Most engineers and scientists have at one point in time or another explained a behavior using the principle - Occam’s Razor [lex parsimoniae (law of succinctness)]. The first media mentioned of Occam’s Razor that comes to my mind was in the movie Contact, based on Carl Edward Sagan’s novel Contact. So what is Occam’s Razor?
entia non sunt multiplicanda praeter necessitatem
entities should not be multiplied beyond necessity
What that really translates in simple English is... in absence of strong evidence the most obvious answer must be the right answer. That leads to the next key question... what is an ‘obvious answer’? The not so COMMON SENSE based answer! Paradoxical isn’t it?
