Paige Bradley created one of the most striking sculptures I’ve seen in recent times. Her masterpiece, entitled Expansion, is a beautiful woman seeking inner piece but fractured and bleeding with light. “From the moment we are born, the world tends to have a container already built for us to fit inside: a social security number, a gender, a race, a profession,” says Bradley. “I ponder if we are more defined by the container we are in than what we are inside. Would we recognize ourselves if we could expand beyond our bodies?”
When a drop falls from a moderate height into a shallow pool, its impact creates a complicated pattern. The photo above is a composite image showing a top-down view 100 ms after such an impact. On the left side, the flow is visualized using dye whereas the right shows a schlieren photograph, in which contrast indicates variations in density. Both methods show the same general structure - an inner vortex ring generated at the edge of the impact crater and formed mostly of drop fluid and an outer vortex ring, consisting primarily of pool fluid, formed by the spreading wave. Both regions show signs of instability and breakdown. (Photo credit: A. Wilkens et al.)
Loligo gigas [now Dosidas gigas] - Humboldt Squid/Jumbo Squid
The Humboldt squid is among the largest of the squid, despite their lifespan of just under one year. Other giant squids have a lifespan estimated to be around five years at a minimum, and don’t reach their maximum size until near the end of their life. One of the major sources of food for Humboldt squid is other Humboldt squids, which is believed to contribute significantly to their fast growth.
All of the suckers of the Humboldt are ringed with sharp, flesh-tearing teeth, and when squid are feeding, they’ve been known to be very aggressive towards scuba divers. Outside of feeding time (generally dusk to dawn), the squid are generally non-aggressive creatures.
Like many squid, the Humboldt has chromatophores in its skin, allowing for rapid color changes. When they feed or are in distress (such as when they’re caught by fishers), they flash bright red. This led to one of their first colloquial names - El diablo rojo - the Red Devil.
