家园 "现在的电脑做不到的:, gd intuition

"再讲一次,人脑比现有的电脑要具备高明很多的鲁棒性,那就是说,扰动很难产生实质性的信息处理上的区别。这是现在的电脑做不到的。但是,不管怎么鲁棒,还是存在一个小扰动就产生天上地下的差别的时刻和地方"

1. very good intuition, I like that.

but to get further excited, you have to love theoretical physics they way you love "有花戴的人家的闺女", 闺女 here copied from "聊天大厅 自动刷新 可完整聊"

2. "扰动很难产生实质性的信息处理上的区别。这是现在的电脑做不到的"

because in most case of today's world, we are dealing with a world of "non sr macro with very little qm if any", so basically, a conventional heat equation takes care of everything, and it can perform heat equation opertions almost at light speed, and "put down" everybody else into the Gauss-Markov Heat Bath, "heatmblow up" their brain on their way into the heat bath, and they could never understand before and after their heat bath, "how come?"

3. for any meaningful further discussion on this subject, you have to get some

"有花戴的人家的闺女" come to the party, and the girl better to have some kind of theoretical physics brain, or we can't even get party started

wiki:

For most of the last century, it was recognized that Fourier equation (and its more general Fick's law of diffusion) is in contradiction with the theory of relativity,[5] for at least one reason: it admits infinite speed of propagation of heat signals within the continuum field. For example, consider a pulse of heat at the origin; then according to Fourier equation, it is felt (i.e. temperature changes) at infinity, instantaneously. The speed of information propagation is faster than the speed of light in vacuum, which is physically inadmissible within the framework of relativity.
