Lecture – 1 Classical Physics — 1 Comment

  1. Rather than wait for a comment about why I put such basic physics stuff on this site that is dedicated to measurements. My answer is: it’s one place to start for anyone interested in the nitty-gritty about measuring things.

    My first real measurement class in college involved doing repeat measurements of the diameter of a small length of steel pipe. That was a physics class!

    We used a micrometer and were a bit surprised to find that there was no one answer. In fact, after making 10 sets of measurements we were able to calculate (estimate) the average diameter and another statistic called the Standard Deviation. It went downhill from there, I must admit.

    There is no such thing as a perfect measurement, only some that are a bit more precise than others. Knowing the science helps to understand the reasons for variations in results. At least it does for me.
