  • Compton effect, Quantum Lecture 3.

    Compton effect, Quantum Lecture 3.

    As we have mentioned earlier, we would be discussing a few experiments that elucidates the nature of the new theory based on the ideas of quantization and wave-particle duality. This lecture will be an addition to the phenomenon of photoelectric effect that we discussed in our last lecture, as an example of how a classical…

  • 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…

  • What happens when squirrels do not move.

    What happens when squirrels do not move.

    Stationary state and squirrels ! Okay so the squirrel isn’t moving around so much, giving a fuzzy image. We can call the instant during which the squirrel wasn’t moving akin to a “gross” stationary state. But why is the railing of window fuzzy? It isn’t moving ! Diffraction. Due to diffraction enough light is coming…

  • 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…

  • What happens when cows move rapidly !

    What happens when cows move rapidly !

    Cows not moving and moving fast. How does this difference impact the image in a modern digital camera? Honestly I haven’t checked it with old day manual camera neither do I remember what impact motion brings into mages taken by such, eg does anyone remember when he/she took a picture of a friend standing in…
