Amid the noisy chatter of Professor Negri.

Professor Weissman still glanced at Professor Naigri calmly, and continued, "Dear Professor Naigli, I do not agree with your explanation. I think that the genetics of plants proposed by Dean Mendel are also applicable to animals. I must admit that you are older than all of you here, but whose hands are the truth has nothing to do with age or seniority. I insist that heredity is a chemical exercise, not a mathematically constructed equation of matter. As for my teacher's theory"

"I remain convinced that we don't know and won't know."

Everyone was dumbfounded, but they didn't expect Weissmann, a weak middle-aged man with glasses, to have such a hard personality.

For the world's biologists and botanists in 1879, Mendel's laws of genetics published in 1865 by the abbot Mendel, and his paper "Experiments on Plant Hybridization" published in German the following year were too far ahead of their time! His views were accepted by the world 34 years later, in 1900.

Joy watched this controversy and knew very well that Professor Negri's theory was completely wrong, and that all the genetic research of the twentieth century had proved the accuracy of Mendel's theory. Later scientists found the miraculous double helix structure in the cells of plants and animals, which finally confirmed the greatness of Dean Mendel's genetics theory.

But looking at this controversy, Joey has a sense of force that he cannot use the results of decades to support Professors Augusta Weissmann and De Vries, who he believes are correct.

But people who read psychology will always be good at transforming some nervous emotions.

Joey interjected with a smile, "The heated debate of the professors and gentlemen is really wonderful, and we should all applaud and thank you for listening to such a wonderful debate." ”

After a round of applause, the tension between several parties was obviously relieved. Joy continued with a smile, "Since Count von Humboldt advocated academic freedom, Germany has been in favor of all free academic thought, and I thank several professors and gentlemen again for their unfettered free ideas. Joy bowed again to the professors who had been arguing fiercely.

"Today we heard from Prof. Negri's principle of internal self-improvement, as well as from Prof. Weissman's germplasm theory, both of which are refreshing. I was also interested in Dean Mendel's theory of genetic factors. I would like to announce that the Crown Princess Victoria Fund will sponsor the implementation of these ideas, in particular Professor Weisman in the field of animals and Dean Mendel in the field of botany. Of course, if several people are willing to conduct research in the field of flora and fauna at the same time, the Foundation is also in favor of it. ”

Joy paused for a moment to digest his speech before continuing, "All research has only one condition, and that is to clarify the application prospects. For example, Dean Mendel's peas have been artificially bred and selected, and the second and third generations are obviously different from the first generation's merit-based selection, and if we can make Germany obtain better crop seeds through rational artificial breeding, then this is the application prospect that I am looking forward to. ”

"So, Your Royal Highness, the expectation of your funding is to get better plant seeds?" Professor de Vries asked.

"Yes, Dear Mr. De Vries." Joey replied with a smile.

"Or a stranger canine? But isn't that what a veterinarian does?" interjected Professor Weissman with a calm face.

After hearing Professor Weissman's words, Joey helplessly remembered some of the precious dog breeds artificially bred in later generations, "Great God, do you want me to take the route of pet dog training?!" At the very least, we need to develop better genes for better cows, horses and pigs! ”

The only downside to communicating with like-minded people is that there is always not enough time, and it is getting late in Berlin in the spring, and the time for the salon to end is approaching.

Near the end of the day, Joey finally met the famous Professor Richthofen.

Professor Richthofen was the first person in the world to propose the theory of the Silk Road, and Professor Richthofen looked at the Silk Road differently from his successor, Sven Hedin. First of all, according to Professor Richthofen's investigation in China, it was legal, and it was approved by the Qing government; Secondly, Professor Richthofen's expedition in China was at the level of geological science, not Heding's set of rules of the game. In the end, he was actually the first person to scientifically investigate the geology of China, and he also gave China the geological situation of China after the investigation.

In commemoration of Professor Richthofen's actions, the Qilian Mountains used to be called the Richthofen Mountains.

Of course, Professor Richthofen was a determined, determined, committed German patriot.

After communicating with Professor Richthofen and their students, Joy asked his parents to arrange for them to have dinner together. He also agreed that after dinner, the crown prince would set aside an hour to communicate with Professor Richthofen alone.

The salon's final job was to send the great German gods out of the door and watch them depart in a carriage. Joey followed his parents, outside the foyer of the palace, and made a very decent appearance.

Beatrice Marina Louise Vismann accompanied her aunt, her aunt's friend Empress Augusta, and a group of young ladies from the German royal family to spend a wonderful spring time in Wannsee. Especially after meeting Queen Augusta's two lovely granddaughters, Princess Alice and Princess Fiodora, Mary remembered the stupid duck she had met in the Hall of Mirrors of the Charlottenburg Palace the day before yesterday.

Whether on the way to Wannsee or during a picnic, Princess Alice and Princess Fiodora were arguing about a magical boy, starting with whether the boy should adopt a white owl or a white cat, and continuing to where Diagon Alley was in London, and whether there was a 9 and 3/4 platform at King's Station, where they had been with their mother when they visited their grandmother in London the year before.

In general, almost the entire journey of the two princesses was spent in the process of lifting each other's bars and tearing down the stage. But at the end of the Wannsee Spring Outing, to everyone's surprise, the two princesses were reconciled again, because they had finally reached a high degree of agreement on the matter of the Sorting Hat.

Mary spent the whole spring outing with the two princesses, and with the help of listening to their arguments and asking questions, Mary almost fell in love with the magical boy with a lightning scar on his head and his adventures. Because Mary has also lived in London for a long time, the speculation about the location of Diagon Alley and the accurate description of Platform 9 of London Railway Station also made the two princesses feel good and regarded them as confidants, and then they have the momentum to become close friends.

In the afternoon, everyone began to return to Berlin from Wannsee. Because Mary and her aunt stayed at the Hotel Roma on Bonnstraße in the city of Berlin, close to the Womb, Marie and her aunt sent them back to the Womb on the way back to the city. Marie and the two princesses huddle in a carriage and continue to discuss the magical boy's bizarre journey, as well as the impressive candy and food items.

When the carriage stopped at the street under the linden tree next to the palace, Mary said helplessly, "It's a pity that the time is so fast, I hope to continue this topic with you." Then he clenched his little fists and stomped his feet, looking at the two princesses expectantly, "Dear Sophie and Margaret, can you tell me who the author of this book is?" And where did you buy it? I'll just wait and buy it, it's called Harry Potter, right? I can't wait to read this book! ”

Princess Alice and Princess Fiodora suddenly looked at each other with a little weakness, and only now did they remember that the thing they had been arguing about for a day was the bedside story that her brother told them.

Princess Alice was a little bolder, stretched her hand out of the car window, pointed to Joey, who was seeing off the guests at the door of the palace, and whispered, "My brother is the author, and he just told this story... Oh, it's written to the Sorting Hat. Dear Mary, you are the first person besides my sister and I to know about this, and my brother said that this story was a gift to my sister and me, and that it needs to be kept secret from outsiders. ”

Princess Alice looked at Mary and then at her sister, "But my sister and I don't think you're an outsider, you're a good friend of ours." Tomorrow we have a dance party at our house, and Mom says we can invite our friends, dear Mary, would you like to come? ”

"Dear Sophie, I need to ask my grandmother's permission, and of course I would love to come." Mary replied with a happy smile.

"Goodbye! Dear Mary, we have a great day with you. Then Princess Alice and Princess Fiodora hugged Mary goodbye, jumped out of the carriage, and ran back to her parents and brother in the womb.

Mary looked at Joey standing at the door of the palace, smiled with big blue eyes, and said in her heart, "Hmph, you stupid duck has a lot of secrets!" ”

Joey sneezed inexplicably.
