“The popular image of mathematics as a collection of precise facts, linked together by well-defined logical paths, is revealed to be false. There is randomness and hence uncertainty in mathematics, just as there is in physics.” (Paul Davis, “The Mind of God”, 1992)
“Randomness, chaos, uncertainty, and chance are all a part of our lives. They reside at the ill-defined boundaries between what we know, what we can know, and what is beyond our knowing. They make life interesting.” (Ivars Peterson, “The Jungles of Randomness: A Mathematical Safari”, 1998)
“[…] we underestimate the share of randomness in about everything […] The degree of resistance to randomness in one’s life is an abstract idea, part of its logic counterintuitive, and, to confuse matters, its realizations nonobservable.” (Nassim N Taleb, “Fooled by Randomness”, 2001)
“Mathematics, far from being stymied by this situation, finds enormous value in it. The fecundity of ‘randomness’ is astounding; it is an inexhaustible source of scientific riches. Could ‘randomness’ be such a rich notion because of the inner contradiction that it contains, not despite it? The depth we sense in ‘randomness’ comes from something that lies behind any specific mathematical definition.” (William Byers, “How Mathematicians Think”, 2007)
“A Black Swan is a highly improbable event with three principal characteristics: It is unpredictable; it carries a massive impact; and, after the fact, we concoct an explanation that makes it appear less random, and more predictable, than it was. […] The Black Swan idea is based on the structure of randomness in empirical reality. [...] the Black Swan is what we leave out of simplification.” (Nassim N Taleb, “The Black Swan”, 2007)
“The key to understanding randomness and all of mathematics is not being able to intuit the answer to every problem immediately but merely having the tools to figure out the answer.” (Leonard Mlodinow, “The Drunkard’s Walk: How Randomness Rules Our Lives”, 2008)
"The randomness which lies at the very foundations of pure mathematics of necessity permeates every human description of nature" (Joseph Ford)
“Our concept of randomness is merely an attempt to characterize and distinguish the sort of series which bamboozles the most people. […] It is thus irrelevant whether a series has been made up by a penny, a calculating machine, a Geiger counter or a practical joker. What matters is its effect on those who see it, not how it was produced.” (Spencer Brown)
