WebMeasurement theory is the philosophical account of the practice of measurement in science. Its main historical landmarks parallel the history of quantitative science. First, Euclid liberalized the concept of ratio to explain how incommensurable quantities are measured via (whole) numbers. WebDec 19, 2014 · Measure here means Lebesgue Measure (there are others) and measure generalizes the "length" or "size" of a set. It allows us to measure sets which we couldn't do otherwise. We still can't measure EVERY set out there on the real number line but we can measure a lot more than we could before.
