For centuries humans have looked up at the sun, the moon and the stars, but we could only see what our eyes allowed us to see. However during the early 17th Century the physicist Galileo improved and pointed one of the first telescope towards the sky which signaled a new era of astronomy (Dunbar, 1). The purpose of the telescope like any other optical device, is to produce outgoing parallel rays of light that are then focused on the retina by the relaxed eye (Falk, 168). During the early 17th century the physicist Galileo Galilei took the two-powered spyglass, which was used by the army to spot distant objects, and increased its magnification to the point where he could see the moons craters. This paper will explore types of telescopes, understand how they work, and will comprehend their uses and limitations.
Telescopes can be categorized into the three core categories, refracting, reflecting and catadioptric. In most scopes the objective lens is the optical component which gathers light from the observed object and focuses the light rays to produce a real image. The eyepiece is the part which the human eye looks through, and is used to gather more light. The most important attribute of any telescope is its aperture, which ultimately determines how sharp and bright the images are. Galileo used a refracting telescope to view the moon and stars back in the 1600s. The refracting telescope consists of an objective lens and an eyepiece (Falk, 169). On the refracting telescope the big convex lens between the object and the telescope is the objective lens. It gathers and bends the light into a bright focal point at which point the eyepiece brings this real image into focus all inside a long thin tube, although it is inverted. To fix the inverted image problem, the Galilean telescope offers the same design as the refracting telescope, but the eyepiece is a negative concave lens which flips the image giving us an upright image.
Planets in Our Solar System From the beginning of time man has looked to the skies from intrigue and for answers and explanations. Many objects in space have observed, such as stars, constellations, galaxies, plants and moons. These celestial objects have been looked upon as spiritual and even ...
The Galileo will also house a state of the art hospital, were all research and authorized experiments will be conducted. The Urratio Hospital ,named after Dr.Lauren Urratio the founder of the Galileo's first research department,will have the best doctors and nurses that space can provide. ... Supplies like paper towels, toothpaste, soap, etc. will be delivered with food and water. ... A large library, housing fifty telescopes gives the people of the Galileo a place to relax and explore. ...
Research led to the idea that the reversals of Earth's magnetic field may also be periodic. ... (Muller 2001) The star is most likely visible with a small telescope. ... The search for the star began at Leuschner Observatory, but the telescope which was being used was not designed for such use. A new telescope was constructed and will be moved to a mountain near Monterey once final testing is completed. ... However, now after writing this paper, I am more skeptical and there are questions that I would want answered more clearly before giving my support to the theory. ...
The third period, which was as long as the other two combined was where Newton was a highly paid government official in London with little or no interest in mathematical research. ... He then proposed and constructed a reflecting telescope. ... In 1672 Newton was elected to the Royal Society after donating a reflecting telescope. Also in 1672 Newton published his first scientific paper on light and color in the Philosophical Transactions of the Royal Society. The paper was well received but Hooke and Huygens objected Newton's attempt to prove that light consists of the motion of...
Think of space as a piece of paper, which is bent over on itself. If a weight in put on top of the paper it will sag towards the centre. ... This is because there would not be enough negative energy to hold it open. (1) The Hubble Space Telescope's latest picture is of swirling gas surrounding a black hole at the core of a distant galaxy. ... Current research indicates that it is impossible to open wormholes bigger than 10-35 metres. ...
Newton chose Optics for the subject of his first research topic. ... Later Newton failed at completing a few parts of his experiments and abandoned his hopes of making a refracting telescope, which should be achromatic. Instead he designed a reflecting telescope and later the reflecting microscope. Newton wrote a paper on fluxions in October 1666. ... In his 1666 paper Newton discusses the converse problem, given the relationship between x and y'/x' find y. ...
This paper introduces and defines grid computing for businesses and describes how Oracle 10g products implement a grid infrastructure. ... Origins of Grid Computing Grid computing was conceived in the academic and research communities. Much like internet computing, which grew from the communication needs of dispersed scientific researchers, grid computing originated from the needs of the scientific community's needs to: Create a dynamic computing environment for sharing resources and results Scale to accommodate petabytes of data, and teraflops of computing power And keep...
Computers are integral to most astronomical research, both observational and theoretical. ... The next division is the solar-system astronomy, which tells us that the planets can be studied with telescopes from the ground, from spacecraft in the earth's orbit. ... The last few divisions which are astrometry, the study of the positions and motions of stars and other celestial objects, telescopes that new technologies have led to advances in telescopes in all parts of the spectrum, computational astronomy which is the small and moderate sized computers that run telescopes and assist with ...
