NEWTON

In this adventure, we will visit our good old friend, Newton, whom we seem to be meeting in every section! What luck, I see him now….

"Excuse me Newton, can I ask you some questions about your concept of the universe?"

"Ah yes, the funny hat guy! Ask away, as long as you promise not to steal my ideas, SureYou see many of Newton's observations were not of his own, but rather borrowed from other people. Others still got some credit but Newton was the first to publish them so he is most reputable for his observations. Also of note, Newton was a very arrogant person - he thought he knew everything.)."Well you see I, like others before me, believe the universe is heliocentric. Kepler's laws of planetary motion showed this. Now I, on the other hand, added finesse to his laws of planetary motion, I derived a relationship between two masses and their separation distances. I call this relationship, " The law of Universal Gravitation ".Gravity is experienced between earth and any object and or between any two objects. The difference is that the force of gravity experienced by your hand to your fountain pen is too small to notice. You require one object to have a very large mass to notice anything.

Gravity

"Very interesting Newton. Now may I ask you about your view of God and the universe?"

"Of course. You see, in my view the universe follows a set of laws. Every particle must obey these laws. To me, God is a great engineer who crafted this universe from nothing. He is the creator, founder, maintainer, preserver, and destroyer of this universe. God is above all comprehension, we must respect his creation."

"Thanks for the insight Newton."

"You are welcome. Perhaps next time you could change your hat."

summary

star Newton said that all objects that had mass had a gravitational attraction to one another.

starUnlike most scientists at the time, Newton saw God as the wise creator and caretaker of the universe

starIn this section we were briefly introduced to Newton's Universal Law of Gravitation. This law can be used to calculate the force of gravity between any two objects, regardless of their position in the universe. It is:

starForce of gravity = (6.67x10e-11)(mass 1)(mass 2)/(separations distance)**2

This section also showed to us Newton's philosophy of religion and God. You see before Newton, many scientists were trying to deny the existence of a higher being. Newton however saw God as a watcher and creator of the universe - a revelation of God's beauty. It is important to understand this philosophy regardless of your belief because many scientists tend to share the same view of God and science. This view sometimes influences their work. Our next section will introduce us to some very neat things that happen as a result of planetary motion, so click below on the Time Machine to go back to present time
