Checks and Balances
Politics
Split legislative, executive, and judicial power among different hands so that no single branch can govern unchecked.
Source: After Montesquieu
The design assumes ambition must be made to counter ambition, since virtue alone cannot be trusted to restrain power.
Goldbach's Conjecture
Mathematics
Every even number greater than two is claimed to be a sum of two primes; checked past enormous bounds, proved for none in general.
Source: Christian Goldbach's conjecture, 1742
Easy to state and unproved for nearly three centuries; it shows how far verification can run ahead of proof.
No Center, No Edge
Physics
The Big Bang was an expansion of space itself happening everywhere at once, not an explosion into empty space from one point.
Source: After the standard hot Big Bang model
There is no location you could travel to and stand at the site of the Big Bang; every point in space was equally involved.
Attachment Styles
Psychology
Ainsworth watched how infants reacted when a parent left and returned, then sorted the reactions into secure and insecure patterns.
Source: After Mary Ainsworth's Strange Situation
This lab procedure became the basis for most later attachment research, in children and in adult romantic relationships alike.
Achilles and the Tortoise
Philosophy
Achilles gives a tortoise a head start; by the time he reaches its starting point, it has moved on, forever slightly ahead.
Source: After Zeno of Elea, preserved in Aristotle's Physics
Zeno's math seems to prove the faster runner never catches up, though everyone has watched a fast runner win.
Neural Darwinism
Biology
Brain wiring gets selected during development and experience much like traits get selected in evolution: connections that work are kept, others pruned.
Source: After Gerald Edelman
An analogy, not a literal claim that neurons reproduce; critics argue it stretches selection language past where it explains much.
