Similarly, square roots are a mathematical construct. Basically this is an argument between quantum mechanics and mathematical platonism. Pysicists hold that the platonic view of the world is not borne out by physical experimentation. If all physical quantities are discrete, not continuous, then there are no real world irrational quantities - every real world quantity can be reduced to an integer number of the fundamental unit for that quantity (charge, length, time, etc.).

Could you (or someone else expressing similar views in this discussion) explain how do we know that length and time are quantized? Or, if this is an argument by authority, point us to the authority i.e. an article with the aforementioned explanation...
