In Scientific American, Erik Vance reports on how the orb weaver spider — a creature that weighs between .005 milligrams and three grams — has a brain that is just as adept at complex tasks as exponentially larger spiders. This “brain miniaturization” “may hold clues to innovative design strategies that engineers might incorporate in future generations of computers.”
The world’s smallest arachnid, the Samoan moss spider, is at a third of a millimeter nearly invisible to the human eye. The largest spider in the world is the goliath birdeater tarantula, which weighs 5 ounces and is about the size of a dinner plate. For reference, that is about the same difference in scale between that same tarantula and a bottlenose dolphin.
And yet the bigger spider does not act in more complex ways than its tiny counterpart. “Insects and spiders and the like—in terms of absolute size—have among the tiniest brains we’ve come across,” says William Wcislo, a scientist at the Smithsonian Tropical Research Institute in Panama City. “But their behavior, as far as we can see, is as sophisticated as things that have relatively large brains. So then there’s the question: How do they do that?”
“Many of them have chosen to live here and just don’t know how to make a connection,” James Lin, Glide’s senior director of mission and social justice, tells me—they have a neighborhood, in other words, but scarcely know their neighbors. Enter Glide. The church had both the cred and the networks to facilitate an introduction between its oldest and newest residents. As cofounder and minister of liberation, Williams has stood astride poverty and fame for half a century; he marched in Selma, he’s counted the Mandelas and Obamas and Oprahs and Bonos of the world as friends. A newly arrived company looking for an ally on these blocks, or perhaps a broker, could do far worse.
To Felicia Horowitz, wife of tech luminary Ben Horowitz and a devoted Glide supporter, the tech industry has to work extra hard for community acceptance—even as far more insidious local industries mostly escape public reprobation. Chirag Bhakta didn’t mutter about predatory lending bros ruining the neighborhood. At the center, Horowitz sees an abiding tech truth. “We’re outsiders. That’s what it comes down to. We always have been,” Horowitz told me.
