138. FROM LEGO TO TRANSCRIPTOMES: EMERGENT STATISTICAL LAWS IN COMPONENT SYSTEMS
M. Osella
15/09/2025, 10:30

Many complex systems exhibit a modular structure: genomes are composed of genes, books consist of words, and technological systems like LEGO sets can be broken down into elementary building blocks. Representing these as component systems—collections of discrete elements—reveals a range of quantitative regularities, often shared across domains. Among these, Zipf’s law is perhaps the most...
