predicting the properties of something that is impossible to make is impossible. Egad, not at all. The elements we use in circuit analysis, for example -- pure resistances, capacitances, inductances, sources, and so forth -- are all impossible to make. Yet we know their properties in exacting detail. One cannot cut a stick to a length of exactly pi meters, yet the properties of pi are precisely known. For that matter, we can't even make a stick that's exactly one meter long, but the meter is very well defined. Those are just a very few of the vast number of things which are impossible to make yet whose properties are known. Math, science and engineering wouldn't be possible without them.
