John Huchra

摘要

John Peter Huchra worked more hours in a day and observed more nights in a year than anyone else I know. In doing so, he helped establish our modern picture of the Universe as a frothy place, with sheets and filaments of galaxies enveloping giant empty voids. He also pioneered a technique to obtain more accurate measurements of the Hubble constant - a step that ultimately helped astronomers to pin down the age of the Universe as 14 billion years.
