Liking the article just fine, but cannot help noticing oddities like these:
quote:
A spin-$latex \frac{1}{2}$ particle must complete two full rotations to come back to the same state, while a spin-2 particle looks identical after just half a turn. Elementary particles can only carry 0, $latex \frac{1}{2}$, 1, $latex \frac{3}{2}$ or 2 units of spin.
LaTeX was (probably still is) a very popular type-setting software among academics in the hard sciences and engineering for writing papers, and it's very good at rendering mathematical expressions beautifully. It's just unexpected to see LaTeX used in a popular press article like this (and apparently the draft-to-web publishing system in this case does not know how to properly deal with LaTeX expressions).
