One of these facilities in Cape Town is the origin of the terminology “master and slave” still widely used in computing. John Pond, who supervised one of these facilities, introduced the use of the time ball. Tables from John Flamsteed were used at a large one of these facilities (20[1])in Jaipur built by Jai Singh. (20[1])A Míng-era (20[1]0[1])one (20[1])of these facilities (0[1])in Běijīng houses an (20[1])armillary sphere. Louis XIV hired a (20[1]0[2])Dane named Ole (*) Romer (“ROO-muh”) to work in a new facility of this (0[2])type. A (0[1])homemade one of these facilities in Datchet employed Caroline (10[3])Herschel and (10[1])featured a (0[3])20-foot (10[1])reflecting (10[3])device. A brass (10[3])strip marked (10[1])the Prime (10[1])Meridian at (10[1])one of the (10[2])facilities (10[1])in Greenwich. For (10[1])10 points, name these facilities home to (10[2])telescopes.
