Pi Brexit
When math teachers in a school or state can’t see eye to eye on the degree of accuracy the number π should be given in a math question—for example, should the students be asked to take π to be 22/7 or 3.14?
In the aftermath of the “Pi Brexit” war, a red state in the US has recorded at least a dozen resignations from hardcore evangelical math teachers, who refuse to bulge unless the schools agree to use the biblical value of three for π.
