Fermi Estimation

TagLast edit: 2 Feb 2021 10:18 UTC by Yoav Ravid

A Fermi Estimation is a rough calculation which aims to be right within ~an order of magnitude, prioritizing getting a good enough to be useful answer without putting large amounts of thought and research in rather than being extremely accurate.
