Until recently people were scared our planet would be outstripped by the weight of a colossal population. Experts feared that by 2026, there would be so many people that we would be starved of resources, and eat ourselves to death. Ironically we now find ourselves in a world where we’re not
scared about having too many babies, but rather too few. So what happened?
Matt Bevan takes a deep dive into the archives to find out.

Rockets are built to slice cleanly through the atmosphere on the way up. Coming home, it turns out, requires… not turning into a fireball before a bellyflop.
When Space Shuttles reenter Earth’s atmosphere at 17,000 miles per hour, they don’t dive nose first. Instead they turn broadside to the atmosphere, deliberately creating more drag, more friction, more heat. At those speeds, oncoming air compresses into a shockwave hotter than molten lava.
In this episode of Field Notes, Professor Hannah Fry and Michael Stevens explore the strange physics of coming home. Why is leaving Earth easier than returning to it? And what does a small, almost empty black tile reveal about the problem of meeting the world at 17,000 miles per hour?
Along the way, they revisit controversial experiments in human fear, calculate which superhero power would bankrupt you in calories, and reflect on the thin boundary between surface and survival.

In the early 2000s, Sunil Nakrani felt stuck.
Back then, websites crashed all the time. When Sunil noticed this, he decided he was going to fix the internet. But after nearly a year of studying the architecture of the web, he was no closer to an answer. In desperation, Sunil sent out a raft of cold emails to engineering professors. He hoped someone—anyone—could help him figure this out. Eventually, he learned that the internet could only be fixed if he paid attention to the humble honeybee.
This is the story of the Honeybee Algorithm: How tech used honeybees to build the internet as we know it.
Special thanks to John Bartholdi, John Vande Vate, Sammy Ramsey, James Marshall, Steve Strogatz, Duc Pham and Heiko Hamann.
We found out about this story thanks to our friends at AAAS, who run the one and only Golden Goose Awards. The award goes to government funded science that sounds trivial or bizarre, but goes on to change the world. The Honeybee Algorithm won a Golden Goose Award back in 2016 (https://zpr.io/ePxaaYja6YF4). Thank you to our friends there: Erin Heath, Gwendolyn Bogard, Valeria Sabate, Joanne Padron Carney and Meredith Asbury.
