  • Primary aberration, a lecture in optics.

    Primary aberration, a lecture in optics.

    Lecture-II; delivered on 27-1-2017 In our Lecture-I  we discussed the phenomena of aberrations that arise because of a discrepancy of a first order theory and the 3rd order theory as depicted by the Maclaurin series; where we saw that first order theory represents the so called paraxial optical systems. Please have a look of the linked…

    Aberrations, a lecture in optics.

    Optics series Lecture — I Optical Aberrations delivered on 24 – 1 – 2017 — all optics series lectures can be accessed here.  This lecture has been delivered in one of the honors class that I am teaching this semester. You will do really well to read the linked article on Optical path and Fermat’s principle…

  • A c++ code for calculating pi value.

    A c++ code for calculating pi value.

    Finally I am successful in calculating pi value — less than 0.3% error, by using random number generation. Although my computer needs some fixation on its compiler or path definition etc, there are very good online compilers which helps in testing and running c++ codes: try the given link. OUTPUT Computing the value of pi…

  • Schrodinger Equation; Concepts and Problems in Quantum Mechanics.

    A long and technical discourse on Quantum Wave Function. A 64 slide presentation styled discourse on the Quantum Wave Function. It consists of detailed solution of 5 important and interesting problems, apart from a threadbare discussion of the concepts.

  • 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.…
