.. emissions as pulsating and the heavenly bodies or planets as covered with a definite blanket of light.
As I gazed around the sky without the spyglass in hand the sphere of fixed stars appeared to be fairly simple; that is until I magnified Orions belt which I saw too many stars to count. Galileo proclaimed that he saw eighty and depicted an illustration of all of them I feel that it is more difficult to find the constellations when probing the sky with the spyglass as compared to using the naked eye to find the constellation and then magnifying the stars of importance. The spyglass definitely made society during Galileos time aware of stars that they were unconscious to.I wonder why Galileo did not mention the Big Dipper that is located in Ursa Major. It was a test for warriors to decipher between the two stars on the handle that almost appear as one, I imagine that it would be reassuring to the warriors that failed to see that there really is a second star. At first I did not realize that there was a second star in the Big Dipper but after seeing it I was able to recognize the faint glowing star.
When I observed the seven sisters I was not able to see a seventh star as Galileo asserted. Im sure that as Galileo observed the clusters of stars in the sky that he came to the realization that to come to a truth in the number of stars is virtually impossible.The next topic that Galileo created a lot of hype about in his proposal was the discovery of four planets. In hopes of putting astronomy in a more visible place in the public eye, Galileo challenged all astronomers to determine the periods of these new planets. This would definitely not be possible by the use of a conventional low powered telescope; therefore Galileo had an advantage for surviving in the patronage world. Since Galileo made his own telescopes and swiftly distributed them to all prominent and potential charitable individuals his name was automatically connected to the study of the universe. Another reason for his domination, which is not really an act of fairness, is the quality of the telescopes he sold and the quality of the ones that were gifts to royal individuals.
The fact that some individuals did not have the power to observe the marvels that Galileo had only hurt his cause of trying to reform the system of the universe.Its logical to say that the spyglasses he sold were not of superior quality in which to make a serious breakthrough in determining the periods of the Medician Stars. Yet he still made money off selling these spyglasses and monopolized the industry in which all individuals were contributing to his financial and influential growth. He knew that it was only a matter of time after all of the speculation and skepticism that he would prevail, and make a profit in the process. I even states in the footnotes of Albert Van Heldens that in the case of observing the satellites s of Jupiter, it was necessary to have a specialized celestial telescope that magnifies fifteen times or more. I cannot say that I have seen the Medician stars, although I did observe Jupiter.His observations of the satellites of Jupiter seem to be consistent in that they form a straight line and are seen at varying times in different formations. Jupiter was an exemplary model that demonstrates how the moons revolve around the planets much like the moon and earth.
This observation may have upset many of the people that believed in the Copernican system at this time, because now two planets were known to have moons. When reading Sidereus Nuncius I did find that Galileos book was persuasive because of the documentation of his research. At first I completely disagreed about the things he saw with his telescope, but then I realized that it requires an adequate amount of time to make good observations as he had.There are other factors that led me to be skeptical; mostly the weather and the light that obscured my view led me to believe that it was difficult to see anything.
The conditions and environment for viewing the sky were definitely much better during his time than ours. There was no electricity in Galileos time therefore he did not have to deal with what we call today Light pollution, Im sure that smog and air pollution have an effect on visibility and influence the amount of quality viewing time available to amateur astronomers today. Galileo finishes his work declaring that the lack of time prevents him from completing everything, which to me is an indication that he was pressured to get his work done in a short amount of time in fear that someone else would make the discoveries before him. Reading through VanHeldens conclusion I found that the scientific world was very competitive at this time and many scientists were very jealous of Galileos success.The case with Martin Horky of Bohemia, who made false implications about Galileos spyglass and then made a wax impression of it to try and reproduce one better than Galileos, demonstrates this clearly. Keplers statement in his reply to Galileo in Dissertatio cum Nuncio Sidereo can either be the revealing of Galileos hidden agenda to gain publicity on his misrepresented findings or what he was truly pursuing the entire time, which was the truth.
In retrospect, Galileo was simply trying to earn a living doing something that he loved, which was the observation of sciences. He did what he had to do. Had he been more modest about his findings I feel that his ideas and observations would not have had such a violent reaction with society and his fellow scientists, some of which were overcome with jealousy and hatred. It is important to remember that people believe what they want to believe and you should never try to aggressively impose an idea on someone or some group of people.
From a scientific basis I can clearly say that I agree with Galileos work and with his methods of patronage, although I may not like his personality. Science Essays.
