When Diane coaches Kurt, he describes two microns as one fiftieth the width of a human hair. However, in the speech Kurt gives, he says, "Take a hair from your head. Now imagine that you can split that hair down the middle, not once, not twice, but fifty times. That is the equivalent of two microns." This is incorrect. If he had sliced the hair into fifty equal widths, each of those widths would be two microns. His description instead has the hair being halved fifty times, resulting in the two halves resulting from the final split being one divided by two to the fiftieth power the width of a human hair.
