This is a comprehensive guide to the basic movements we can observe in the sky. Schultz describes the daily movement of the stars from different parts of the earth (including southern hemisphere throughout). Included are the sun's pattern of the day and of the year, the moon's various periods, nodes and eclipses, as well as the planets' apparent movement and loops, conjunctions and transits. The appendix contains tables of periods and rhythms, and a guide to important occurrences to the year 2010.

Visual Astronomy introduces the basics of observational astronomy, a fundamentally limitless opportunity to learn about the universe with your unaided eyes or with tools such as binoculars, telescopes, or cameras. The book explains the essentials of time a

If the solar system is regarded as a moving mass point system, then both the planet m and the sun M move around the solar system mass center O. According to the motion law of the mass point system and the centripetal force formula of the curve, it can be determined through theoretical analysis and mathematical derivation: (1) Kepler's law of planetary motion contradicts the motion rules of mass point systems. (2) The universal gravitational force F between planet m and sun M. K is the new gravitational constant. The force F' on the object m in the inertial frame S'. In the formula, V' is the velocity of the object m in the inertial frame S', and u is the velocity of the inertial frame S' in the cosmic space reference frame. In addition, the author designed three new optical experiments based on the light interference theory to verify whether the principle of constant speed of light conforms to objective facts. Experiment 1. Using the new front and rear hole laser interferometer for verification; Experiment 2. Verification of using long and short optical path Michelson interferometers; Experiment 3. Verification of using a double-hole interferometer.
