  • Mach’s Principle

    This is called Mach’s principle because Ernst Mach had questioned the validity of associating the rotation to immediate surrounding. Now to visually understand the Mach’s principle Weinberg stood up, in that video, and made a movement which explained how your hands rotate faster or slower. I didn’t understand this well enough so one night I…

  • Heisenberg’s Uncertainty Principle from a new angle

    Heisenberg’s Uncertainty Principle from wave-particle duality. The wave-particle duality states that any mechanical object can exhibit both wave and particle behavior and the complementarity priniciple states that they can not both be observed simultaneously. That is the wave and teh particle nature are only exclusive ly observed given a specific time or time window, the…

  • The economic myopia of India and how it affects our resolve for education

    I was taking a little time off and I find that I was thinking more of economy, so it is more like if you trigger your mind to take up on what is brewing inside you may find more than you already said. Quantum Mechanics, you can not completely cut any branch off it’s stem,…

    a simple calculation for earth spin projected onto sun-earth orbit plane.

    Here is the earth-around-sun and earth-spin situation: Earth rotates around sun in a tilt of 23.5 degrees and earth rotates around itself with spin S. SO S is 84% along sun’s vertical and 16% along sun’s horizontal;
