Quantum Fun
When we get things down to the quantum scale many interesting things happen that are counterintuitive. Like this:
Blocked holes can enhance rather than stop light going through
In an example of the extraordinary twists of physics that can occur at very small scales, electrical engineer Stephen Chou and colleagues made an array of tiny holes in a thin metal film, then blocked each hole with an opaque metal cap. When they shined light into the holes, they found that as much as 70 percent more light came through when the holes were blocked than when they were open.
