\|	\|	Matt Strassler [April 12, 2012] It is common that, when reading about the universe or about particle physics, one will come across a phrase that somehow refers to ``matter and energy'', as though they are opposites, or partners, or two sides of a coin, or the two classes out of which everything is made.

\|	\|	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.
