Humboldt-Universitat zu Berlin, formerly the University of Berlin, was the world academic center before World War II. Founded in 1810. It is a world-renowned top university and an elite university in Germany.

Humboldt University is the world's first new university that integrates scientific research and teaching. It has a very glorious history and is known as the "mother of modern universities". It has "integrated teaching and research", "academic freedom, teaching freedom, The Humboldt spirit of "learning freedom" has also affected almost all modern universities.

Humboldt University has a top reputation and strong research strength in the field of humanities. Its literature, neuroscience, philosophy, sociology, natural sciences and other disciplines are all ranked in the forefront of the world. Humboldt University's Law School is one of the best law schools.

　The walls on both sides of the hall are densely pasted with faculty name tags. Wilhelm stopped and watched with great interest.

Sure enough, he saw many well-known scientists from later generations.

Albert Einstein, Gustav Hertz, Erwin Schrödinger, Max Born... this school is simply an invaluable treasure trove.

Fortunately, he crossed early, otherwise god knows how many of these great people will escape from Germany in the future.

"Huh?" After watching for a while, Wilhelm frowned suddenly, stepped forward and reached out to tear off two of the name tags, and handed them to Annie beside him. "Go through the resignation procedures for these two people."

Annie was a little confused, did these two people offend His Highness? But Jannick continued. "Let them come to me tomorrow morning."

Annie can be said to be full of doubts. With so many famous people, why did Your Highness tear off these two? Looking down at the name on the name tag in his hand. Assistant Professor of the Department of Architecture: Albert Speer, Assistant Professor of the Department of Media: Paul Joseph Goebbels. Nothing special? However, these two guys were really lucky, and they were named by His Royal Highness personally, and it seemed that they were also the masters who were about to rise to the top.

"Let's find Dr. Einstein." After two steps, he stopped again and asked Annie. "Where is Dr. Einstein?"

Annie shook her head blankly. "Sorry, my lord, I don't know."

"Then you go ask."

Annie shook her head again. "Sorry, my lord, I have to guard your safety. When you go out, at least one person must be by your side at all times, and must not leave you even for half a step."

Wilhelm couldn't help rolling his eyes. In the original time and space, he was an ordinary man, how lucky he is to be treated like this. But this kind of blessing now seems to be troublesome. "Don't call me your highness when you are outside. Isn't this telling others who I am? You can't leave, I'll go and ask at the head office?"

Within a few steps, he saw a middle-aged man with glasses coming across. "Hello, Professor Schrödinger, do you know where Dr. Einstein is now?" Wilhelm was able to recognize the man in front of him at a glance because he had studied the "Schrödinger Pickup Method" for a while. It's a pity that I later found out that there is no money, no status, nothing will work. First of all, you have to have a girl who is willing to fall in love with you before you can use Schrodinger's law of cats to consider. Professor Schrödinger stopped, thought for a moment, and replied. "Dr. Einstein should now be teaching in the 310 lecture theatre on the third floor."

"Thank you, Professor." After thanking him, Wilhelm remembered something very interesting, and once again stopped Professor Schrödinger who was about to pass by. "Professor Schrödinger, I have a very interesting question that I want to discuss with you. Can I take a few minutes of your time?"

Professor Schrödinger nodded with a gentle smile on his face. "please say."

Wilhelm desperately held back the smile on his face, and said in a truthful way. "suppose a cat is put into a closed box, and a radioactive atom, a Geiger counter, and a poison gas release device are also placed in this closed box. Assume that the radioactive atom has a 50% probability of decay within an hour. When a particle is emitted, this particle will be detected by the Geiger counter, which will trigger the poison gas device to release the poisonous gas and kill the cat. Then, professor, will the cat be dead or alive in one hour?"

What Wilhelm is talking about is a famous thought experiment proposed by Professor Schrödinger himself, trying to explain the principle of quantum superposition at the micro-scale from the macro-scale, and cleverly determine whether the microscopic matter exists in the form of particles or waves after observation.

Listening to Wilhelm's explanation, the expression on Professor Schrödinger's face gradually turned into surprise, and then fell into contemplation.

Wilhelm was not in a hurry, waiting quietly, until someone called his name at the other end of the corridor. "Professor Schrödinger, Professor Schrödinger." Professor Schrödinger was relieved, and he opened his mouth with a little regret after waving his hand at the man. "This question is very interesting, but unfortunately I can't think of an answer for a while."

Wilhelm smiled disapprovingly. "Then you are welcome to visit me when you have time, and we will talk freely at that time. Miss Annie, give Professor Schrödinger a business card."

Annie shook her head awkwardly. "Master, you haven't printed your business card yet." His identity is very resounding, even if you don't know his name, you only need to report his surname or title. It must be known to everyone. Why bother making a business card?

She would never have thought that the body of the royal prince would be occupied by a soul that passed through decades later. He has not yet fully adapted to his status as the crown prince. He still follows the habits of the original time and space and never thought of showing off his noble status.

"Let me borrow your notebook." Wilhelm took the lesson plan from Schrödinger and wrote his name and address on a blank page.

Before Schrödinger had had time to take a look, the person at the other end of the corridor urged again. "Professor Schrödinger, hurry up, you are going to be late."

"..." Schrodinger nodded apologetically to Wilhelm, and walked quickly towards the man.

Seeing Professor Schrödinger's back, Wilhelm was very excited.

Before World War II, Germany was full of talents in the original time and space, but they were driven away by Hitler, and for nothing, a large number of excellent scientists were pushed to the United States on the other side of the Atlantic.

But in this time and space, there will be no more stupid things that persecute scientists.

Not only will there be no persecution, but he will also provide the best environment to support their scientific undertakings. After all, he quite agrees with the thesis that "science and technology are the primary productive forces" put forward by a great man. "Come on, let's go to Dr. Einstein."

Seeing that Professor Schrodinger, who was always on time, was almost late, the assistant teacher couldn't help asking. "Professor Schrödinger, what did you talk about just now? He doesn't seem to be a student of this school?"

Professor Schrödinger was full of excitement. "Very funny guy, he asked me a very interesting question, and I haven't figured out the answer yet."

The teaching assistant couldn't help being surprised. "Oh? What question can stump you, is it possible that he asked questions about history, geography or astronomy?"

Professor Schrödinger shook his head and repeated the question to his assistant.

The assistant was even more confused. "It's really interesting. It feels like a philosophical and a physical problem. Who is he? Can think of such a deep question?"

"By the way, he just wrote me an address and asked me to go to his home to discuss it." Professor Schrödinger opened his lesson plan and saw the name Jannick signed. "Wilhelm Hohenzollern?"

"wilhelm Hohenzollern?" The assistant was suddenly taken aback. "Isn't that the royal prince?"

Professor Schrödinger blurted. "Isn't his Royal Highness an unlearned playboy?" Because the court teacher hired by the royal family had a good relationship with him, he heard a lot of court gossip about the crown prince.

The assistant was startled and almost covered Professor Schrödinger's mouth. It was a matter of the royal family after all, and it was not the turn of ordinary people like them to gossip.

Professor Schrödinger also noticed his failure to speak, and looked around with lingering fears. After finding that no one noticed them, he was relieved and muttered. "Could it be that he suddenly got serious?"

The assistant asked. "Professor, when do you plan to visit?"

"..." Professor Schrödinger was a little troubled. He just wanted to concentrate on academic research, and didn't want to participate in any political circles, but now it is the future Emperor His Majesty who personally invited him to be a guest. If he doesn't go, it seems inappropriate. The most important thing is that the question raised by His Highness is really "interesting", which really makes him feel distressed.

Just when Professor Schrödinger was hesitating, Wilhelm had already arrived at the door of Lecture Room 303 on the third floor. The door of the classroom was not closed. Wilhelm identified the famous scientist on the podium at a glance.

Einstein always showed up with disheveled hair , giving him a rough and casual appearance. Many girls found it very fashionable and followed suit. But what was very embarrassing is that Einstein didn't think so, and the explosive head was not intentional by Einstein. The real reason was that he suffered from a rare disease called "difficult hair syndrome".

"Difficult to comb hair syndrome" is also called "puffy hair syndrome", also known as glass filament hair and triangular tunnel hair. It is an autosomal dominant genetic disease and was first discovered in 1973. People with this disease have dry, frizzy hair, lighter color, and super difficult to comb. As of April 2017, about 100 patients with puff syndrome have been found worldwide.

Annie asked softly. "His Royal Highness, do you want to call him out?"

Wilhelm shook his head. "Don't disturb him, we'll wait for him here." As they were waiting there for a while, Dr. Einstein obviously noticed them, maybe he will be moved when he knows Wilhelm's identity.
