HOROSCOPES Horoscopes are charts created by astrologers. A definition of a horoscope is: the illustration of the position of the sun‚ moon‚ and planets from a given location on earth‚ usually at birth. Which simply means‚ where everything in the universe was in relation to everything else when you were born. People have been finding their horoscopes for a long time now‚ it’s nothing new. The earliest known horoscope was from 409 B.C. where it started to spread in the East with the conquerors of

1) What do we mean by a geocentric universe? Contrast a geocentric view with our modern view of the universe. Geocentric describes the idea that everything revolved around Earth‚ compared to modern knowledge that everything revolves around the Sun (our star). 2) Briefly describe the major levels of structure (such as planet‚ star‚ galaxy) in the universe. Planet: (a) Orbits a star‚ (b) large enough for its own gravity to make it round‚ (c) has cleared most other objects from its orbital

caves. They didn’t see much sunlight. As time went on‚ mathematical aspects started to rise from observational astronomy. Some cave paintings became known as an understanding of the path the moon takes around the sun. This is known as the ecliptic. The ecliptic lead to the discovery of the zodiac. Stars‚ moons‚ and planets in the Paleolithic culture are not the stars‚ moons and planets of modern time that we know. They are those whose habitat is the Milky Way and the celestial sphere now.

Early trigonometry The ancient Egyptians and Babylonians had known of theorems on the ratios of the sides of similar triangles for many centuries. But pre-Hellenic societies lacked the concept of an angle measure and consequently‚ the sides of triangles were studied instead‚ a field that would be better called "trilaterometry".[6]The Babylonian astronomers kept detailed records on the rising and setting of stars‚ the motion of the planets‚ and the solar and lunar eclipses‚ all of which required

Earth’s revolution around the Sun‚ the solar day is a few minutes longer than the sidereal day. The Sun’s yearly path around the celestial sphere‚ or‚ equivalently‚ the plane of Earth’s orbit around the Sun‚ is called the ecliptic. Because Earth’s axis is inclined to the ecliptic plane‚ we experienceseasons‚ depending on which hemisphere (Northern or Southern) happens to be "tipped" toward the Sun. At the summer solstice‚ the Sun is highest in the sky‚ and the length of the day is greatest. At the winter

Hipparchian and Ptolemaic systems‚ the planets are assumed to move in a small circle called an epicycle‚ which in turn moves along a larger circle called a deferent. Both circles rotate clockwise and are roughly parallel to the plane of the Sun’s orbit (ecliptic). Despite the fact that the system is considered geocentric‚ the planets’ motion was not centered on the Earth but on what is called the eccentric. The orbits of planets in this system are epitrochoids. The epicycle rotated and revolved along the
