  • 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…

  • Ideas that changed our notion about the Universe.

    1. Aristotle Fallacy; A notion that objects need force for their movement. It contradicts the idea of inertia. Newton corrected this by introducing the first law, things continue in their state of motion, a quality called as inertia, without requiring force and the motion changes due to application of force. 2. Earth is flat; that…

  • Whats Light. A small primer.

    A small primer on optical attributes of Light. Manmohan Dash, ( — largely edited, 18-19 January 2014, originally from; Wednesday, March 27, 2013 at 3:58 pm UTC + 05:30 ) Updated Discourse. If you ever seem, to be caught up between: they say light always moves at the same speed-c, they keep on harping, why…

    How to add speeds; Galileo and Einstein won’t agree.

    How to calculate the speed of anything, when their speed becomes closer to the speed-of-light.  This article was originally a comment in the linked article;  Why Nothing Moves Faster Than Light. — In order to correct the comment I have made earlier  ” unless something is completely mass-less in its rest-frame ” I also add the following. This…

  • 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.…
