@joannekcheung: fractal boats are needed for navigating the fractal coastline
@bensauer: Given that their model is based on Xerox PARC, that would indeed echo history. They can't *not* have thought about this outcome.
@bensauer Briefly: PARC (& most labs) developed technology *intended* to be productized and consumed. Dynamicland's strategy is to avoid productization entirely, by creating a medium that people learn to make for themselves, stewarded by new public institutions. See dynamicland.org/dynamicland-501c3-narrative.pdf
@TurtlingB: @worrydream had his ‘kill math’ project a few years back. i assume it was a stepping stone to dynamicland
@TurtlingB The other way around, actually.
optimize for malfunction
Percy Williams Bridgman (April 21, 1882 - August 20, 1961) was an American physicist who received the 1946 Nobel Prize in Physics for his work on the physics of high pressures.
Bridgman entered Harvard University in 1900, and studied physics through to his Ph.D. From 1910 until his retirement, he taught at Harvard, becoming a full professor in 1919. In 1905, he began investigating the properties of matter under high pressure. A machinery malfunction led him to modify his pressure apparatus; the result was a new device enabling him to create pressures eventually exceeding 100,000 kg/cm? (10 GPa; 100,000 atmospheres). This was a huge improvement over previous machinery, which could achieve pressures of only 3,000 kgf/cm? (0.3 GPa) 1] This new apparatus led to an abundance of new findings, including a study of the compressibility, electric and thermal conductivity, tensile strength and viscosity of more than 100 different compounds.
@qualmist: That looks great. It reminds me of when I did "3D in Apparatus"...
@qualmist @mandy3284 That reminds me of when I did "3D in Realtalk"...
@qualmist 2.5D ought to be enough for anybody
how to tell whether you're using a computer or an arcade game
the Japanese software community had influenced the microcomputer industry in the United States for several years, particularly in the days of the video game machines that preceded microcomputers. Although arcade games were not computers because they could not be programmed by the people who used them, they contained microprocessor chips, and that meant that the most important element in the video game systems was the software that instructed each chip to play the game designed for it.

"the nursery rhymes of our subject" (Ziman / Goodsell)
It used to be thought that all the states in metals could be described in this way, by bringing in enough different atomic orbitals. The picture of states overlapping and broadening to make nice valence and conduction bands illustrates one of the nursery rhymes of our subject (fig. 4). Unfortunately, this is quite misleading. What happens is that as the atomic potentials overlap. and the barriers fall between atomie cells, most of these atomic bound-state orbitals disappear.
The first thing we learn in molecular biology class is the central dogma, presented with almost religious fervor: DNA begets RNA begets protein. Then, we're all properly mortified when we learn of the heretical ways that viruses corrupt this natural flow of information, building RNA from RNA or, even worse, DNA from RNA. The reverence we feel is well founded; when we look at the
"able to reproduce everything" (Plato / Mead)
Plato, Republic, Book X, p 598b
'What I mean is this. If you look at a bed, or anything else, sideways or endways or from some other angle, does it make any difference to the bed? Isn't it merely that it looks different, without being different? And similarly with other things.'
'Yes, it's the same bed, but it looks different.'
'Then consider - when the painter makes his representation, does he do so by reference to the object as it actually is or to its superficial appearance?' Is his representation one of an apparition? or of the truth?'
'Of an apparition.'
'The art of representation is therefore a long way removed from truth, and it is able to reproduce everything because it has little grasp of anything, and that little is of a mere phenomenal appearance. For example, a painter can paint a portrait of a shoemaker or a carpenter or any other craftsman without understanding any of their crafts; yet, if he is skilful enough, his portrait of a carpenter may, at a distance, deceive children or simple people into thinking it is a real carpenter.'
'Yes, it may.'
'In all such cases,' I went on, 'we should bear the following considerations in mind. When someone tells us that he has met someone who is a master of every craft and has a more exact understanding about all subjects than any individual expert, we must answer that he is a simple-minded fellow who seems to have been taken in by the work of a charlatan, whose apparent omniscience is due entirely to his own inability to distinguish knowledge, ignorance, and representation.'

Mead, The Universe and Us, 18:44
We had started out [via de Broglie and Schrödinger] having a physical picture of the electron as a wave propagating around the proton... it all made perfect sense intuitively. But then you got some fancy mathematics that made it unnecessary to have the physical picture. And then Bohr argued that “We're above all that now. We don't need physical pictures. We don't need to use intuition.”...
Now don't get me wrong, there's nothing wrong with mathematics. [It's the language we use to express the precise relations of physical law.] But what got propagated was the notion that mathematics had become the guide to physical theory. ...
One of the things that I've developed through my life is an enormous respect for the power of mathematics. I know a lot of mathematicians, they're very bright, and one of the things I've come to realize is that you can, if you're good enough, develop a mathematics for any physical theory — whether it's what nature does or not. So in fact if you say that mathematics is going to guide what physics does, all you're saying is that you've let go of the fact that what the real world does should be guiding what your physics is. Because the mathematics can express anything.
"several centuries, and sometimes even a millennium or more" (worrydream.com/refs/Goody…)
appears to be true of India and Palestine, Gandz notes, for example, that Hebrew culture continued to be transmitted orally long after the Old Testament had begun to be written down. As he puts it, the introduction of writing:
did not at once change the habits of the people and displace the old method of oral tradition. We must always distinguish between the first introduction of writing and its general diffusion. It often takes several centuries, and sometimes even a millennium or more, until this invention becomes the common property of the people at large.
