Fermi Estimation Lab
An interactive estimation lab: break down real-world Fermi questions (piano tuners in a city, breaths taken in a life, mass of all ants) into a chain of sub-estimates, tune each with a logarithmic slider, watch the running product, then see your order-of-magnitude error and which single guess cost you the most. Includes a free-build mode and a shareable result card.
