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.

Capture the Night - Astrophotography Filter

Meet Tailscale’s DevRel team - A chat about what we’re doing next on this channel

💾

Tailscale’s DevRel team is normally spread across different time zones, so Alex sat down with Kevin Purdy and Ryan Wuller while everyone was together at DevRelCon in Brooklyn. Ryan explains how a career in video production brought him to Tailscale, while Kevin looks back on more than 15 years of technology journalism, open source rabbit holes, and difficult projects that eventually became stories.

Ryan is beginning his journey into self-hosting with a 3D-printed ThinkCenter NAS, while Kevin wants to explore local AI, privacy, and building useful software for yourself. Tell us in the comments what tutorials, projects, and experiments you want the team to make next.

Rebuilding a Roman emperor’s letter

💾

This is a Roman jigsaw puzzle - with missing pieces. More than 150 stone fragments once formed a letter from Emperor Antoninus Pius. Putting it back together means questioning every letter and line.

I built this wood kiln to fire pots fast

💾

After the previous wood kiln design failed to reach temperature, I'm back at it with a new design. Here's the first firing in the new kiln.

Tinker and Think ethos: Combining the manual and cerebral. We cannot separate the mental and the physical, nor treat any endeavor as solely mental or solely physical. But this is precisely how we have come to talk about our world—blue collar vs. white collar, intellectual vs. athlete, book worm vs. adventurer. This is a false dichotomy. This channel promotes an approach that combines manual labor (pottery, carpentry, welding, bricklaying, concrete) with a smart, purposeful attitude (study, reading, science, math, poetry, and meditation). Our minds work best when they engage with our bodies. Our bodies perform best when connected to conscious mental action. Through intelligent manual work, we discover enjoyment, fulfillment, and human flourishing.

O Windows como você conhece está com os dias contados? Neste vídeo, analisamos os vazamentos do "Copilot OS" (Projeto Aion) e os anúncios bombásticos do Projeto Solara na Microsoft Build de 2026.

Microsoft está desenvolvendo um novo sistema operacional totalmente focado em agentes de IA e processamento em nuvem, o que pode decretar o fim dos aplicativos tradicionais .exe e da clássica plataforma Win32.

Entenda como o Win3 e o ecossistema MDEP (Microsoft Device Ecosystem Platform) usam o Android como base para criar dispositivos agênticos que podem substituir laptops e smartphones. Será que a Microsoft está inovando ou cometendo o mesmo erro da era Windows Phone com esses novos hardwares estilo AI Pin e Rabbit R1? Entenda o que muda na rotina dos administradores de TI e usuários comuns com essa migração em massa para a computação "chip-to-cloud".
