The refracting telescope was one of the first telescopes, but it is not the sole method for viewing the stars. During the 17th century, as an alternative to the refractive telescope, Newton was credited with build the first reflecting telescope. The reflecting telescope does not use a convex lens, but instead uses a very large concave parabolic mirror to gather and focus the light from the object onto a flat secondary mirror which reflects the image out of an opening at the side of the main tube (Sharma, 1). The eyepiece which we look through is in that tube sticking out the side near the top of the big telescope and allows us to see a similar image as produced by a refracting telescope. The refractive and reflective telescope are both popular, but the third and final category is somewhat of a mixture of the two. The Catadioptric telescope uses a combination of mirrors and lenses to fold the optics in order to form an image. The light from the object enters through a correcting lens which acts as the objective, then hits a spherical primary mirror and is reflected back and forth throughout the tube until the image is then formed at the eyepiece (Sharma, 1). These three designs are used for similar purposes but each has its advantages and disadvantages.
The Refracting telescope is clearly the most common form of the telescope since it is so simple and cheap to make. Because it is so cheap and easy to make it can be found in mass circulation among youth astronomers. This design despite its simplicity it is good for viewing distant terrestrial objects, and with a large aperture it is perfect for stargazing. Unlike other designs the sealed tube protects the optical components from damage and from image degrading air currents thus making it a rugged little device (Sharma, 1). Although the refracting telescope has many advantages over its counterparts, it still has limited practical usefulness.
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 ...
