近日，一则课堂上的“名场面”在网络走红——黑板上在演示求导过程，投影上却是古典诗词鉴赏。
Recently, a "famous scene" in class went viral on the Internet - the blackboard demonstrates the process of derivation, but the projection is the appreciation of classical poetry.
南京邮电大学周三证实，视频中这位备受赞誉的教授就是李雷先生，他正在教授《诗歌创作与鉴赏》这门课。通过运用数学原理来阐明诗歌的复杂结构。
Nanjing University of Posts and Telecommunications confirmed on Wednesday that the acclaimed professor is Mr Li Lei, who, in the video, was teaching his course "Poetry Composition and Appreciation" by applying mathematical principles to elucidate the intricate structure of poetry.
据了解，李雷是南京邮电大学数学教授，执教期间深耕数学和人工智能研究领域，并开设《诗词写作与鉴赏》课程，退休后仍担任《诗词写作与鉴赏》课老师。他的工作主要体现在现代数学专著《集值分析》和个人诗集《随心之语》上。
As a mathematics professor at the university, Li primarily conducts research in the fields of mathematics and artificial intelligence. He also offers the course "Poetry Composition and Appreciation" and continues to serve as the instructor for this course even after his retirement.
李教授曾任理学院院长、图书馆馆长、应用数学研究中心主任等多个职务。此外，他还是江苏诗词学会会员、南邮鼎山诗社顾问、信达国学社顾问。对于《诗词写作与鉴赏》课上出现数学演算的一幕，李雷老师说：“这一节课的内容是给学生们讲授诗的章法——起承转合。”在课堂上，他提到任何事情的处理都要经历起承转合四个阶段，例如人的神经系统、人工智能中的人工神经网络构造等。
Professor Li has served as Dean of the School of Science, librarian, and Director of the Applied Mathematics Research Center. In addition, he is also a member of Jiangsu Poetry Society, a consultant of Dingshan Poetry Society of Nanyou University, and a consultant of Xinda National Society. In the viral video, he was explaining the "exposition, development, turn, and conclusion" structure in poetry using mathematical calculations. He asserts that this four-stage process applies to various areas, including the human nervous system and artificial neural network construction in AI.
他认为起承转合中的“转”最为重要，人工神经网络的“转”常用高斯函数和S函数等函数运算，而诗词中，常用否定、疑问或强调等手法来体现“转”的环节。
He believes that the "turn" is the most crucial. In artificial neural networks, the "turn" is often achieved through functions like Gaussian and S-functions. In poetry, the "turn" is typically expressed through techniques such as negation, questioning, or emphasis.
在李雷老师的朋友圈里，他还经常用数学和诗词分享自己的生活，形容季节的变化，描绘身边的风景…
In Li Lei's circle of friends, he often uses mathematics and poetry to share his life, describe the change of seasons, describe the scenery around him.
不仅如此，李雷老师还曾在课堂上分别用楷书和行草以及两种书写形式板书他新写的诗——《枯荷》，同时融入思政元素进行三观教育。
Not only that, Mr. Li Lei also used regular script and herbal script and two forms of writing in class to write his new poem - "Gu He", while integrating ideological and political elements to carry out three-view education.
曾被评为学校最受学生欢迎的教师之一的李雷老师表示，“我一直以来的理念就是把教学做成艺术。教师不单纯是一个教书匠，也是一位艺术大师。”
Professor Li was once hailed as one of the school's most beloved educators. In an interview, he shared his enduring philosophy of elevating teaching to an art form, stating, "A teacher is not just a purveyor of knowledge but also an artistic master."
如今，尽管已退休，但李雷老师仍留在三尺讲台，与学生们分享着他的知识与见解。除了投身教学工作，李雷老师目前还是学校本科教学督导组组长和校关工委讲师团成员，从事着青年教师培养工作。
Today, despite his retirement, Li Lei remains at Sanchi, sharing his knowledge and insights with students.In addition to devoting himself to teaching work, Li Lei is currently the leader of the undergraduate teaching supervision group and a member of the teacher group of the school's customs Work Committee, engaged in the training of young teachers.
有数学的理性，有诗词的浪漫，这样的课堂谁会不喜欢呢！
There are mathematical rationality, poetry romance, such a class who will not like it!
该校学生表示，很喜欢李雷教授的教学方式，学习一门课的同时又收获一份了额外的知识。这不仅帮助同学们在古诗鉴赏这门课上开拓了新的学习方式，同时也实现了数学与古诗的跨学科的浪漫结合。
Students at the school said they liked Professor Li's teaching style and gained extra knowledge while learning a subject. This not only helps students to develop a new way of learning in the course of appreciation of ancient poetry, but also realizes the interdisciplinary romantic combination of mathematics and ancient poetry
古云：“师者，所以传道受业解惑也”。而李雷教授的这一堂课也许就是最好的诠释吧！
As the old saying goes, "Teachers, so preach and receive karma to solve doubts." And Professor Li's lesson is perhaps the best interpretation of it!
