On: A Chemist Shines Light on a Surprising Prime Number Pattern

[knicholes]

"Shining light" on something is kind of a metaphor for figuratively illuminating something, or showing something more clearly (pretend someone shines light on something in the dark). More precisely, I believe this is saying that a chemist is providing more information about a prime number PATTERN.

It's a bit of a pun too, since crystallography is, in essence, shining a light on something and studying what comes back.
