  • Four-vectors and conservation laws in relativity

    Four-vectors and conservation laws in relativity

    This lecture was delivered to the final year honors class of 3 year science degree students on 21 November 2017 as part of the Classical Dynamics paper. In this lecture we will discuss some of the important tools of relativistic mechanics. We will discuss the idea of proper-time, 4-velocity, 4-acceleration, 4-momentum, 4-force and related conservation…

  • Waves, particles and Einstein !

    Waves, particles and Einstein !

    Waves are something that have no mass and move at the maximum speed, mass m = 0. speed c = 1. So whats their momentum? p = m.v = 0? Right? No. For pure waves; momentum does not come from mass. It comes only from motion. (pure wave; they do not have mass) For matter…

  • Simple explanation of OPERA Anomaly of FLT

    Simple explanation of OPERA Anomaly of FLT

    Simple explanation of OPERA Anomaly of FLT I just wrote two tweets, one of which, is a concise explanation of OPERA anomaly of Faster than Light neutrinos. (FLT neutrino). Einstein’s Relativity Theory would be invalidated if neutrinos move faster than the photons, which is what OPERA experiment suspected it obtained, but Quantum Mechanics Uncertainty relations…

  • An important lesson of Relativity.

    An insight of why time and space are equivalents or unified in Relativity. Because its time which makes it possible for someone to crawl from x point to a y point, you can’t simultaneously move bifurcated, into two orthogonal axes. Time mediates, hence its the time axis that mixes with all of the space axis,…

  • Equivalence from simple notions of Geometry ? Yes.

    Now it may also be related that light bends in a denser media compared to a rarer media because an additional rotational force is working. In other words, the definition of straight line has to change in the medium, that is of different density, because path of light is changing. Light is the guy who…
