這段改編自 2010 年 3 月 27 日的對話。

正如，你上次問我，如果你有一個缺點是，每逢走近麵包店，就會瘋狂地購買過多麵包的話，你應該怎麼辦，才能去除這個缺點。我的答覆是，不要走近麵包店。那樣，你就從來也不會遇到「瘋狂購買麵包」這隻怪獸。你就從來也毋須去處理牠。

你想一想的話，就會發現，這個根本是一個邏輯定律。如果你在走近麵包店之前，都說服不到自己，不要走近麵包店的話，你走近了麵包店時，就更加說服不到自己，不要購買過多的麵包。

有很多惡習的成因，都是基於這個邏輯結構，例如吸煙。吸煙成癮的主因是，吸煙者以為自己，有一個凌駕於自然定律的自由意志：「我吸一點煙不會有什麼事。而且我可以隨時不吸。」問題是，這個是一個邏輯問題。如果你在從來沒有吸煙之時，都說服不到自己，不要吸第一支煙的話，你在吸了第一支煙後，你又怎會說服到自己，不要吸第二支煙呢？

相反，如果知道自己和萬物蒼生一樣，同樣受制於自然定律的話，你就會了解到，即使自己誓神劈願，戒煙同樣會異常困難。那樣，你就從來也不肯吸第一口煙。

「戒煙」的最好方法是，從來不要吸煙。

地球人往往以為，自己有一個凌駕於自然定律的自由意志，其實沒有。人（或者宇宙中的任何東西）只有受制於自然定律的自由意志。或者說，自由意志建基於自然定律。

想要在這個宇宙間呼風喚雨，就要極度詳細地，掌握各種自然定律，從而善加利用。讀理科有助瞭解「物理定律」；讀文科則有助瞭解「人情定律」。兩門定律缺一不可。

真相客觀程式 3.3

這段改編自 2010 年 3 月 27 日的對話。

（安：絕大部分人也不會研究「自己科學」。他們也不會以「自己」為「科學」研究的對象。換句話說，平常人對自己不夠客觀。他們會覺得自己有「自由意志」，例如「我要早上六時起床，就自然可以六時起到床。」

實情則不是那麼簡單。能否在六時正成功起床，除了意願外，還取決於你在之前一晚何時開始睡、身體狀態的好壞 和 當時起床後需不需要上班 等等。）

無錯。大部分人以為，物件和動物需要遵守自然定律，而人，尤其是自己，則可以任意違反自然定律，而毋須承受任何報應惡果。他們忘記了，自己也是人，人也是動物，動物也是物件，同樣受物理定律、化學定律 和 生物定律 的主宰。

例如，想六時起床，就必須設定好「六時起床」的所有先決條件：要保持身體健康，即是不要在平日累積太多的疲勞、之前一晚要早一點睡 和 調校好鬧鐘 等等。又例如，要別人信任你，你就要在長年累月地保持誠信。

所以，所有人都應該受科學的訓練。科學教育的最重點，不在於培養未來的科學家，而在於潛移默化，使大部分未來人，也知道這個世界有「自然定律」，從而習慣事事「以自然定律為中心」。

Information lost, 3.2

Posted on by

Information conservation

There is another very subtle law of physics that may be even more fundamental than energy conservation.

It’s sometimes called reversibility, but let’s just call it information conservation.

Information conservation implies that if you know the present with perfect precision, you can predict the future for all time.

But that’s only half of it. It also says that if you know the present, you can be absolutely sure of the past. It goes in both directions.

藉口 2

「理由」是一個「決定」。

「原因」並不是一個「決定」。

「理由」是一個「決定」。「理由」是權衡輕重時，支持一個「決定」的一些考慮元素。由於是內在的主觀判斷，「理由」有所謂「充不充分」。一個「決定」沒有充分的「理由」，就為之「不合理」。

「原因」不是一個「決定」。「原因」和「結果」，只是客觀描述事件發生的時間先後次序。由於是外在的客觀事實，「原因」沒有所謂「合不合理」。

Block spacetime, 5

This position has lead him to face the following problem: if time is not part of the fundamental theory of the world, then how does time emerge? In 1993, in collaboration with Alain Connes, Rovelli has proposed a solution to this problem called the thermal time hypothesis. According to this hypothesis, time emerges only in a thermodynamic or statistical context. If this is correct, the flow of time is an illusion, one deriving from the incompleteness of knowledge.

Single-world interpretation, 6.5

Posted on by

If this is the case, then wave function is deterministic. There is no free will. The free will is due to the ongoing superposition of eigenstates. Locally, we see superposition of “a and b” collapse to (such as) a. Globally, we also see b “goes to” the environment. Nothing is lost in a sense that no information is lost.

Then what happens when you make a choice by collapsing a wave function?

Free will, like wave function collapse, is a local illusion.

Since information cannot be lost, we always exist.

Single-world interpretation, 6.2

In the Many-worlds interpretation (MWI), when we say that “a + b” collapses to “a”, there is a shift of definition of “you”.

MWI is in one sense correct: choice b version of you still exists. But the trick is that he is not in another universe. He is in the environment of this universe.

And perhaps in reverse, you are also part of the environment of him.

Wave function collapse is a process of losing the superposition information to the environment.

The unchosen choices are lost to the environment.

Onion self 3.2 | 洋蔥自我 3.2 | Inner and outer, 3 |

Planck scale 3 | Hidden variable, 2 | T-duality, 3

If the quantum jump is an illusion or an approximation to the reality of events at a quantum level, then maybe events at the quantum level are actually deterministic and we could, in principle, determine the outcome of a quantum measurement. This all boils down to what is happening in the quantum “foam” at the smallest Planck Scale.

– Andrew Thomas, 19th March 2007

[guess] Then the hidden variable is related to the universal wave function and the planck-scale physics.

[guess] The universal wave function is related to the planck-scale physics.
