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
In Defense of a Fussy Website An Article by Sarah Drasner css-tricks.com Fussy breakfastsEggs, Easter and poached
Fussy breakfasts The other day I was doom-scrolling twitter, and I saw a delightful article titled “The Case for Fussy Breakfasts.” I love food and especially breakfast, and since the pandemic hit I’ve been using my breaks in between meetings (or sometimes on meetings, shh) to make a full bacon, poached egg, vegetable plate, so I really got into the article. This small joy of creating a bit of space for myself for the most important meal of the day has been meaningful to me — while everything else feels out of control, indulging in some ceremony has done a tiny part to offset the intensity of our collective situation. It caused me to think of this “fussiness” as applied to other inconsequential joys. A walk. A bath. What about programming? While we’re all laser-focused on shipping the newest feature with the hottest software and the best Lighthouse scores, I’ve been missing a bit of the joy on the web. Apps are currently conveying little care for UX, guidance, richness, and — well, for humans trying to communicate through a computer, we’re certainly bending a lot to… the computer.
Eggs, Easter and poached When a site is done with care and excitement you can tell. You feel it as you visit, the hum of intention. The craft, the cohesiveness, the attention to detail is obvious. And in turn, you meet them halfway. These are the sites with the low bounce rates, the best engagement metrics, the ones where they get questions like “can I contribute?” No gimmicks needed. What if you don’t have the time? Of course, we all have to get things over the line. Perhaps a challenge: what small thing can you incorporate that someone might notice? Can you start with a single detail? I didn’t start with a poached egg in my breakfast, one day I made a goofy scrambled one. It went on from there. Can you challenge yourself to learn one small new technique? Can you outsource one graphic? Can you introduce a tiny easter egg? Say something just a little differently from the typical corporate lingo? wwwdetailsux
