As the night passed, Evan regained his energy the next day, as if yesterday's events had never happened.

This relieved Audrey a lot, and she went to the crew with peace of mind.

Of course, when it comes to change, there are also changes.

Audrey felt that Evan was a little more pestering of herself, and her mouth was a little worse.

In the morning, when Audrey was preparing breakfast, Evan followed her from beginning to end, chatting with her and telling jokes that she couldn't get. When Audrey was aroused, the two naturally exchanged lips and tongues. Then when Audrey was "in love", Evan came to an abrupt end. Not only that, but he also scratched Audrey's nose and teased: "Don't worry, little pervert, are you still an adult?"

Thinking of this, Audrey, who was sitting in the taxi, was ashamed and angry, and spat Evan in her heart, "Damn, who are you talking about as a little pervert?"

After Audrey went out, Evan was in no hurry to get out.

He called Nina and told her when he would be back in Sacramento.

Then I made another call to Virginia, but no one answered.

Evan thought to himself that they should be out of the house, ready to fight again in the evening.

After that, Evan called Carl and Wells separately and informed them that he would not be going to the office today.

Then, Evan drove to Caltech.

There are not a few days left before Christmas, but there are still quite a few people who remain in school. Many parts of the school were lit up with the words "Merry Christmas".

Evan went to the building where the PME (Department of Physics, Mathematics and Electrical Engineering) was located.

As soon as he entered the hallway, Evan ran into Professor Watson.

If it had been yesterday, Evan would have turned around and left, but now, he's in the right place.

Evan greeted warmly, "Professor Watson!"

Watson was a little surprised that Evan was here at this time.

"Good morning, Evan......!

Evan said, "Professor, do you have time?"

Watson nodded, "I was just about to go to old Pasadena, but we can talk as we go." ”

Evan said it would work.

Evan had come to inquire about something. Watson is the acting director of PME, and there is no one more suitable to ask him.

"Professor, if I want to apply for a research project on my own, will the school allow it?"

Watson then understood what Evan was paying attention to, and he was a little unhappy.

He knew that Evan had excellent grades, but it would be too ambitious to do research on his own now.

However, in the face of Evan, Watson did not criticize directly, and still replied: "No, you are a student, and you can only do research under the guidance of your mentor before the training you have done is completed." It's the rule, it's the protection!"

Hearing this answer, Evan did not show great disappointment, obviously, he knew it. Then, Evan changed the question.

"Professor, which professor in our department, or in our school, is studying solid-state physics or semiconductors?"

"Are you interested in semiconductors?" Watson asked Evan a question first, and after receiving his affirmative answer, he replied: "Well, I think about it, semiconductors are not our department's specialty, and you know that there seems to be no one in the professors who specializes in this kind of research...... That's right......"

"There was a postdoc in solid-state physics named Robert Layton. Leighton), if you're really interested, you can talk to him. ”

After a moment's pause, Watson pulled out a small notebook and a pen from his coat pocket. The small notebook was full of names and contact numbers. Watson found Layton's phone, copied it on a blank page, added the address, and tore it off.

"Here you go!"

Evan took the note with both hands and said, "Thank you, Professor!"

Watson patted Evan on the shoulder and said earnestly: "Evan, in my opinion, you are only in the first grade now, and it is the time to absorb knowledge, and the research can be a little later. ”

"However, I also know that every genius has his own temper, so I won't stop you. ”

"But if you don't come to me because of this, I won't be accommodating. ”

"I see, thank you again, Professor!" Evan naturally didn't fail to understand the professor's kindness.

After half an hour of coffee with the professor in Pasadena Sr., Evan returned to school.

Instead of rushing to find Leyden, Evan went to the library first, checked Leyden's past published papers, and then went to PME to talk to a few teachers he knew about this person. After confirming that he was the right person, Evan went to his home in Leiden.

……

Robert Layton was born in Detroit at the age of 28 and moved to Los Angeles with his mother after his parents divorced. He attended Los Angeles City College in college and successfully transferred to Caltech in his junior year. He received his B.S. in Electrical Engineering, M.S. and Ph.D. degrees in Physics from Caltech, and is now a postdoctoral fellow working on face-centered cubic crystals.

Leiden is a generalist and very hands-on, and with a foundation in electrical engineering, he can even make his own experimental equipment.

Evan was particularly pleased with this.

Leiden's home was a bit far from the school, but he didn't choose to live there for the convenience of taking care of his mother.

Around three o'clock in the afternoon, Evan's car pulled up to his doorstep in Leiden.

Leiden's home is a modest wooden house, about the size of a house rented by Virginia. Of course, the location is much worse.

After checking the address on his opponent and making sure he was not mistaken, Evan walked up the steps and knocked on the door.

With a "squeak", the door opened.

It was an old woman who opened the door.

Evan smiled and greeted, "Good afternoon, ma'am, may I ask, is this the Leyden family?"

Polite people generally don't get too bad treatment.

The old woman looked at Evan quietly, nodded, and said, "Yes, young man, you are here to find Robert......"

Evan also nodded and replied, "Yes, ma'am, my name is Evan Warren, I am a student at Caltech, is Dr. Layton at home?"

"Here ......," said the old woman, getting out of the way, making a gesture to invite in, "Come in, since you are a top student at Caltech, you are welcome." Evan: yes, I'll call you Evan......"

"So...... Excuse me!" said Evan politely, and followed the old woman into the house.

"Evan, sit down!" Coming to the living room, the old woman pointed to the sofa and said to Evan, "Layton is in his studio, I'll help you call him." ”

After saying that, he left the living room and walked to the backyard.

There is a small independent house in the backyard, which is probably the "studio" in the mouth of the old woman.

In the meantime, Evan looked at the furnishings of the living room, an old radio, a gramophone, both on a cabinet with several trophies and a box of candy. Considering that the old woman is not expected to eat much sugar at her age, Evan guesses that it was left over from Halloween. The sofa seems to be newly bought. The coat rack next to the sofa was empty. Although Christmas is approaching, there is no Christmas tree in the house yet.

There weren't many things, but they were all spotlessly cleaned.

After watching the lap, Evan estimated that the Layton family should not be wealthy.

Not long after, amid the chatter of the old woman, a young man with a big back, wearing a white shirt and vest, with his cuffs rolled up, walked from the backyard into the living room.

"Hello, Evan Warren?"
