Then later in the afternoon: See the video description: ... the battery in my phone ran flat.

See also these Wikipedia pages: Automorphism   Group automorphism Group isomorphism problem Automorphism group See John Baez's Octonions :  The Fano plane The [much simpler] Cayley-Dickson Construction On Automorphisms, see Hurwitz's Automorphisms Theorem   And that is the reason why the answer to Life, The Universe and Everything is 42 , according to Baez, and I believe him!

This is a followup to yesterday's rambling:  Freya Holmér - Why Can't You Multiply Vectors? See  The Life and Letters of Lewis Carroll  (just below the photograph of George Macdonald and his daughter Lilly ): In November he gave a lecture at a meeting of the Ashmolean Society on "Where does the Day begin?" The problem, which was one he was very fond of propounding, may be thus stated: If a man could travel round the world so fast that the sun would be always directly above his head, and if he were to start travelling at midday on Tuesday, then in twenty-four hours he would return to his original point of departure, and would find that the day was now called Wednesday—at what point of his journey would the day change its name? The difficulty of answering this apparently simple question has cast a gloom over many a pleasant party.

This is really, really interesting. There's a lot here, not just for vintage software buffs. Goes back to Alan Kay ( Smalltalk and The cuneiform tablets of 2015  available from https://archive.org/details/tr2015004_cuneiform ). "Smalltalk was made portable by having each “bag of bits,” called an “image,” that constituted an entire system also carry the microcode for each machine Smalltalk was to run on El . When an image was brought to a particular machine, the appropriate microcode was extracted and executed to create a Smalltalk virtual machine. All the rest of the “bag of bits” was completely machine independent." Even relatively modern systems like Moscow ML end up shipping compiled bytecode with the source. Kay continues: " This led to the somewhat interesting conclusion that one could store media as a “process” if the system that created it were carried along, and if the “microcode” for the system were also supplied. " and " Furthermore, if the “micr

This is an interesting project at the University of Sydney. It's a typed programming language for calculating constructions in abstract algebra.

See  Maki Kato Talking About Verifiable Credentials at VCF East  and  my comment : This is cool. There are a lot of different ways to go forward from here too. One is to be able to handle credit for content creators. Everyone who uses social media, even if they are not themselves content creators, is doing useful work just by paying attention to content creators and integrating the different expressions of ideas that those content creators produce. A system which identifies content creators at a level above the particular platform they use is an essential component of any system that does this. The higher-level system that can be built on top of this identification produces a kind of web of influence, with currents of ideas of that circulate and are developed within it. These vector flows of influence are the basis for any proper system of recommendation which can provide a rational basis for recommending new sources of content, and one that is not so easily subverted by paid advertisi

Subscribe to Serious Science . My comment: It depends upon whether you believe consciousness really exists. If you do then it's irreducible and the problem goes away. If you don't then you have a career ahead of you. The more interesting problem in consciousness studies is what is it that narrows conscious experience to the extent that we start to believe that it is produced by the (human and other animal) brain. There sometimes seems to be a force in the modern world that separates consciousness into individual beings. This is not a natural force but it seems to be produced by human activity of a certain unhealthy (i.e. unwholesome) kind. I think there are physiological explanations that take in the health of society as a whole, including the whole ecosystem in which we live. I think that ecosystem in many places is itself in an unhealthy state. In Sweden this sort of approach to public health is taken seriously, and it works. Subscribe to Jonna Jinton .
