In the afternoon of May 13, accompanied by classics and famous works, the cloud sharing meeting for teachers and students jointly read was held on the online platform hosted by the University's science and engineering Party committee and the student work department and organized by the Youth League Committee of the school of physics and electronic science. Hu Bingwen, vice president of the school of physics and electronic science, and Wang Tao, associate professor, as the guide, gathered in the cloud with more than 120 teachers and students from the whole school to read the brief history of time. Wang Yuanli, Secretary of the Youth League Committee of the College of physics and electronic science, presided over the meeting.

In the reading guide, Wang Tao analyzed the readability and popularization of the brief history of time by comparing with the famous works such as dream of the red chamber and the book of changes. After that, he elaborated the book's academic views from three aspects: version difference, specific content, cosmology and so on. Wang Tao pointed out that the book is mainly divided into several modules of relativity, quantum theory, cosmology, black hole science and string theory. The first two modules correspond to the two great achievements of physics in the 20th century, and the last three modules contain Hawking's own academic achievements.In the interpretation of cosmology module, Wang Tao introduces the process of the origin and expansion of the universe in a brief history of time, and vividly explains the concepts of the singularity and virtual time of the universe elaborated by Hawking in the book. At the same time, Wang Tao also shared his original views on the classic works: we should not only feel the author's thoughts from a macro perspective, but also insight into its subtleties from a micro perspective, so as to achieve the state of knowing and laughing happily.

Part of the introduction

Hu Bingwen introduced three grand questions of what is the universe, where the universe comes from and where the universe will go in a brief history of time, and discussed the metanarrative problem of physics with his classmates. A brief history of time reflects on the birth and origin of the universe from the perspective of time, introduces a lot of knowledge related to stars, puts forward the basic concept of black holes, and tries to explore its mystery, which is lively and thought-provoking.Hu Bingwen said that in terms of thinking mode, the book has established reasonable hypotheses and carried out mathematical reasoning and experimental verification, which can help us deepen our understanding of the vast universe. Even if this understanding is still incomplete, we can also carry out more in-depth exploration by improving hypotheses and models, which enlightens us: the Research of physics requires us to be artistic Fantasy, we also need to do down-to-earth experiments and theoretical deduction.

Part of the introduction

In the interactive communication, the students shared their experience in reading the brief history of time, and had in-depth communication with the two readers on the origin of the universe, whether there is parallel space-time, the hypothesis of the big bang of the universe, and the application of quantum mechanics in life. The way of sharing and discussion between teachers and students made the students understand how to read classic masterpieces and adjust their thinking We have a deeper understanding of the study of formal and innovative learning.

Despite the novel coronavirus pneumonia epidemic, students can not read and discuss together with teachers in normal university campus. However, the teacher and student shared the cloud to set up a bridge for teachers and students to collide and communicate with each other. Through the sharing of the two guidance readers, the students harvested the methods of exploring the physical world and perceiving academic frontiers.”Pursue the light and clear ambition”，the college will further expand the online and offline communication platform between teachers and students, give full play to the education function of classic reading, and let teachers and students read classics together become an effective channel to cultivate the feelings of home and country, cultivate scientific spirit, and improve human quality.
