TARDIS by producer Barry Letts, who felt that the new roundels resembled washing-up bowls stuck to the wall. However, as fate would have it the set was damaged in storage between production blocks and had to be rebuilt, so this particular design only saw service in the one serial. The TARDIS has at least two console rooms: the primary one most used throughout the programme's history, and the secondary console room used during Season 14 in 1976/77, which has wood panelling and a more antique feel to it. It had been designed to make shooting more comfortable for the camera crew.
Interior Schwarzschild metric spherically symmetric perfect fluid solution that was found. It was published on 24 February 1916, only three months after Einstein's field equations and one month after Schwarzschild's exterior solution. Interior Schwarzschild metric In Einstein's theory of general relativity, the interior Schwarzschild metric (also interior Schwarzschild solution or Schwarzschild fluid solution) is an exact solution for the gravitational field in the interior of a non-rotating spherical body which consists of an incompressible fluid (implying that density is constant throughout the body) and has zero pressure at the surface. This is a static solution, meaning that it does not change over time.
