The Mysteries of The Apple

Isaac Newton was an ordinary young man, who liked the idea of Science and discovering new things. It was a normal day, when he had nothing to do, so he went to his garden and leaned by the apple tree that he always used for thinking about his life and the wonders of science. He called it Alice. The weather was boring, as London always was cold and rainy. For the next hour or so, Isaac kept thinking and brainstorming about his previous question about the Earth. He asked himself why the earth moves faster around the sun than around an eclipse. He had his book by his side, so he just layed there for about three hours reading. He was very interested in the book, but somehow, he fell asleep in the middle of it.
He opened his eyes, noticing that it was noon already, so he just carried on observing the sky, as the sun disappeared into the darkness and the moon popped up. When he was getting ready to go back inside and have dinner, an amazing thing happened. He suddenly felt a sharp pain on his head, and noticed that something hit him. He looked around to see if there was something relevant, and noticed a bright red, big apple by his side. He then looked up, seeing the empty branch on the tree which was above him.
"What made that apple fall?" he asked himself.
"It fell because its stem would no longer hold it to its branch," was his first thought.
But Isaac was not satisfied with this answer. "Why did it fall toward the ground? Why didn't it fall some other way just as well?" he asked.
"All heavy things fall to the ground—but why do they? Because they are heavy. That is not a good reason.
When he had once begun to think about this he did not stop until he had reasoned it all out.
Millions and millions of people had seen apples fall, but it was left for Isaac Newton to ask why they fall. He explained it in this way:—
"Every object draws every other object toward it.
"The more matter an object contains the harder it draws.
"The nearer an object is to another the harder it draws.
"The harder an object draws other objects, the heavier it is said to be.
"The earth is many millions of times heavier than an apple; so it draws the apple toward it millions and millions of times harder than the apple can draw the other way.
[39] "The earth is millions of times heavier than any object near to or upon its surface; so it draws every such object toward it.
"This is why things fall, as we say, toward the earth.
"While we know that every object draws every other object, we cannot know why it does so. We can only give a name to the force that causes this.
"We call that force GRAVITATION.
"It is gravitation that causes the apple to fall.
"It is gravitation that makes things have weight.

"It is gravitation that keeps all things in their proper places."
