Science Ecstasy

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

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 am

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

The basic idea behind Feynman's sum-over-paths (or sum-over-histories) approach is as follows: Assume that a particle can travel between two points A and B by a - possibly infinite - number of different paths. Each one of these paths will have a certain probability associated with it. In quantum mechanical terms, these probabilities are encoded in the wavefunction that describes the particle, which assigns to each possible path a different probability amplitude ; the square modulus of this amplitude gives the corresponding probability.  The crucial point is that these different amplitudes have a wavelike nature, and as they spread through space they interfere with each other, their respective wave patterns either reinforcing or canceling each other out at various points. And if you sum over all the amplitudes of all the different paths, i.e. you sum-over-histories, then the different amplitudes will reinforce or cancel each other in such a way that the only path that survives this

Dr.E C G Sudarshan was an Indian born theoretical physicist and professor at University of Texas . He is credited for several contribution in physics, out of which most renowned is discovery of "Tachyons". He is well known for is incredible research in field of Optical coherence, sudarshan-glauber representation, V-A theory, open quantum system, Quantum zeno effect. he has also won numerous awards including Padma Bhushan, Padma Vibhushan, TWAS prize, Bose medal, C.V.Raman award and ICTP Dirac Award. He also has notable contributions in relation between West-East, and religion. He challenged the "theory of relativity" by Albert Einstien, for existence of tachyons.

Hey friends, I'm back with an interesting topic " QUANTUM MECHANICS " . Not many people know about it so I thought it would be a good topic to start with. Basically,  QUANTUM MECHANICS is a branch of physics that deals with some of the most argued and discussed problems and studies them. It mathematically proves and describes the motion and interaction of sub-atomic particles, wave particle duality, uncertainty principle, and correspondence principle. so let's start, As you read, you might be thinking its a very rare stuff, but it's too common in our life (Even though, classical mechanics deals with all our day to day needs) and so you may not recall it on your finger tips. Have you ever teased a cat with laser? yes that's a simple example of Quantum Mechanics . Actually laser is  a stream of hyper-focused, nanoscopic, physical reactions ('Sounds geeky'). Yet there are many others too. In fact without quantum science, sun would have been blaste
