Regarding notation, have you tried this for rendering latex? I gave it a try and it seems to work quite well.

rahul,

I forgot to mention Feynman's Dirac memorial lecture which talks a bit about the half angle formula and relates it to the plate trick. I was lucky enough to attend that lecture and see the plate trick first hand! Sadly I was very hungover that day (exams finished the night before) and didn't fully appreciate it at the time!

Thanks for the kind words!

I just wanted to say that I have been really enjoying your recent articles. You have a great writing style, and the topics you cover are mind-stretchingly fascinating.

Not to mention I had great fun doing the Dirac belt trick and the Feynman plate trick. It's delightful how the great minds of our time invented little party tricks that have deep mathematical connections.

By the way, you may be interested in using Unicode characters U+2329 and U+232A for the bra-ket notation.
