Richard Feynman and The Connection Machine - The Long Now
For Richard, figuring out these problems was a kind of a game. He always started by asking very basic questions like, "What is the simplest example?" or "How can you tell if the answer is right?" He asked questions until he reduced the problem to some essential puzzle that he thought he would be able to solve. Then he would set to work, scribbling on a pad of paper and staring at the results. While he was in the middle of this kind of puzzle solving he was impossible to interrupt. "Don't bug me. I'm busy," he would say without even looking up. Eventually he would either decide the problem was too hard (in which case he lost interest), or he would find a solution (in which case he spent the next day or two explaining it to anyone who listened). In this way he worked on problems in database searches, geophysical modeling, protein folding, analyzing images, and reading insurance forms.

Welcome to Symbolic regression | Function Discovery
If a researcher possesses domain knowledge and intuition for the appropriate input variables and the appropriate form of the functional relationship between inputs and the output, then classical regression techniques will efficiently optimize the parameters in the assumed model (e.g., by using ordinary or generalized least squares method for the given model structure). When the domain knowledge about the data generating system is limited, it is the task and the responsibility of the researcher to prune the data variables to an uncorrelated subset and guess the right model form. Symbolic regression, as opposed to regression techniques, does it for the researcher, and discovers both the form of the model and its parameters.

BBC - Future - Health - The psychology of Tetris
Tetris holds our attention by continually creating unfinished tasks. Each action in the game allows us to solve part of the puzzle, filling up a row or rows completely so that they disappear, but is also just as likely to create new, unfinished work. A chain of these partial-solutions and newly triggered unsolved tasks can easily stretch to hours, each moment full of the same kind of satisfaction as scratching an itch.

The other reason why Tetris works so well is that each unfinished task only appears at the same time as its potential solution – those blocks continuously fall from the sky, each one a problem and a potential solution.

How ‘systems thinking’ is making the cloud transparent — Cloud Computing News
“The lesson of boundaries is hard even for systems thinkers to get. There is no single, legitimate boundary to draw around a system. We have to invent boundaries for clarity and sanity; and boundaries can produce problems when we forget that we’ve artificially created them…
…There are no separate systems. The world is a continuum. Where to draw a boundary around a system depends on the purpose of the discussion—the questions we want to ask.”

"The right boundary for thinking about a problem rarely coincides with the boundary of an academic discipline, or with a political boundary. "

"Once you’ve become a doorknob expert, you should be able to accurately describe how that device should work. Then, you should start studying doors. [...]

Now you’re starting to become a room expert. You’ll also become a window expert, and a floor and ceiling and wall expert. [...]

As you work from the bottom up, you’ll find yourself looking at bigger and bigger issues – like how public spaces can foster community interaction, or how city design can alleviate congestion.

Signs that you're a good programmer - Software Engineering Tips
"If you're not encountering problems that are difficult for you to solve then you need a change of job or hobby or scenery or something. Look for opportunities to work with something new at your job or school, try hacking your Roomba, pick a bug in an open-source project that nobody has touched for months and fix it, try answering tumbleweed questions on StackOverflow that force you to look up something you didn't know."

In Praise Of Vagueness | Wired Science | Wired.com
[O]ne way to consistently increase our problem-solving ability is to rely on vague verbs when describing the problem. That’s because domain-specific verbs – actions which we only perform in particular contexts – inhibit analogical reasoning, making us less likely to discover useful comparisons. However, when the same problem is recast with more generic verbs – when we describe someone as “moving” instead of “sprinting,” for instance – people are suddenly more likely to uncover unexpected parallels. [...]

[V]agueness is a useful delusion, a nifty means of remaining committed to long-term goals. Reality is a deterrence."

A VC: Subconscious Information Processing
My dad made me stay up very late that night until I had completed [my project]. And he stayed up with me. He made sure I understood two things that evening. The first one is obvious. When assigned something, you do it and you do it on time.

But the second thing he explained to me was more subtle and way more powerful. He explained that I should start working on a project as soon as it was assigned. An hour or so would do fine, he told me. He told me to come back to the project every day for at least a little bit and make progress on it slowly over time. I asked him why that was better than cramming at the very end[...].

He explained that once your brain starts working on a problem, it doesn't stop. If you get your mind wrapped around a problem with a fair bit of time left to solve it, the brain will solve the problem subconsciously over time and one day you'll sit down to do some more work on it and the answer will be right in front of you.

Shifting the Burden - Whose Monkey Is It? by Donald E. Gray - developer.*, Developer Dot Star
This diagram shows the how the event "Computer Locks Up" can trigger one of two responses: a symptomatic response to make the problem go away quickly (B1), or a systemic response (B2) where the system becomes more capable of solving problems without external influence. This pattern occurs often enough that systems people have given it a name: "Shifting the Burden."

"George, the client, works for a major defense contractor. Recently George inherited a system he didn’t know much about. The system had suddenly started producing about 25% defects. At $300 to $ 25,000 per part, upper management was screaming to find the problem and solve it."

Wicked problem - Wikipedia, the free encyclopedia
"Wicked problem" is a phrase originally used in social planning to describe a problem that is difficult or impossible to solve because of incomplete, contradictory, and changing requirements that are often difficult to recognize. Moreover, because of complex interdependencies, the effort to solve one aspect of a wicked problem may reveal or create other problems.

A New Theory of Awesomeness and Miracles, by James Bridle, concerning Charles Babbage, Heath Robinson, MENACE and MAGE
"The interesting bit is at the bottom: it [the machine that eventually broke the Enigma code] didn't work, they “changed the frequency”, and it did. No idea why. Brilliant. “Change the frequency” is my new term for randomly poking things until they work, a kind of non-technical strategy for dealing with problems you don’t understand, but which yields results surprisingly often."

- Some problems are stable. These are for politicians.
- Some problems worsen steadily. These are for engineers.
- Some problems immediately threaten life, liberty or happiness. These are for physicians and soldiers.
- Some problems are a recurrent itch. These are for entrepreneurs.
- Some problems loom at the horizon of human foresight. These are for scientists.

Inri137 comments on I'm not as smart as I thought I was.
"People fail to graduate from MIT because they come in, encounter problems that are harder than anything they've had to do before, and not knowing how to look for help or how to go about wrestling those problems, burn out. The students that are successful look at that challenge, wrestle with feelings of inadequacy and stupidity, and begin to take steps hiking that mountain, knowing that bruised pride is a small price to pay for getting to see the view from the top. They ask for help, they acknowledge their inadequacies. They don't blame their lack of intelligence, they blame their lack of motivation."

Hayek, The Use of Knowledge in Society | Library of Economics and Liberty
"It is, perhaps, worth stressing that economic problems arise always and only in consequence of change. So long as things continue as before, or at least as they were expected to, there arise no new problems requiring a decision, no need to form a new plan."

Rands In Repose: Managing Nerds
"The world is full of knots and untying each has its own unique high. Your nerd spends a good portion of their day busily untying these knots, whether it’s that subtle tweak to a mail filter that allows them to parse their mail faster, or the 30 seconds they spend tweaking the font size in their favorite editor to achieve perfect readability. This constant removal of friction is satisfying, but eventually they’ll ask, “What’s with all the fucking knots?” and attack.

A switch flips when your nerd drops into this mode. They’re no longer trying to unravel the knot, they want to understand why all knots exist. They have a razor focus on a complete understanding of the system that is currently pissing them off and they use this understanding to build a completely knot-free product - this is the Second High."

Pay-and-display parking ticket machines are an example of an intensely technological piece of infrastructure. This project explores how we can use these ubiquitous and expensive boxes to make cities more responsive to the needs of those who live in them, and proposes a service through which ticket machines become a communication channel between citizens and their local authorities.

Birds can also be a nuisance because their droppings deface and accelerate deterioration of buildings and automobiles. Bird droppings are a common contaminant in grain destined for human consumption. Bird nests can clog drain pipes, interfere with awnings, cause electrical shortages, and make fire escapes hazardous.

Richard Feynman was fond of giving the following advice on how to be a genius. You have to keep a dozen of your favorite problems constantly present in your mind, although by and large they will lay in a dormant state. Every time you hear or read a new trick or a new result, test it against each of your twelve problems to see whether it helps. Every once in a while there will be a hit, and people will say: "How did he do it? He must be a genius!"

The Dangerous Art of the Right Question
"Real questions, useful questions, questions with promising attacks, are always motivated by the specific situation at hand. They are often about situational anomalies and unusual patterns in data that you cannot explain based on your current mental model of the situation, like Poirot’s letter. Real questions frame things in a way that creates a restless tension, by highlighting the potentially important stuff that you don’t know. You cannot frame a painting without knowing its dimensions. You cannot frame a problem without knowing something about it. Frames must contain situational information."
