History is always in transit, even if periods, places, or professions sometimes achieve relative stabilization. This is the very meaning of historicity. And the disciplines that study history—both professional historiography and the other humanistic or interpretive social-scientific disciplines.

Administration (now the Federal Transit Administration) was established and the California Transit Association was established. Any book on California’s transportation history must be selective. For one thing, California transportation history is intertwined with larger national and international trends and technological changes.

Theodolite, 13 inch horizontal circle and 9 inch vertical circle, by Ertel & Sohn, Munich. Horizontal circle is graduated to 5 minutes and vertical circle to 15 minutes.

It is likely that this is the 'Universal Instrument' by Ertel listed by George Neumayer as part of the instrumentation at Flagstaff Observatory, Melbourne in The instrument was used to determine the astronomical meridian. The transit, thoroughout its years of development, lent itself well to adaptations for specialty use.

In William Schmoltz adapted William Burt's solar attachment to the transit. This allowed for location of the true meridian by solar observations, therefore bypassing the often inaccurate magnetic readings.

Other articles where Transit circle telescope is discussed: telescope: Astronomical transit instruments: of transit instruments—for example, the transit circle telescope, the vertical circle telescope, and the horizontal meridian circle telescope.

The transit circle determines the right ascension of celestial objects, while the vertical circle measures only their declinations. Clemence was assigned at first to the Time Service and later to the Nine-Inch Transit Circle Division under the direction of Morgan was a specialist in star catalogues and fundamental meridian circle observations.

Its gravitational effects could explain the unusual clustering of orbits for a group of extreme trans-Neptunian objects (eTNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than times that of the Earth. These eTNOs tend to make their closest approaches. It would be difficult to name any observatory in this country where observations of greater interest, as respects the physics of astronomy, have been made than those effected by Prof.

Young with the nine-inch telescope constructed by Alvan Clark for the Dartmouth College; or than the supplementary observations made by Young with a powerful.The first work on trigonometric functions related to chords of a circle.

Given a circle of fixed radius, 60 units were often used in early calculations, then the problem was to find the length of the chord subtended by a given angle. For a circle of unit radius the length of the chord subtended by the angle x.

A good transit map combines the best of both of those worlds and, consequently, can be the subject of much fanfare, as evidenced by the success of Mark Ovendeen's Transit .
