  • Moment of inertia

    Pretty much all the ideas of moment of inertia is packed in the following: (from the result I = mrr you can integrate or sum this to get more complicated rigid bodies, define from COM etc)

  • What are photons?

    Photons are said to be the quantum (new-Indian-term: प्र-भागी) that carries the energy of unified electromagnetic fields. An unified field is an advance treatment of electric and magnetic fields that are treated “same” because of a great idea of Einstein’s special theory of relativity. Like the equivalence of space-distance and time-intervals, electric field and magnetic…

  • The nature of Physical truth and our approach to find it

    The Unification of fundamental physical interactions is a result of that abstract thinking, and look at it, we are successful because nature nods “agreed”. One example of this unification is is how the electric fields (E) are same as a magnetic field (B) if you recognize that the E, B fields are not fundamental but…

  • Why nothing moves faster than light !!

    There is an interesting discussion on twitter why “nothing can move faster than light”. I could not resist myself from a simple explanation I also think a similar one might have been given by Einstein himself, long time ago, so forgotten by most when they try to explain it. How does something go faster !!…

  • The nature of quantum mechanics.

    When nature takes all the million paths, allowed for the tiny bump or the ball, which includes all the paths in the vicinity of the actuated path (that is, the actual trajectory of the ball seen on TV) all of them cancel each other out. If Path A is the actuated path, then its surrounded…
