Galileo And Stars
I feel that the motivation of Galileo’s pursuits in Astronomy and stargazing
was driven by his desire to be financially successful. Galileo was an extremely
ambitious and clearly independent individual whose methods of generating
scientific data epitomizes a survival of the fittest like struggle between all
of the prominent scientists of his time. During Galileo\'s life there was no gray
area of wealth like the middle class of today, and therefore you were either
rich or poor. In Science and Patronage published by Westfall, the word
friend’s connotation back then was not one of caring for another person and
mutual support but rather defined in a financial type way of using one’s
connections to better one’s self. There was patronage inside of patronage;
therefore Galileo did not always see what he claimed to have seen, his
associates might have though. Since patronage was the way of the world at this
time as Galileo knew it made no sense for someone to swim against the current,
for they would simply become tired and unsuccessful. Because of Galileo\'s
position as a patron to the prince, many of his disciples were patrons to

Galileo himself thus providing him data and insightful knowledge. Galileo in
turn allowed the use of his name as a referral to help his disciples out.

Surprisingly Galileo had only worked as a patron for those, which gave him
enough money or got persuaded into his over exaggerated descriptions of what the
moon really looked like. Galileo did not go into depth with many of the things
he saw, instead he attempted to describe everything he saw vaguely in order to
make sure he got credit for seeing it first. I feel that it is important to
document your discoveries as Galileo had not only to get credit for seeing it
first but to create a larger body of information that can be collaborated on
amongst all of the people. It appears that as he wrote Sidereus Nuncius that he
wasn’t even quite sure of all his findings and mostly improvised through his
work. I am doubtful that the princes he served were even able to see what

Galileo claimed in Sidereus Nuncius at least in our day and time it seems
difficult to get a clear image of the heavens because of light pollution and
possibly air pollution such as smog and other industrial chemicals. Although

Galileo’s descriptions of the moon were sometimes very accurate I did not see
exactly what he did, which could be a result of the moon’s surface changing
through time. For instance, the circular orb located near the center of the moon
at half moon was not visible to me during my observations. Of the more important
facts in Galileo’s discourse, I feel that his deduction that the moon is not
perfectly spherical and smooth as the Pythagoreans had believed, rather
mountainous with many prominence and depressions very much like the textured
landscape of earth. Galileo supports these ideas in a logical manner and
illustrates them in his observations when the moon is in its different phases.

He claims that the dark regions of the moon are shadows cast by the sun. Another
detail about the moon that was made more visible to me by the telescope is the
circular outline around that moon, even in the dark region, that separates the
body of the moon from the ether, which is a term Galileo uses for the rest of
the outer space. During this time there was also much debate about the source of
the moon’s illumination. "Some have said that it is the intrinsic and
natural brightness of the moon herself; others that it is imparted to it by

Venus, or by all the stars; and yet others have said that it is imparted by the
sun who penetrates the Moon’s vast mass with his rays". A good point that
supports the moon reflects light from the sun is the fact that during an eclipse
the moon does not retain its brilliant illumination. Galileo relates this to the
way earth has twilight in the morning and evening when the solar rays falling
upon the earth illuminate depending upon our proximity. I feel that Galileo
appears to be too strong-minded when expressing his ideas as he rejects the idea
of the moon being illuminated by light imparted by Venus. Galileo was the
pioneer of the idea that light is reflected by all of the heavenly bodies. He
proposed that the moon is reflection light to earth, which originates from the
sun and we (people on earth) are reflecting that
