Money is a human construct which has no real value in terms of the planet. When we have consumed all the planet’s resources money will not save us.
This is what I’m always saying.

When reading text or listening to someone speak, we construct rich mental models that allow us to draw conclusions about other people, objects, actions, events, mental states and contexts. This ability to understand written or spoken language, called “discourse comprehension,” is a hallmark of the human mind and central to everyday social life. In a new study, researchers uncovered the brain mechanisms that underlie discourse comprehension.
The study appears in Brain: A Journal of Neurology.
With his team, study leader Aron Barbey, a professor of neuroscience, of psychology, and of speech and hearing science at the University of Illinois, previously had mapped general intelligence, emotional intelligence and a host of other high-level cognitive functions. Barbey is the director of the Decision Neuroscience Laboratory at the Beckman Institute for Advanced Science and Technology at Illinois.
To investigate the brain regions that underlie discourse comprehension, the researchers studied a group of 145 American male Vietnam War veterans who sustained penetrating head injuries during combat. Barbey said these shrapnel-induced injuries typically produced focal brain damage, unlike injuries caused by stroke or other neurological disorders that affect multiple regions. These focal injuries allowed the researchers to pinpoint the structures that are critically important to discourse comprehension.
“Neuropsychological patients with focal brain lesions provide a valuable opportunity to study how different brain structures contribute to discourse comprehension,” Barbey said.
A technique called voxel-based lesion-symptom mapping allowed the team to pool data from the veterans’ CT scans to create a collective, three-dimensional map of the cerebral cortex. They divided this composite brain into units called voxels (the three-dimensional counterparts of two-dimensional pixels). This allowed them to compare the discourse comprehension abilities of patients with damage to a particular voxel or cluster of voxels with those of patients without injuries to those brain regions.
The researchers identified a network of brain areas in the frontal and parietal cortex that are essential to discourse comprehension.
“Rather than engaging brain regions that are classically involved in language processing, our results indicate that discourse comprehension depends on an executive control network that helps integrate incoming language with prior knowledge and experience,” Barbey said. Executive control, also known as executive function, refers to the ability to plan, organize and regulate one’s behavior.
“The findings help us understand the neural foundations of discourse comprehension, and suggest that core elements of discourse processing emerge from a network of brain regions that support language processing and executive functions. The findings offer new insights into basic questions about the nature of discourse comprehension,” Barbey said, “and could offer new targets for clinical interventions to help patients with cognitive-communication disorders.
“Discourse comprehension is a hallmark of human social behavior,” Barbey said. “By studying the mechanisms that underlie these abilities, we’re able to advance our understanding of the remarkable cognitive and neural architecture from which language comprehension emerges.”

The ancient Egyptians discovered that regular polygons can be increased while still maintaining the ratio of their sides by the addition of a strictly constructed area (which was later named the “gnomon” by the Greeks); the Egyptians assigned the concept of the ratio-retaining expansion of a rectangular area to the god Osiris, who was, therefore, often shown in ancient Egyptian frescoes seated on a square throne (square= kingship again) in which the original square and its L-shaped gnomon are clearly delineated, but the geometrical construction used to create the gnomon is not shown. It is, in fact, the absense of the attendent arcs and extension lines used in the creation of geometric forms that has led art historians and iconographers such a merry chase through history. It often takes the eye of a geomterician to spot the tell-tale signs of construction.
One of the best-known pieces of detective work in this regard was the discovery by Jay Hambidge, an art historian at Yale University during the 1920s, that the spirals on the Ionic column capitals of ancient Greek temples were laid out by the so-called “whirling rectangle” method for creation of a logarithmic spiral. He realized this by examining numerous Ionic capitals in art museums until he located some in which the holes made by the placement of compass points had not been obliterated over time. (One of these capitals was an unfinished, broken piece, dug up from a rubbish heap near a temple — it had apparently been damaged during manufacture and was discarded; its burial preserved it from the elements, and the marks of the geometeric layout were remarkably clear upon it.) No “sacred meaning” for the log spiral form of the Ionic column capital has been determined from Greek writings, but the use of other log spirals in Greek temple architecture (for instance in floor-block proportions and their placement in relation to overall floor area) indicates that Greek architects, unlike the Romans who came after them, deliberately constructed their temples according to “whirling rectangle” geometeric ratios.

Oh my word. These are stunning.
I don’t know—just the fact of *real, tangible, everyday objects* being turned into something so elegant and mathematically precise—it sings to me.
