Fermi Estimation is a technique for making order-of-magnitude estimates of unknown quantities using basic reasoning and widely-known reference points. Named after physicist Enrico Fermi, who could estimate complex quantities (like the number of piano tuners in Chicago) with surprising accuracy from first principles, it develops the skill of producing defensible approximations when exact data is unavailable — essential for decision-making under uncertainty.

A thought experiment is a structured mental simulation used to explore the implications of hypotheses, test intuitions, and derive insights in cases where real experiments are impractical, impossible, or unethical. From Galileo's falling bodies to Einstein's relativity to Rawls's veil of ignorance, thought experiments have driven some of history's most important intellectual breakthroughs — by using imagination as a rigorous investigative tool.
