Understanding String Theory

Hey Guys, I am back with something interesting. "The string theory".


We all have ability to perceive the beautiful world around us. But our desire to explore the origin of our world and from what this things are made? to get answer of this question numerous scientists have researched about it. getting deep into it we have discovered smaller and smaller particles breaking the earlier limits. String Theory is also a one attempt to get into the depths of smallest fundamental particles. When we go for the higher documentations for reference or see tough explanation we find it too difficult to understand, I have tried to make it simple and also provided the harder way explanation.

So let's start...
Lagrangian describes the motion of an object in a plane w.r.t time. Now take lagrangian of motion of two dimensional entity in Field-World "X", so the action that describes the motion of this entity is basically area of World-Sheet using pull-back metric from ambient Space-Time to World-Sheet of string by using Sum-Over-Paths approach to quantum mechanics. further we can work over this correlation function in two-dimentional field theory and that principle would be observable that would describe scattering amplitudes of string in string theory




No Need to worry, I'll break it down for you.

Here Comes The Breaked-Up Version

Getting back to primary school, we all have studied about substances and their constituents. Let's have some solid substance, let's take a cube of iron, when we cut it into smaller cubes and do it for some thousands or million times we would have molecules of iron. breaking it down more we would get atoms of iron.


and of course, as you know this atom consist of quantum electron cloud moving in unique orbits. And there's a nucleus containing protons and neutrons. Well, this is not the limit they are further made of particles called "quark"
According to the String theory, inside these subatomic particles there are tiny string like structures having random movement. and they are reason for the behaviour and nature of a particle.
We can imagine a string loop like this.       
                                                                            👇👇👇
simplifying the above stuff, inside the quarks and muons and mesons there are such string like particles which vibrate to produce particular particle.

According this hypothesis, these strings determine the behaviour of an particle, and the definition that I gave above shows how to determine their path and energy. simplifying the above content, the probable path of this lagrange is mathematically calculated using some approaches whose reference is given here. I have also attached some video links for more reference.

Lagrangian

Imagine you have a big land piece and you want to build a beautiful mansion there. For this task you have to hire designers, masons, painter and all sort of workers. getting this work done from them is a pretty difficult task. And you suddenly you came across a machine that can do all sort of work alone. This is more or less same in the case of a lagrange The word Lagrangian can refer to a mathematical quantity or a description of a way/method to look at physical events. The Lagrangian method is normally contrasted with the Eulerian method. If you follow the motion of few moving things and devise equations to describe the motion and how the other attributes change along the path, then you are using the Lagrangian method. If you stick to ground and observe these moving things and again devise equations to describe the motion and the changes in the attributes of the moving objects, then you are using the Eulerian method. Like being in a plane and putting rules for its flight, or sitti...

String Theory says we might have at least 10 dimensions!!!

But wait, this isn't only strange thing about it. Quantum physics is weird. Once you say you understand it, you get 5 more reasons to argue it. Same is in case here. the normal model of Quantum mechanics says everything is made up of elementary particles like quark, electrons, protons. String theory says everything is just a string vibrating in its own way. yes, it summates more complexities but it solves many decade old problems. Just look at the standard model which says everything it made up of 12 elementary particles The standard model We have six quarks and six leptons which make up particles. photons bind the electromagnetic waves, gluons are the "glue" that binds up the strong nuclear forces, while W and Z bosons are responsible for weak nuclear forces. As we know there are four fundamental forces Gravity, Electromagnetism, Strong and Weak nuclear forces. Astonishingly scientists aren't able to explain the most famous force-Gravity. And here comes the...
