Leaving our Cradle
Part - 2

In the earlier part of the series we discussed the beginnings of the Rockets and some early pioneers like Tsiolkovsky, Goddard and Oberth. We continue exactly where we left off, about the new refined rockets and the arch enemy of a Rocket; Gravity.
So what is this gravity? And how does it affect us? We can’t see it but we have felt it every single moment from the time we were born, it keeps our feet planted firmly on the Earth and prevents our precious Atmosphere from dissipating away into Space. Now to understand the force of gravity in depth one might attempt to seek out a true giant of science; Sir Isaac Newton. For any mildly educated person, the very mention of the word gravity brings back a picture of Newton sitting under a tree and an Apple falling on top of him, igniting his curiosity about Gravity and the rest as they say is history.
Newton considers gravity as he observes the moon and falling apple peter lloyd
Although in some versions of the story, he merely saw an apple fall down, Nevertheless we owe our first attempt to understanding Gravity to the juicy fruit most of us relish. Newton started working on developing the laws of Gravity or the laws of attraction between two bodies in the Universe; He has stated detailed findings in his published work Principia (the book by Sir Isaac Newton).
