"How spherical-cow philosophy makes hard physics problems easy". Archived from the original on 9 October 1999. In the space gravity simulator educational video game Universe Sandbox, a spherical cow was added as a user-placeable object in March 2023. Leonard Hofstadter with the punchline mentioning "spherical chickens in a vacuum", in " The Cooper-Hofstadter Polarization" episode. In the sitcom The Big Bang Theory, a joke is told by Dr. "Spherical Cow" was chosen as the code name for the Fedora 18 Linux distribution. References to the joke appear even outside the field of scientific modeling. A 2015 paper on the systemic errors introduced by simplifying assumptions about spherical symmetries in galactic dark-matter haloes was titled "Milking the spherical cow – on aspherical dynamics in spherical coordinates". For example, Consider a Spherical Cow is a 1988 book about problem solving using simplified models. The concept is familiar enough that the phrase is sometimes used as shorthand for the entire issue of proper modeling. Cultural references Ī drawing of a spherical cow on skis, with the text Approksimoidaan pyöreä lehmä ( Finnish for "We approximate a spherical cow"). A 1973 letter to the editor in the journal Science describes the "famous story" about a physicist whose solution to a poultry farm's egg-production problems began with "Postulate a spherical chicken". It is told in many variants, including a joke about a physicist who said he could predict the winner of any race provided it involved spherical horses moving through a vacuum. Shortly thereafter the physicist returned to the farm, saying to the farmer, "I have the solution, but it works only in the case of spherical cows in a vacuum." ![]() The scholars then returned to the university, notebooks crammed with data, where the task of writing the report was left to the team leader. A multidisciplinary team of professors was assembled, headed by a theoretical physicist, and two weeks of intensive on-site investigation took place. Milk production at a dairy farm was low, so the farmer wrote to the local university, asking for help from academia. ![]() The phrase comes from a joke that spoofs the simplifying assumptions sometimes used in theoretical physics. The metaphor and variants have subsequently been used in other disciplines. Originating in theoretical physics, the metaphor refers to physicists' tendency to reduce a problem to the simplest form imaginable in order to make calculations more feasible, even if the simplification hinders the model's application to reality. The spherical cow is a humorous metaphor for highly simplified scientific models of complex phenomena.
