With the underlying geometry of the space defined by the semi-symmetric metric connection (SSMC) having been explored, we’re now in a position to examine how Einstein derived his field equations for GR. We will be seeking to follow similar physically-motivated reasoning, such as he used for GR, in our search for candidate field equations which might add electromagnetism to GR based on the geometrical properties of the SSMC.

Nikolas Badminton of the Exponential Minds Podcast and I had a chat a couple of months ago. That interview is now live.
We had a pretty fun conversation. It did meander just a teeny little bit, but it does manage to mention quite a few things as a result: something of the history of my use of the Futures Cone; the levels at which foresight can be implemented; Big History and how I’ve used it to frame the coming civilisational energy transition (i.e., away from fossil fuels); as well as mention of David Christian‘s new book which continues on from Origin Story (which I was reading in manuscript at the time). Of course, there are also some aliens mentioned in there, as is Hoag’s Object. There’s also a little bit on this blog’s current scanning retrospective and the concept of futures intelligence. So, all in all, regular readers won’t find too much that is unfamiliar in the interview, but it might be fun to hear it spoken of. Nikolas did a pretty good job of paring it all back from the very long chat we had! 😉
What I am smiting my forehead over, though, is that I forgot to mention Cal Newport’s 2019 book Digital Minimalism, during the segment where we were talking about using technology with careful intention. My bad! Also, Newport’s podcast, whose name I couldn’t quite remember, is Deep Questions, and it just keeps getting better and better as Cal hits his stride with it. It’s definitely re-ignited my interest in intentional approaches to productivity. Might end up doing a series of posts on that, one of these years…
Anyway, I do hope you enjoy listening to the interview as much I did recording it! Thanks Nikolas!
How DEVO – like Cassandra – saw the future, tried to warn us, and was widely ignored
The title for this post comes from a song lyric by the avant-garde music group DEVO, namely, from the opening song ‘Time Out for Fun’ from their fifth studio album, Oh No! It’s DEVO. By the time that album was released in late 1982, DEVO as a band had spent the better part of a decade promoting the thesis of ‘de-evolution’ – the idea that humanity, rather than progressing, was actually regressing, and was in point of fact not evolving but really de-evolving (which was the origin of their name) to a more primitive state of mindlessly conformist automatons.

In the previous post in this series, I gave the rationale for undertaking this extended (re-)examination of the geometry of the semi-symmetric metric connection (SSMC): essentially, it represents (to my mind) the most ultra-minimalist extension to General Relativity (GR) at all possible – or so I thought back in the early 1990s – given that it introduces precisely one new object – a vector field – as part of the connection.

Many years ago (getting close to 30 now), while doing my PhD (Voros 1996) in theoretical physics on mathematical extensions to General Relativity – and in particular, on Einstein’s own “unified field theory” – I happened across a book by Jan Schouten (1954) called Ricci-Calculus, which was an introduction (by a mathematician) to tensors and their applications, especially to geometrical thinking and analysis.
The question asked in the title of this post is one I have been pondering for the most part of a decade now, ever since I saw the image, shown in Figure 1, of the galaxy PGC54559 (popularly known as Hoag’s Object) in 2010, following several months of thinking about what Kardashev Type III civilisations might look like.
Last year a colleague at the International Big History Association (www.ibhanet.org) asked me how futurists work/think. This was for a book she was writing for high school students on Big History. The final chapters of these types of books tend to focus on the future, hence the request for some ideas from someone who does this for a living. I tapped out a quick, off-the-top-of-my-head answer and sent it off. In thinking about how long since I’ve posted here, I thought I’d better get back into gear, especially as there are some ideas to share coming soon… Here is the essence of what I wrote: Continue reading “How Futurists Work/Think”
