The Tech That Seems to Break the Laws of Physics Anna Rothschild
Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for every bit of energy you put in, you get three to five times as much heat out. What wizardry is this? Anna Rothschild investigates the science of heat pumps.
The Dark History of Arsenic Neil Bradbury
No substance has been as constant an ally to insidious scheming as arsenic, the so-called “king of poisons.” In its chemically pure form, it isn’t much of a threat because our bodies don’t absorb it well; it’s when arsenic combines with other elements that things get dangerous. So, how did this substance become such a popular poison? Neil Bradbury digs into the element's sordid and lethal history.
What Makes Someone Vote Against Their Political Party Sarah Longwell
Our brains are hardwired to crave community and belonging — a tribal instinct that drives politics in the United States, says political strategist Sarah Longwell. She shares what she learned trying to convince people to vote against their political party in a recent election and shows why telling a better story about democracy is key to bridging the ideological divide.
Why Did People Wear Powdered Wigs Stephanie Honchell Smith
Wigs date at least as far back as ancient Egypt, where well-regarded hairdressers crafted them into intricate styles. And under certain ancient Roman dynasties, women’s wigs became particularly ornate. Yet it wasn’t until Louis XIII unveiled a magnificent mane in the 17th century that big wigs truly began booming. Stephanie Honchell Smith details the rise and fall of the bewigged fashion craze.
Why Are There Two Tides a Day Elise Cutts
In the 17th century, Isaac Newton offered the first gravitational explanation of tides. As he correctly identified, tides are choreographed by the motions of celestial objects, and Earth’s tides in particular are mostly driven by the Moon. But the precise nature of this relationship is actually quite nuanced. Elise Cutts explains how the Sun and Moon are responsible for the tides.
What Are Warts and How Do You Get Rid of Them Cella Wright
Throughout history, people have attributed warts to contact with things like sea foam, boiled egg water, and, of course, toads. Fortunately, we now know that warts are not caused by toads, but are actually caused by human papillomaviruses, or HPVs. So, how exactly do HPVs lead to warts? And what should you do if you get one? Cella Wright explores the science of these bumpy skin growths.
How the Us is Destroying Young People s Future Scott Galloway
In a scorching talk, marketing professor and podcaster Scott Galloway dissects the data showing that, by many measures, young people in the US are worse off financially than ever before. He unpacks the root causes and effects of this "great intergenerational theft," asking why we let it continue and showing how we could make it end. (Note: This talk contains mature language.)
Why Do so Many Cultures Have Dragon Legends Timothy J Burbery
From the Chinese Loong to the Filipino Bakunawa, the Scottish Beithir and the Greek Hydra, dragons have inflamed imaginations for millennia. Their ubiquity across world mythology has led many scholars to ponder their possible origins. Could it be that tales of dragons were crafted to make sense of violent weather events? Timothy J. Burbery shares what geomythology has uncovered about dragons.
Why Dont We Get Our Drinking Water from the Ocean Manish Kumar
Humans have been transforming seawater into potable freshwater for millennia. Today, billions of people can’t access clean drinking water, and 87 different countries are projected to be “water-scarce” by 2050. So, how can we use seawater desalination to combat water scarcity? And can we do it without further harming the environment? Manish Kumar digs into how scientists are creating freshwater.
This Tool Will Help Improve Your Critical Thinking Erick Wilberding
Socrates, one of the founding fathers of Western philosophical thought, was on trial. Many believed he was an enemy of the state, accusing the philosopher of corrupting the youth and refusing to recognize their gods. But Socrates wasn’t feared for claiming to have all the answers, but rather, for asking too many questions. Erick Wilberding digs into the technique known as the Socratic Method.
Are Insect Brains the Secret to Great Ai Frances s Chance
Are insects the key to brain-inspired computing? Neuroscientist Frances S. Chance thinks so. In this Talk, she shares examples of the incredible capabilities of insects— like the dragonfly's deadly accurate hunting skills and the African dung beetle's super strength— and shows how untangling the mysterious web of neurons in their tiny brains could lead to breakthroughs in computers, AI and more.
