家园 自然语言: 熱輻射, 腦殘 risk

1.

this is a good book, thanks, and I will read it.

"From Pythagoras's harmonic sequence to Einstein's theory of relativity, geometric models of position, proximity, ratio, and the underlying properties of physical space have provided us with powerful ideas and accurate scientific tools. Currently, similar geometric models are being applied to another type of space—the conceptual space of information and meaning, where the contributions of Pythagoras and Einstein are a part of the landscape itself. The rich geometry of conceptual space can be glimpsed, for instance, in internet documents: while the documents themselves define a structure of visual layouts and point-to-point links, search engines create an additional structure by matching keywords to nearby documents in a spatial arrangement of content. What the Geometry of Meaning provides is a much-needed exploration of computational techniques to represent meaning and of the conceptual spaces on which these representations are founded."

2.

remember "Erik Verlinde"? we talked about him and that young Harvard physics guy's AI app based on Verlinde model.

roughly speaking with a lot of analogies, 引力 is interaction force, but it is very hard to measure or quantize 引力 or 引力量子化 in more physics oriented terminology. 引力质量和惯性质量相等, locally, you can't tell the difference between the two.

3.

what all these have to do with my brain?

as posted, human brain out of its survival and growth instinct in interacting with unknown heat bath("阶级斗争"強耦合 field) surrounding him, quantum brain has to perform this Feynman路径积分, again, this is the only model humanity understands in terms of QFT;

now, 引力质量和惯性质量相等 (an analogy, QFT excluding GR), locally, and I am locally all the time (vs us wall street and Chinese TG kind of organized global view/modeling), how my brain can do its job? it can't, then we get emotional, our expectations get hit by hard reality, broken brain, broken heart, omg, end of world, or a stone brain from here into a grave, as chairman mao said, he is a smart guy, he sees most people around him (such as vice chairman Liu(:))with actually stone brain.

4.

Erik Verlinde's 引力的熵力假说

4.1

why "阶级斗争"? why not united under chairman mao and we together fight heat bath (unknown challenges facing humanity in an analogy, such as what the heck is going on with 牛顿的水桶, which humanity still can't figure it out yet), then we all go into communist heaven world?

there is no chairman mao anymore, first of all;

secondly, humanity has come to some kind of consensus (more outside of china, and china is slowly catching up with white in terms of "logic gap") that we have to perform a civilized "阶级斗争" peacefully among ourselves in modeling this heat bath challenge, etc.

kind of like 牛顿的水桶:

水桶 is 轉動, but relative to what? relative to heat bath? then how to measure & model heat bath?

one way is to measure 水桶轉動 itself, and hopefully, we can derive 引力/heatbath via derivatives (2nd order modeling etc) of 水桶轉動

similarly

civilized "阶级斗争" peacefully among ourselves 逻辑实证證偽=basically the whites market system and 人權

政黨競爭,etc, a messy (in terms of its productivity and etc) 公知 model, vs china's 伟光正 model.

basically, it is a 牛顿水桶轉動 "game" in a social science setting, shall we as a humanity pick some 伟光正 group an judge of this entire humanity game of survival and growth?

that said, TG's model(no choice anyway) is likely to work out in china's gdp growth oriented economy, since it is basically 山寨 white from behind in almost every major area of its economy, a much easier challenge to handle.

in terms of Erik Verlinde's 引力的熵力假说, we have to come back to our 熱力熵力 model to gauge 引力 or new information.

4.2

the bloody cost of 熱輻射

in an analogy, human brain "神经元弹簧" struggles like a snake in this social 引力 field, for his or her survival and growth, as an individual (mostly unorganized, even in china, if you are not part of TG-centered elite, which is always a tiny minority), then most likely your "神经元弹簧" will be losing its battle vs heatbath 熱輻射, eventually stop working, giving up, go to a temple and work on 氣功 stuff;

and biologically, most people die this way anyway, in their short life on earth.

5.

without going into specifics of physics terms and models, what we can learn from Erik Verlinde's 引力的熵力假说 is actually very basic but very important, often very alarming:

自然语言: 熱輻射, 腦殘 risk, if not modelled well, and heat 传播 is super fast, soft 自然语言 can 爆 your ass (if lucky) and brain (very bad,omg), all legal to the profit collectors or market makers.

and in TG's terms, 利用小说进行反党 是一大发明 鄭大你的眼睛, plain vanilla "logic", but often in a very twisted Chinese local settings, much more twisted than us wall street market place.

Erik Verlinde's 引力的熵力假说 is still a 假说, meaning it is only a 逻辑 model, there is no 实证 yet;

with that comes big smiling faces of us wall street, and Chinese TG: 利用小说进行反党 是一大发明 as a business still commands a fat profit margin, long way to go, just do it, why not? (:)

6.

with all that and in the "final" analysis, humanity as a system has to come back to its roots in

"科学 = 逻辑 + 实证"

http://www.ccthere.com/alist/3986059

科学 = 逻辑 + 实证 [ Solitude ]

前者主要指分析(演绎)逻辑,也就是假设,推理,结论,blabla...这个东西主要起源于古希腊的苏格拉底,柏拉图,亚里士多德,最早最有名的产品就是欧几里德的几何原本了。欧几里德本人就是柏拉图学园的学生。后者我想还是要感谢伽利略的启蒙吧,就不多说了。

科学当然也需要归纳逻辑(白米,黑米,红米都能吃,所以所有的米都能吃)的帮助。其实任何人都离不开归纳逻辑,否则会饿死的(罗素语)。但是依赖归纳逻辑的科学是不严谨的,最终还是要靠分析逻辑"

"歸納法是採用「由部分累積到整全」的研究途徑,而演繹法則是「由已知部分透過邏輯推知未知部分」的研究途徑"

again, can humanity afford going away from that model, in physical science in particular, in humanity and society in general?

there is no alternative yet.

7.

the beautify of Feynman 路徑積分 again

"经典的状态其实对应的是量子态空间的一组基, 量子事件通常被说成是在这些点处插入顶点算子,这些顶点算子诱导了量子场的激发和退激,物理上要考虑这些量子事件的关联,也就是说这些事件背后有没有什么物理的或者动力学的原因"

again, in an analogy, 顶点算子 in a dissipative system (耗散系统, physics can't handle that yet) could be even more dramatic in terms of its impact on the system itself, think about 愛因斯坦 and 希特勒 as some kind of 量子事件/顶点算子 on the border of an otherwise fairly classical human system;

and I would think that humanity system now is solid enough to prevent 希特勒 kind of 顶点算子 to come to power and to change the path of humanity as a whole;

but, we don't really have a system to produce 愛因斯坦 type 顶点算子 yet;

this is kind of physics of white's 天賦人權 model: other than humanity reasons, there may be physics reason as well: we expect your child to out perform in whatever field fitting him/her, let her fly and shine, it will benefit all of us, eventually, including your small Chinese family organization.

we hope him or her to be an 愛因斯坦 type 顶点算子 to help humanity move forward.

that is why I said a couple of times here. if possible, let your children start studying English and quantum physics, starting yesterday, better in US or Europe, period, get it, baby?(:)

很多人可能都听过这个故事:牛顿在苹果树下正在聚精会神的思考,突然一个苹果砸到他头上,他茅塞顿开,发现了引力。但是长期以来,物理学家也知道引力很奇怪,和其它基本相互作用力相比,引力处理起来非常困难。现在原因可能已经找到:引力不是一种基本相互作用力,而是一种类似橡皮的弹力一样的衍生力。

据纽约时报2010年7月12日报导,阿姆斯特丹大学理论物理学院埃里克.弗林德教授(Erik Verlinde)提出引力新理论,认为引力不过是物理学中热力学定律的必然结果。

弗林德教授这样阐明自己的观点时说:“对我来说,引力不存在。”这并不是说他不会跌倒,但弗林德博士和其他一些物理学家认为,科学一直在以错误的方式看待引力。有一些更基本的规律导致了引力的出现,就像股市规律是一个个投资者行为的集体表现,或者弹力产生于大量原子的力学行为。

理论的核心和系统无序程度——熵有关。就象人的头发在湿热的环境下会卷曲,因为头发卷曲比伸直有更多的组态,而自然喜欢更多的选择。要想把头发拉直从而消除卷曲,需要力。忘掉弯曲的空间或牛顿引力,我们称之为引力的力量只不过是一种自然倾向——无序最大化的副产品。

弗林德教授的理论认为引力从本质上是一种熵力,如果一个物体在其它物体周围发生微小移动会改变周围的无序度,就会感受到引力。在这个想法的基础上加上全息理论的假设,他可以推导出力学中的牛顿第二定律。另外他的理论对物理中的惯性质量也有了新的认识。

弗林德教授的理论在物理学家中激起了强烈的反响。哈佛大学弦论学家安德鲁.斯特罗明格(Andrew Strominger)说:“有些人说这不可能是正确的,其他人则认为这是对的,我们已经知道它---它正确而深刻,正确而平凡。”“你不得不承认,”他接着说,“它启发了很多有趣的讨论。这是一个很有趣的想法集合,它点到了宇宙中我们最不了解的事情。这就是为什么我喜欢它。”

弗林德教授说在纽约石溪大学访问时,有人跟他说围绕着引力展开的故事就象皇帝的新衣一样。“我们知道引力不存在已经很长时间了,”弗林德博士说,“现在是到了大声喊出来的时候了。”

现代科学对宇宙的研究基本上是以现在的引力理论为基础。如果引力不存在,那么目前科学对星系、宇宙结构的认识必然是错误的,这可能是天文学家常常发现引力难以解释遥远天体的运动而不得不引入“暗物质”的原因。新的引力理论或许会激发科学家们寻求对宇宙全新的认识。
