On a Wing and a Prayer.

This unique Tennessee duckling, Buttercup, was born with one foot in the grave. His backward foot meant he had trouble walking, swimming and he was constantly in pain. He was adopted by Feathered Angels in Arlington Tennesse who noted that he risked falling fowl of serious infection due to the constant cuts on his troubled foot.

Chladni patterns are really awesome. (GIF series.)

This phenomenon occurs when sound waves of particular frequencies are played through a metal plate causing it to vibrate. If you place salt or a similar grains on the plate, it accumulates in the places of least displacement (nodes). Nodes and anti-nodes occur due to constructive and destructive interference – when coinciding waves either reinforce each other or cancel each other out.  The amazing thing is, as you adjust the frequency of the sound wave, the interference patterns change drastically – with some pretty cool results. These patterns take their name from Ernst Florens Friedrich Chladni who was was a German physicist and musician. I’m sure you’ll agree that this is nothing short of some  handsome science.
