment will soon spread all over Daqin, and the unbelieving nature will go through the experimental verification on its own, and then there will be people who will conduct in-depth research on this subversive cognitive physical phenomenon, and then it will drive more people to be interested in physics.

However, as a result, there were also craftsmen from the Qinghe Marquis and the Academy of Sciences, and another bet also began to spread rapidly in Xianyang.

Countless people are excited to get together to discuss the most exciting topics of this winter, and many young women and mature young women even have red cheeks and hot bodies and begin to drool.

I don't know what kind of picture Qinghehou is looking forward to.

Almost all people who heard the news had their first reaction not whether Qinghehou would win, but how he would run naked.

Because as long as anyone who hears the content of the bet, they all feel that Qinghe Hou will definitely lose.

A car with two wheels in a straight line can't stand steadily, how can it be driven?

Therefore, everyone was full of anticipation and hoped that the craftsmen of the Academy of Sciences would quickly make the car called the bicycle, and then see the river marquis running naked.

But the guy who bet with Chen Xu began to be uneasy because of the test of two copper balls, and Zhang Cang and others also began to hope that the two-wheeled bicycle could be quickly produced, so many people invested great enthusiasm to study gear and chain transmission, and by the way, they also began to study different transmission methods such as belts, gears, connecting rods, and crankshafts.

Nima just rides a bike, what's all the fuss about.

Chen Xu's bet was just out of interest, and he didn't pay attention to it at all.

And in the past few days, I have taken the time to give lectures at the College of Engineering, the College of Agriculture and the Academy of Sciences, because it has been relatively idle recently, and he no longer needs to worry about repairing roads, and all the manpower arrangements for building bridges and roads are in place, Yang Kun is fully responsible, he is at most waiting for the planning of the places that need to be changed and straightened, and arrange people to put a few cannons, and gunpowder, recently the Nanshan Courtyard outside the city is being made in large quantities, plus the basement of the factory is also stocked with hundreds of catties, even if the black powder is not very powerful, but hundreds of catties and hundreds of catties down, It shouldn't be too much of a problem to blow up a few gaps on a few hills, not to mention that there is still a whole year to go, so Chen Xu is not worried at all.

Therefore, Chen Xu's main energy recently is to prepare for the wedding, because this time he wants to marry two wives at a time, which has become the most lively topic of discussion among the people of Xianyang recently.
