The following is based upon systems of equations found in "Symmetry in Chaos, A Search for Pattern in Mathematics, Art, and Nature" (the second edition) by Michael Field and Martin Golubitsky. They ask the question whether there are aperiodic chaotic attractors that generate symmetric patterns? Can there be order…
This is an elaboration of my submission for the letter detection prize as part of the Vesuvius Challenge in June. It gets technical and esoteric but the first few paragraphs are of general interest…
How the veneer of AI is used to legitimize awful ideas
The story of the infamous disappearance of an Airbus A330 over the Atlantic, and the fundamentally human mistakes which led to the tragedy.
Beneath the utilitarian purpose of computation, computing is also a source of delight and wonder . Software is not just databases and mail merges or SaaS and spreadsheets; it's creative coding and simulated cities , code poetry and bulletin board systems . It's websites that dazzle and iPhone apps that make the heart…
As I’ve posted before and many others have noted , there is a serious problem with lack of adequate replication in many fields of science. The current peer review process is a dreadful combination of being both very fallible and also a huge hurdle to communicating important science.

[This is one of the finalists in the SMTM Mysteries Contest, by a reader writing under the pseudonym Cennfaeladh. We’ll be posting about one of these a week until we have gotten through all th…
There is a ten-foot long alcove in our lower-level hallway — we call it the gallery . This is the one place in our house I can hang whatever I want (i.e., my own art) and switch it out whenever I want. To facilitate this, I installed a hanging system — basically a slotted rail mounted near the ceiling, with sliding…
I live in Seattle on a fairly wooded property. Every summer since we’ve moved here, we end up with swarms of fruit flies in the kitchen. They congregate around the compost bin and the fruit bowl (where there are always lots of bananas). We aren’t slobbish - I do the dishes and wipe down the counters every night, take…
AI and the ruliad in the Wolfram Physics Project provide a new way to consider how alien minds might perceive the world. Stephen Wolfram explains how this artificial neuroscience experiment works.

Programming note: the subscribe link was broken for a while because I am bad at computers (yet another case of "forgot to enable the systemd unit"). It's fixed now. The unsubscribe link was also broken and is now fixed but, you know, maybe that was a feature. Did wonders for reader retention.
Explaining Y Combinator
[Note that this article is a transcript of the video embedded above.] This is the Carlsbad Desalination Plant outside of San Diego, California. It produces roughly ten percent of the area’s fresh water, around 50 million gallons or 23,000 cubic meters per day. Unlike most treatment plants that cle
Like it or not, there’s a clear scientific consensus
June 29, 2023. Some scientists seek to clarify reality, others to mystify it. Physicist David Bohm seemed driven by both impulses. He is renowned for promoting a sensible (according to experts like Einstein, John Bell and philosopher Tim Maudlin) interpretation of quantum mechanics. But Bohm also a
This is the introduction to a four-part series of posts detailing evidence of fraud in four academic papers co-authored by Harvard Business School Professor Francesca Gino. In 2021, we and a team o…
30 Maps to Rethink the World
Large language models are valuable research assistants, especially when they refuse to follow instructions.
AI folklore tells a story about a neural network trained to detect tanks which instead learned to detect time of day; investigating, this probably never happened.
The mathematical field of information theory attempts to mathematically describe the concept of “information”. In the first two posts, we discussed the concepts of self-information and information entropy. In this post, we step through Shannon’s Source Coding Theorem to see how the information entropy of a probability…
Română On the sixth day of our science advent, we would like to talk about a debunked concept in neuroscience. The purpose of this prompt and of science debunking, in general, is not to make fun of how scientists in the past got things so wrong and how we’re so much smarter now. The point […]
So where might we be headed instead?
