This blog post is completely unrelated to everything we have written so far haha but I recently saw a talk of physics professor Brian Greene about string theory and I don't know if it was the subject or if it was just him presenting it in such an interesting way but I got hooked. Sharing the knowledge here in case anyone would find it interesting. If I was about to study I might have considered studying physics now :)
First of all, here is the video:
First of all, short about the string theory and the background of it all.
The name String theory comes from the way physicists imagine the smallest particles. Earlier, particle physics has described the particles as point like particles and in string theory these have been replaced by one-dimensional objects called strings.
String theory tries to solve the big problem of uniting two other theories; quantum mechanics and the general theory of relativity. Quantum mechanics is used to describe three of the four natural forces in the universe; the electro magnetic force as well as the strong and weak nuclear force. On the other hand, the theory of general relativity describes the fourth force which is gravity. Physicists have for 100 years tried to combine these two.
The hope of physicists is to find the so called Theory of Everything which is a single, all-encompassing theory of physics that fully explains and links together all physical aspects of the universe.
