Astrophysicist Charles Greeley Abbot (fifth Secretary of the Smithsonian Institution, 1928-1944) carrying the house-fly vane radiometer afoot up the Mount Wilson, California trail. Abbot made this instrument in Pasadena, California, but carried it by hand up the trail so as to not risk breaking it. The radiometer could measure a candle's heat at 3000 miles.
