Man on a bicycle can go three or four times faster than the pedestrian, but uses five times less energy in the process. He carries one gram of his weight over a kilometer of flat road at an expense of only 0.15 calories. The bicycle is the perfect transducer to match man's metabolic energy to the impedance of locomotion. Equipped with this tool, man outstrips the efficiency of not only all machines but all other animals as well.

The order of magnitude in which the critical threshold of speed can be found is too low to be taken seriously by the passenger, and too high to concern the peasant. It is so obvious it cannot be easily seen. The proposal of a limit to speed within this order of magnitude engenders stubborn opposition. It exposes the addiction of industrialized men to ever higher doses of energy, while it asks those who are still sober to abstain from something they have yet to taste.

Beyond a certain speed, motorized vehicles create remoteness which they alone can shrink. They create distances for all and shrink them for only a few. A new dirt road through the wilderness brings the city within view, but not within reach, of most Brazilian subsistence farmers. The new expressway expands Chicago, but it sucks those who are well-wheeled away from a downtown that decays into a ghetto.

- Energy and Equity
What is generally overlooked is that equity and energy can grow concurrently only to a point. Below a threshold of per capita wattage, motors improve the conditions for social progress. Above this threshold, energy grows at the expense of equity. Further energy affluence then means decreased distribution of control over that energy.

It takes more time and effort and delicacy to learn the silence of a people than to learn its sounds. Some people have a special gift for this. Perhaps this explains why some missionaries, notwithstanding their efforts, never come to speak properly, to communicate delicately through silences. Although they "speak with the accent of natives" they remain forever thousands of miles away. The learning of the grammar of silence is an art much more difficult to learn than the grammar of sounds.

School divides life into two segments, which are increasingly of comparable length. As much as anything else, schooling implies custodial care for persons who are declared undesirable elsewhere by the simple fact that a school has been built to serve them.

My feeling is that when we prepare a program, the experience can be just like composing poetry or music; as Andrei Ershov has said, programming can give us both intellectual and emotional satisfaction, because it is a real achievement to master complexity and to establish a system of consistent rules.
Donald Knuth
The most important thing in the programming language is the name. A language will not succeed without a good name. I have recently invented a very good name and now I am looking for a suitable language.

Total traffic is the result of two profoundly distinct modes of production. These can reinforce each other harmoniously only as long as the autonomous outputs are protected against the encroachment of the industrial product.

- Learn You Haskell for Great Good!
Haskell is statically typed. This means that when you compile your program, the compiler knows which piece of code is a number, which is a string, and so on. Static typing means that a lot of possible errors can be caught at compile time. If you try to add together a number and a string, for example, the compiler will whine at you.
