Radio was originally a social medium, as early radio sets (each of which could transmit as well as receive) turned cities into giant chatrooms, populated by Morse Code-tapping enthusiasts. But the excitement of this democratic, digital platform did not last, and radio was tamed by corporate interests in the 1920s. The utopian dream of platforms that are open and meritocratic has been reborn in the internet era in the form of bloggi...

At the dawn of the 20th century, chemists dreamed of extracting nitrogen from the air and turning it into a limitless supply of fertiliser. Sceptics thought they were crazy -- it was possible in theory, but it was unclear if it could be done in practice. What happened next changed the course of 20th-century history, and provides inspiration to innovators pursuing a different dream today: sucking carbon dioxide out of the air to ave...

The first ever computer program was written in 1843 by Ada Lovelace, a mathematician who hoped her far-sighted treatise on mechanical computers would lead to a glittering scientific career. Today, as we worry that modern systems suffer from “algorithmic bias” against some groups of people, what can her program tell us about how software, and the people who make it, can go wrong?

Polar exploration was the Victorian equivalent of the space race. Major powers vied to outdo each other, funding expeditions to the most inhospitable parts of the world as demonstrations of their supremacy over nature and each other. Today, the resulting tales of triumph and tragedy hold valuable lessons about what to do—and what not to do—as human explorers plan missions to Mars.

The potato seemed strange and unappetizing when it first arrived in Europe. But it grew into a wonder food that helped solve the continent’s hunger problems. Can its journey tell us what to expect from current efforts to replace animal meat with societally healthier meat alternatives made from plants, insects, or cells grown in petri dishes?

In the early 20th century a new forensic technique—fingerprinting—displaced a cruder form of identification based on body measurements. Hailed as modern, scientific, and infallible, fingerprinting was adopted around the world. But in recent years doubts have been cast on its reliability, and a new technique—DNA profiling—has emerged as the forensic gold standard. In assuming it is infallible, are we making the same mistake again? L...

The Renaissance scholars couldn’t keep up with new information (“Have you read the latest Erasmus book?” “I don’t have time!”) and needed a better way to organize it. Thus came the invention of tables of contents, indexes, book reviews, encyclopedias, and other shortcuts. What kinds of technological solutions might help us cope with the information overload we all experience today? Guests include: Stewart Butterfield, CEO of Slack;...

Some people thought the laying of the transatlantic cable might bring world peace, because connecting humans could only lead to better understanding and empathy. That wasn’t the outcome, and recent utopian ideas about communication (Facebook might bring us together and make us all friends!) have also met with a darker reality (Facebook might polarize us and spread false information!). Should we be scared of technology that promises...

In the Victorian era, plaster casts became a way to preserve important artifacts in 3-D. Now, virtual reality promises to preserve places and experiences. But who decides what gets preserved? And is the technology an accurate recreation of the experience, or does it fool us into thinking we’ve encountered the real thing when we’ve done nothing of the sort? Guests include: Jaron Lanier, VR pioneer; Nonny de la Pena, VR artist; Trist...

In 1969, an anthropologist introduced photographs and films to people in Papua New Guinea who’d never seen themselves represented in media before. It changed their conception of the world. In modern society, social media floods us with imagery at a pace we’ve never encountered before, and powerful video manipulation technology threatens to blur the line between real and fake. Are we the new Papuans, about to be overwhelmed by a who...
