Galileo Galilei was an Italian physicist, mathematician, astronomer, and philosopher. Born on February 15, 1564, Galileo was most known for his feats in astronomy and in advancing the scientific revolution of the 16th century. He was a big supporter of Copernican theory which states the sun is the center of the solar system. This theory was revolutionary and contradicted the previously considered correct theory of the time. Thus Galileo was criticized heavily by the church for his beliefs. Galileo has also written many books and articles
The device was a success, and Galileo earned quite a profit from selling the device. In 1606, to help sell the device, Galileo published a book called “Le operation del compass geometric e militate.” He would sell the book alongside each compass that he made. The book described over 40 operations that could be calculated by the device. Galileo’s device also had quite the longevity of use. He invented the device at the end of the 16th century and was still the instrument of choice until the nineteenth century when slide rules became more prevalent. Galileo’s hardest problem he had to overcome with making the sector was not in the creation of the device, but other people trying to claim it as their own. One of his student’s even tried to claim ownership by publishing a manual on how to use the
He was thinking about measuring the temperature of a body somehow. He made the thermoscope by getting a glass with wine. Second, an open tune connected to a glass bulb. That was how simple it was. How his experiment worked, he put his hand on the glass bulb in order to heat the air in side of it. After he put his hand heated the air, the air expands into the tube to the glass of wine. He took his hand away from the bulb to cool it down again. He found that the air came back to the bulb and the wine came into the tube. Galileo found that the thermoscope was stable at that moment. After he found at the stable moment, he marked it. However, he asked a patient to heat the thermoscope. Again the air expanded to the glass. After the air had been expanded, the patient stopped heating the bulb. At that moment while the air came to the bulb and the wine had going up the tube, it past the stabled moment that Galileo marked. He knew that there were something happened. So He was been able to know if the temperature was higher or lower for someone by his
