Einstein's General Relativity and Field Equations

  In 1907, Albert Einstein had, what he regarded as the "happiest thought of his life". He imagined a man falling from the top of a house - that shocks you? 😂. Yeah, that was all that is needed for him, to instigate this remarkable insight about "gravity". Isaac Newton did work on gravity too but he only calculated the strength but does not know exactly how gravity works or pulls its force. So, Einstein thought that a man falling from the top of the house will feel weightless i.e. the man won't feel his own weight. That, tells Einstein that gravity have to with motion. He thought about this for 8 years and finally, he was able to come about the remarkable theory of General relativity, in 1915, which explains how gravity really works. With the help of some of his mathematician friends, he was able to describe this with some elegant equations. Thus, the Einstein Fields Equation. Okay, let's get technical a little bit ... General Relativity tells us that

Why Science Works

Science is undoubtedly the greatest weapon the human race has ever had. If you have problem with admitting that fact,  I suppose you should wonder how we came about your smartphone or the laptop in front of you or how we come about the internet. Frankly, those are even just a very little out of many things science has thrown our way.  Science has been here for ages, as far back as the days of Aristotle. It studies everything that is, giving us answers to most of the instinctive - due to our inherent curiosity - questions that comes to our minds as we try to understand every thing or phenomena that exist. And it does that, by describing the nature or behavior of every thing or phenomena using natural laws and theories.  Richard Feynman made that statement in one of his lectures. However, I have personally seen people, being skeptic or far worse, being kind of cynic about science, despite its obvious great impact in the human society at large. Such individuals hold  notions like science
