Dr. Jonathan "Josh" Grindlay
An edited interview with Dr. Josh Grindlay concerning the use of measurements of star brightness
from the Digital Access to a Sky Century @Harvard to measure the dimming (or not) of Tabby's Star over a Century. Grindlay critiques Hippke's paper that found dimming in several stars in the DASCH data, and also Schaefer's claim that Tabby's Star (KIC 8462852) is slowly dimming.

Erratum: I said "Schaefer" in the epilogue when I meant "Grindlay"
