Alot of Theories from Chinese actually did not recorded down properly. 五千历史其实不是盖的。
Machiam, AngMohs were the ones who came out all the theories.

The Chinese has a very bad culture on passing down the knowledge. 宁愿失传,也不传外人。 crying

There is one interesting one like 关羽刮骨疗伤。
The physician who treated 关羽 was not 华佗 actually. Rotfl 因为华佗already uplorry.
Why the author 罗贯中 wants to tell a lie?

过五关斩六将也是虚的, 不是真的。

关羽手握青龙偃月刀 也是假的。

真假不分才是最可悲!

当然,是路痴的只能是读者,啊不,只能是作者。在三国的正史当中,没有过五关斩六将方面的记载。

Qing dynasty lasted from 1600-1900.
This document is from which period?

Newton in 1660 invented calculus.

The equation as the girl examined it skip so many steps....suddenly you have x to power of x....then suddenly a few pages later talk about jntegration by parts


Calculus started with y=x*x differentiate to get 2*x.
as starting point to understand....and very simple you have to discover this first.

late Qing. This is a translation done by by qing scholars. Nothing inventive but i do give credit to making the effort during those times.

btw: Liebniz is the co inventor of calculus at around the same time.

Translations? It looks they took bits and pieces not very coherent

I think who makes best use of it is most important....not who thought of it first

The TW girl in the video is pretty smart to be able to interpret the symbols and equations.
