Galileo telescope essay

Philosophically, Galileo has been used to exemplify many different themes, usually as a side bar to what the particular writer wished to make the hallmark of the scientific revolution or the nature of good science.

His projected Fifth Day would have treated the grand principle of the power of matter in motion due to impact. He does this all by reducing the problems of matter to problems of how a lever and a balance function. More recent historical research has followed contemporary intellectual fashion and shifted foci bringing new dimensions to our understanding of Galileo by studying his rhetoric MossFeldhaySpranzithe power structures of his social milieu Biagioli, his personal quest for acknowledgment Shea and Artigas and more generally has emphasized the larger social and cultural history, specifically the court and papal culture, in which Galileo functioned RedondiBiagioli, Heilbron The Starry Messenger, which describes his early telescopic discoveries, was published in The most convenient source for information on the general development of the telescope is Henry King, The History of the Telescope London: But Bellarmine held that the planetary theories of Ptolemy and Copernicus and presumably Tycho Brahe were only hypotheses and due to their mathematical, purely calculatory character were not susceptible to physical proof.

Protestant Reformation vs Scientific Revolution

In he became a member of what is perhaps the first scientific society, the Academia dei Lincei. Though this latter hypothesis has not found many willing supporters. He applied and was turned down for a position in Bologna, but a few years later inwith the help of Clavius and del Monte, he was appointed to the chair of mathematics in Pisa.

For Aristotle, sublunary or terrestrial matter is of four kinds [earth, air, water, and fire] and has two forms, heavy and light, which by nature are different principles of natural motion, down and up.

The objective was mounted on a building or pole by means of a ball-joint and aimed by means of a string; the image was found by trial and error; and the compound eyepiece field lens and ocularon a little stand, was then positioned to receive the image cast by the objective. Feltrinelli;translated by S.

Specifically, he had been charged with teaching and defending the Copernican doctrine that holds that the Sun is at the center of the universe and that the earth moves. Then, he says, join the bodies together.

Galileo had addressed this problem inwhen he wrote his Letter to Castelli which was transformed into the Letter to the Grand Duchess Christina.

What Galileo achieved in revolutionizing physics was to show how observation, careful measurement, and attention to the structure of a given event—all led to an appreciation of hidden causes that ultimately expressed the pervasive mathematical unity of all nature.

The Vatican warned him that formal charges were would be pressed unless he abandoned his ideas that Copernicus was correct and that the Roman Catholic Church was wrong. He calls it the force of percussion, which deals with two bodies interacting.

However, Galileo apparently discussed more unconventional forms of astronomy and natural philosophy in a public lecture he gave in connection with the appearance of a New Star now known as 'Kepler's supernova' in There are any number of ways to argue for some sort of instrumentalism.

The success with which he applied this technique to the analysis of motion opened the way for modern mathematical and experimental physics. These observations played a very important role on the development of astronomy. Van Fraassen, Bas C.

In the end, Galileo had no choice but to repent and confess that he had gone too far. In Florence he continued his work on motion and on mechanics, and began to get involved in disputes about Copernicanism.

As early asin his Dioptrice, Johannes Kepler had shown that a telescope could also be made by combining a convex objective and a convex ocular. The glass was full of little bubbles and had a greenish tinge caused by the iron content of the glass ; the shape of the lenses was reasonable good near their centers but poor near the periphery hence the restricted aperture ; the polish was rather poor.

Imagine Aristotle at the top of the leaning tower of Pisa, dropping off two cannonballs, one twice as heavy as the other. Craftsmen in Venice began making small disks of glass, convex on both sides, that could be worn in a frame--spectacles.

Shortly afterwards the Inquisition banned its sale, and Galileo was ordered to Rome for trial. Except for the inclined plane, time is not a property of the action of simple machines that one would normally attend to. Galileo returned to Florence and continued work on his book, but now he gave more emphasis to mathematical arguments rather than to experimental or physical arguments—as the Pope wished.

Galileo discovered many things: His Scientific Biography, Chicago: Wishing however, to remove from the minds of your Eminences and all faithful Christians this vehement suspicion reasonably conceived against me, I abjure with a sincere heart and unfeigned faith, I curse and detest the said errors and heresies, and generally all and every error, heresy, and sect contrary to the Holy Catholic Church.

The Spyglass and the Astronomer: Seeing Galileo in Perspective

So in cases where it was known that science had achieved a true result, the Bible ought to be interpreted in such a way that makes it compatible with this truth. In each of these fields, Galileo has made a significant or seminal contribution.

Since for astronomical observations an inverted image is no problem, the advantages of what became known as the astronomical telescope led to its general acceptance in the astronomical community by the middle of the century. Galileo argues that the motion of the earth diurnal and axial is the only conceivable or maybe plausible physical cause for the reciprocal regular motion of the tides.

To Aristotleans the world was the center of the universe and that it was perfect. People have looked to the universe to determine physical location, gain spiritual direction and to track time.Galileo used a refracting telescope to view the moon and stars back in the s.

The refracting telescope consists of an objective lens and an eyepiece (Falk, ). On the refracting telescope the big convex lens between the object and the telescope is the objective lens.

Galileo shows the public his new invention - the telescope. Everybody is excited. Galileo gets an increase in salary.

Galileo Galilei

But he is immersed in his own thoughts. Any scientific discovery has a "double" meaning. For the uninitiated, this is just a telescope, and has just practical benefits. This telescope is known as the Hubble telescope and, as ofit is the largest orbiting telescope.

It cost around $ billion to build and can see all the way to the far ends of the universe. Galileo’s Telescope justly credits the nature of Galileo’s achievement and willingness to place himself at the center of an unfolding controversy, at great personal cost.

At the same time, it. Galileo states that he solved the problem of the construction of a telescope the first night after his return to Padua from Venice and made his first telescope the next day by fitting a convex lens in one extremity of a leaden tube and a concave lens in the other one.

Astronomy from Ptolemy to Galileo Essay Sample It has been said that Astronomy has always been the first science to develop in all civilizations. This is not surprising seeing how the sun, moon and stars are such an ever present part of our daily lives.
