    Solutions to Irodov problems

    Problems In General Physics,  I.E. Irodov Part-I Physical Fundamentals in Mechanics. Chapter 1.1 Kinematics.   10 interesting problems in elementary mechanics This post intends to provide 40 interesting problems in elementary mechanics from IE Irodov, Problems in general physics that I solved in last couple weeks. Note that another 30 problems (additional 12 at hand) which…

  • 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…

  • Nature of photons.

    Also (without any direct theoretical connection, but correlation through reality of nature) 3. Photons are classical only in the sense that we perceive light only when photons are produced in large numbers. So large that the laws of the small do not incur large errors because they are in large numbers. Statistically the errors are…

  • Uncertainty Principle Again.

    2. The object can be a large object, eg say something whose picture you are taking. But as explained above its not the energy of the object (or momentum) which is directly coming into the problem. That would be an added degree of concern if the object is moving with certain velocity, a reason why…

  • Review of Gravity, the movie, discussions.

    A discussion on Space movie Gravity, which I saw recently. I remember one fact, that concerns, Physics, the roughly 50000 miles an hour (correct?) speed of ISS level debris that was coming, it set me thinking, are they violating the Relativistic Laws? For a while, and then I realize its per hour, not second, (that…
