From Ronald Ross to ChatGPT: the birth and strange life of the random walk Jordan Ellenberg
https://youtu.be/08FGB5x090M?si=DFdtl3BrMvSddywL
Between 1905 and 1910 the idea of the random walk, now a major topic in applied maths, was invented simultaneously and independently by multiple people in multiple countries for completely different purposes – in the UK, the story starts with Ronald Ross and the problem of mosquito control, but elsewhere, the theory was being developed in domains from physics to finance to winning a theological argument (really!).
Jordan tells some part of this story and also gesture at ways that random walks (or Markov processes, named after the theological arguer) underlie current approaches to artificial intelligence; he touches on some of his own work with DeepMind and speculates about the capabilities of those systems now and in the future.
Jordan Ellenberg is a Professor of Mathematics at the University of Wisconsin-Madison.

Statistical Laws in Complex Systems
Eduardo G. Altmann
Statistical laws describe regular patterns observed in diverse scientific domains, ranging from the magnitude of earthquakes (Gutenberg-Richter law) and metabolic rates in organisms (Kleiber's law), to the frequency distribution of words in texts (Zipf's and Herdan-Heaps' laws), and productivity metrics of cities (urban scaling laws). The origins of these laws, their empirical validity, and the insights they provide into underlying systems have been subjects of scientific inquiry for centuries. This monograph provides an unifying approach to the study of statistical laws, critically evaluating their role in the theoretical understanding of complex systems and the different data-analysis methods used to evaluate them. Through a historical review and a unified analysis, we uncover that the persistent controversies on the validity of statistical laws are predominantly rooted not in novel empirical findings but in the discordance among data-analysis techniques, mechanistic models, and the interpretations of statistical laws. Starting with simple examples and progressing to more advanced time-series and statistical methods, this monograph and its accompanying repository provide comprehensive material for researchers interested in analyzing data, testing and comparing different laws, and interpreting results in both existing and new datasets.

Future directions in human mobility science
We provide a brief review of human mobility science and present three key areas where we expect to see substantial advancements. We start from the mind and discuss the need to better understand how spatial cognition shapes mobility patterns. We then move to societies and argue the importance of better understanding new forms of transportation. We conclude by discussing how algorithms shape mobility behavior and provide useful tools for modelers. Finally, we discuss how progress on these research directions may help us address some of the challenges our society faces today.
