5 example of quasi-science, contrasting math vs computing. In math, things are well defined, things either correct, or not. In programing, you have methodologies, “patterns”, OOP, FP, haskell vs clojure, “unix philosophy” etc, cuz it's not well defined.

The thing is that, they push it, usually inventing lots jargon on the way, and creating a cult following.

2 famous programers who are quasi-pseudo-science are Larry Wall, Martin Fowler.

3 the things they say, is not exactly incorrect, since they are not never about math, but usually methodology/approach, naming. Our scientific basis to access approach, jargons, is not mature or practical, since such ties with culture. So, we can't bluntly say they are wrong.

i realized, that is so weird, cuz the author is creating/following a sort of “new way of thought” on visualization. The quasi-science is similar to Buckminster Fuller 's stuff eg “spaceship earth”, ephemeralization, synergetic, are quasi-pseudo-science/engineering.

once you got into a new lang for a few years, the novelty effect wears off. Like, once you learned Chinese character, those tattoo by Westerners looks very stupid.

in general, novelty is appealing, exotic, refreshing, cuz you got tired of familiarity. Like, westerners love zen dao acupuncture ninja, or tatoo in Chinese, or rune chars as keyboard label. But for those who grew up with them, ur like 3 years old.

everytime you learn a new lang, you get a novel experience. Was master of Mathematica in 1995. Then learned perl i thought wow all things are strings, neat. Then python 2005, thought wow so great not to need $sigil or {}... but looking back, it's all novelty effect.

your need about 5 hours to study this. After that, you'll have good understanding.
This i wrote in 1997, but is the most cited by professors and academic papers.
