主题：美国求学执教的见闻和感受（0） -- changshou

1. usa as a 寬譜 society sitting on top of the world

1)寬譜 to the extreme sometimes, in almost all areas,

to the point where "国内大概超弦方面也是几乎空白", 那真是好事，说明这种高级学术腐败还没有传到国内去", but it still exists & get developed in usa;

2)寬譜 to the point where usa can attract global intellectual talent/capital, TSLA's founder Elon Musk, google's founders, etc;

"风游精"

"中国在追赶不假，距离美国在缩短也不错，但要达到超越这个层次，可不是一个简单的线性外延。"

"【南京为亚青会开放测试Facebook等社交媒体】亚青会期间，来自各国的青少年将可在南京享受到畅通开放的网络环境。南京市长季建业说，“亚青会的运动员都喜欢搞自媒体，要确保网络安全、确保线路顺畅。”南京市委常委、秘书长刘以安介绍，已经对Facebook、Twitter等社交媒体进行了开放测试。(新华网)"

3. 层次超越=non linear, or it is not 层次超越

we can't always blame china political top 常委、秘书长 folks for blocking Chinese people from exchanging information with the rest of world, and many unbelievable or whatever with 中國特色;

as the 为什么汉语是世界上最先进的语言 author "冷酷的哲学"

said, the Chinese pride(culture etc) is in our blood ...and....and...argue/discuss 4 ever

by the way, I think most of "left wing" folks here in this forum are not 5 cents folks, they are all have some 世界上最先进的语言 or whatever in their mind, writing whatever out of their minds, honestly in a way, though a few are 5 cents for sure;

still, social science=basically whatever you can say, therefore full of noise, in a way.

4.so, I want to talk about us as an individual

I have posted quite bit under "为什么汉语是世界上最先进的语言", and your series about brain/AI

for any individual, how to grow? it is almost like 层次超越, non-linear, you have to jump out of the box/思想的牢笼 first, but how? it is almost impossible for most of us after passing certain age, and we all have about 30k days to try, then, over.

..........

somehow, I feel the next generation AI equipped with modern math/physics may be able to help those on the margin of 思想的牢笼 (not those still deeply trapped inside his/her 思想的牢笼), hand them a hand, and they will jump out of 思想的牢笼, and fly, be an outstanding/innovative/层次超越 leader in whatever he/she does, benefiting him/her and society

goog/tsla, combined with all other us resources may be moving in that direction, creating a new business model, leading the economy breaking out of its current overcapacity/low growth mode

5. Chinese mainland modern math/physics education

if nothing else, very few professors really know 流形, 相对论 (sr, gr), in 周光召's words, then how to teach students?

by the way, I do think that is to some extent related to "translation"/language issues, if you read classical English textbooks on 流形, 相对论 etc, it is not that hard as perceived/"marketed";

again, without mastering of the key concepts of 流形, 相对论 etc by a large population of a nations intellectual elite, how to do non-linear 层次超越?

and we have not talked about china political top recently made 宇宙真理 yet...

6. US side

import model? from Europe, china, india

somehow, us education evolves into a 精英 model by family/environment/chance, so if you are really talented or just motivated/hardworking, you are likely able to access that 精英 resource network, and like succeed as well;

otherwise, enjoy dating, sex, sports or whatever when in school, including many colleges; after that, be a good worker working in walmart/sax avenue fifth, and most importantly whether you have a paycheck or not, be a good consumer, go and get the most popular iphone, google class.

it may make sense: if you can't make it to steve jobs, then just enjoy his invention/iphone, why not? be a part of great American consumer economy, help testing innovations as a good consumer, and you are still happy

the Chinese culture/model, we all know already.

unless, china can replace USA as 吸引中心 of global intellectual talent/capital, there is no way china can lead the world in any cutting edge areas, whatever it may be, and for china to lead world it has to contribute something to the humanity civilization, what china has contributed so far?

still, with amazing rise of Chinese economic/political/military power of the most recent 20 years, US has started feeling pressure, and it would be interesting to see how US system of its pride can adapt in pre-college education area, educate and develop its own young population, as opposed to an complete import model, very challenging, if not impossible, 家家都有本難念的經, still, I would think that is not much worse than china political top's 宇宙真理 brain storming of young generations by folks like 南京市委常委、秘书长 folks.

7. "风游精"

"中国在追赶不假，距离美国在缩短也不错，但要达到超越这个层次，可不是一个简单的线性外延。"

超越层次=不是一个简单的线性外延, I like this part, thanks a lot.

this is basically a brain 譜分佈 issue;

三角形/勾股定理/毕达哥拉斯定理=空间中两点间的距离平方等于空间中所有完备正交分量平方和, conventional gauge theory;

gr: there is no a single/unified gauge model/三角形 applicable for a gr/广义相对论 world, 1 of reasons= 三角形 in a gr manifold is twisted, not conventional anymore;

however, locally in our brain we all have a conventional 三角形 based gauge model, but as we know once we move out of "local" and move into a gr world, we run into problems, our 三角形 is missing some dimensions/自由度, our brain 譜分佈 does not recognize the signals based on those dimensions/自由度 which is not in our original 三角形 gauge model;

and because of whatever reasons, we can not update (or fast enough) our brain 譜分佈 as we move into a new "local" (new job/relationship, challenge, etc), we are basically 睁眼瞎, tumble, and we don't know how to interact with surrounding people who have a different 脑譜分佈/三角形 gauge model,and we run into conflicts with them,etc, and consequently we have 脑内热力学上火 problems, making things even worse, we are basically burning energy for nothing except for the increased entropy in our brain, further downgrading its modeling ability, etc.

this is a very interesting topic.
