History of Astronomy

This weekend’s reading included a brief summary of some the work and adversity that some famous astronomers went through in their work.  Copernicus was the first to oppose the idea that the earth was not the center of the universe but rather that it revolved around the sun with the other planets.  I am not surprised that most people during that time period did not believe in his theory because it challenged a long-standing belief of the people of the time.  Kepler and Tycho studied mars and the “Perfect solids.”  After eight years Kepler realized that mars and the other planets do not travel in perfect circles around the sun.  Finally, Galileo also defended Copernicus’ initial claim and proved that the planets revolve around the sun.



I found many of the concepts regarding numbers on last night’s reading interesting.  The patterns that numbers are commonly repeated in, for example 1, 3, 6, and 10 being commonly expressed in triangles interested me compared to numbers like 2, 3, 5, 7, 11 and 13 which are prime and are not commonly occurring.  This reading also taught me more about the history of math.  I did not realize that the Greeks were so involved and advanced in Mathematics.  The things that numbers can do, for example discover a type of matter that was without any type of evidence was also something I learned in this reading.  Overall, last night’s reading allowed me to view numbers differently than I previously had by exposing some occurrences and patterns that numbers have.
