Thanks for watching! Leave your questions in the comments; so that I may answer them in a follow-up video.

Finally found someone who explains step by step. These series are treasure, thank you so much!

Such a fantastic way of explaining quantum mechanics and the mathematics that accompanies it! It's is absolutely gripping!!

[@sengeeran]

excellent display with utmost clarity....thanks

[@physicsdaemon]

Glad you liked it

I remember in my post graduation days I had very hard time while self studying this book and ended up with Landau Lifshitz. For me this book is next to Jackson's Electrodynamics, in terms of difficulty if you're self studying. I am looking forward to your lecture series and this first lecture gives me hope 🙂

[@physicsdaemon]

Thanks, I'll try not to disappoint you 🙂

Very clear and very complete!

[@physicsdaemon]

Thanks! Glad it was helpful.

I tried to absorb as much as I could from this lecture.

Thank you for your efforts

Welcome!

The map ψ -> |ψ> is not _just_ linear: IT'S ACTUALLY THE IDENTITY MAP! So writing |ψ> is completely useless, as you could just write ψ. And then, when one writes |λ> for an/the eigenstate of eigenvalue λ, the map λ -> |λ> ceases to be the identity map and becomes the map associating to an eigenvalue its corresponding eigenvector (when it is unique...). There's no wonder why many mathematicians rightfully cringe at the "bra-ket" notation!
