In 1897 the Indiana House of Representatives was persuaded by a mathematician (of sorts) to entertain a bill “introducing a new mathematical truth”. The new truth was a method, or more precisely methods, for computing the value of π. Since π is a transcendental number the methods could at best have achieved an approximation. In fact they yielded several inaccurate values, one as wild as 4. The legislators were doubtful enough to refer the bill to a committee (the Committee on Canals) and, when this reported favourably, to the Committee on Temperance. Eventually they had the sense to defer it sine die.
