188 Complexity Quotes

Quaternions came from Hamilton after his really good work had been done, and though beautifully ingenious, have been an unmixed evil to those who have touched them in any way.

The complexity of things - the things within things - just seems to be endless. I mean nothing is easy, nothing is simple.

Truth is a golden thread, seen here and there In small bright specks upon the visible side Of our strange being's party-coloured web.

Children are given Mozart because of the small quantity of the notes; grown-ups avoid Mozart because of the great quality of the notes.

Jarndyce and Jarndyce drones on. This scarecrow of a suit, has, in course of time, become so complicated that no man alive knows what it means. The parties to it understand it least; but it has been observed that no two Chancery lawyers can talk about it for five minutes, without coming to total disagreement as to all the premises.

I can't be as confident about computer science as I can about biology. Biology easily has 500 years of exciting problems to work on. It's at that level.

I define UNIX as 30 definitions of regular expressions living under one roof.

The anthropologists are busy, indeed, and ready to transport us back into the savage forest where all human things ... have their beginnings; but the seed never explains the flower.

Anyone who isn't confused really doesn't understand the situation.

It is not at all simple to understand the simple.

A junkyard contains all the bits and pieces of a Boeing 747, dismembered and in disarray. A whirlwind happens to blow through the yard. What is the chance that after its passage a fully assembled 747, ready to fly, will be found standing there? So small as to be negligible, even if a tornado were to blow through enough junkyards to fill the whole Universe.

The human mind is not rich enough to drive many horses abreast and wants one general scheme, under which it strives to bring everything.

I like a thing simple but it must be simple through complication. Everything must come into your scheme, otherwise you cannot achieve real simplicity.

The worst constructed play is a Bach fugue when compared to life.

It is clear to all that the animal organism is a highly complex system consisting of an almost infinite series of parts connected both with one another and, as a total complex, with the surrounding world, with which it is in a state of equilibrium.

Nothing is as simple as we hope it will be.

A labyrinth of symbols... An invisible labyrinth of time.

A writer is someone who can make a riddle out of an answer.

A 'goto' in Perl falls into the category of hard things that should be possible, not easy things that should be easy.

We don't have enough parallel universes to allow all uses of all junction types--in the absence of quantum computing the combinatorics are not in our favor...

The memory management on the PowerPC can be used to frighten small children.

If they think they can get anyone who could have better handled the complex and difficult issues surrounding North Korea, Iran and other controversies, they are not understanding the world right now.

It's strange how the simple things in life go on while we become more difficult.

Everything is explicable in the terms of the behavior of a small child.

Organisms are not billiard balls, propelled by simple and measurable external forces to predictable new positions on life's pool table. Sufficiently complex systems have greater richness. Organisms have a history that constrains their future in myriad, subtle ways.

I despair of persuading people to drop the familiar and comforting tactic of dichotomy. Perhaps, instead, we might expand the framework of debates by seeking other dichotomies more appropriate than, or simply different from, the conventional divisions. All dichotomies are simplifications, but the rendition of a conflict along differing axes of several orthogonal dichotomies might provide an amplitude of proper intellectual space without forcing us to forgo our most comforting tool of thought.

Evolution is an obstacle course not a freeway; the correct analogue for long-term success is a distant punt receiver evading legions of would-be tacklers in an oddly zigzagged path toward a goal, not a horse thundering down the flat.

Never trust any complicated cocktail that remains perfectly clear until the last ingredient goes in, and then immediately clouds.

Why should things be easy to understand?

You know what they're writing about Baby you know what they're writing about It's a thing called love down through the ages Makes you wanna cry sometimes Makes you feel like you wanna lay down and die sometimes Makes you high sometimes But when you really get in it lifts you right up.

There is no black-and-white situation. It's all part of life. Highs, lows, middles.

There will always be plenty of things to compute in the detailed affairs of millions of people doing complicated things.

All art is at once surface and symbol. Those who go beneath the surface do so at their peril. Those who read the symbol do so at their peril. It is the spectator, and not life, that art really mirrors. Diversity of opinion about a work of art shows that the work is new, complex, and vital.

The truth is rarely pure and never simple. Modern life would be very tedious if it were either, and modern literature a complete impossibility!

The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.

I became mentally bifocal, and so I learned early to understand that there is no such condition in human affairs as absolute truth. There is only truth as people see it, and truth, even in fact, may be kaleidoscopic in its variety. The damage such perception did to me I have felt ever since, although damage may be too dark a word, for it merely meant that I could never belong entirely to one side of any question. To be a Communist would be absurd to me, as absurd as to be entirely anything and equally impossible. I straddled the globe too young.

Can any of us fix anything? No. None of us can do that. We're specialized. Each one of us has his own line, his own work. I understand my work, you understand yours. The tendency in evolution is toward greater and greater specialization. Man's society is an ecology that forces adaptation to it. Continued complexity makes it impossible for us to know anything outside our own personal field - I can't follow the work of the man sitting at the next desk over from me. Too much knowledge has piled up in each field. And there are too many fields.

Crazy people do not apply the principle of scientific parsimony... they shoot for the baroque.

Science offers us an explanation of how complexity (the difficult) arose out of simplicity (the easy). The hypothesis of God offers no worthwhile explanation for anything, for it simply postulates what we are trying to explain. It postulates the difficult to explain, and leaves it at that.

Our interest's on the dangerous edge of things. The honest thief, the tender murderer, The superstitious atheist.

The world comes to us in an endless stream of puzzle pieces that we would like to think all fit together somehow, but that in fact never do.

A solved problem creates two new problems, and the best prescription for happy living is not to solve any more problems than you have to.

It has become clear that the legacy of the past decades we have to cope with is even worse than we anticipated or could anticipate in the joyful atmosphere of those first weeks of freedom. New problems are emerging day by day, and we can see how interconnected they are, how long it takes to solve them, and how difficult it is to establish priorities.

As with all great artists, Mozart expressed not only the soul, the taste and the aroma of his epoch, but also the spiritual world of man-man for all ages, in all the complexity of his desires, his struggles and ambivalence. Some of us, who only identify in Mozart a certain aristocratic refinement, may find these words strange. Often we meet with a condescending attitude towards him, to his music, reminiscent of chiming bells in a music box! ...'It's very nice, but not for me' say such people, 'give me passion - Beethoven, Brahms, tragic, monumental...' Such comments only reveal one thing, these people don't know Mozart.

... it seems that it would take less than half a million years to evolve a good camera eye ... It's no wonder 'the' eye has evolved at least 40 times independently around the animal kingdom ... It is a geological blink.

Nilsson and Pelger began with a flat retina atop a flat pigment layer and surmounted by a flat, protective transparent layer. The transparent layer was allowed to undergo localised random mutations of its refractive index. They then let the model deform itself at random, constrained only by the requirement that any change must be small and must be an improvement on what went before ... The results were swift and decisive. A trajectory of steadily mounting acuity led unhesitatingly from the flat beginning through a shallow indentation to a steadily deepening cup, as the shape of the model eye deformed itself on the computer screen. The transparent layer thickened to fill the cup and smoothly bulged its outer surface in a curve. And then, almost like a conjuring trick, a portion of this transparent filling condensed into a local, spherical subregion of higher refractive index. Not uniformly higher, but a gradient of refractive index such that the spherical region functioned as an excellent graded-index lens.

When I wrote this program, I never thought that it would evolve anything more than a variety of treelike shapes. I had hoped for weeping willows, cedars of Lebanon, Lombardy poplars, seaweeds, perhaps deer antlers. Nothing in my biologist's intuition, nothing in my 20 years experience of programming computers, and nothing in my wildest dreams prepared me for what actually emerged on screen. I can't remember exactly when in the sequence it first began to dawn on me that an evolved resemblance to something like an insect was possible. With a wild surmise, I began to breed, generation after generation, from whichever child looked most like an insect. My incredulity grew in parallel with the evolving resemblance ... I still cannot conceal from you my feeling of exultation as I first watched these exquisite creatures emerging before my eyes. I distinctly heard the triumphal opening chords of 'Also Sprach Zarathustra' (the 2001 theme) in my mind. I couldn't eat, and that night 'my' insects swarmed behind my eyelids as I tried to sleep.

The Second Law of Thermodynamics states that all energy systems run down like a clock and never rewind themselves. But life not only 'runs up,' converting low energy sea-water, sunlight and air into high-energy chemicals, it keeps multiplying itself into more and better clocks that keep 'running up' faster and faster. Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organize themselves into a professor of chemistry? What's the motive? If we leave a chemistry professor out on a rock in the sun long enough the forces of nature will convert him into simple compounds of carbon, oxygen, hydrogen and nitrogen, calcium, phosphorus, and small amounts of other minerals. It's a one-way reaction. No matter what kind of chemistry professor we use and no matter what process we use we can't turn these compounds back into a chemistry professor. Chemistry professors are unstable mixtures of predominantly unstable compounds which, in the exclusive presence of the sun's heat, decay irreversibly into simpler organic and inorganic compounds. That's a scientific fact. The question is: Then why does nature reverse this process? What on earth causes the inorganic compounds to go the other way? It isn't the sun's energy. We just saw what the sun's energy did. It has to be something else. What is it?

Mozart is the most inaccessible of the great masters. ~ Artur Schnabel

The sonatas of Mozart are unique: too easy for children, too difficult for adults. Children are given Mozart to play because of the quantity of notes; grown-ups avoid him because of the quality of notes. ~ Artur Schnabel

It is complex
