"Science" uses both experimentally-derived numbers (e.g. G, > c, the mass of the electron) and numbers known exactly (√2, e, π).
Off-topic, c being a fundamental constant is actually in the latter category. Its *exact* value is 299792458 m/s. The length of the meter, on the other hand, is defined as the distance traveled by light in a vacuum in 1/299792458 seconds and is subject to the precision of measurements. -- https://mail.python.org/mailman/listinfo/python-list
