\|	\|	Last year, in a series of posts, I gave you a tour of quantum field theory, telling you some of what weunderstand and some of what we don't. I still haven't told you the role that string theory plays inquantum field theory today, but I am going to give you a brief tour of string...	3.7 parsecs away Travel

\|	\|	Merging quantum mechanics and gravity is a famously hard physics problem. Explaining why merging quantum mechanics and gravity is hard is, in turn, a very hard science communication problem. The more popular descriptions tend to lead to misunderstandings, and I've posted many times over the years to chip away at those misunderstandings. Merging quantum mechanics...	2.1 parsecs away Travel
