Problem Solving
The solution of the age
What the problem is
You can't look a big problem too directly in the eye
Everything works both ways
The kind of problem a city is
The problem of the house has not yet been stated
Clinging to ideas
A good question is better than a brilliant answer
A normal wooden pencil
Each fascinating crisis
You are agreeing to make a Thing
How to be a genius
Old solutions
As something we have never seen before
The technology shelf
Details first
Each pattern is a rule
When all you have is a hammer
Notes on the Synthesis of Form
Framing vs. Shaping
Learning to walk through walls
An Article by David R. MacIverI have a running joke that one of the most useful things I do when coaching or consulting is to say to people “Yes, that does sound like a problem. Have you tried solving it?”
Part of why this is a joke is that actually most of the useful work happens prior to the point - the hard part is actually articulating what is going wrong well enough that it seems like a soluble problem - but there is genuinely something useful about this, because often it feels people are looking for permission.
Without the external prompt, solving their problem is not something they noticed that they were allowed to do.
Delight in the imperfect
An Article by David R. MacIverI think part of the difficulty in allowing ourselves to properly delight in the imperfect, comes from conflating delighting in something with wanting it to happen. This isn’t the case. You can appreciate something as it exists while acknowledging its problems. You can see that a fire is beautiful without becoming a pyromaniac, and you can appreciate the absurdity of your political situation without thinking it’s good.
Even if a delight in the imperfect causes you to want more imperfection in your life (and it should), there is no shortage of imperfection to seek out. The imperfect is not scarce, it’s abundant. If you find imperfection delightful, you will never be short of things that delight you, even if you fix any given problem. Solving problems and smoothing out imperfections doesn’t remove the source of delight, it merely opens up new vistas for it. You could give yourself over totally to delight in the imperfect and never run out of things to explore, even without creating your own.
The Nature of Product
An Article by Marty CaganToo many product managers and product designers want to spend all their time in problem discovery, and not get their hands dirty in solution discovery – the whole nonsense of “product managers are responsible for the what and not the how.”
The Feynman Algorithm
A Definition- Write down the problem.
- Think real hard.
- Write down the solution.
The fastest way to learn something is to do something
An Article by David R. MacIverSuppose you have a problem to solve. What do you do?
Well, you sit down and think real hard, and after extensive and careful planning you try the well thought out and rigorous solution that you have thought up. Right?
No, wrong! Bad.
The correct thing to do when you have a problem is:
- Think for a short amount of time.
- Make sure it is safe to try things.
- Try something you think will work.
- Observe the result. If you succeeded, yay you solved the problem! If it didn't work, think about what that means for the nature of the problem and try again.
Scott and Scurvy
An Essay by Maciej Cegłowski…one of the simplest of diseases managed to utterly confound us for so long, at the cost of millions of lives, even after we had stumbled across an unequivocal cure. It makes you wonder how many incurable ailments of the modern world—depression, autism, hypertension, obesity—will turn out to have equally simple solutions, once we are able to see them in the correct light. What will we be slapping our foreheads about sixty years from now, wondering how we missed something so obvious?
Class 1 / Class 2 Problems
An Article by Kevin KellyThere are two classes of problems caused by new technology. Class 1 problems are due to it not working perfectly. Class 2 problems are due to it working perfectly.
...Class 1 problems arise early and they are easy to imagine. Usually market forces will solve them. You could say, most Class 1 problems are solved along the way as they rush to become Class 2 problems. Class 2 problems are much harder to solve because they require more than just the invisible hand of the market to overcome them.
...Class 1 problems are caused by technology that is not perfect, and are solved by the marketplace. Class 2 problems are caused by technology that is perfect, and must be solved by extra-market forces such as cultural norms, regulation, and social imagination.
Adding is favoured over subtracting in problem solving
A Research PaperHow would you change this structure so that you could put a masonry brick on top of it without crushing the figurine, bearing in mind that each block added costs 10 cents? If you are like most participants in a study reported by Adams et al. in Nature, you would add pillars to better support the roof. But a simpler (and cheaper) solution would be to remove the existing pillar, and let the roof simply rest on the base.
A series of problem-solving experiments reveal that people are more likely to consider solutions that add features than solutions that remove them, even when removing features is more efficient.
Do not propose solutions
A Quote“Do not propose solutions until the problem has been discussed as thoroughly as possible without suggesting any.
I have often used this edict with groups I have led—particularly when they face a very tough problem, which is when group members are most apt to propose solutions immediately.”
— Norman R.F. Maier
What we have known since long
A Quote by Ludwig WittgensteinThe problems are solved, not by giving new information, but by arranging what we have known since long.
Interaction of Color
The deception of color
In order to use color effectively it is necessary to recognize
that color deceives continually.What counts here – first and last – is not so-called knowledge
of so-called facts, but vision – seeing.Practice before theory
Instead of mechanically applying or merely implying laws and rules
of color harmony, distinct color effects are produced
– through recognition of the interaction of color –
by making, for instance,
2 very different colors look alike, or nearly alike.The aim of such study is to develop – through experience
– by trial and error – an eye for color.
This means, specifically, seeing color action
as well as feeling color relatedness.As a general training it means development of observation and articulation.
This book, therefore, does not follow an academic conception
of “theory and practice.”
It reverses this order and places practice before theory,
which, after all, is the conclusion of practice.50 reds
If one says “Red” (the name of a color)
and there are 50 people listening,
it can be expected that there will be 50 reds in their minds.
And one can be sure that all these reds will be very different.Not the what but the how
Our concern is the interaction of color; that is, seeing
what happens between colors.We are able to hear a single tone.
But we almost never (that is, without special devices) see a single color
unconnected and unrelated to other colors.
Colors present themselves in continuous flux, constantly related to
changing neighbors and changing conditions.As a consequence, this proves for the reading of color
what Kandinsky often demanded for the reading of art:
what counts is not the what but the how.Scotopic seeing
The sensitivity
and consequently the registration of the retina of an eye is different
from the sensitivity and registration of a photographic film.Normally, black-and-white photography registers all lights lighter
and all darks darker than the more adjustable eye perceives them.
The eye also distinguishes better the so-called middle grays,
which in photography are often flattened if not lost.This shows what a higher key in light can lose in photography.
The greatest advantage the eye has over photography
is its scotopic seeing in addition to its photopic seeing.
The former means, briefly, the retinal adjustment to lower light conditions.Disliked colors
We try to recognize our preferences and our aversions –
what colors dominate in our work; what colors, on the other hand,
are rejected, disliked, or of no appeal. Usually a special effort
in using disliked colors ends with our falling in love with them.Color intervals
The tune of “Good morning to you” consists of 4 tones. It can be sung
in a high soprano, a low basso, and in all in-between voices, as well as
on many levels and in many keys. It can be played on innumerable instruments.In all possible ways of performance, this melody will keep its character
and it will be recognized instantly.Why? The intervals of the 4 tones, that is, their acoustical
constellation (again comparable with a topographical relationship),
remains the same.Although it is not common practice, one can also speak of intervals
between colors.
Colors and hues are defined, as are tones in music, by wavelength.Any color (shade or tint) always has 2 decisive characteristics:
color intensity (brightness) and light intensity (lightness).
Therefore, color intervals also have this double-sidedness, this duality.Time and space
Tones appear placed and directed predominantly in time from before to now to later.
Their juxtaposition in a musical composition is perceived
within a prescribed sequence only.
Horizontally, the tones follow each other,
perhaps not in a straight line, but of necessity in a prescribed order
and only in 1 direction – forward.
Tones heard earlier fade, and those farther back disappear, vanish.
We do not hear them backward.Colors appear connected predominantly in space. Therefore,
as constellations they can be seen in any direction and
at any speed. And as they remain, we can return to them repeatedly
and in many ways.
This remaining and not remaining, or vanishing and not vanishing,
shows only 1 essential difference between the fields of tone
and color.The accuracy of perception in one field is matched
by the durability of retention in the other, demonstrating
a curious reversal in visual and auditory memory.A cook with taste
Observe the interior and exterior, the furniture and textile decoration
following such color schemes, as well as commercialized color “suggestions”
for innumerable do-it-yourselves.Our conclusion: we may forget for a while those rules of thumb
of complementaries, whether complete or “split”, and of triads and
tetrads as well.
They are worn out.Second, no mechanical color system is flexible enough
to precalculate the manifold changing factors, as named before,
in a single prescribed recipe.Good painting, good coloring, is comparable to good cooking.
Even a good cooking recipe demands tasting and repeated tasting
while it is being followed.
And the best tasting still depends on a cook with taste.Flexible imagination
By giving up preference for harmony,
we accept dissonance to be as desirable as consonance.Besides a balance through color harmony, which is comparable
to symmetry, there is equilibrium possible between
color tensions, related to a more dynamic asymmetry.Again: knowledge and its application is not our aim;
instead, it is flexible imagination, discovery, invention – taste.Does it have color?
Whether something “has color” or not is as hard to define verbally as are
such questions as “what is music” or “what is musical."The Weber-Fechner law
Exponential increases in physical stimuli produce linear perceptual increases.
Thinking in situations
Naturally, practice is not preceded but followed by theory.
Such study promotes a more lasting teaching and learning
through experience. Its aim is development of creativeness
realized in discovery and invention – the criteria of creativity,
or flexibility, being imagination and fantasy. Altogether
it promotes “thinking in situations,” a new educational concept
unfortunately little known and less cultivated, so far.Not of method but of heart
In the end, teaching is a matter not of method but of heart.
The teacher actually is right and always will gain confidence
when he admits that he does not know, that he cannot decide, and,
as it often is with color, that he is unable to make a choice
or to give advice.Besides, good teaching is more a giving of right questions
than a giving of right answers.Results of a search
This book presents results of a search, not of what is academically called research.
In addition to the dedication of this book, I should like to state that my students in color have taught me more color than have books about color.
Simple forms
The concept that “the simpler the form of a letter the simpler its reading” was an obsession of beginning constructivism. It became something like a dogma, and is still followed by “modernistic” typographers.
This notion has proved to be wrong, because in reading we do not read letters but words, words as a whole, as a “word picture.” Ophthalmology has disclosed that the more the letters are differentiated from each other, the easier is the reading.
Without going into comparisons and the details, it should be realized that words consisting of only capital letters present the most difficult reading—because of their equal height, equal volume, and, with most, their equal width. When comparing serif letters with sans-serif, the latter provide an uneasy reading. The fashionable preference for sans-serif in text shows neither historical nor practical competence.
