# Prof ST Yau’s 丘成桐 Talk to Chinese Youth on Math Education

Prof ST Yau **丘成桐** , Chinese/HK Harvard Math Dean, is the only 2 Mathematicians in history (the other person is Prof Pierre Deligne of Belgium) who won ALL 3 top math prizes: Fields Medal 1982 (at 27, proving Calabi Conjecture), Crafoord Prize (1994) , Wolf Prize (2010).

**Key Takeaways **:

1. **On Math Education**:

◇ Compulsary Math training for reasoning skill applicable in Economy, Law, Medicine, etc.

◇ Study Math Tip: read the new topic notes 1 day before the lecture, then after lecture do the problems to enhance understanding.

◇ Read Math topics even though you do not understand in first round, re-read few more times, then few days / months / years / decades later you will digest them. (做学问的程序).

◇ Do not consult students in WHAT to teach, because they don’t know what to learn.

◇ Love of Math beauty is the “pull-factor” for motivating students’ interest in Math.

◇ Parental Pressure.

3. Pi-Music: 1 = “do”, 2 = “re”, 3 =”me”…

Pi =3.1415926…

4. **Math Olympiad**: Prof ST Yau had criticised publicly it as a bad Math training, not the “real” Math.

An audience tested Prof ST Yau on a Math (Accounting) Puzzle which he couldn’t solve on the spot. He said Mathematicians are poor in +-×÷ arithmetic.

5. **Chinese students in USA**: China sends over 200,000 students to USA universities. They are good in secondary / high school Math with *known* solutions, but poor in graduate PhD Math which requires “**out-of-the-box**” independent thinking skill for finding *unknown* solutions. Recent few years Chinese students (eg. Stanford Prof 李骏 : 1989 Harvard PhD) in USA have improved standard in PhD research.

6. Research is not for fame. It takes many years to think through an interesting topic.

3. 丘成桐 (2008) 评中国 和 美 国的教育 : 中国学生不爱看课外书, 因为考试太重, 课余时间花在玩电脑游戏。

# Einstein’s Curved Space Gravity

Einstein showed by Mathematics (the Riemann Geometry) to explain Space-Time curvature and the Gravity. It was later proved by the astrological discovery in solar eclipse. (See video *)

Here, this professor made an experiment to demonstrate Einstein’s theory.

# Einstein & Riemann

Albert Einstein owed much to Riemann’s conception, saying that if he had not been acquainted with them

“I never would have been able to develop the theory of relativity.”

# Einstein’s day dream

1907- Einstein, a junior clerk recalled his ‘Happiest thought of my life’:-

“**I was sitting in my Patent office chair when all of a sudden a thought occurred to me: **

**If a person falls freely he will not feel his own weight. **

* I was startled. It impelled me toward a theory of gravitation.*”

=> The world changed by his ‘day dream’: Relativity Theory!
