Creative constraints

Imagine you were asked to invent something new. It could be whatever you want, made from anything you choose, in any shape or size. That kind of creative freedom sounds so liberating, doesn’t it? Or … does it?

If you’re like most people you’d probably be paralyzed by this task. Why?

Brandon Rodriguez explains how creative constraints actually help drive discovery and innovation.

With each invention, the engineers demonstrated an essential habit of scientific thinking – that solutions must recognize the limitations of current technology in order to advance it.

Understanding constraints guides scientific progress, and what’s true in science is also true in many other fields.

Constraints aren’t the boundaries of creativity, but the foundation of it.

We cannot change anything until we accept it. Condemnation does not liberate, it oppresses.

機遇再生論 1.5

（請參閱本網誌，有關「重言句」、「經驗句」和「印證原則」的文章。）

「同情地理解」的意思是，有些理論，雖然在第一層次的分析之後，有明顯的漏洞，但是，我們可以試試，代入作者發表該理論時的，心理狀態和時空情境；研究作者發表該理論的，緣起和動機；從而看看，該理論不行的原因，會不會只是因為，作者的語文或思考不夠清晰，表達不佳而已？

（而這個意思，亦在「機遇再生論」的原文中，用作其理據。）

$P(A) = \frac{1}{N}$

$P($not $A) = 1 - \frac{1}{N}$

PhD

Holodny: Yeah, I noticed you don’t have a Ph.D. Are you not into the Ph.D. system?

Dyson: Oh, very much against it. I’ve been fighting it unsuccessfully all my life.

Holodny: Any reason in particular?

Dyson: Well, I think it actually is very destructive. I’m now retired, but when I was a professor here, my real job was to be a psychiatric nurse. There were all these young people who came to the institute, and my job was to be there so they could cry on my shoulder and tell me what a hard time they were having. And it was a very tough situation for these young people. They come here. They have one or two years and they’re supposed to do something brilliant. They’re under terrible pressure – not from us, but from them.

So, actually, I’ve had three of them who I would say were just casualties who I’m responsible for. One of them killed himself, and two of them ended up in mental institutions. And I should’ve been able to take care of them, but I didn’t. I blame the Ph.D. system for these tragedies. And it really does destroy people. If they weren’t under that kind of pressure, they could all have been happy people doing useful stuff. Anyhow, so that’s my diatribe. But I really have seen that happen.

Can it be Otherwise? 2.1.2 | The problem of induction 2.2

1. 當你的「相似事件」和「原本事件」的結果相同時，你只可以知道「原本事件」，可能是注定；你並不可以肯定「原本事件」，一定是注定，因為，你並不能保證，下一件「相似事件」的結果，會不會仍然和「原本事件」相同。

2. 當你的「相似事件」和「原本事件」的結果不同時，你亦不可以肯定「原本事件」，一定是偶然，因為，結果不同，可能只是由於「相似事件」和「原本事件」，不夠相似而已。

Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better.

— Emerson

One experience [almost] always helps another, because the first experience betters you, to deal with the second experience; even if the first experience is unpleasant.

（問：如果只是「類似」，當然可以有不同結果。你應該直接問：

（問：不是呀。在量子力學中，即使有兩組百分百一樣的物理系統，即使它們獲得完全相同的輸入，都可能有不同的輸出。）

「相同」的意思，並不是指「沒有可能找到任何分別」。

「相同」的意思是「分別小到不易察覺」。

You probably will make those mistakes anyway.

You cannot choose whether to make those mistakes or not.

All you can choose is whether to make those mistakes before or during the exams.

Things You Should Never Do

It’s important to remember that when you start from scratch there is absolutely no reason to believe that you are going to do a better job than you did the first time. First of all, you probably don’t even have the same programming team that worked on version one, so you don’t actually have “more experience”. You’re just going to make most of the old mistakes again, and introduce some new problems that weren’t in the original version.
