In the autumn of October, with the increasingly hot atmosphere of the Tianfu Book Fair, the cultural atmosphere in Chengdu and even the whole of Sichuan became more and more intense. At 7:30 p.m. on October 18, Cai Tianxin, a professor of mathematics, writer and traveler at Zhejiang University, will be a guest at the "Hall of Fame" and give a lecture at the Sichuan Provincial Library with the title of "Qin Jiushao, Daoguqiao and China's Residual Theorems". During Professor Cai's entry into Sichuan, coinciding with the Tianfu Book Fair, in addition to attending the celebrity lecture hall in the Sichuan Provincial Library to lecture on Qin Jiushao, he will also go to Meizhou Dongpo Academy (2:30 p.m. on the 17th) and Fangsuo (7:30 p.m. on the 17th) to talk about childhood, university and hometown, and be a guest of Sichuan University and Chengdu Seventh Middle School to share with teachers and students.
Cai Tianxin is a professor and scholar with both arts and sciences. He is a professor in the Department of Mathematics at Zhejiang University, a doctoral supervisor, and a poet and writer. The Nobel Prize winner and famous writer Mo Yan once praised him: "Cai Tianxin's new brother was originally a high-caliber student in the mathematics department of Shandong University, and he is still obsessed with discovering the mysteries of numbers, and his poems and texts are also very well written, which is a small miracle." Bi Feiyu, winner of the Mao Award, said: "I like to read Cai Tianxin on the road, especially on the plane. His words are very much like the scenery outside the window, high, far, bright, or black. Cai Tianxin is tempting us to reverie. ”
Qin Jiushao (1208-1268) was a famous southern Song dynasty mathematician born in Puzhou (present-day Anyue County, Ziyang). George Sutton, the "father of the history of science," argues that "Qin Jiushao was one of the greatest mathematicians of his people, of his time, and indeed of all his time." Qin Jiushao studied astrology, musical rhythms, arithmetic, and construction, and his book "Nine Chapters of the Book of Numbers" was included in the "Yongle Canon" and the "Outline of the General Bibliography of the Four Libraries". Many of these calculation methods and empirical constants still have high reference value and practical significance, known as the "treasure book in arithmetic", representing the advanced level of Chinese mathematics at that time and occupying a lofty position in the history of world mathematics. Cai Tianxin, who has a systematic study of Qin Jiushao, is also curious about what kind of creation he has.
Cai Tianxin's works have been praised by Mo Yan and Yang Zhenning
Cai Tianxin's new works are abundant. In Mathematics and Human Civilization, he explores the relationship between mathematics and civilizations across different geographies and races, with different emphases, including Egypt, Babylon, Greece, China, India, and Arabia. During the modern period, he examined the relationship between renaissance art and geometry, the Industrial Revolution and calculus, and the French Revolution and applied mathematics. The exposition and comparison of modern mathematics and modern civilization is a feature of this book. In the classical section, efforts are made to discover highlights of modern significance. The book has won the title of "National Youth 100 Excellent Books". In 2019, the course "Science and Human Civilization" won the National Teaching Achievement Award. In "Mathematical Legends: Those Unattainable Figures," he used poetic language to introduce the great mathematicians of history to the public, winning the 2018 National Science and Technology Progress Award. The book has been well received by physicist and Nobel prize winner Mr. Yang Zhenning, "This is an excellent popular science book, with moving stories, in-depth insights, poetic feelings, and also describes the beauty and splendor of the mathematical kingdom." ”
In August 2020, Cai Tianxin's "Little Memories" by Life. study. Published by Xinzhi Sanlian Bookstore. This "little memory" is a record of the author from birth to the age of 15 before he was admitted to college. He unfolded the years that a boy had seen before us one by one. Born in Huangyan County, this polite and thoughtful boy returned to the county town after experiencing the difficult life of seven villages and a small town, and the story of the story shows us the picture of life in the village of South China in the 1960s and 1970s. The book intersperses the boy's adulthood, seeing the outside world, and comparing it with his childhood, dissecting the flaws in his personality and its causes, so that meticulous observation and broad vision blend.
In November 2021, the Commercial Press published Cai Tianxin's "Human Map of Europe" and "Human Map of the Americas", a collection of travel essays about 45 countries in Europe and 38 countries and regions in the Americas, a small series of books about Western culture. Different from the general travelogue, Cai's essays relate the present world with history and characters, and integrate the characteristics and history and culture of European and American countries, both objectively described and subjective feelings; coupled with the author's delicate brushstrokes, broad thinking, and depth and breadth, making his essay collection interesting and interesting, a set of popular works that understand Western history and culture. Cai Tianxin also edited poems such as "Poetry of the Subway" and "Poetry of High-speed Rail".
When a mathematics professor and poet interprets Qin Jiushao, what will he say?
It is very rare for a person to be proficient in both liberal arts and sciences and to be accomplished in both mathematics and literature. Professor Cai has a strong interpretation, promotion enthusiasm and unique analysis of Qin Jiushao, the sage, and his speech is also particularly exciting.
If you are interested in Qin Jiushao, a talented mathematician, you are welcome to sign up for this celebrity lecture hall and listen to Professor Cai's wonderful interpretation up close. This event will collect 120 on-site spectators and 4 volunteers (subject to the final organizer's phone or SMS notification), and the friends who love mathematical culture will come to the fast hand and register quickly!
In order to inherit and carry forward the spiritual character and temperament of Sichuan historical celebrities, highlight the contemporary value of historical celebrities, and promote the inheritance and development of China's excellent traditional culture, since the launch of the Sichuan Historical Celebrity Cultural Inheritance and Innovation Project in March 2017, Sichuan Province has announced two batches of 20 Sichuan historical celebrities (the first batch: Dayu, Li Bing, Luo Hong, Yang Xiong, Zhuge Liang, Wu Zetian, Li Bai, Du Fu, Su Shi, Yang Shen, the second batch: Wen Weng, Sima Xiangru, Chen Shou, Chang Xuan, Chen Ziang, Xue Tao, Gesar Wang, Zhang Yu, Qin Jiushao, Li Tiaoyuan).
The "Celebrity Lecture Hall" is an important cultural activity sponsored by the Office of the Leading Group for the Implementation of the Sichuan Historical Celebrity Cultural Inheritance and Innovation Project, the Sichuan Daily Newspaper Group (Cover News, West China Metropolis Daily), and the Sichuan Provincial Library, and is sought after by the majority of fans. Since the official opening of the lecture in November 2018, the "Celebrity Lecture Hall" has invited experts in the fields of history, humanities and natural sciences, including Li Jingze, Alai, Li Bo, Yu Dan, Mei Zhengzheng, Fang Beichen, Sun Xiaochun, etc., to sit and discuss with the audience, becoming a beautiful cultural business card.
