This chart shows US job openings and the value of the S&P 500. The vertical line shows the release date of ChatGPT. Jobs no longer move in line with the stock market. Fewer workers needed to create growth. Source: buff.ly/YhMttNr

Scraped data from the plot ... gist.github.com/bbolker/d6a6... Scraping is imperfect because the plot is a fairly crappy JPG (hard to distinguish overlapping points). Dashed line is 156 particles per liter, nominal normal/superspreader cutoff (points fall on either side due to scraping error)

I came across "An Editor's Guide to Writing and Publishing Science" by Michael Hochberg (Oxford, 2019). As far as I have read, this is the best book on the subject that I know. academic.oup.com/book/35089 doi.org/10.1093/oso/...
An Editor's Guide to Writing and Publishing Science
Abstract. Scientists must communicate their work through clear writing and publish it where it will be read. To succeed, you need method, but also need to

In cellular automata, simple rules create elaborate structures. Now researchers are working backward — starting with the result to learn the rules behind it. @georgemusser.com, SFI’s 2025 Journalism Fellow, explores how this could reshape computation and self-organization in Quanta:
Self-Assembly Gets Automated in Reverse of ‘Game of Life’ | Quanta Magazine
In cellular automata, simple rules create elaborate structures. Now researchers can start with the structures and reverse-engineer the rules.

Major European cities at the same scale. I to Melbourne (Australia) 18 years ago from Berlin. You can squeeze Berlin around seven times into Melbourne. Density matters. In a low density beast like Melbourne residents pay for much more infrastructure per head. Expensive exercise. HT @xruiztru

Looks more complicated than it is. In our recent study journals.plos.org/plosone/arti... we search for an optimum city size, minimizing both urban carbon emissions and urban heat island (constraint: fundamental allometry). It turns out that given the known UHI parameters such optimum does not exist.
