Recommended: Isaac Newton's contribution to scientific knowledge
There were many scientist who helped with the early design of the telescope but Isaac Newton is known for inventing the reflecting or reflector telescope in 1668. This telescope was different because Newton used mirrors rather than lens. He used one mirror to capture the image whil the other mirror was used to reflect the image from the first mirror. This invention gave a clearer picture and helped to advance the study of planets, stars and other objects in the solar system. Even with Newton’s reflecting telescope, the earth’s atmosphere was still blocking a lot of light for scientist using the telescopes on the ground. They did not get the best images. To help resolve this problem the Hubble space reflecting telescope was invented in
Shortly after college he began to study optics and the construction of telescopes, and wrote his first book, Optica Promota ^1. In 1663 James went to London where he published Optica Promota, which discussed topics such as lenses, mirrors, reflection and refraction, paralax and transits. Optica Promota also discussed Gregory's most famous invention, the reflective telescope. It later became known and the Gregorian Telescope. However, at the time the telescope was only discussed because the mirror polishers could not polish the mirrors properly, so it was never auctually made untill after Gregory's death. He laso invented the feflective burning mirror. In 1664 James went to Puda, Italy and studied under Stefano degli Angeli in geometry, mechanics, and astronomy. While he was there, the published two more worksVera circuli et hyperbolae in which James showed how to compute logarithms by finding the areas of inscribed parallelograms between a hyperbola and its asymptotes, thus leading to the term "hyperbolic logarithms" in 1667. ^2 And Geometriae para universalis where he attempted to prove that the (little shape thingy that i cant type ...looks like a n mixed with pi) and e are transcendual, unfortunatly, his arguments contained a subtle error which was published in 1668, right before he left Italy for London.
Who has not ever, even if just for a brief moment, looked up at a dark but vividly lit starry night sky and wondered how far those seemingly little lights reach, and if that beauty goes on forever, or if it ends at some point. I believe this question has been pondered by mankind since our creation, and early astronomers are proof of this pondering. Telescopes began as a way for these early astronomers to chart the stars and planets and their movements as they searched for more than what just the naked eye could offer them. In the early 17th century, craftsman began making telescopes, though the tools to invent them had been available for centuries before. Early telescope were called spyglasses and needed improvement. Galileo's Optic Tube, also known as the Galilean telescope is an example of the early creation of refracting telescopes. There were a few different makers and models of refractor telescopes but it was soon discovered they could make a better telescope. With the beginning of the 18th century came the reflecting telescope, which is also called a reflector; an optical telescope that uses either a single curved mirror, or a combination of curved mirrors. There are many types reflecting telescopes: there is the Gregorian telescope, the Cassegrain telescope, and the Ritchey–Chrétien telescope. But today, we are going to be talking about one telescope in particular; "the 200 inch Hale Telescope, which for decades stood as the largest telescope on the planet"(1), from 1948 to 1976. The Hale telescope opened up the skies in ways we never imagined.
Galileo Galilei was born in 1564, and was invested into science. Due to rumors in the year of 1609, about a Dutch who invented a device that zoomed in on distant objects (this was known as a spyglass earlier in the years, now its known as a telescope. He heard that a patent had been requested, but was not granted. There was a lot of value in this because the methods were kept secret, and this could be used in the military for Holland. Due to the rumors, Galilei was soon determined and driven to construct his own spyglass. Within 24 hours, only using his knowledge, experimentation, and pieces of the rumors, and never seeing the actual Dutch spyglass, Galilei soon found himself building a 3-power telescope. With some tweaks, he soon had a 10 power-telescope. From here, he demonstrated this it a Senate, and his salary was raised, and honored with proclamations. This shows how smart Galilei was, being able to construct his own telescope with nothing but his brain.
In 1604, Johannes Kepler published the book Astronomiae Pars Optica. The book has been considered by many to be the basis of all modern optics. In his research, Kepler discovered many of the fundamental principles of optics (Molecular Expressions). He discovered how the eye bends light in order to form an image. He was one of the first people to use a pinhole camera to study how images are formed, and how the camera causes the image to form upside-down. He further discussed inverted images in another book, Dioptrice (Kepler). He also discussed how magnification worked, figuring out how telescopes work. Sadly, Johannes Kepler died in 1630. However, his writings on optics laid the foundation for all the work that would come after him.
It was invented in 1658 by the one and only Christiaan Huygens(source 3). While he was an astronomer he looked at Saturn with his telescope hoping to study
...ld of algebra and physics. His inventions add to his legacy as well, especially the improved telescope. The telescope allowed for many new opportunities for astronomers. His pet door was somewhat revolutionary as well, and it is an invention currently still used by millions today. Newton was an idol of success and proof that hard work and passion equals greatness. He also proved that anything is possible, even with restrictions.
Newton was also involved with telescopes. After his growing interest with light bending, he applied his knowledge of the reflecting and refracting properties of light and invented the first reflective telescopes. Newton's reflective telescopes vastly improve the clarity of images as well as escaping from chromatic abberration. In order to fully understand the concepts and ideas of how a telescopes work, some knowledge of simple optics are required.
In 1990, NASA launched their 12.5-ton Hubble Space Telescope into Earth’s orbit. The telescope was named after the astronomer Edwin Hubble and featured an eight-foot-tall concave mirror with a two-foot-wide hole in the middle and a smaller convex of two-feet-tall. The telescope’s main function was to take light and reflect it off the concave mirror towards the concave mirror which then bounces the light to a focal point, where the image is put together and viewed by the observers on Earth.
The reason the Hubble telescope is so revolutionary is because it is the first telescope in the world to be sent to space (“Hubble Essentials”). Before the Hubble, telescopes had not been able to capture space with such accuracy and precision—the atmosphere was in the way. Atmospheric distortion was the cause of many high functioning telescopes to suddenly cease to work because pockets of air in the atmosphere distorted the telescope images, and even aerospace engineers could not find a solution.
The microscope which is invented and developed by much different scientist overtime is one of the most important tools a scientist especially in the biology and chemistry study can use. It made an impact in how we view life and learn more about the nature of diseases that had plague mankind for years. The microscope is mainly a tool biologist use but it has many uses for those studying chemistry.
The Hubble Telescope is the world’s first space-based optical telescope. The Hubble telescope received its name from American astronomer Dr. Edwin P. Hubble. Dr. Hubble confirmed an ever expanding universe which provided the basic foundation of the Big Bang theory. The first concept of the Hubble telescope came from Lyman Spitzer in 1946, who at that time was a professor and researcher at Yale University. In 1946, Professor Spitzer believed that Earth’s atmosphere blurs and distorts light, and a space orbited telescope would be able to overcome this problem.
He concluded his work on optics by explaining that a refracting lens of a telescope would disperse the light into multiple colors. To prove this, Newton developed his own telescope using mirrors instead of using the traditional telescope lens. This was the first telescope of its kind and is known as the Newtonian
He conducted experiments on sunlight and prisms. He discovered that sunlight was made up of different colors. This lead to his work on reflecting telescopes. At the same time he was working out his ideas of planetary motion. He returned to Cambridge in 1667 and became the a fellow, earned his MA and the following year became the chair of the math department. he then wrote a book on optics. Newton worked cooperatively wiht other scientists such as Robert Hookeand Edmund Halley on planetary motion. But he was later bitter and resentfull not wanting to give other any credit for their contributions to his work. Newton went on to serve in government positions such as a member of Parliament and later as Warden of the Mint. His only words spoken as a member of parliament were "shut the window." He had a mental breakdown of sorts resulting in thoughts of persecutiojn mania later in life.
Over the years, there have been many more important figures in astronomy. One extraordinary astronomer was Galileo Galilei, who invented the first refractor telescope in which light is bent to enlarge an image of the sky (“Galileo Project”). The next great astronomer to follow him was Isaac Newton. Newton had made a great amount of contributions to astronomy during his life. He further proved that the Earth was not the center of the universe and he also invented the Newtonian reflector telescope which is still used today in observatories.
Isaac Newton created the first 'practical' reflector in 1668, which included a small flat diagonal mirror to reflect the light to an eyepiece mounted on the side of the telescope. With time, telescopes became bigger and more sophisticated, and astronomers discovered more stars and galaxies. They were also able to calculate the distance between stars. Most of the large optical telescopes used for research today are reflectors.
