  • What are Gauge Potential, Whats a “Theory” in Physics?

    Potential was, as said above, is, energy per unit mass or charge. So, we see that, in defining the higher quantity energy or potential (higher therefore closer to action, hence more fundamental or unified) we have to INTEGRATE the lower variable, here, Force, Field or (Any ) 3-vector. This entails therefore arbitrariness into the Physical…

  • A Physicist is a physicist’s way of talking about himself.

    A Physicist is a physicist’s way of talking about himself.

    In my case therefore you see, 0 publications in 2001. The year I joined my PhD, I was learning more about snow-fall, JC Peney and Bus rides. 2002 I have hardly 1 or 2, that was the year when in the later half I was given the privilege of being able to sign for science…

  • Still some gravity !!

    So talking about gravity fondly I have made a remark “Its not gravity that makes you fall”. You would be shocked as if you fell down but its not due to gravity but something else is at work, Am I a Physicist propounding a phantom theory? The actual statement I made is “Its not gravity…

  • Optical Path and Fermat’s Principle.

    Optical Path and Fermat’s Principle.

    Mirror and Fermat’s principle: We can see ourselves in the mirror and take our mirror reflected selfie as a consequence of Fermat’s Principle, the topic of discussion of the blog. … Snell’s Law governs refraction which is adjustment of optical paths in in-homogeneous media because light can no more travel at its speed in free-space.…

  • A Question a Day (series) Q3

    The equation v = a*del_t is sometimes used to find velocity when acceleration and time are known. Another form of this equation is v = v_0 + a*del_t. In this second form of the equation, the function of the term v_0 is to: A. indicate that the equation is valid only for an object that…
