Hi, I'm Faheel Hashmi!

I teach physics. Well, I have taught physics for a good number of years in a well reputed higher education institution until my tenure case was rejected. "Publish or perish" was the mantra of higher education, and I couldn't publish enough ( more on it here). Anyways, I still love to teach, and I hope to continue with it at some level in some way.

Other things I am good at (or am learning (or want to learn)) include quantum mechanics, dofus, agriculture, programming, philosophy, full-stack development, and machine learning.

Skills & Certifications

Teaching

Teaching is one thing that I consider myself good at. It has also been my passion. I have taught for over 12 years in higher academia. The courses that I have taught include quantum mechanics, quantum optics, classical mechanics, electromagnetic theory, atomic physics, mathematical methods, and partial and ordinary differential equations. Apparently my teaching-in-higher-academia-days are over, and the new teacher in me is eager to engage with younger learners.

Programming

Programming is the path that I did not take some twenty years ago, and am presently trying to trace my steps back to it. This might look strange, but I am convinced that it's never too late to start a new beginning. The languages I know include Java, C, C++, Python, HTML, CSS, and JavaScript. My learning projects (mostly copied from the course material) can be found at my GitHub page . Hopefully, it will have some original contributions in coming weeks and months.

Writing

Writing is my third skill. My topics are quantum mechanics, science, science and religion, and subjective and objective reality. The stuff I have written online can be read at HackerNoon and HumSub (in Urdu). My least technical (with almost no mathematics) academic writing is part of an interesting debate that we (I and my collaborators) had with Prof. Vaidman a couple of years ago. Lastly, writing a book on quantum mechanics is my to-do project.

Miscellaneous

The year 2025 is the year of learning and a new beginning. I have got myself the Coursera Plus subscription and am enrolled in a number of interesting courses. The new skills that I have acquired so far are:

Publications

PhD Dissertation

My PhD thesis deals with light propagation in atomic medium. For short pulse regime we show that we can use propagation effects for shaping ultra-short pulses. For long pulses we can have coherent control of the optical response of the medium.
