Nope, no voting ring - I'm pretty surprised it hit the front page to be honest. In fact, I was debating whether to post it at all as it is obviously not startup/tech related. Then again, I'd seen a few other physics related posts pop up so I thought it might have some appeal.
Given that you're a physics PhD, I'd love to hear your thoughts on how the post could be improved. I'm keen to expand it and "fill in the gaps" that others have suggested.
I don't see the problem is that there are gaps, it's that it's just too much stuff. The reason it seems spammy to me is that it's a big dump of stuff that isn't well categorized.
To really get on top of all that stuff is a huge project, and the best way you're going to do it is by solving problem sets for a few years.
From my current viewpoint, I'd pick something really specific (say, modern models of quantum black holes) and try to develop the straightest line to it. Of course, I blew 9 years getting an undergrad and grad degree so I've got that base.
