relation between a planet’s orbital period and its distance to the Sun. Galileo was a backer of Copernican theory. He constructed an astronomical telescope in 1609 and made several discoveries‚ some of which were sunspots‚ the features on the moon‚ and the different phases of Venus. Newton proved that the force from gravity along with the tendency of a planet to stay in straight-line motion results in elliptical orbits. The geocentric view had been based on philosophical debates of how people interpreted

taken as historical fact. God had created the Earth and the Heavens around. Man (and to a lesser extent woman) was the focus of God’s attention. The model of the cosmos was still that formulated by the Greek philosopher Ptolemy around 140 AD. The sun‚ moon‚ planets and stars all revolved around the earth in circular orbits. Back then‚ everyone “knew” that the earth stood still at the center of the universe. But there were problems with this model. Although the stars move smoothly through the heavens

position and movement of the stars. It was not until the invention on the optical telescope prior to 1608 that Ptolemy’s model was definitively disproven. Another flaw was that he believed that the Earth was the centre of the universe and the Sun‚ Moon and all other planets revolved around it. Telescopes have improved further still from the optical telescope that could only be used at night in fine weather‚ to the all-weather Radio telescope which detect radio waves coming from space‚ to the Space

by a phase diagram. It determines whether two or three substances are mutually miscible‚ whether the equilibrium can exist over a wide range of conditions‚ or whether the system must be brought to definite temperature‚ pressure‚ and composition before equilibrium is established. Interpretation of the phase diagram is usually done with the use of Gibb’s phase rule. It describes the relationship among the number of degrees of freedom (F)‚ the number of components (C)‚ and the number of phases (P) at
