Hi Stephon,
Great read. So what is going to happen with the paper? The suspense is killing me.

My only criticism to Peskin is that his book come too late to save the physicist generation of the early nineties. Old books too old, new books still a chaos of patchwork.

Neil, the paper is coming out on Monday, but I'll blog about it later today.

So what were the 5 best papers!?

Stephon,

Very funny, does Michael read your blog regularly?

(and belated congratulations, I am discovering so many of these blogs these days, hard to keep up).

Stephon,

Your paper looks really interesting. I am sure you were already asked this question: Weinberg has a no-go thm. regarding what he calls "adjustment mechanisms" (for example his 1989 review, section 6), how do you evade those?

thanks,

Moshe

Moshe,
This is a good question. I haven't put much thought into Weinberg's no-go theorem. I am aware of it naively. Let me think about it. Please let me know what you think about the idea as I really value your insight.

Hi Stephon,

Thanks, but I have to disappoint you, my insight into LQG is basically zero, after moderate amount of effort. I always run into the same brick wall, understanding how formal statements in the theory are connected with conventional classical and semi-classical GR.

An example is my question above- Weinberg's thm. is a statement in classical GR coupled to axion-like fields with some potential, presumably one of the assumptions does not hold in LQG.

Anyhow, nice paper, I'll try to understand better.

best,

Moshe
