The physics of curly hair

February 14, 2014 8:23 am | by Denise Brehm, Civil and Environmental Engineering | News | Comments

The heroes and villains in animated films tend to be on opposite ends of the moral spectrum. But they’re often similar in their hair, which is usually extremely rigid or straight and swings to and fro. It’s rare to see an animated character with bouncy, curly hair, since computer animators don’t have a simple mathematical means for describing it. That is, until now.

Source of “Moon Curse” revealed by eclipse

February 12, 2014 8:51 am | by Susan Brown, UC Davis | News | Comments

Strange events have long been linked to nights of a full moon, though careful scrutiny dispels any association. So, when signals bounced off the lunar surface returned surprisingly faint echoes on full moon nights, scientists sought an explanation in reason rather than superstition. Still, the most compelling evidence arrived during another event that once evoked irrational fears, on a night when Earth's shadow eclipsed the full moon.
