Gravitational wave detectors: the universe ripples, they listen.
These detectors (
LIGO,
GE600, TAMA300, AIGO) are listening for the gravitation waves: black holes spinning and colliding, or neutron stars inspiralling to their final fates in a black hole.

Cymatics is the study of visible sound and vibration, typically on the surface of a plate, diaphragm, or membrane. Directly visualizing vibrations involves using sound to excite media often in the form of particles, pastes, and liquids. The apparatus employed can be simple, such as a
Chladni Plate or advanced such as the
CymaScope, a laboratory instrument that makes visible the inherent geometries within sound and music.
Hans Jenny (1904-1972) is considered the father of cymatics.

September 30th, 2002, scientists intercepted a 10 minute radio burst from the galactic center, 26,000 Light Years away. 77 minutes passed, and it repeated. And again. The signal repeated 5 times that evening.
Some think those signals are
weird mysterious.
Others think they are
interesting mysterious.

Kiteboarding is an argument for the existence of God. And even if, like me, you don’t buy that particular argument, it’s still insanely cool. Armed with a kite, a harness and a board, you can
show up your local skate rats (soundtrack includes language that is
Not, strictly speaking,
Safe For Work), fly over
snow, ride
waves and even indulge yourself over
plain-vanilla dry land. Be careful, though. If angered, the wind could easily
take you into orbit.

Surf's Up! While many of us in North America are battling freezing rain, sleet, snow, and other sub-zero madness, the folks on the north shore of Oahu are enjoying their own December
weather phenomenon.

Heavy Seas is an all too brief gallery of terrifying photos of huge waves crashing down around large boats & drilling rigs. I wish it were a little longer, but I did think the photos were impressive, as one who has never been at sea in very rough weather.
