Problem Solving

Explaining problems is good

Often in the process of laying out a problem, a solution will present itself. [3]


Occam's Razor

Entities should not be multiplied unnecessarily.

"Pluralitas non est ponenda sine neccesitate""Frustra fit per plura quod potest fieri per pauciora"William of Ockham
Occam's Razor is often considered synonymous with the slightly more strongly worded law of parsimony, or the rule of simplicty, which can be summarised as "the simplest explanation is usually the correct one."
"Everything should be made as simple as possible, but not simpler."Often attributed to Albert Einstein

Zebra

"Zebra is the American medical slang for arriving at a surprising, often exotic, medical diagnosis when a more commonplace explanation is more likely. It is shorthand for the aphorism coined in the late 1940s by Theodore Woodward, professor at the University of Maryland School of Medicine, who instructed his medical interns: "When you hear hoofbeats behind you, don't expect to see a zebra".Since horses are common in Maryland while zebras are relatively rare, logically one could confidently guess that an animal making hoofbeats is probably a horse." [1]

Minimum Message Length

"even when models are equal in their measure of fit-accuracy to the observed data, the one generating the most concise explanation of data is more likely to be correct" [2]
