At first, I thought Physics News Graphics was a joke because of the text that accompanies this cool image:
New experiments and simulations show that large-scale fluid circulations drain energy from smaller-scale vortices to sustain themselves, akin to a hostile takeover of smaller corporations. The figure shows a visualized flow from a laboratory experiment of a thin salt-water layer driven by magnetic forces. One can see vortex structures on a range of scales.
But if you look at the other images, you'll see that the other text is serious, such as this:
Sketch of an acoustic lens based on a two-dimensional sonic crystal and a map of the resulting sound level (in dB). The sketch is drawn to scale. The lens-like sample measure 1.2 m of width. In this experiment, the researchers use a sonic crystal consisting of a triangular lattice of 4-cm-diameter cylinders, the pitch being 6.35 cm. The sound pressure map
has been taken at a frequency of 1700 Hz, which is well below the first acoustic gap that starts at 2300 Hz.
So I'm assuming the site is serious. BTW--I have no idea what that means, or much else on the site. Mahndisa probably understands, since I found out about it from her. But visit the site--you'll be looking at the images all day, like this one:
