A Brief History of Telescopes 1608 AD – Hans Lippershey‚ German-born Dutch lens maker‚ applied for a patent for his refracting telescope (using 2 lenses)‚ he intended them for use in the military. 1609-1610 – Galileo Galilei built his own refractor telescopes to observe the sky‚ and discovered Saturn’s rings‚ Jupiter’s moons‚ and along with many other significant discoveries. 1655 – Christian Huygens‚ a Dutch physicist and astronomer developed powerful lenses for refractor telescopes with his

Aristarchus (310 – 230 BC) Aristarchus of the isle of Samos was the first of the Greek philosophers and mathematicians to work out the workings of the universe and announce his discovery. Aristarchus‚ by observing the moon during a lunar eclipse‚ and estimating the angles between the Earth‚ Moon and Sun‚ as well as the size of the earth‚ was also one of the first astronomers to calculate the relative sizes of the Sun‚ Moon and Earth. Other astronomers before Aristarchus assumed that the

Physical science is everything thus it is our tool to unfold the mystery of the universe where man is its greatest occurrence. It is us‚ humans‚ who operate in accordance with the laws of nature and surely‚ we shall benefit from knowing and understanding the rules of the universe where we live. As a future educator‚ we play a major role in improving and saving lives‚ protecting the environment‚ and promoting knowledge in other

origin of the universe. In essence‚ this theory states that the universe began from an initial point or singularity which has expanded over billions of years to form the universe as we now know it. In 1959 a survey was conducted of scientists across America concerning their understanding of the physical sciences. One particular question asked “What is your concept of the age of the Universe?” More than two thirds of the scientists polled responded that there was no origin of the Universe. They believed

mountains and valleys‚ implying that the moon was not a perfect sphere‚ it stirred things up and started a domino effect of discoveries to be made about the sky for hundreds of years to come. Galileo Galilei was not planning to change the view of the universe like he did‚ and he had no idea that what he discovered would spark such a change in thinking. When he first pointed his homemade telescope to the sky in the winter of 1609‚ he was amazed by what the night sky really looked like (Maran 30). The telescope

Dark Matter and Dark Energy a small figment of the imagination‚ or the essences of our past‚ present‚ and future affecting the universe around us? What the human race believe the force that seemed to construct all of us may be not what it seems. An idea created upon literally nothing. May the nothing rather be something. A mad idea‚ maybe the start of the story to find out all of us. The energy force in space first thought up and documented by the scientist we all know‚ Albert Einstein. The teachings

Introduction Many people today have their thoughts on how the Earth was created. Christians take a biblical perspective of how the universe was created by a creator. One thought that Christians believe is that God created the earth and accomplished this in six days and rested on the seventh day. This is the model of how a week is set up and the model that we currently follow. Jon W. Green states “though differences of opinion exist for various doctrinal issues within Christianity‚ few are more

What Is Physics and What Are Its Uses? Physics‚ a branch of science‚ is traditionally defined as the study of matter‚ energy‚ and the relation between them. The interaction between matter and energy is found everywhere. In order for matter to move‚ it requires some form of energy. Sports show many good examples of the relationship between matter and energy. For instance‚ a pitcher requires energy to throw a baseball at the incredible speed and accuracy that is needed to keep the batter from

One quote that stuck with me during their encounter was‚ "And when you want something‚ all the universe conspires in helping you to achieve it" (Coelho 22). This quote held the most significance because it fit perfectly with the whole story. The omens and the people he met throughout the story was basically the universe helping him along his journey to find his Personal Legend. It goes to show that if your want is great enough‚ the end will be easier to find

When we shift our attention from the rat-race pursuit of going to work just to maintain what we’ve acquired‚ to a more meaningful quest for real understanding‚ we truly will separate ourselves form the animals. The exploration of our universe‚ for example‚ is in its zygote stage; we know little enough about the community in which we live. How can we be so egocentric as a race to be on a tiny planet in a vast universe and not explore
