Bo Jue's reputation in history is not too big, and the information recorded in the history books is also limited, but in the Chongzhen period to help the governor Zhang Guowei make copper cannons, after many tests, the copper cannons made have high precision, advanced structure, and the cannon is equipped with a clairvoyant mirror, which improves the hit rate. He also made waterwheels, firearms, crossbows, and other instruments. Its superb machinery manufacturing technology has a great impact on the development of the manufacturing industry in the Susong area in later generations.

This Fang Yizhi is not simple, he is a native of Fengyili, Tongcheng County, Anqing Prefecture (now Zongyang, Anqing), and was born in a family of scholars. The Fang clan was the main clan in the Tongcheng area during this period. Great-grandfather Fang Xuegradually, proficient in medicine, science, and can learn from the hundreds of schools, comprehended, self-contained, in addition to recording the "Journey to the East" to Donglin lectures, the author of "Yi Li", "Sex Good Interpretation", "Tongyi", "Training", "Tongchuan Language" and so on. Grandfather Fang Dazhen in the Wanli years, once served as Zuo Shaoqing of Dali Temple, and wrote hundreds of volumes such as "Yiyi", "Poetry", "Rites", "Yongsilu", "Youzhonglu" and so on. Because Fang Xuegradually learned from Geng's theorem of the Taizhou School, the "Ming Confucianism Case" included him in the "Taizhou School Case". His maternal grandfather, Wu Yingbin, was proficient in Confucianism, and wrote "The Complete Works of Xueyi", "Commentary on Xueyong", "Treatise on Zongyi Sheng", "Trinity Zhai Manuscript" and so on. Father Fang Kongzhao, Wanli forty-four years of Jinshi, Chongzhen Dynasty official to Huguang governor, through medicine, geography, military, and early contact with Western learning, advocating the study of the knowledge of the world, author of "Zhou Yishi Treatise", "Quanbian Brief Notes", "Shangshu Shi Treatise" and other works such as "Quanbian Brief Notes", "History of the Ming Dynasty" has a biography. "Zhou Yishi Theory" was included in the inventory list of "Four Library Synopsis". This book had a great influence on Fang Yizhi, and Fang often mentioned it in his life.

Fang Yizhi's introductions were found on the later generations of Du Niang, and the more famous thing is that he was one of the four sons in the late Ming Dynasty, with a wide range of friends, suave and suave, and quite famous in the Jiangnan of the late Ming Dynasty, and Hou Fangyu in the legendary script "Peach Blossom Fan", Zhu Youxiao also knew Fang Yizhi in the script of "Peach Blossom Fan", and firmly remembered this name, of course, this is still when Zhu Youxiao was in high school, scholarly spirit, and the age of pointing the country.

Originally, Zhu Youxiao thought that this guy didn't know where to be dashing, but he didn't expect that it was right under his nose, it seems that many celebrities in the late Ming Dynasty should be able to find it now, like the fourth prince and the like, maybe they can be made into useful talents, go back and let the officials check it out, see what these merry boys are doing now, and they will roll over for me to work hard for Daming.

Bo Jue's proof method is that he used the electrolysis concentrated brine experiment, and the * and hydrogen obtained were tested in the same volume, because only a very small amount of gas was used, so the natural quartz was used as a nozzle to burn the hydrogen in the * through the glass tube, and finally the test tube was filled with the same amount of water, so that the number of molecules contained in the same volume of gas was the same.

And Fang Yizhi's proof is even simpler, he didn't even do the experiment, and directly used theory to illustrate this problem, the example is Zhu Youxiao's own explanation of electrolysis of water, since it is two hydrogen atoms and an oxygen atom combined to form water, then the electrolysis of hydrogen is naturally twice the volume of oxygen, but as for why water is composed of two hydrogen atoms and one oxygen atom, this is based on Zhu Youxiao's statement. So Bo Jue and Fang Yizhi divided the 10,000 taels of silver equally, and they were all overjoyed, and the other students who were envious asked the two to invite them to dinner.

In fact, Zhu Youxiao's statement is not quite correct for everyone to verify itself, because the problem of chemical valence is also designed here, but in order to let everyone remember this Moore abstract noun, this is such a somewhat wrong question. As for the issue of chemical valence, Zhu Youxiao will not let everyone understand even if he tells these students now, and these can only be explored slowly in the future development.

You can do this to others, but you can't do this to Bo Jue and Fang Yizhi and Zhu Youxiao, which will mislead their future research work, so Zhu Youxiao specially left these two people and added a small stove to them, so that they could move in the right direction. Judging from the performance of the two of them, Fang Yizhi pays more attention to theoretical reasoning, and Bo Jue focuses on specific practical experiments, which Zhu Youxiao speculated during the lecture, and now this "Moore" noun proves Zhu Youxiao's calculation.

In Zhu Youxiao's study, Bo Jue and Fang Yizhi sat on both sides of the main table with some flattery, after all, they were both seventeen or eighteen-year-old children, and they were indeed a little surprised to accept the emperor's teachings directly, Zhu Youxiao didn't care what their mentality was, so he slowly began to tell his story.

"What I'm telling you about may be a hypothesis, but you'll need to figure it out for yourself. I think that atoms are the basis of all matter, but atoms may not be the most basic particles, they are composed of smaller particles, just like people are the smallest unit of society, but everyone is different, we compare atoms to a person, atoms can be divided into specific people and clothes, specific people become protons, and clothes become electrons, relative to the weight of the human body, the weight of clothes is negligible, and the weight of electrons is negligible relative to protons, Like the human body, everyone wears different clothes, the atoms have different electrons, and the weight of the atoms will not be the same, just like some families are big and some families are small, and some may be relatives who will live in other people's families, just like every piece of clothing is worn on the body for warmth, and the electrons are also surrounded by the outside of the protons, but it is rotating at high speed, and the extremely high-speed movement around the protons is basically stable under normal circumstances. But when it is disturbed by the outside world, it can change, just like people need to get married, and they fight for clothes, and two different atoms will undergo different and various changes. The hydrogen we make, it is the most basic unit of all atoms, there is only one proton and one electron, while oxygen is composed of eight protons and eight neutrons, neutrons are relatives, protons are positively charged, electrons are negatively charged, electrons move around protons and neutrons at high speed, generally very stable, and when the external environment changes, it is possible to change. Let's take water as an example, there is only one electron outside the hydrogen atom, and there are eight electrons outside the oxygen atom, but the electrons of the oxygen atom are divided into two layers, the inner shell is two, and the outer shell is six. Eight in the outer layer, it's like forming a new stable family, unless it is disturbed by an external force, such as electrolyzing water, like destroying their family. There are countless such struggles in the natural world, and these things can never be finished, but we first hypothesize these phenomena and then confirm them. ”

These incomprehensible theories made Zhu Youxiao explain to the two of them in extremely popular language, and his mouth was dry, and he didn't know how the two of them listened. Seeing that Bo Jue is mouth is wide open now, he was a little surprised when he estimated, but Fang Yizhi was closing his eyes and thinking deeply, as if he had realized something. This is not something that can be understood in a while, they need to digest it slowly, and when they understand, they will naturally study it in depth. In order to make it easy for them to study, Zhu Youxiao still defined them according to the units he had learned, that is, grams, kilograms, meters, and centimeters, which can reduce a lot of calculation processes.

After a period of study, Zhu Youxiao set up a table according to the periodic table of later generations, filled in some elements that are now known, and then told them that this table is called the periodic table, and the specific gravity of many things can be roughly calculated according to this table, and it can also be seen that those things are more active, those are more inert, or those things can be manufactured through electrolysis, and those can be replaced by something, in short, this is Zhu Youxiao in order to promote the scientific and technological development of the Ming Dynasty as soon as possible, I did a lot of disadvantages for a while, anyway, these things will be studied in the future, which can save you trouble, so why let them grope in the dark.
