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 eyes of a traveler We’ve all heard that travel broadens the mind. But beneath this cliché lies a deep truth. Things stand out because they’re different, so we notice every detail, from street signs to mailboxes to two you pay at a restaurant. We learn a lot when we travel, not because we are any smarter on the road but because we pay such close attention. On a trip, we become our own version of Sherlock Holmes, intensely observing the environment around us. We are continuously trying to figure out a world that is foreign and new. Too often, we go through our day-to-day life on cruise control, oblivious to huge swaths of our surroundings. To notice friction points – and therefore opportunities to do things better – it helps to see the world with fresh eyes. When you meet creative people with lots of ideas constantly bubbling to the surface, you often come away feeling that they are operating on a different frequency. And they are, most of the time. They have all their receptors on — and frequently turned up to eleven. But the fact is, we are all capable of this mode. Try to engage a beginner’s mind. For kids, everything is novel, so they ask lots of questions, and look at the world wide-eyed, soaking it all in. Everywhere they turn, they tend to think, Isn’t that interesting? rather than, I already know that. By adopting the eyes of a traveler and a beginner’s mindset, you will notice a lot of details that you might normally have overlook. You put aside assumptions and are fully immersed in the world around you. In this receptive mode, you’re ready to start actively searching out inspiration.
