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
Skeleton, Organs, Circulation, Sinew, Skin An Article by Dorian Taylor I’m concerned with how I witness the work of user experience practitioners getting treated: like it’s just a set of motions toward a product’s all-important implementation, and one that we try to compress, due to its ostensible superfluity. Once the implementation is finished, the UX work appears to usually get discarded. Tracing the answer backThe UX coral reef ux
Tracing the answer back I submit that the materials that form the precursors to a product’s implementation have considerable value on their own. My vision is that I will be able to ask a question as mundane as one about the wording of a single button, and trace the answer all the way back to the overarching business strategy to see that it makes sense. decisions
The UX coral reef It isn’t a site, or a service, or even an identifiable product at all, but rather a system for creating a skin around and connective tissue between things like: Demographic studies Contextual inquiries Stakeholder and user interviews Surveys The business ecosystem Personas Scenarios Sketches, storyboards, wireframes Mockups, models and prototypes Email and IM conversations Meeting notes Content inventories and audits Concept schemes, taxonomies, thesauri A UI style guide A branding and visual identity guide A voice and tone guide A code style guide ...etc The individual elements of such a corpus represent the work of half a dozen specialist sub-disciplines, and are useful for realizing a product’s implementation. But if you hook them all up together, they merge to become a strategic artifact that transcends products and operates as a critical control surface for the business. This is because what such an artifact represents is a coral reef of deeply-considered and hard-fought decisions, and a story of the process that yielded them. connection
