Galileo Galilei also was in Astronomy and was known for Projectile Motion, Galileo was a confirmed Copernican and given to the concept of circular motion. Galileo 's 'facts ' differed from the traditional data of astronomy in that they were derived from qualitative telescopic observations. Some of the observation data that he collected from the telescope was that the phases of Venus were inexplicable in terms of Ptolemaic cosmology; Ptolemaic scheme no longer viable and the satellites of Jupiter, moving with, and approximately in the same plane as the planet, suggested more than one center of rotation in the solar system and, by analogy, the earth 's rotation around the sun. In his later theory (1632), no force is necessary to keep a body moving on a level (frictionless) plane; a body, as such, has no inclination to move or remain at rest, it is indifferent. Thus, if a body is indifferent to motion, no mover is required to sustain movement once a
Sir Issac Newton and Galileo Galilei were two of the most leading scientist of 17th century. Unfortunately, the two were never able to work together as Issac Newton was born the same year Galileo died, 1642. One thing is for sure, between the two there was a storm of scientific revolution under way. I will begin with the earlier revelations of Galileo. Considered the father of modern science, Galileo made major contributions to the fields of physics, astronomy, cosmology, mathematics and philosophy.
Later on he presented his findings to the Royal Society, where Astronomer Royal Nevil Maskelyne revealed that it actually had a planet like orbit, and did not seem to possess a tail like a comet would. It was the first new planet to be discovered by scientists. When it finally came time to name the planet, Herschel suggested naming the planet after his patron, King George III, in which it would have translated to Georgium Sidus, or George’s Star. Outside the limits of England, most people did not appreciate that suggestion. Other names suggested included his own last name, and ironically the name Neptune.
In the pre-Copernican era, geocentrism was the paradigm for astronomers and philosophers. There were some thinkers, such as Aristarchus and Oresme, prior to Copernicus who advocated for heliocentrism or other models. However, the majority of philosophers and scientists held on to the physics and models of Plato, Aristotle, and Ptolemy. Nicholas Copernicus caused the paradigm shift from the idea that the Earth is stationary and central, to the idea that the Earth rotates and revolves around the sun. In De Revolutionibus Orbium Caelestium, Copernicus explains his stance on the shapes, movements, sizes, and positions of celestial objects (Danielson 104).
The people of medieval Europe also believed each sphere has its own solar system with stars, planets, and sun, and they all orbit around Earth. It wasn’t until Copernicus in the sixteenth century that the idea of the earth revolving around the sun was considered and it wasn’t until the eighteenth century that people started to think that the universe was “infinite in time and space.”( pg.2) According to Christian the modern temporal scales are as intimidating
Firstly, Copernicus began to doubt the way that Ptolemy had organized the universe. Also, Ptolemy was an astronomer. Ptolemy 's arrangement of the universe had unanswered questions; which, included: why planets could sometimes look like they were changing directions. Next, he created the Heliocentric Theory. Which, states that the sun is the center of the universe.
Did you know who first discover that there’s more to the universe than just the milky way and who laid the foundation of the big bang? That was Edwin Hubble. Edwin Hubble uses all of the IB profiles throughout his entire life, but the one IB profiles that stand out and that IB profile was that he was a risk-taker. Edwin Hubble was born on November 10, 1898 in Marshfield, MIssouri. His love for astronomy started when he was 7 and his grandfather (was an enthusiastic amateur astronomer) showed Edwin his telescope and he asks to keep looking at the sky instead of having a birthday party .
At the time (1600 hundredths) the main astronomical theory was developed by Aristotle, and he believed that the Earth was the centre of the solar system, and that different objects with larger mass would fall at different rates. Galileo didn’t believe this, and as a result started to prove Aristotle’s theories wrong, and Copernicus’ right. DIFFICULTIES AND
Kepler’s third law modified by Newton is T^2(Me+Mm)= D^3. T is the orbital period in years and D is the distance between the Earth and Moon in AU. Me is the Mass of the Earth and Mm is the mass of the moon. Then I set Me+Mm=Mt. Mt is the total mass of the Earth and Moon combined.
The problems they were not able to solve were answered by a supernatural explanation. Another example of religious hinderance was shown in the Muslim community. Tyson talks about the exponential rate of scientific developments in places such as Baghdad in the early 12th century. It was a breeding ground for inventors, scientists, theorists, and mathematicians. However, a Muslim man, Iman Hamid al-Ghazali, declared that mathematics was the work of the devil.
