  • LIGO in India? You must be kidding …

    I was pleasantly surprised that this experiment is slated to come up in India, yes, with a whopping 250 million dollars investment into science in India is perhaps the only 2nd instance of massive science euphoria. And they are both directly or immediately so, in my field of research, although the first one INO isn’t…

  • 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…

    The Basics Of Physics — Is Gravity Amenable To Quantization?

    The basics of Physics — is Gravity amenable to Quantization? This is a very detailed and long article, but written in a very simple language, as it seems to me, describing such concepts as; the basis of expectations of “Quantization of Gravity with other forces” which is colloquially known as Einstein’s dream of GUT –…
