The World as Will and Representation

… Schopenhauer notes importantly that our body — which is just one among the many objects in the world — is given to us in two different ways: we perceive our body as a physical object among other physical objects, subject to the natural laws that govern the movements of all physical objects, and we are aware of our body through our immediate awareness, as we each consciously inhabit our body, intentionally move it, and feel directly our pleasures, pains, and emotional states. We can objectively perceive our hand as an external object, as a surgeon might perceive it during a medical operation, and we can also be subjectively aware of our hand as something we inhabit, as something we willfully move, and of which we can feel its inner muscular workings.

From this observation, Schopenhauer asserts that among all the objects in the universe, there is only one object, relative to each of us — namely, our physical body — that is given in two entirely different ways. It is given as representation (i.e., objectively; externally) and as Will (i.e., subjectively; internally).

Past papers 26.5

這段改編自 2010 年 6 月 15 日的對話。

製作「魔法筆記」時,記住用一本完整的筆記簿。練習 past paper(歷屆試題)時,亦都要那樣。唯一的分別是,past paper 的練習簿,每科也要用很多本。

千萬不要用草稿紙來做 past paper,因為那樣的話,就會有神奇的事情發生。我的經驗是,只要我把練習做在個別的紙張上,第二日就會立刻找不到。

EPR paradox, 9

In an EPR experiment, once you have measured one particle’s spin, you know the spin of the opposite particle instantaneously.

Your ability of getting the total information at once is due to the fact that you know partial information in advance. Since the time of the separation of the two particles, you have already known that “the opposite particle must have an opposite spin”. 

Let

A = the spin of your particle

B = the fact that the opposite particle must have an opposite spin

C = the spin of the opposite particle

knowing A + knowing B = knowing C

There are no superluminal (faster-than-light) communications between the two particles. So the whole EPR experiment is compatible with classical locality, aka special relativity.

The strange thing is the quantum non-locality part.
