EAST LANSING, Mich. (AP) — Who says science doesn't turn people on? Kate McAlpine is a rising star on YouTube for her rap performance — about high-energy particle physics.

Her performance has drawn a half-million views so far on YouTube.

The 23-year-old Michigan State University graduate and science writer raps about the Large Hadron Collider, the groundbreaking particle accelerator that has been built in a 17-mile circular tunnel at the CERN laboratory near Geneva.

McAlpine raps that when the collider goes into operation on Sept. 10, "the things that it discovers will rock you in the head."

The $3.8 billion machine will collide two beams of protons moving near the speed of light so scientists can see what particles appear in the resulting debris.
