Recommended: The invention of the telescope essay
For centuries, mankind has always pondered upon the wonders that is beyond our planet, the Earth. The invention of the telescope has vastly improved our view of the skies, sharpening our perception of the universe and penetrating ever deeper, to the furthest edges of time and space. The underlying roots to the invention of the telescope is vague and thought to have started around during the 13th century. An accidental discovery made by a glassmaker during this era, resulted in the development and defined the early beginnnings of spectacles. The glassmaker discovered the magnifying effect of glass when objects glanced through a glass disk appeared clearer and larger in size. It was not until the 17th century which convex lenses were utilised together to create what we now call the “telescope”.
The actual, true inventor of the telescope will never be known,however, a dutch spectacle maker by the name of Hans Lippershey was the first person to patent. The patent was denied as there were disputes over who was the foremost and earliest inventor of the telescope. The underlying reasoning laid upon the claims of other merchants who also declared themselves to have conceived the invention, whom one of which is Lippershey’s competitor, Zacharias Jansen. Hans figured that if he combined a convex and a concave lens with one another, it would greatly magnify the object of interest when observed through the newly merged lens. During this time the telescope was not used to observe the stars but rather as a war tool by the navy. The discovery and creation of the telescope spread like wildfire which led a physicist and astronomer named Galileo Galilei to construct the device in 1609. Galileo saw the potential of the telescope which led to th...

Journal Eleven In “The Telescope Effect” Shankar Vedantam states his theories on why people are so willing to help a single person deal with tragedy. However, when it comes to mass tragedies or terror people seem to shy away from helping or lending a hand. Vedantam seems to bring to light some issues people have in their minds when it comes to who they provide help for. Vedantam in the beginning of the essay tells the story of a Dog named Hokget and how the puppy was abandoned by her owner on a big tanker lost at sea.
Because of his discoveries and eighteen years of experience teaching at Padua, Galileo grew more and more famous, and his salary had almost tripled. Galileo caught word one summer afternoon of a mechanism that existed in the Netherlands that could make distant objects appear closer. Intrigued by the idea, he decided to make one of these contraptions of his own. To do this, Galileo used spectacle lenses, which at first only magnified things two to three times their size, but Galileo then improved this to eight or nine times their size
Galileo Galilei, (1564-1642) an Italian mathematician and astronomer, won the respect and admiration of many people of his time because of his inventions. He constructed a military compass, an instrument for measuring the expansion of liquids, and one of the early telescopes with which he discovered Jupiter's satellites, irregularities on the surface of the moon, star clusters in the milky way and spots on the surface of the sun. He was initially skeptical of Copernicus' theory however his observations and experiments affirmed his diagram of the universe. Critics attacked Galilei's findings. They said that his "discoveries" were ridiculous to believe and that it was only is imagination or dreams. Galilei wrote a letter to Dowager Grand Duchess trying to reconcile his astronomical observations with the Bible.
When a curious observer looks to the cosmos, he/she travels back in time hundreds, thousands, millions, even billions of years. The photons from the mysterious stars he/she is looking at have traveled through time at 186,000 miles per second, until his/her eyes caught them. Light is the one particle that sheds luminosity over everything, and is the only way of seeing the elusive and magnificent nature of the universe. But to understand light is too understand its speed—a speed so great that nothing with mass can ever reach it.
Astronomy’s beginnings can be considered to go back as far as humankind has looked up at the sky in wonder. A simple question then led to an answer that is still being uncovered today. That question: “What is everything up there?” Two-thousand years later, some questions have been answered. Many still remain. However, the process in which these answers have been obtained has not been simple. Many times throughout history, astronomers have believed the answer was in sight and tenaciously believed the idea, only to discover they were wrong years later. These astronomical fads have held the progress of astronomy, and consequently almost all other branches of science, back for hundreds of years as the truth was sorted out. One of the first examples of this was the model of solar system. Aristotle first reasoned that the Earth was at the center and the sun and planets traveled around it on crystalline spheres (Baron 44). The most distant sphere was black and had many small holes punched in it (Baron 44). Behind that was the light from Heaven which shown through the holes making the stars (Baron 44).
In 1610 he was one of the first people to use the telescope to observe
Although telescopes has been around for several hundreds of years, there has been great discrepancy as to who invented it first. Here is one authors opinion. Lippershey was a Dutch spectacle marker during the early 17th century (approximately 1600). He was one of the first who created the "looker" (now called telescope) by placing two pieces of lenses together. The discovery that placing lenses together can magnify images were made by children who took Lippershey's spectacles and looked at a distant church tower.
There is a long history of astronomy in science fiction. Some of the earliest can be seen with the Greeks, with their tales of gods representing the parts of the universe they could see. Other cultures began writings of men going beyond the limits of the atmosphere as early a...
Whenever we watch movies about space, the movie tends to influence our perspective of what is out there in space and how things work. Because of people’s lack of knowledge, it is easy for them to accept what the movies or pictures present to them. Therefore, there are many misconceptions in astronomy of how things really work out in the universe. In Neil Comens’ book, Heavenly Errors, he pinpoints over 1600 misconceptions! For example, many people have several different theories of how the moon changes shape every night or why the stars twinkle in the night time sky.
The first person to ever observe the Milky Way was Greek philosopher, Democritus, who said the galaxy may consist of distant stars. In 1610, Galileo Galilei used a telescope to study the Milky Way and came to the conclusion that it was composed of billions and billions of faint stars. Then, in 1750, Thomas Wright c...
Thanks to his studies, especially after the translation of Kitâb al-Manâzir (The Book of Optics), many scholars and scientists were inspired. Later European scholars were able take what he had discovered and further our knowledge about cameras and optics in general. Alhazen’s creation of the pinhole camera is the reason why cameras and other important inventions were created, such as eye-glasses, magnifying glasses and telescopes were created, as scholars and scientists knew how images are reflected in our eyes. He especially influenced Isaac Ne...
A telescope is a device used to magnify distant objects. Telescopes can be used to look at things on earth or at objects in space. The telescopes for use on the earth are known as terrestrial telescopes and the telescopes for looking into space are known as astronomical telescopes.
The earliest known telescope was created by Hans Lippershey in 1608. Others have claimed to have made the discovery of telescope but according to documents, he is the earliest who has applied for the patent. The telescope had an convex objective lens and a concave eyepiece.
In 1609 the telescope was invented and Galileo began making his own lenses for better telescopes and then started looking at the sky. In December and January (1609-1610) it is said that he made more discoveries that changed the world that anyone has made before or since. He wrote a book called the “Starry Messenger”, and said that there were mountains on the moon, the Milky Way was made up of many stars, and there were small bodies in orbit around Jupiter. He used his mathematical skills to calculate the motions of these bodies around Jupiter. In 1610 he started looking at Saturn and discovered the rings, and the phases of Saturn (just like our moon’s phases).
