“I see a lot of things as being like parasites. Parasites are the most successful life-form on Earth. It could be as many as three parasites for every free living species, its hard to say. If you’re not a species living inside another thing, then you’re a species with something living inside of you.” Carl Zimmer, author of Parasite Rex: Inside the Bizarre World of Nature’s Most Dangerous Creatures, on cute dogs
In the dark ocean, two hundred fifty foot waves roll very slowly down long underwater slopes: “The deep waves have the distinguishing curl of Kelvin-Helmholtz billows, a type of wave present throughout nature. Scientists have long tracked these distinctive waves, finding them on the windblown sea, on sand dunes, among clouds and even in the churning gases of Saturn and Jupiter. They originate when two fluids, or gases, (or sea and air), move past one another at different speeds. At the boundary, the interaction produces a sequence of crests that rise gently and then curl into chaotic turbulence…” David Choad, on deep sea waves
