Step 101: The diameter of human hair.
The range, from 17 to 181 microns, begins within step 100, includes all of 101 and goes into 102. Here we are in the middle of the universe, between the first and last notation or step, and we can only be off by a hair. Unusual? No, it is beyond belief.
Within the human scale the diameter of hair is still quite small; yet, if compared to the Planck Length, it is the size of a galaxy. And then, of course, in the large-scale universe, it is seemingly lost and inconsequential, yet it is very, very close to being in the center of the universe.
Key Ideas: Also, look at steps 100, 102 and 103, all in the range of the center of the universe and each of them profoundly human.
