Advanced course == course in advance

Posted on by

philip1209 on June 30, 2018

One of my favorite classes in college was a physics course taught in this way:

1. Before class, we were assigned to read a chapter from the textbook, understand the material, and complete two or three homework problems from the material we had just self-learned.

2. After submitting homework, lectures focused on discussing the concepts more in-depth. Everybody already had a baseline knowledge, so the professor would highlight the important takeaways, applications, live demonstrations of concepts, etc. I found these lectures engaging because I had already learned the material – and the lectures focused on mastering it.

3. Sometimes there would be follow-up homework problems focusing on advanced applications or derivations. These advanced problems were closest to exam questions.

Some takeaways for me:

  • If we didn’t have homework to do before class, I doubt I would have consistently learned the material before lecture.

  • Lectures taught us more than the “what” – it taught us the “why” and how these concepts related to other areas.

  • Lectures focused on answering questions, exploring curiosities (like “what if” questions), demonstrations/experiments, and mastery. The professor added value beyond the written material!

I hope this helps OP because it sounds like they have material prepared beforehand, which means that the lectures could go beyond the material.

Lectures On Computation

Posted on by

Feynman’s philosophy of learning and discovery comes through strongly in these lectures. He constantly points out the benefits of play around with concepts and working out solutions to problems on your own before looking at the back for the answers. As Feynman says in the lectures: “If you keep proving stuff that others have done, getting confidence, increasing the complexities of your solutions — for fun of it — then one day you’ll turn around and discovered that nobody actually did that one! And that’s the way, to become a computer scientist.” Imagine that you are explaining your ideas to your former smart but ignorant, self, at the beginning of your studies!

Do not ask your children to strive for extraordinary lives. Such striving may seem admirable, but it is the way of foolishness. Help them instead to find the wonder and the marvel of an ordinary life. Show them the joy of tasting tomatoes, apples and pears. Show them how to cry when pets and people die. Show them the infinite pleasure in the touch of a hand. And make the ordinary come alive for them. The extraordinary will take care of itself.

The ultimate self-fulfilling prophecies:

1. free will or not

2. god or no god

3. afterlife or not

4. future spouse exists or not

.

Why self-fulfilling?

4. you have another half or not

.

If you act as if your future wife exists, you have a much higher chance of finding her, because you have actually been providing the environment for her to exist.

If you act as if your future wife exists, compared with assuming not having one, you live completely differently. You will make yourself financially stable; you will earn and save money for your future wife and children. You will make yourself healthy so that you can live long enough to finally find her; and then stay with her for decades. You will make and meet genuine friends, for you know that one of them is either your future wife or the one who introduces her to you.

If you know that your future wife exists, you will not have any romantic relationship with anyone that is certainly not your future wife, no matter how beautiful she is. Actually, you will not start any romantic relationship with anyone at all, unless she is potentially your future wife.

You will keep writing letters, sending them to the future; to your future wife. Once your future wife realizes that those letters may be actually for her, she will find you to confirm.

If you act as if your future wife exists, you know that the goal is not to find the “best” lady, but to find your future wife.

Your wife is the key to the lock of your life. Your goal is not to find the “best” key in the world, but to find the key of your life.

It is not to find the “best” key, but to find your key.

The Buddha attacked all attempts to conceive of a fixed self, while stating that holding the view “I have no self” is also mistaken. This is an example of the middle way charted by the Buddha.

The ultimate self-fulfilling prophecies:

1. free will or not

2. god or no god

3. afterlife or not

4. future spouse exists or not

.

Why self-fulfilling?

3. afterlife or not

.

Whether “afterlife” exists or not depends on your definitions of “self” and “afterlife”.

.

At one extreme, the definition of “afterlife exists” is that, after death, the same fixed self will continue to exist; “you” will exist in exactly the same way as before. In this definition, afterlife does not exist.

Note that even before death, during your normal lifetime, there is actually no “same fixed self”, “you” keeps changing every day and every second.

.

At the opposite extreme, the definition of “afterlife exists” is that, some aspects of you continue to exist in some way. In this definition, afterlife exists.

For example, if some of your writings still exist after your death, they will preserve some of your mind.

.

This question is like, when your old computer is dead and has got replaced, does it still exist?

The old computer hardware does not exist anymore. However, some of the software and the data do. But just some, not all.

.

Continue to exist?

All of you?

NO

Some of you?

YES

He attributes his lifelong habit of writing every day to an incident in 1932 when a carnival entertainer, Mr. Electrico, touched him on the nose with an electrified sword, made his hair stand on end, and shouted, “Live forever!” It was from then that Bradbury wanted to live forever and decided his career as an author in order to do what he was told: live forever.

The ultimate self-fulfilling prophecies:

1. free will or not

2. god or no god

3. afterlife or not

4. future spouse exists or not

.

Why self-fulfilling?

2. god or no god

.

Whether “god” exists or not depends on your definition of the word “god”.

.

In some definitions, god does not exist, because of the definitions’ self-contradictory nature. For example, god is good but he wants you to suffer for no reason.

.

In some definitions, god is possible to exist. For example, a god is any being that has a higher level of consciousness than a human being.

We can say that a human being’s consciousness is higher than a dog’s, in the sense that a human can understand things that a dog cannot. For example, most dogs do not understand what a computer is.

Similarly, a dog’s consciousness is higher than an ant’s. An ant’s consciousness is higher than a tree’s. A tree’s consciousness is higher than a rock’s.

In the opposite direction, it is highly possible that in this universe, there are beings that have a higher level of consciousness than human beings. It is highly unlikely that human beings are the highest beings.

Even within the human being species itself, different people can have different levels of consciousness. Even within a single person’s lifetime, one can be at different levels at different ages.

.

In some definitions, god can exist. You become that god.

In those cases, whether god exists or not depends on whether YOU are willing to become that god, taking up his responsibilities.

To realize is to realize, 1.2.2

So in theory, there is no free will, because the future is already fixed, by the physical laws.

.

However, even if we knew the exact physical laws, it would be still logically impossible to get all the data of the present state of the whole universe, because it is logically impossible for any observer to observe itself, with 100% details, directly. For example, no camera can take a picture of itself directly.

So “in practice”, which is actually also “in principle”, there is free will, because logically, no one can predict, with 100% accuracy, your future actions.

.

In one logical sense, the future is already fixed, so there is no free will. In another logical sense, the future is fixed, but no observer can know that “fixed future” with 100% accuracy, so there is free will.

As a result, whether you label your actions are due to “free-will” or “not-free-will” has no real consequence. In other words, whether there is free will or not has no meaningful difference.

The difference that makes no difference makes no difference.

So you can actually transcend the free will problem altogether. You can just ignore it and live your life.

Or, you can somehow capitalize on this freedom of labelling your (future) life as either fixed or free, depending which label is more beneficial for you in a particular situation.

For example, when you are highly under pressure, you know that everything is fixed by the physical laws, from god’s point of view. When you are highly above pressure, you know that you are partially responsible for creating your own reality, because the future is not fixed for any one observer, for there is no “god’s point of view”.

You have the flexibility to label it in one way or another.

In other words, when you realize that you should be a polite person, that polite person is realized at that moment.

二百萬 3 | 如此仙子 1.5 | 鐵達尼極限 2.7 | 尋覓 1.10 | 已婚單身 1.6 | Singles 1.6

這段改編自 2010 年 10 月 14 日的對話。

.

然後，我們回到「你倆其中一方，要去外國升學」的問題。這個如果發生在我身上，我不會覺得是問題；因為，如果是外星人的愛情，就不太需要一定在一起。反而，我最重視的是，關注對方的短期生活，過得快不快樂；和長期人生，過得有沒有意義。

如果你的「愛情」是純粹為了，追求「愛情的感覺」的話，那你所謂的愛情，就是只是自私的愛情。如果只是自私的愛情，即使不是一方外地升學，即使在一起，也不會維持得到。

所以，如果是真正長久愛情的話，就不會是自私的。真正永久愛情，就是「不需要愛情的愛情」，就是「不需要愛情感覺的愛情」。愛情的核心，並不是感覺，而是兩個心靈的獨有關係。

始於外在條件，而成於形上。

亦即是話，如果我的另一半，有大理想要追求的話，我一定會支持，甚至一同去追求。即使要的分隔（例如）四年，我也不會太介意。（如果是永久的分隔，則是另一個話題，暫且不談。）

那如何維繫感情呢？

首先，你要知道，何謂「感情」。

.

「感情」者，「感受相同情境」也。

動物間，所能感受的相同情境，可能只有物理世界，即是日常生活。而精靈仙子間，所能感受和創造的相同情境，則不只有物理世界，亦不限於日常生活。只要你倆在分隔期間，持續有超時空搞作，感情方能維持，甚至加深。

例如，你倆可以共同研究，留學那科的學術題目。

又例如，你倆可以共同編寫一個網誌。

再例如，你倆共同經營一個網站。

.

最好的共同情境，就是共同創作。「共同創作」就是，共同創造一個，嶄新的世界。

機遇創生論 1.3

Posted on by

這段改編自 2010 年 4 月 18 日的對話。

.

你可以花一生的時間，去令到自己受歡迎；但是，你的喪禮將會有多少人出席，還要視乎當日的天氣。

.

萬事俱備，只欠東風時，就應該立刻離開，讓東風做事，不要阻礙東風。

亦即是話，一件事情的發展結果，受眾多因素影響。有些你控制得到，有些你控制不到。你既要盡力處理，你控制得到的部分，亦同時要盡力去忽略，你控制不到的部分。

千萬不要干涉，大自然的內政，因為，那只會弄巧反拙。

例如，如果你想受人歡迎，你可以做的，就是認真工作，善待自已，以誠待人等。最終會不會受歡迎，那不在你控制範圍。

試想想，如果你企圖保證，自己受歡迎的話，情形會怎樣？

情形就是，你會不斷地提醒他人，你自己的存在。那只會為他人，帶來極大的滋擾。那反而會令你討厭。

原理上，你就應該化成磁鐵，盡其在我地，增加自身的吸引力。重點是，你只可以吸引，而不能拉扯。

正如磁鐵一樣，它只能吸引磁性物質。其他東西，並不會受其吸引。

題外話：而更重要的問題是，為什麼要追求「受歡迎」呢？「受歡迎」的好處，真的大於壞處嗎？

而「不要干涉大自然的內政」，並不代表，「種子論」是「被動」、「消極」的。或者說，那是有意義的「被動」和有策略的「消極」。

那並不是負面意思下的被動消極，原因是「種子論」的行動三部曲，其實也相當上進積極。

第一部，要盡你自己的能力，獲取最多的情報，有關哪裡的土壤，最有機會讓農作物茁壯成長。然後，在那些範圍播種。沒有種子，就不可能有果實。　

第二部，有種子，亦不一定會果實。所以，你要積極不做事，積極去等待。除了定期的灌溉和施肥等工序外，並沒有任何行動，令你可以保證某單一棵植物，一定開花結果。

第三部，而要訓練到自已，習慣在適當的地方和時間，去「積極不做事，積極去等待」的技巧是，先做其他東西，同時在其他土壤播種。

而這正正回應了第一部：正正是因為，在某一指定地方有成果的機會極細，你要在最多的土壤，灑下最多的機遇種子；而底線是，不要多到自己管理不到。

.

一件事情的發展結果，受眾多因素影響。有些你控制得到，有些你控制不到。你既要盡力處理，你控制得到的部分，亦同時要盡力去忽略，你控制不到的部分。

While we are free to choose our actions, we are not free to choose the consequences of those actions. Consequences are governed by natural law.

— The 7 Habits of Highly Effective People

— Stephen R. Covey

那只是理論比喻。執行「種子論」的真正難度在於，有時，在事情完結前，很難去分清該事件中的哪些部分，是「可控部分」，而哪些部分，卻是「不可控部分」。

亦即是話，「謀事在人，成事在天」之中，哪些部分而要由「你」去「謀」，而哪些地方是由「天」去「成」，事前不一定知道。

所以，那不會有公式答案，只能靠自己或他人的學術知識和實際經驗。

Grant me the serenity to accept the things I cannot change,

the courage to change the things I can change,

and the wisdom to distinguish the two.

「經驗」的近義詞，是「錯誤」。它們不同義的地方，在於「經驗」可以累積，「錯誤」不一定可以累積。

「種子論」的重點，並不是給予你，一條必勝的方程式。

「種子論」的重點是，令你知道，無論如何，你也會遇到無數次的失敗；那是正常不過的事。「種子論」的重點是，令你不再害怕失敗，從而，你會勇於嘗試，敢於超大量地犯錯。

「種子論」的重點是，重複犯同一個錯誤本身，並不能提高成功的機會率。

「種子論」所要求的「不斷犯錯」是，每次也是「新的錯誤」。「新錯誤」的意思，並不只是相對於你來說是「新」，而是相對全人類來說，都是「新」。

別人犯過的錯誤，你也不可以再犯。

一千萬次的失敗，可以兌換一次的成功。

而一次的成功，卻可以兌換一千萬次的應用。
