Galileo’s Telescope
The narrative on Galileo’s telescope is nicely recognized and retold many times. It absolutely was inside July of 1609 that Galileo heard of news that some Dutch opticians had come up with some kind of optical instrument that can amplify objects and produced them nearer. The news was by then really well-known when Galileo got hold of it.
The Venetian government was alert to it and had intention to buy more than the instrument from a foreigner until Galileo’s friend Paolo Sarpi advised them to delay buying as he was positive that Galileo could outdo it. Galileo was a great experimentalist and then he dedicated himself to enhance the instrument and he came up with a more powerful instrument that had greater than prior to magnifying power. This was done through his understanding of improved magnification by means of a weak convex lens and a strong concave lens. Up to that time no optician was able to manufacture a much higher magnification than three and he has to grind the lenses himself.
It had been then in the autumn of 1609 and as curiosity taken more than him, he directed the refined instrument towards the sky. He was then astounded by the power from the latest instrument. From the observation, he figured out that the earth was not the center in the universe. It absolutely was opposite to what the bible was about at that times along with the church stated publicly that Galileo was wrong. Galileo disputed that the interpreter on the bible may be wrong but he was accused of heresy. Though he was discovered innocent, he was banned from spreading the Copernican belief system.
Copernican belief system was the doctrine that Earth isn’t the center of the universe but revolve round the sun. Galileo went on to apply his information from the refined instrument to other areas specifically the study on Jupiter and the ocean’s tides. He continued with the Copernican belief system even though he was not allowed to teach. As a result he was kept under house arrest until his demise.
It was from there that he made even far more discoveries. The spots on the surface from the sun, rings that surround Saturn and the number of phases that Venus goes by way of had been because of his observations. All these were published in “The Starry Messenger” in 1610. That caused quite a stir back then just to visualize that the earth was round and not flat as thought earlier.
Galileo was the early contributor to the sophisticated, modern telescope that we recognized nowadays. Without his curiosity and observations, our familiarity and understanding from the modern universe will not be as comprehensive.
