HEISENBERG IN SHELLS. “Fig. 7. Possible realizations of ancestors. For each neural network parameter at each node, five values were drawn from their estimated distribution by using the predicted uncertainty around the maximum-likelihood estimate.” https://lnkd.in/dwfZQzE View in LinkedIn

SO ENDS this second section on cone shell patterns. When a small blob of tissue resembling gristle which lives within a shell can generate patterns and colors of such mathematical complexity, it makes you appreciate the mental capabilities of the merest creature. That this animal can visualize and execute such a pattern on an unfolding 3D curve is further evidence. Humans have long assumed the worst of humble creatures, or simply not counted them at all.

PHYLOGENY CORRELATES. “These observations are confirmed by standard parsimony statistics and their comparison with randomized-tip null models; presence/absence of stripes, despite these being visually striking patterns used in identification, appear to lack significant phylogenetic signal in that they do not show significantly more congruence with the phylogeny than is expected under the null model in which character states have been randomly shuffled among the phylogeny tips.” https://lnkd.in/dwfZQzE View in LinkedIn

NEURAL CONTROL. “Accumulating evidence now indicates clearly that shell growth and patterning are under neural control and that shell growth and pigmentation is a neurosecretory phenomenon. Most of this evidence has been gained by detailed studies of the mantle, a tongue-like protrusion of the mollusk that wraps around the edge of the shell and deposits new shell material and pigment at the shell’s growing edge.” https://lnkd.in/d7D7yyC View in LinkedIn

ENERGY INPUT. “As all magnetospheric activity is powered by energy input from the solar wind, detailed understanding of the energy transfer processes and mechanisms is a key challenge for space weather applications.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

MAGNETIC SCULPTING OF THE COSMOS. “The tail radius and flaring angle (deviation from a cylindrical shape) are to some extent controlled by the interplanetary magnetic field direction, which controls the intensity of reconnection at the nose of the magnetosphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

BEYOND COMPUTATION. “There has recently been proposed a limit on the computational power of the universe, i.e. the ability of Laplace's demon to process an infinite amount of information. The limit is based on the maximum entropy of the universe, the speed of light, and the minimum amount of time taken to move information across the Planck length, and the figure was shown to be about 10(120) bits. Accordingly, anything that requires more than this amount of data cannot be computed in the amount of time that has elapsed so far in the universe.” https://en.m.wikipedia.org/wiki/Laplace%27s_demon View in LinkedIn

MAGNETOSPHERE SIZE. “The size and shape of the magnetosphere is controlled by the interaction of the interplanetary magnetic field and solar wind flow with the internal geomagnetic field and the magnetospheric plasma environment. The size is largely controlled by the solar wind dynamic pressure, which is balanced by the magnetic pressure inside the magnetosphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
