George Ellery Hale and the Hooker Telescope,cope drives had to be very good if timeexposures were to be made; electric drives lay in the future, but clockwork was adequate, and so were drives of the falling weight variety. Measuring instruments such as micrometers, attached to telescopes, also needed reliable drives, and of course spectroscopy was coming very much to the fore.作者: 植物學(xué) 時間: 2025-3-23 12:57
