A holograph of itself All [physical properties of matter] derive from the different patterns of the interaction of electrons and photons within the fields of the positively charged atomic nuclei, stabilized in a particular morphology by the interaction of the levels themselves. Matter is a holograph of itself in its own internal radiation. Matter versus Materials: A Historical View physics
Reality just seems to go on crunching I once met a fellow who thought that if you used General Relativity to compute a low-velocity problem, like an artillery shell, General Relativity would give you the wrong answer—not just a slow answer, but an experimentally wrong answer—because at low velocities, artillery shells are governed by Newtonian mechanics, not General Relativity. This is exactly how physics does not work. Reality just seems to go on crunching through General Relativity, even when it only makes a difference at the fourteenth decimal place, which a human would regard as a huge waste of computing power. Physics does it with brute force. No one has ever caught physics simplifying its calculations—or if someone did catch it, the Matrix Lords erased the memory afterward.

Corpuscles of nothing and atoms of something The structure of matter devolved ultimately into the intimate coexistence of something like corpuscles of nothing and atoms of something, segregating through the accidents of history to yield regions differing in density intimately interwoven on different scales. The experience of the world as well as human perception and analysis of any part of it is a matter of the angular scale of resolution and of the time necessary for making comparison between the different parts. Without such variations and without time to compare remembrances of them, nothing can be experiences.

The Iridium System Several Low-Earth-Orbit (LEO) networks were proposed, but only one got off the ground: the Iridium system. The original Iridium proposal called for a "constellation" of 77 satellites, which gave the plan its name: the element iridium has atomic number 77, meaning that an iridium atom has 77 orbiting electrons. Before the satellites were launched, the constellation was scaled back to 66 active satellites, but no one wanted to change the name to Dysprosium.

Fermi Estimates and Dyson Designs An Article by Venkatesh Rao www.ribbonfarm.com A Fermi estimate is a quick-and-dirty solution to an arbitrary scientific or engineering analysis problem. Fermi estimation uses widely known numbers, readily observable phenomenology, basic physics equations, and a bunch of approximation techniques to arrive at rough answers that tend to be correct within an order of magnitude or so. The term is named for Enrico Fermi, who was famously good at this sort of thing. …It struck me that there is counterpart to this kind of thinking on the synthesis side, where you use similar techniques to arrive at a very rough design for a complex engineered artifact. I call such a design approach Dyson design, after the physicist Freeman Dyson, who was one of the best practitioners of it (not to be confused with inventor James Dyson, whose designs, ironically, are not Dyson designs). designphysics
The Interpretation of Microstructures of Metallic Artifacts An Essay from A Search for Structure by Cyril Stanley Smith The meaning of objectsSomething akin to styleFrom the head of JoveThe objects themselves speak loudlyThe way it has been made+1 More
Something akin to style My own attitude toward the microstructure of metals is not unlike that of an art historian regarding a painting or sculpture. There is something akin to style even in a photomicrograph. There are aspects of structure that are not immediately apparent to the untrained eye, and quite minor features may be clues to a deep meaning. style
From the head of Jove A complex structure is a result of, and to a large extent a record of, its past. Though a proton and an electron may, as a pair, be able to spring full-panoplied from the head of Jove, more complex things cannot, or at least do not. Everything complicated must have had a history, and its internal structural features arise from its history and provide a specific record of it. One might call these structural details of memory “funeous,” after the unfortunate character in Borge’s story “Funes the Memorious” who remembered everything.

The objects themselves speak loudly The written record is very little help in determining the techniques used by ancient metalworkers, though the objects themselves speak loudly to an educated ear.
The way it has been made The internal structure of a work of art in metal can often throw as much, or more, light on its origin as can be derived from stylistic analysis. Moreover, the techniques employed can provide clues to the habits of mind of the people who originated them. …Perhaps the most important reason for structural studies of museum objects is that the intimate knowledge so derived as to the way in which an object has been made adds so greatly to the aesthetic enjoyment of it. Very often some detail and sometimes the whole of an effective design arises directly in the exploitation of the merits and the overcoming of the difficulties of a specific technique, in the reaction between the artist’s fingers and his material. historytechniquemakingobjects
Aesthetically motivated curiosity It seems that the first and most imaginative use of practically every material was, before quite modern times, in making something decorative. People are experimentally minded when looking for decorative effects, but they can’t experiment with the established techniques on which their livelihood depends. / It is of basic significance for human history that, from the cave paintings on, almost all inorganic materials and treatments of them to modify their structure appear first in decorative objects rather than in tools or weapons necessary for survival. Aesthetically motivated curiosity, or perhaps just play, seems to have been the most important stimulus to discovery. materialexperiments
