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. Eliezer Yudkowsky, Rationality: From AI to Zombies physics
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

Imagine the world like a cake Imagine the world like a cake. Imagine that you slice it into the customary slices by vertical cuts. Each slice of that cake should signify for us, a constituency. Each is geographically located as one segment of the larger cake. Each slice is more influenced by its immediate neighbors than by what might be in the cake quite far away. What technology has done in the world increasingly is to put horizontal cuts in that cake. You don't only talk up and down. Now you can talk across barriers. technology
Power makes knowledge sufficient Whether it is civil rights' violations in many countries, whether it is the increasing numbers of unemployed people in our own country, whether it is the homeless we see on our way to work, it isn't as though we don't know. But there is that horrible realization that, while the knowledge of facts may be a necessary condition for action, and we talk about democracy in civic action, it is unfortunately not a sufficient one. While knowledge may be a necessary condition, it may in fact be a less necessary condition that the one that makes that a sufficient condition, and that is access to power. power
To do some more pushups on the internet There may be a lot of things that have to be studied, but there is also what I call "occupational therapy for the opposition" that says, send them off to do some more pushups on the internet. You need to be mindful that it is possible to use information, and the need for information, as a delay for the call for action. informationethicswwwjustice
Adding up to hair-brained I have for myself come to the point where I say that people or groups or governments make the decisions that make sense to them, even if they look totally hair-brained to me. My task then is to figure out the constellation of forces, the pushes and pulls, that in fact do add up to that hair-brained decision-making. Then we can go into the next iteration and say, "What can we do about the balance of the push and the pull that seems to result in totally non-constructive decisions?" decisionsrationality
Who the problems are Recently my attention was drawn to a quote from Peter Drucker who said, "If there isn't dissent, we would not know where the problems are." I said to my husband, "Look, if there isn't dissent, we wouldn't know who the problems are." I think one has to keep that in mind. Peter F. Drucker argument

Cyberspace as a global dump If we think that cyberspace is a public space, then let's think of the oceans. They used to be as much of a world resource as anybody could think of but didn't belong to anybody. So everybody put their garbage into them. The potential of cyberspace as a global dump is quite substantial. naturetrash
