Listened to Mindscape 72 | César Hidalgo on Information in Societies, Economies, and the Universe by Sean CarrollSean Carroll from preposterousuniverse.com

Maxwell’s Demon is a famous thought experiment in which a mischievous imp uses knowledge of the velocities of gas molecules in a box to decrease the entropy of the gas, which could then be used to do useful work such as pushing a piston. This is a classic example of converting information (what the gas molecules are doing) into work. But of course that kind of phenomenon is much more widespread — it happens any time a company or organization hires someone in order to take advantage of their know-how. César Hidalgo has become an expert in this relationship between information and work, both at the level of physics and how it bubbles up into economies and societies. Looking at the world through the lens of information brings new insights into how we learn things, how economies are structured, and how novel uses of data will transform how we live.

César Hidalgo received his Ph.D. in physics from the University of Notre Dame. He currently holds an ANITI Chair at the University of Toulouse, an Honorary Professorship at the University of Manchester, and a Visiting Professorship at Harvard’s School of Engineering and Applied Sciences. From 2010 to 2019, he led MIT’s Collective Learning group. He is the author of Why Information Grows and co-author of The Atlas of Economic Complexity. He is a co-founder of Datawheel, a data visualization company whose products include the Observatory of Economic Complexity.

It was interesting to hear Cesar Hidalgo use the concept of “big history” a few times in this episode. I’m not 100% sure he meant it in the David Christian sense of the words, but it at least felt right.

I was also piqued at the mention of Lynne Kelly’s work, which I’m now knee deep into. I suspect it could dramatically expand on what we think of as the capacity of a personbyte, though the limit of knowledge there still exists. The idea of mnemotechniques within indigenous cultures certainly expands on the way knowledge worked in prehistory and what we classically think of and frame collective knowledge or collective learning.

I also think there are some interesting connections with Dr. Kelly’s mentions of social equity in prehistorical cultures and the work that Hidalgo mentions in the middle of the episode.

There are a small handful of references I’ll want to delve into after hearing this, though it may take time to pull them up unless they’re linked in the show notes.

Replied to Constantly building new memory palaces is annoying by Ywan MüllerYwan Müller (Art of Memory Forum)
Hello, I have a problem and I hope, you can help me. Is there a way to just memorize information with mnemotechniques without doing much work beforhand? My problem is, that I am tired of having to constantely building new memory palaces before I can memorize something. (Reusing memory palaces does not work for me, unfortunately.) Is there a technique where I don`t have to constantely memorize new loci, a technique where I can just put the infos somewhere and review them later? And if so, how does this technique work and is it efficient (a good way to memorize things)? Thanks.
In many modern descriptions of the method of loci, they’re often (unfortunately) described as places that are frequently reused as they would be for memory competitions. This makes them much tougher to use for remembering more useful things in longer term memory. As a result I use a small handful of very specifically selected places for these sorts of short term memory-based journeys. When I’m done with the specific task at hand, I mentally travel back through the journey and wash out all of those short term memories so that I can come back to them in rotation and they’re fresh and clean with many of the memories having faded out with the advance of time. Alternately peg-systems or linked story-systems can be used depending on the items being memorized.

For longer term memory, I prefer to use more everyday locations such as my home (or previous residences, schools, college, etc.) or walks around my neighborhood. This way, as I’m moving about my house, neighborhood, or other frequently visited quotidian places, I’m seeing the accumulated images and regularly re-firming them in my memory. This regular revisiting of them makes them stick in my long term memory much better. For things you want to keep for longer term, revisiting them at an hour, a day, a week, a month, and then three months with occasional annual revisits helps to keep them stored permanently in your long term memory. This method also allows you to add additional information via images over time so that when you’ve read that biography of Abraham Lincoln, for example, you can add any additional information to the loci where you stored him when you may have memorized all of the U.S. presidents in order. Lynne Kelly has a reasonably good description of this in her book The Memory Code where she discusses the timeline of history she’s created in a journey around her neighborhood.

In short, one should carefully consider the type of information one is trying to memorize, the length of time one wants to remember it, and then choose from one of the many methods for remembering it. Experience in doing this takes some time and advanced thought, but in the end will give better results.
