It reached its peak in the Greco-Roman world, especially as recorded in the Tetrabiblos of Ptolemy. Natal astrology is based on the assumption that the positions of the planets at the time of our birth, as described by a horoscope, determine our future. However, modern tests clearly show that there is no evidence for this, even in a broad statistical sense.

Understanding the behavior of charges and the electromagnetic waves they produce has led to vast technological advances and the ability to examine the universe and make sense out of what we see.

Yes, for example, the Sun and the seasons, daylight, the Moon and tides, asteroids, and comets affect us on Earth. Astrology today is based primarily on the influence of the planets on individual lives. Sun-Sign Astrology is the most-popular form; this is based on the Sun’s position in the sky relative to background stars.

We know from the structures they built and, in some cases, the records that they left behind, that ancient people took an interest in the movements of those “wandering stars” we call planets today.

A number of the clubs do special activities, such as how to buy a telescope and how to use a telescope. And, a few still offer classes on making a telescope; the Eastbay Astronomical Society in the San Francisco Bay area is well-known for the telescopes attendees make in their Telescope Makers Workshop.
