George E. P. Box, Statistician, 1987:
Essentially, all models are wrong, but some are useful.
William Gibson, Science Fiction Author, 1993:
The future is already here -- it's just not very evenly distributed.
Fred Schneider, Cornell Computer Scientist, 2014:
I strive to write papers that will be the first paper, the best paper,
or the last paper on a subject.

Disproportionate returns (in research and investing) come from correct non-consensus forecasts.
A Fun Word: Skeuomorph
A derivative object that retains ornamental design cues from structures that were necessary in the original. Often used in technology, such common save icon depicting a now-obsolete floppy disk.
Stephen Hawking, Physicist:
The greatest enemy of knowledge is not ignorance,
it is the illusion of knowledge.
The Great Questions by Robert Fulghum:
Often expressed in anger (e.g., parent to child),
but better used for philosophical enquiry.
- What on earth have you done?
- What will you think of next?
- Who do you think you are?
Fred Brooks (quoted by Almasi & Gottlieb):
Einstein argued that there must be simplied explanations of nature,
because God is not capricious or arbitrary. No such faith comforts the
Norman Augustine (quoted by Gray & Reuter):
Software is like entropy. It is difficult to grasp, weights nothing,
and obeys The Second Law of Thermodynamics; i.e., it always increases.
Douglas Adams, author, futurist:
There is a theory which states that if ever anyone discovers exactly what
the universe is for and why it is here, it will instantly disappear and
be replaced by something even more bizarre and inexplicable. There is
another theory which states that this has already happened.
Jack Kilby, co-inventor of the integrated circuit, after being
introduced for his 2000 Nobel Prize as having launched
the global digital revolution:
When I hear that kind of thing, it reminds me of what the beaver told
the rabbit as they stood at the base of Hoover Dam: "No, I didn't build
it myself, but it's based on an idea of mine."
Don't tell me what you value, show me your budget, and I'll tell you what you value.
(Robert) Zak's Razor, 1997:
- Architects say, "It COULD work."
- Implementors say, "It SHOULD work."
- Verifiers say, "It WILL work."
A 21st Century Update, 2007,
by Shailender Chaudhry, Robert Cypher, and Anders Landin:
- Implementors say, "It WON'T work."
- Verifiers say, "It DOESN'T work."
- Architects say, "It MUST work."
Isaac Asimov, 1983 introduction to "The Caves of Steel" (1953), 1st book of "The Robot Novels":
R.U.R. added its somber view to that of the even more famous Frankenstein, in which the creation of another kind of artificial human being also ended in the disaster, though on a more limited scale. Following these examples, it became very common, in the 1920s and 1930s, to picture robots as dangerous devices that invariably destroyed their creators. The moral was pointed out over and over again that "there are some things Man was not meant to know."
Even as a youngster, though, I could not bring myself to believe that if knowledge presented danger, the solution was ignorance. To me, it always seemed that the solution had to be wisdom. You did not refuse to look at danger, rather you learned how to handle it safely.
After all, this had been the human challenge since a certain group of primates became human in the first place. Any technological advance can be dangerous. Fire was dangerous from the start, and so (even more so) was speech—and both are still dangerous to this day—but human beings would not be human without them.
