The most common example of this phenomenon can be seen in the rotation of the Earth itself. Known primarily as precession of the equinoxes, the axial spinning of the Earth essentially traces out the shape of a cone as it orbits the Sun. This occurs within the Earth's orbit every 25,800 years and results in the slow change of the location of the stars in the night's sky. While the stars themselves do not actually change position, their location as compared to coordinates on the planet's surface alter. Observers of this shift on the Earth's crust can identify only a one degree change every 72 ye…
What is Precession?
deformation of the ambient space is fully parametrized by an initial set of control points and an initial set of momenta

we need to be able to parametrize a large family of transformations of the 2D or 3D space as well as to be able to compute distances between the objects.

Indeed, the symbolic meaning some of his viewers attributed to his films often baffled him: “I make pictures for entertainment, and then the professors tell me what they mean.”

Whatever was meant by these stencils, there can be no stronger message in viewing them: We are human. We are here. I raise my own hand to meet one, fingers hovering an inch above the ancient outline. It fits perfectly.

In a low chamber inside, pigs amble across the ceiling. Two appear to be mating—unique for cave art, Ramli points out. Another, with a swollen belly, might be pregnant. He speculates that this is a story of regeneration, the stuff of myth.

Clottes has championed the theory that in Europe, where art was hidden deep inside dark chambers, the main function of cave paintings was to communicate with the spirit world. Smith is likewise convinced that in Africa, spiritual beliefs drove the very first art.

For ice age European cave painters, horses, rhinos, mammoths and lions were less important as dinner than as inspiration. Ancient Sulawesians, it seems, were likewise moved to depict larger, more daunting and impressive animals than the ones they frequently ate.

In piloting the curriculum, Jablonski and fellow instructors treated it as a research study—observing and taking notes on students’ reaction to the curriculum, initiating student-based reflection and interviews as a way to understand the true effectiveness of the program

Yet there are thought-provoking similarities between the earliest Sulawesian and European figurative art—the animal paintings are detailed and naturalistic, with skillfully drawn lines to give the impression of a babirusa’s fur or, in Europe, the mane of a bucking horse.

The youngest stencil was dated to no more than 27,200 years ago, showing that this artistic tradition lasted largely unchanged on Sulawesi for at least 13 millennia.

So it has long been assumed that sophisticated abstract thinking, perhaps unlocked by a lucky genetic mutation, emerged in Europe shortly after modern humans arrived there about 40,000 years ago.

Leang Jarie means “Cave of Fingers,” named for the dozens of stencils decorating its walls. Like Leang Timpuseng, it is covered by small growths of white minerals formed by the evaporation of seeping or dripping water, which are nicknamed “cave popcorn.” “I walked in and bang, I saw these things. The whole ceiling was covered with popcorn, and I could see bits of hand stencils in between,” recalls Brumm. As soon as he got home, he told Aubert to come to Sulawesi.

Archaeologists in South Africa have found that the pigment ocher was used in caves 164,000 years ago. They have also unearthed deliberately pierced shells with marks suggesting they were strung like jewelry, as well as chunks of ocher, one engraved with a zigzag design—hinting that the capacity for art was present long before humans left Africa.

The technique, known as uranium series dating, was used to determine that zircon crystals from Western Australia were more than four billion years old, proving Earth’s minimum age.

Of the 43 muscles that comprise the human face, only a few are actually important to speaking. And yet replicating the movements of the mouth by mechanical means always seems to end up only partly convincing. Servos and linkages can only approximate the complex motions the lips, cheeks, jaw, and tongue are capable of.
