Mathematical proofs are the gold standard of knowledge.
Once a mathematical statement has been proved with a rigorous argument, it counts as true throughout the universe and for all time.
The experience is the closest you can get to glimpsing the abstract order behind all things.
Notable mathematical proofs
The square root of 2: Can the square root of 2 be expressed as a rational number—that is, as a fraction of two integers? The discovery by the ancient Greeks that square root of two is an irrational number was considered so dangerous, that the geometer Hippasus was murdered to prevent the knowledge from being disclosed.
Geometric series: Is the repeating decimal 0.99999… less than 1? Or does it equal 1? The proof that 0.9999... is actually equal to 1 surprises many people and provides a launching point into the analysis of infinite geometric series in calculus.
Countably infinite sets: An eye-opening proof shows the counter intuitive notion that the set of all rational numbers is the same size as the set of all positive integers, even though there are infinitely many rational numbers between two consecutive integers.
