"First they came for the Communists,
and I didn’t speak up,
because I wasn’t a Communist.
Then they came for the Jews,
and I didn’t speak up,
because I wasn’t a Jew.
Then they came for the Catholics,
and I didn’t speak up,
because I was a Protestant.
Then they came for me,
and by that time there was no one
left to speak up for me."

Proposed Cloaking Device for Water Waves Could Protect Ships at Sea
Submitted by Melinda L. Secor on Sun, 2012-03-04 01:00
"The weird science of invisibility has entered uncharted waters. By altering the sea floor in just the right way, it should be possible to hide an object floating on the sea from passing waves, a fluid mechanician predicts. The technique might help to protect ships and floating structures from rough seas. And because the scheme works entirely differently from the 'cloaks' developed to hide objects from light and other electromagnetic waves, it breaks new ground for research."
