The human eye is not perfect. Most of us are able to see a limited part of the light spectrum, while some have vision problems like the diminished vision or differences in the perception of color. You know how some people describe a fish they caught by spreading their hands or saying the measured length or weight? Well, you may also notice that the distance between the hands changes, especially with a storyteller that likes to exaggerate. The same inconsistency can be applied to our empirical measurements. The value 0 represents nothing, non-existence, or neutrality, while 1 represents a whole unit. Our application of these basic measurements varies in accuracy depending on what is measured. For example, the temperature known as "absolute zero" is supposedly -273.15 degrees Celsius / -459.67 degrees Fahrenheit, while it is stated as 0 degrees in on the Kelvin or Rankine scale*. Alternatively, consider the measurement of ingredients while cooking. You measure one tablespoon of sodium, four liters of water, and a pound of pasta noodles. While precise measurement is not essential in this scenario, it illustrates how our methods of measurement can create error. Our ability to abstract calculations of 1 meter is limited to what we perceive as .5 meters, .25 meters, .025 meters, .0025 meters, .0000000025 meters, etc. That is not to say that a diligent student can not do this, but it is not natural for us to engage readily in such perception. I had a clear direction with this thread about how our science is only as good as our math, but then I started thinking about ants and their scale to humans and our scale to the universe, and now I'm just tired.
