The Cosmic Distance Scale,n this procedure is the measurement of the distance to Venus. The most precise way of obtaining this distance is through the use of radar techniques. Another method is described in Problems 2–2 and 2–3 at the end of this chapter.

Dynamics and Masses of Astronomical Bodies, all had common features and should form part of a single theory of gravitational interaction. To formulate the theory, he had to invent mathematical techniques that described the observations and showed their interrelationship. His struggles with the mathematical problems are recorded in his book . (Ne00).

Quantum Processes in Astrophysics, field equations of classical electrodynamics could be applied. These equations break down on the scale of atomic systems. The electron bound to a positively charged nucleus does not lose energy because of its accelerated motion, although the classical theory of radiation predicts that it should. In
