  • 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.

  • The angular parameters of celestial mechanics !

    Define an Hour Circle. Its a bit tricky to define some astronomical parameters and not run into innocent looking misrepresentations of facts. One needs to cool his amber more times than there are parameters, then one gets a feel where and how to begin and give a good description. Hour Circle is a GREAT Circle,…
