奇幻衝擊波 2.2 | 蜘蛛絲 5
人先天是極有創意的。你試試觀察一個小孩如何玩玩具就知道。一個人只要肯花一點心思，就可以炮製出超凡的意念，去改善到自己和別人的生活。
而且，有時，即使是一個簡單的意念，只要執行得透徹，都可以有鉅大的發展。例如：可樂公司的產品，主要是可樂。而可樂所建基的，只是一個意念：可樂秘方。

Physicist
You should be self-employed.
1. If some experience cannot be learned through self-employing work, work for others for several years first. (I had worked as a teacher for 3 years.)
2. For being a physicist, you have to join a university first, as a postgraduate student or a researcher. I did it by being a master student. And I have applied for UU.
The main point is your teacher and your boss have to be much more intelligent and experienced than you. Otherwise, you cannot learn much.
Start a small business.

天堂力量
這段改篇自 2010 年 4 月 8 日的對話。
我年輕時有極嚴重的情緒病。「唯有經過地獄的磨難，才有創造天堂的力量。」（改篇自尼采）那我有什麼「創造天堂的力量」呢？
我可以幫人解決心理問題。很多時，當有學生對我訴說讀書的困難時，我都發現他所謂的「讀書困難」，其實是情緒疾病和心理問題。而那些麻煩往往是我當年遇過的，所以我可以詳細描述解決方法：
「你的問題其實是這個。你可以用這個方法。第一步是這樣。第二步是那樣… 有八成機會會成功。不行的話，你可以用這個後備計劃 …」

Lambda calculus 2
Prehistory
A few decades before modern computers were invented, the mathematician Alonzo Church developed a language called the lambda calculus. He intended it as a tool for investigating the foundations of mathematics. The first person to realize the practical connection between programming and the lambda calculus was John McCarthy, who created Lisp in 1958.

Friends
.
Treat your colleagues as friends. I apply the same basic rules to all my relationships, business and personal. I interact with my bosses and other colleagues exactly the same way I interact with friends. I’m sociable and laid back, I joke around, I’m honest, and if you’re being stupid I’ll let you know. This isn’t just some clever trick I use to make people like me. I just have a lot more fun without the smoke and mirrors that “professionalism” brings. And as a lot of bosses will tell you, it’s a lot harder to fire someone you like.

奇幻衝擊波 2
Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness that most frightens us.’ We ask ourselves, Who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? You are a child of God. Your playing small does not serve the world. There’s nothing enlightened about shrinking so that other people won’t feel insecure around you. We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It’s not just in some of us; it’s in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we’re liberated from our own fear, our presence automatically liberates others.

Problem solving (physics)
There are currently some problems that hinder a unified comprehension of Physics. Lee Smolin (in The Trouble with Physics, 2006) has listed 5 major problems:
1. Combine general relativity and quantum theory into a single theory.
2. Resolve the problems in the foundations of quantum mechanics.
3. Determine whether or not the various particles and forces can be unified in a theory that explains them all as manifestations of a single, fundamental entity.
4. Explain how the values of the free constants in the standard model of particle physics are chosen in nature.
5. Explain dark matter and dark energy.

Finishing is not.

Raising money
.
Livingston: What advice can you give about raising money?
Graham: The advice I would give is to avoid it. I would say spend as little as you can, because every dollar of the investors’ money you get will be taken out of your ass — literally in the sense that it will take stock away from you, but also the process of raising money is so horrible compared to the other aspects of business. You can’t work your way out of it like you can with other problems. You’re at other people’s mercy.

三種煩惱
這段改篇自 2010 年 4 月 8 日的對話。
有些煩惱，是因為思考不清晰而引起的。只要調整思考，你會發現所謂的「煩惱」，根本不成煩惱。
另一些煩惱，是真正的煩惱。它們是因為外在客觀的問題所引起的。要有具體行動，化解那些問題，才能令那些煩惱消失，而不能單憑調整思考。化解問題有兩個方法：「化」和「解」。
「解」的意思是，直接解決。「化」的意思是，有很多時候，「解決問題」的最好方法，未必是「直接解決」，而是「把問題 transcend 掉」，令到原本的問題不再重要。

Box
In quantum mechanics, a particle in a box has discrete energy levels, while a particle in infinite space has a continuum of energy levels. The discreteness comes from the “compactness” of the box. Can we use this idea to explain why spin is quantized? Yes! The “box” in this case, however, is the group SU(2)!
Geometrically, SU(2) is the same as what we mathematicians call S^3, or the 3-sphere – which is the unit sphere in R^4.

自我虛實篇
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.

Users
.
My philosophy on these types of companies — consumer-based Internet companies — is that you don’t need to worry about the business model initially. If you get users, then everything else follows. Basically any technology can be copied, any concept can be copied. In my opinion, what makes one of these companies valuable is the users. That can’t be copied.

互聯網普及之後，情況不再是那樣。Paul Graham 的另一篇文章講，摩爾定律令硬件廉價；開源軟件令軟件免費；互聯網令 市場推廣 便宜。利用互聯網的話，「市場推廣」不必再是成本高昂的工序。依靠「自僱工作」為生，沒有以前那麼困難。
有時，你所追求的東西，其實一早已經在你的身邊，只是你沒有留意。例如，互聯網在一九六幾年已經面世。但是， 1995 年才是互聯網發展史的轉捩點。那時，大眾才發現互聯網的存在（the public discovery of the Internet）。
Paul Graham 的再另一篇文章講，互聯網開始普及時（大約 1995 年），人們其實已經可以自由發表自己的文章，毋須任何中間人。但是，那時很少人這樣做。大部分人還習慣「要發表文章就要投稿和要出版社的認可」的思維模式。他們不能接受太美好現實：有了互聯網，出版文章竟然沒有困難。
結果，要等了 8 年（2003 年），才有大量人開始寫網誌（the public discovery of blogging）。

Debugging
Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.

Reassurance
.
It’s natural to seek reassurance. Most of us want to believe that the choices we make will work out, that everything will be okay.
… But everything is never okay.
Finding the bravery to shun faux reassurance is a critical step in producing important change. Once you free yourself from the need for perfect acceptance, it’s a lot easier to launch work that matters.
