I agree. It is amazing to see how new technology allows us to get really close to "exact" experimental procedures. My physics professor in university tells us that we can never make exact measurements; there is always some margin of error, be it human/experimental or random/circumstancial. It is important to do everything possible to make sure our measurements are as accurate as possible, although it can never reach exactitud.

Like we can make the value of 1/x go extremely tiny but it will never reach 0. Amazing.
