  • The photon saga.

    5. Photon is a zero mass particle (not a zero rest mass particle) and its deflection in gravitational field, called gravitational lensing is due to two reasons; i. single photon effective mass is due to the definite energy and momentum of the same. ii. multiple photons have non-zero invariant mass, hence they behave like any…

  • Mach’s Principle

    This is called Mach’s principle because Ernst Mach had questioned the validity of associating the rotation to immediate surrounding. Now to visually understand the Mach’s principle Weinberg stood up, in that video, and made a movement which explained how your hands rotate faster or slower. I didn’t understand this well enough so one night I…
