We recently published an article about the results of a 4.5-year program of research on gender’s influence on faculty hiring preferences for tenure-track STEM assistant professorships. Our methods brought up an interesting issue about the types of adjectives used to describe job applicants, one that we did not have space to address in the paper.

For millennia, fundamental units of time were referenced this way. The ever-changing Earth rotation interval was divided into 86,400 seconds. But Earth rotation is not constant and is unpredictable. This meant that the duration of a second had to be changed occasionally to maintain essential synchronization with Earth rotation.
