# gst: an approach to information content in the music of J. S. Bach

<< Music has a complex structure that expresses emotion and conveys information. Humans process that information through imperfect cognitive instruments that produce a gestalt, smeared version of reality. What is the information that humans see? And how does their perception relate to (and differ from) reality? To address these questions quantitatively, (AA) analyze J. S. Bach's music through the lens of network science and information theory. >>

They << find that Bach's music is structured for efficient communication; that is, it communicates large amounts of information while maintaining small deviations of the inferred network from reality. >>

They << probe the network structures that enable this rapid and efficient communication of information -- namely, high heterogeneity and strong clustering. (..) More generally, (they) gain insight into features that make networks of information effective for communication. >>

# life: a painted texture glimpsed through 25 words

<< If you want to understand the complicated nature of the United States in 2023, ask Americans to define their country themselves. In the past year, the American Communities Project did just that. It visited four different counties and asked passersby to define 25 words, including America, and the responses showed a range of opinions. >>️

<< The media tends to explain the divides in United States in binary terms — red/blue, left/right, urban/rural. News stories discuss war between two conflicting “cultures” in the country. Sometimes included is a third option for “independents” or “centrists.” But look closer and the picture is far more complicated, marked by fault lines that can be hard to see. >>️

# life: apropos of transitions (in visual perceptions), 'when the reasoning mind melts away, only shapes remain'.

<< Those who drink the hallucinogenic ayahuasca report seeing two-dimensional patterns or throbbing, three-dimensional hexahedral cells. When the reasoning mind melts away, only shapes remain. >>

<< Geometry gives us a world unclad. "Euclid alone has looked on Beauty bare," wrote Edna St. Vincent Millay. That feeling of mystical revelation — of a shimmering, underlying order that we can apprehend if we purify our perception — might explain the mutual affinity between poets and geometers.  (..) Many of the mathematicians cited in Ellenberg’s book (Jordan Ellenberg,  'Shape' ) wrote verse. >>

# s-behav: the intricate performance (dancing and singing) of a jumping spider

AA << present behavioral and neurophysiological evidence that [Jumping spiders (Salticidae)]  perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large (∼3 m) and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level (SPL) >>

<< Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds (80 Hz; 65 dB SPL) by freezing—a common anti-predatory behavior characteristic of an acoustic startle response >>

<< Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones (80 Hz at ∼65 dB SPL)—recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain.  Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. >>

FonT: sarebbe interessante valutare se e quanto tempo prima la struttura neuroacustica del Phidippus audax sia in grado di percepire e discriminare le basse freq dei movimenti  tellurici profondi che successivamente manifesteranno  macro episodi di superficie (earthquake).

# s-brain: only a fraction to keep alive ...

<< We're all living in a 'conceptual prison': our brains perceive a fraction of reality to keep us alive. To help us survive, our perception of truth is limited, says scientist Donald Hoffman >>

<< For millions of years the Australian jewel beetle's reproductive strategy proceeded very effectively. Then, Homo sapiens - and its habit of dumping used beer bottles - entered the picture. Unable to distinguish between these brown glass containers and the shell of a potential mate, the male beetles began attempting to copulate with discarded vessels. "They nearly went extinct" ... >>
