# A Journey of Mathematics 数学之旅

Excellent free course for non mathematicians.

Welcome to the journey of mathematics
Do you feel mathematics hard to understand? Do you feel mathematics as abstract as mystery? Do you feel hard to grasp the key of Calculus? Do you feel at a loss when learning Advanced Algebra? From now on, you do not have to keep respectfully aloof from mathematics. Welcome to a relaxed course–The Journey of Mathematics!

This Philosophical Math course has started half way but past videos are still hosted on the site.

The course is taught by Prof Wang (王维克教授) of Shanghai Jiao Tong University上海交通大学 (SJTU), the Alma Mata of former China President Jiang (江泽民), Prime minister Chu (朱镕基), and Prof Qian XueSheng (钱学森) “The Father of Chinese Space and Missile” (China exchanged his country home return with USA FBI for 4 American generals from Korean War prisoners of War) who sent Chinese ‘Taikongnauts’ (太空人) to space.

SJTU was formed initially as the ‘Classe Préparatoire’ (Bachelor degree, post-High school Prep-college) for graduate engineering to MIT;  while Qing Hua (清华大学) University was a prep-college for graduate Science/ Math to Harvard, Chicago, Cornell,  etc.

Go to Lesson 3: He explains from a game of Go what is “Space” in maths: Geometrical 3-dimensional Space, Linear space, Vector space… why study Functional space (in  which functions are treated like points in that space). The notional difference of Distance (D) and Norm  (N 范数): N=>D , but converse not true.

是否曾觉得数学晦涩难懂？是否感叹过数学抽象如天书？是否在学微积分的时候不得其要害？是否在面对高等代数时不知所措？现在不用再对数学敬而远之，一场轻松的《数学之旅》课程在欢迎你！

在这场旅行中，我们将一同回溯过去，去和古代的数学大师对话，探索最初的数学思想如何萌芽；我们也将飞越历史的星空，与牛顿、莱布尼兹一起，亲眼见证那“英雄时代”的科学奇迹；我们也将会踏入“陌生的国度”，去欣赏数学所表现出的人类心智的荣耀；我们也有机会亲手一试，看数学如何成为我们思想的武器。你将体会到抽象不是天书的代名词，而是引领我们理解世界的天使；严谨不是数学的无事生非，而是通往真理的捷径。旅行中我们将一起充满好奇地欣赏数学的魅力。

快点击选课吧！一路有我，一路有你，《数学之旅》期待你的加入！

Welcome to the journey of mathematics
Do you feel mathematics hard to understand? Do you feel mathematics as abstract as mystery? Do you feel hard to grasp the key of Calculus? Do you feel at a loss when learning Advanced Algebra? From now on, you do not have to keep respectfully aloof from mathematics. Welcome to a relaxed course–The Journey of Mathematics!

During the journey, we will look back upon history, talk with ancient mathematicians and explore how initial mathematical thoughts germinated. We will also witness the scientific miracles of Heroic Age together with Newton and Leibniz. We will step into a “strange country” and appreciate the honor of human mind embodied by mathematics. We will have a chance to understand how mathematics becomes the weapon of our thoughts. You will know that abstractness is an angel who helps us understand the world, not a mystery. Preciseness is the short-cut to the truth, not a trouble made by mathematics. We will appreciate the glamour of mathematics with curiosity.

Click the select button! We are companions along the way. The Journey of Mathematics is looking forward to your participation!

Yours truly,
Instructor Wang Weike,
