Special thanks to the experts who helped make this video possible:
Brian Enquist, whose work helped inspire this video, for sharing the story behind WBE theory and helping us make its key assumptions and derivation more accurate.

Van Savage, for the generous and detailed feedback that sharpened our explanation of WBE theory, self-similarity, and the current state of the field.

Steven Strogatz, for the insightful conversations, on-camera contribution, and careful reviews that helped us keep the mathematics clear and the story scientifically honest.

Peter Sheridan Dodds, for helping us understand the objections to WBE theory and the debate over three-quarter-power scaling.

And the many other experts who discussed this topic with us as we were developing the script, for their invaluable contributions: Luis Bettencourt, Jayanth Banavar, Aaron Clauset, Juan Rubalcaba, and Douglas Glazier.

Humans, Animals, and the Modern World | Nature Is Not Metal (Bradley Rhydholm)

💾

In Episode 39 of Ethnocynology, I sit down with Bradley Rydholm, the creator of Nature is Not Metal, to talk about wildlife, outdoor education, animal cognition, human relationships with nature, and what it actually means to be human.

Https://www.instagram.com/nature_is_not_metal/

Bradley is an outdoor educator and writer whose work explores the complicated relationship between humans, animals, and the natural world. We talk about the origins and evolution of Nature’s Not Metal, how the internet changed the way we experience wildlife, and why firsthand experiences in nature can fundamentally change the way people see the world.

From there, the conversation gets into animal intelligence and emotion, anthropomorphism, the individuality of wild animals, wolves and dog domestication, cooperation among apex predators, and the idea that nature is simultaneously brutal and deeply nurturing.

We also dive into some bigger philosophical questions: Are cities part of nature? What actually separates humans from other animals? Did agriculture, civilization, or written language change our relationship with the natural world? Bradley discusses environmentalism, Indigenous and Earth-based perspectives, storytelling, rites of passage, and the idea that cultures once possessed social “technologies” designed to turn young people into responsible adults.

A indústria da desinformação no Brasil - Débora Salles | Subsolo #31

💾

O Subsolo recebe Débora Salles, coordenadora geral de pesquisa no Netlab (Laboratório de Estudos de Internet e Redes Sociais da UFRJ).
Neste episódio, o foco está no extremismo político e na desinformação nas redes. Débora Salles explica como as big techs lucram com algoritmos que premiam o engajamento por meio do sensacionalismo e da indignação permanente, transformando a desinformação em indústria. A conversa passa pela "machosfera" brasileira e pela monetização do ódio contra mulheres, pela atuação do agronegócio com greenwashing e pelo debate sobre regulação. Também são abordados os riscos do uso de IA nas eleições de 2026 e os ataques sofridos pelo Netlab.
