The pet mink was very depressed, who knew that the cucumber was such a thing, not to mention the green one, there were thorns on the body, what kind of thing, I would not betray Tang Chuxue if I knew it, and continued to call Dabai.

So at the banquet that day, this product licked his face and returned to Tang Chuxue's side, and let the Tang goddess smash a few chestnuts and still sell cute and coquettish, seeing the small pompoms and pink complaints, to talk about the thickness of the face of the star leading demon beast, this product should be the first.

The reception banquet was very lively, and the middle and high-level executives who came to participate were excited, almost all of today's ingredients were demon beasts, and they were enough. Although the lord has also rewarded more advanced demon beast meat in the past, how can he shake off his cheeks and eat comfortably now.

Old man, Zhao Danqing, the people of the earth-shattering mercenary group listened to the second brother's mouth foaming at the mouth about the battle in the vast depths, and their eyes lit up one by one, and they really wanted to drag Jiang Xingchen to go again.

During the banquet, people talked and staggered, and the monsters were also in different forms. Dabai and the fox, who changed their names back to eating, didn't care about what image they ate, they were all twenty-nine level demon beasts, and they often hunted low-level demon beasts, so it can be said that they all grew up eating demon beast meat, but compared with what they eat now, what they ate before was simply garbage.

Crabs, small pompoms, pink, and spirits looked at the twenty-ninth level demon beast whose two heads were pierced into the food bowl, and their faces were full of contempt: "I really haven't seen the market, turtle!"

Even Tofu and Beauty couldn't bear to look at the two monsters and turned their heads directly. The little circling eyes are straight, this food is unbearable compared to himself!

The old village was even more lively, and the little white horse was about to jump on the roof excitedly, and Jiang Xingchen sent someone to give it a plum blossom stamen. This is a high-level genius treasure, and all the beasts, no matter how big or small, are envious. Even Hei Dian and Ziyun were red-eyed.

After eating a meal late at night, Jiang Xingchen was dazed. The words were not neat, and they were so angry that Xian Ning pointed at the old man and they counted for a long time. She still wants to talk to Jiang Xingchen.

The night in mid-October was already very cold, Mei'er helped Jiang Xingchen take a hot bath, helped him to the bed, hugged him and covered him with a quilt, and watched his sleeping face gradually become distracted......

Jiang Xingchen slept in the dark this night, and didn't wake up until the next day, only to feel tired and energetic.

The side is empty, and this time Mei'er should have gone to the municipal work. Jiang Xingchen jumped off the bed. Wash your face and rinse your mouth and eat something casually, and then go straight to the university.

Entering the university, Jiang Xingchen felt like a world away, as if he had returned to the campus of his previous life. Walking along the boulevard, he couldn't help but slow down, wanting this experience to last longer.

I don't know how long I walked, the sound of the rattle came into my ears, and Jiang Xingchen suddenly woke up and saw that he had arrived at one of the teaching buildings. It has been six years since these children came to the Star Leader, the older ones are more than twenty, and the younger ones are in their teens.

"Hello sir. ......The students greeted Jiang Xingchen one after another when they saw Jiang Xingchen, and everyone was grateful from the bottom of their hearts, if they hadn't come to Xingchen Ling. They will never be able to get rid of their slave status in their lives.

Jiang Xingchen nodded with a smile, full of relief. These are the hopes of the future of the stars!

All the way to the laboratory, Jiang Xingchen found Xianning. She was lying on the table and reading a book, but she didn't notice Jiang Xingchen's arrival.

"What are you writing?" Jiang Xingchen didn't say anything, and quietly came to Xian Ning's side, looked down, and suddenly smiled.

"Xian Ning, the gravitational acceleration has been measured!" Jiang Xingchen asked excitedly.

"Oops!" Xian Ning almost threw away the pen in his hand, turned his head to see that it was Jiang Xingchen, raised his hand and slapped him on the arm: "Why don't you even make a sound when you walk, it's like a ghost!"

"Who said I didn't have a voice, you yourself were too serious to hear it!" Jiang Xingchen rubbed the place where he was beaten, and immediately asked, "What is the result of the measurement?"

As soon as she said this, Tang Chuxue's expression became serious: "It's very laborious! With the single pendulum method you said, the pendulum length is easy to do, mainly because of the periodic measurement, and the error generated by observing the clock is a bit large! In addition, there is also the problem of single pendulum rotation...... Thankfully, Nier used trigonometric functions to help solve the ......"

Jiang Xingchen was dumbfounded when he heard this, there are many ways to determine gravitational acceleration, but he remembered that the single pendulum determination seemed to be introduced in the middle school textbook, but he didn't expect it to be so complicated.

"I recorded thousands of experimental data, and finally came up with an average, but I still can't guarantee this data. Xian Ning said.

Jiang Xingchen nodded: "No matter what, it was finally measured, and the final result ...... Twelve .3 meters per second squared!"

Seeing Xian Ning's final conclusion, Jiang Xingchen was very surprised, but then he was relieved, after all, it was a different world, how could it be the same as the earth.

"Now I'm pushing the formulas you gave! To be honest, you really go against science, the derivation of every quantity is derived through experiments, how can you give the formula first! Have you done these derivations before!" Xian Ning asked curiously.

Jiang Xingchen touched his nose and smiled bitterly, he didn't want to directly give out the relevant formulas of middle school exercise and force, but if this is a little bit of research, how long will it take, it is better to take out the crystallization of these predecessors' wisdom and use it. Anyway, everyone knows that they have secrets.

For example, Zhou Lin told me that his calculations would be very difficult if he didn't have a mathematical foundation. And the problem of variables that you told Nile about before, it can be used in the current laws of mechanics, especially in the case of change, and Nier's side has progressed to differential calculus......"

Jiang Xingchen was happy to hear the recent development, but he could only listen, he couldn't explain anything to Xian Ning.

Fortunately, Xian Ning didn't dwell too much on this, and then talked about the results of the research institute. What made Jiang Xingchen excited was that someone had already raised the issue of energy conversion. For example, a steam engine converts thermal energy into mechanical energy, and begins to observe things such as pressure, volume, temperature, and system state in the process.

"Isn't this the study of thermodynamics!" Jiang Xingchen was very happy, thinking about whether to go back or write out the laws of thermodynamics for those researchers to guide them.

Not to mention, under the leadership of Xian Ning, the researchers have summed up a number of chemical reaction laws in more than a month, especially redox reactions, displacement reactions, and the use of some catalysts.

To Jiang Xingchen's surprise, there were several other research institutes that had already proposed the role of Yuan Qi in chemical changes.

The more Jiang Xingchen listened, the happier he became, the achievements of the institute are huge, the complete education system of mathematics, physics and chemistry has basically been formed, and the disciplines will be more complicated in the future, and the research will be more refined, especially after adding electricity. The prelude to the great development of the whole world, or the whole world, will slowly open.

Jiang Xingchen talked with Xian Ning for a whole day, and it didn't end until evening. Before leaving, Jiang Xingchen said to Xian Ning, "Do you remember that I promised you an experiment?" (to be continued......)

PS: It's too late, let's write two thousand first! In the afternoon, garlic strives to write four thousand, but I dare not guarantee it!
