Just a reminder:the natural diet of these birds is BONES. Not just bone marrow; actual bone shards. They pick up huge freaking bones from carcasses and drop them onto rocks until they get spiky pieces and then they swallow them. Their stomach acid dissolves bone. Also fact: when sufficiently threatened, they’ve been observed to deliberately puke on the threat.

Iris paintings by Marc Quinn

One of my favorite part of dissection labs was eyes. The iris is so interesting and beautiful. It’s kinda hard to wrap your brain around it being layers of muscle fibers and not just a flat piece of color. The variations from person-to-person and fiber-to-fiber are amazing.

Black Holes

Cosmic sink-holes or Black Holes is a region of spacetime from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called “black” because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics. Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.
