Hahaha, I hope it will be finished before I die.
Well, some of the best books, such as Sakurai's QM, were finished after the author's death.
...and some of the best textbook weren't even written by their authors (the famous 10-volume theoretical-physics series by Landau are an example, being written by Lifshitz et al using of course Landau's ideas).
Or, as it is sometimes so eloquently expressed: ”Not a word by Landau, not a thought by Lifshitz.”
I think the same is true for Feynman Lectures on Gravity.
The poor man passed away before his 50th birthday. I hope I will not have similar destiny . And, I am not sure if he would approve "all of" the current version of "his book" on QM.
Well, the additions by Napolitano, I'm pretty sure he wouldn't. I can't imaging that Sakurai would approve a chapter about old-fashioned 1st-quantization relativistic QM, which only adds to the confusion! I'm glad to have the "revised edition" edited by Tuan.
Is there anyone who doesn't want to live forever?
So many books, papers to read and write. :-)
Edit: and of course correcting others mistakes... that's heaven!
