About Us

I try to teach difficult concepts of Physics and Mathematics in a simple manner and make you fall in love with these subjects.

Keep visitors coming back for more fun, intuitive and counter-intuitive concepts of Physics and Mathematics.

I am currently a high school student with a great appetite in learning concepts of physics and explaining them to others. I try to deliver the concepts of physics in a lucid language with application of simple mathematics.

I also have a YouTube channel (Cosmos Unveiled) where I share with you the concepts of physics.

What is spin in quantum mechanics?

Quantum mechanical spin is basically intrinsic angular momentum which every elementary particle and composite particle possesses. There are two terms to be explained. First- intrinsic. Intrinsic property is a property which the object referred to possesses by itself, it is inherent where as an extrinsic property is something which is not inherent. For instance, mass is an intrinsic property whereas weight is an extrinsic property. Just like mass, charge and spin are also intrinsic properties. Second term to explain is angular momentum. So, what is momentum? By the term momentum, we simply mean linear momentum which is something an object possesses when it moves along a straight line. Linear momentum = mass * velocity, or simply, p = mv Formula of linear momentum Note: those arrows signify that they are vectors Angular momentum is something which an object possesses when it spins on its axis or around any object. Angular momentum = mass * tangential velocity * radius of rotation, o...

What does the standard model of particle physics actually mean?

We all know that matter is composed of molecules which can be further divided into atoms. Again, we can further divide atoms into neutrons, protons and electrons. But are they elementary particles? No, they are not. Electron is an elementary particle, but proton and neutron are not. They can be divided into much smaller particles called quarks. . So, now the question might arise that are electrons and quarks the only elementary particles present in the universe? Again the answer is no. That is where the standard model comes into action. Now the question might arise: What is this standard model thing? Well, standard model is a well established theory of particle physics which describes three of the four known fundamental forces of nature, namely: the electro-magnetic force, the strong nuclear force and the weak nuclear force. It unfortunately does not explain the gravitational force. The standard model is basically an arrangement of all the known elementary particles and mediator p...
