Just when the physics community around the world was turned upside down by this paper, Professor Edward Witten was leaving.

Since completing this paper, Professor Witten felt that his energy was too much. In addition, Qingmu University was also on holiday, so he returned to the United States with his wife, intending to take a long vacation, and then come to Xia Country after feeling relieved.

Together with Qin Ke and Ning Qingyun, they continued to improve the project of string theory.

Professor Karen Uhlenbeck also felt deeply that Ning Qingjun's "growth" had exceeded her expectations. She was satisfied with the end of this academic tour that far exceeded the original schedule, and planned to fly back to the United States with the Wittens.

.

The separation time is scheduled for the day after the thesis is completed.

Qin Ke hugged Professor Witten and said, "Edward, remember to come back."

"Don't worry, there is nothing in the world that would be more pleasant than working with you." The old gentleman smiled.

Over there, Professor Uhlenbeck was also saying goodbye to Ning Qingyun.

The old lady never mentioned that she wanted Ning Qingyun to take over her "baton" and become a new generation advocate and leader for women to study mathematics in the international mathematics community. Only when they finally separated, the old lady said

Sentence: "Ning, you are the best female scientist I have ever seen in mathematics and physics. I wish you continue to move forward on this path and create new brilliance."

Ning Qingyun is a typical person who is cold on the outside and hot on the inside. She seems cold and a bit withdrawn, but as long as others are kind to her from the bottom of their hearts, she will develop feelings for her.

In the past four or five months, Professor Uhlenbeck has treated her as both a teacher and a friend, selflessly sharing his lifelong learning and experience with her, which has benefited Ning Qingyun a lot and she has long regarded him as her teacher in her heart.

At this time, when he saw the old lady's gray face and white hair, her waist was already a little rickety. After saying goodbye today, she didn't know if there would be a chance to meet again in the future. Ning Qingyun's eye circles suddenly turned red, and tears rolled in her eyes. She couldn't say a word.

Unable to speak.

Seeing Ning Qingyun's look, Professor Uhlenbeck's originally stern face also changed. She stretched out her hand and shook Ning Qingyun's hand vigorously:

"I don't have any special hobbies in this life. What I like most is mathematics. I figured it out blindly. I am a little proud of my elementary school knowledge and experience. I am always afraid that it will just die with me. Mathematics... sometimes it is conveyed by words and calculations alone.

No, especially the way of thinking. It is like the Higgs field. Only by causing spontaneous symmetry breaking can the mass be transferred to canonical propagators and fermions. The way of thinking can only be transmitted through heart-to-heart communication. Thank you

You, Ning, hope that my mathematical way of thinking can bring a little help to you and all female scientists. Goodbye, my dear friend, this trip to Xia Kingdom will be the best memory in my life."

The old lady finally opened her arms and hugged Ning Qingyun, then turned around and got into the car, leaving Qingmu University with Edward Witten and his wife.

Watching the three familiar elders go away, Ning Qingyun finally couldn't help it, and tears rolled down her face.

Qin Ke stretched out his hand, put his arm around Ning Qingyun's delicate shoulders, and said warmly: "What an amazing old lady."
