主题:国债负利率的日本,越借钱政府赚得越多,当然不怕花钱 -- forger
this is an another subject worth of tons of books, again, what we care about is its "core algorism", not really the "technical" details (which is "painfully" a core part of physics as well, so, we all have to be technical evils) of it, for the benefit of coding it out, potentially making a thinking model out of it, that is kind of why I heavily write in physics and math;

大脑所有的神经元细胞(1000亿以上), 1 细胞 =1000 Trillion atoms, the building parts of 细胞 such as DNA, RNA, protein, all have millions of atoms each.
so, basically 大脑= a group of atoms working together as a quantum system in terms of physics, with Numbers of atoms > out of current physics model's reach.
if I remember correctly, our current physics model can only handle wave function of a few hundreds of atoms working together as a system.
"本世纪初, 人们创立了量子力学理论, 用于研究微观粒子的运动规律。1927 年海特勒和伦
敦应用量子力学原理研究了两个氢原子组成氢分子的化学键本质, 从而开创了量子化学的先
河。就在量子力学诞生后的1929 年, 当时的剑桥大学数学教授Paul Dirac 声称, 把整个化学归
结成一些数学方程的基本定律已经完全搞清楚了, 唯一的问题是方程太复杂, 以至于不能解这
些方程。Dirac 是赫赫有名的量子力学创始人之一, 他与Schrdinger 共享1933 年物理学诺贝尔
奖。Dirac 所指的方程即是现在人们熟知的研究微观粒子的Dirac 定态方程。由他的这番话足
见求解这些方程的困难。颇有趣的是当时作为剑桥大学数学系研究生的Pople 教授今天却因
为他在发展量子化学计算方法方面的贡献而获得1998 年诺贝尔化学奖。Pople 发展的计算程
序正是用于解决象分子这样复杂的化学体系的薛定谔方程。量子化学的根本问题就是求解分
子体系的薛定谔方程。由此可见, Pople 教授对量子化学发展所做贡献的伟大意义。Pople 教授
早在60 年代就率先把计算机应用于量子化学中, 在半经验量子化学计算方法方面做出了重要
的贡献。这里有大家熟知的用于研究不饱和有机分子的电子光谱的PariseParrPople 方法。
这一被称为PPP 方法的发明人之一就是Pople 教授。但是, 在当时, Pople 教授也象当年的Di
rac 一样, 认为由于对计算能力要求很高, 解决非经验的量子化学计算方法, 即便象求解
Schrdinger 方程的HartreeFock 近似解也是很难达到的。
求解Schrdinger 方程的HartreeFock 方法通常是由两个步骤来完成。第一步是把分子轨
道用一套基函数来展开。根据Boys 的建议, 这些基函数可以选用以原子为中心的高斯型函
数。应该指出, 基函数展开方法使复杂的微分方程变成比较简单的矩阵方程, 而后者特别适
合用计算机进行求解。第二步, 也是最重要的一步, 是用积分方法计算体系的各部分能量, 包
括动能、电子与电子之间的排斥能以及电子之间的交换相关能等部分。对分子体系计算这些
积分的工作量随体系电子数N 的增加而以N
4 剧增, 使得对于含多个原子的比较复杂分子的
计算无法实现"

what is the point?
the point is our current chemistry/biology theory about "含多个原子的比较复杂分子" working together as "gene", "protein" system is still largely an experience based science with potentially many fallacies evils fooling around, whom we have no idea, kind of the way chairman X may not like china "mathematics" VP Li, for the same reason, nobody likes "unknown";
the physics layer of GMO is "unknown", period.
and because we don't have a 量子化学计算 model of gene, protein, or any GMO stuff etc=GMO has a huge volatility risk, either directions, or any directions;
but, who cares about that "physics" risk of GMO now? it is already in our mind and body, for good or bad, just swallow it, and good luck (:).

what is the heck of that 量子化学 stuff in relation to 大脑神经网络"量子效應 "? how can I make my brain get rid of the damned "markov chain" thing, so I can think outside of box and be smarter?
well, "量子效應 " is much more related to 自旋 of 電子, atoms, etc, than anything else, with dirac equation breaking the ice for his fellow human being in getting further into "量子效應 " world, and 自旋 is both local and global, as such we have gauge field theory and model, pioneered by prof 杨振宁;

"量子效應 "/自旋 as an non-linear "breaking through" quantum effect of both locally & globally through of connected human 大脑神经网络 is actually the trick of 列宁建党建军组织 model, and with that model, TG powered numerous 生的伟大 死的光荣 folks, it is essentially a 自旋/"量子效應 ", or 精神原子弹;

and in that AI platform, we can possible have our brain get rid of the damned "馬可夫鏈(Markov Chain) " and become much more productive, although we may have to pay goog etc some kind of fees.
again, I would hope that chairman X and his red gen II club buddies are not going to fight a yesterday's war of "生的伟大 死的光荣" in today's world, that would be a losing trade with potentially permanent damage to Chinese as a nation, period.
