家园 "世界是二维的?关于全息屏和作为熵力的引力"

I really like this paper, smarty folks, as I said, thought invoking, and how come we Chinese is always behind and play 華車, 璀喇叭胎教子, writing reviews and follow up papers, as 李淼 said, not sure if 李淼 still even read journals anymore

1.

爱因斯坦场=gravity, 幾何的, what you can do with 幾何?

2.

热力学: 熵, temperature are all defined and measured by partition function and stat @macroscopic

level, are you a sys admin guy with a daily updated password?

none of the above, just a plain individual, then

熵@micrscopic state level=0,may be that is why we always feel good and pride, in our blood, and most likely it is 幻覺, fake, baby;

penrose has been trying to get a more meaningful 熵@microscopic, going no where;

3.

Verlinde, after his string theory (can never be tested/measured at current energy capability level) went no where, combined the part 1&2

so, now with verlinde's theory, we have some kind of 热力学引力場 model with entropy 动力学 between macroscopic and microscopic with that paper as a start, to get into social

引力場 动力学, as an appetizer, kind of, before a really good dinner, white's near term dream

4. why doing all these?

US 4政委 parallel 制度 can never compete with tg's 1 政委 hierarchy structure (result of that is 愚民, very likely) , in terms of social

引力場 information collection and analysis, and tg's 经典物理 power in its top-down 1 政委 hierarchy structure , is unmatched globally.

so, white has to go social/market powered AI for social 引力場 , etc, so US 4政委 parallel could work together with market and half 愚民 democracy, to compete with tg's 集权制度, to 改良 social 引力場 測度, 改良生產關係, etc

5. as a personal mental health advice for all of us:

unless you have tg's minister level 组织文件 or US 4政委's expensive AI model, basically all the information we collect and analyze as an individual @microscopic, are very close to garbage in terms of 機率 density distribution function , but most of the time (it should really be the opposite, upside down kind of mess up) we all feel we see and feel something great, because the system wants us all to do that and feel that way and try our best@microscopic, so system can 費曼 路徑積分 @system and macroscopic level, to come out with a collective level AI, and in the process, any individual ant can be sacrificed with no mercy at all, basically

and very often, for an individual ant, garbage in =garbage out@紅外, and once 紅外=4 ever紅外

Verlinde,

《宇宙的琴弦》读后感

sky.hhu.edu.cn/ec.../read-interactive.do?... - 轉為繁體網頁

最近有个搞超弦理论出身的荷兰物理学家Erik Verlinde放弃了超炫理论,另辟蹊径,提出万有引力不是基本作用力,就像皮球内部的压力,只是封闭气体分子的集体 ...

世界是二维的?关于全息屏和作为熵力的引力

Verlinde关于引力起源于熵的论文.先要注意的是论文的逻辑链,作者本人就很重视这一点。论文的逻辑起点在全息屏上。假设我们手头上有全息屏上的有时间变量的微观态物理,而且这些定律是时移不变的,那么就有能量守恒了。而且微观态数不是一,那么我们就有了时间、能量、微观态数作为以下理论的起始点,微观的物理是怎样的现在先不关心。总之靠现有的概念在宏观上就有热力学第一定律。因为宏观上可以有温度、熵这样的emergence(这个词译法好多,不知选哪个)的概念。好,现在还没谈及空间,在这里空间也是emergent出来的,在微观上是没有定义好的。不过这里只是一维是emergence的,另外两维被全息屏所占。好,现在类比下理想气体。理想气体的体积在微观里没有很好的定义对不对?而且有个热力学对偶量压强,那么就可以写下热力学第一定律的方程。类似地,全息屏emergent出一维空间x之后,其热力学对偶量就是力,引力。

刚才有了热力学第一定律的方程,现在假设一质量为m的粒子在emergent出来的方向上做个小位移穿过全息屏,屏上的熵变有个熵变的值(公式不打了,只看看逻辑链就算了)。现在有两个公式,再加上安鲁效应,就是温度与加速度正比那个,就可以神奇地把光速,万有引力常数和普朗克常数
