abstract:In science, particularly in physics or engineering education, a Fermi problem, Fermi question, or Fermi estimate is an estimation problem designed to teach dimensional analysis, approximation, and the importance of clearly identifying one's assumptions. Named after physicist Enrico Fermi, such problems typically involve making justified guesses about quantities that seem impossible to compute given limited available information.
Theeriddle is known as a Fermiproblem, named after the physicist Enrico Fermiwho was known for hisability tomake good calculationswithvery littleinformationor evennone.
