  • With Heart: Emoji Interpreters

    In 1995, a tiny pixelated heart on a Japanese pager became the most important thing on the screen. When it disappeared, young people left. One man never forgot and went on to draw the original 176 emoji.     

    In this episode:

    • Pocket Bells and goroawase: how Japanese teenagers turned numbers on pagers into a language of their own
    • The heart: the small symbol on NTT Docomo's Pocket Bell, and what happened when a new business model took it away
    • Shigetaka Kurita: the former pager salesman with no design training who was given five weeks to draw the original 12x12 pixel emoji for i-mode
    • Unicode and HEAVY BLACK HEART: how emoji became part of a shared standard in 2010, and why the red heart carries such a strange formal name
    • The Museum of Modern Art: how Kurita's designs became part of MoMA's collection, and why an emoji means whatever we make it mean

  • Inflection: The Voder, Voderettes, and Voice

    In the summer of 1939, at the New York World's Fair, a woman sat beneath a three-story mural of a shouting man and shaped raw electricity into a human voice.   

    In this episode:

    • Homer Dudley: the engineer who reimagined the human voice as a handful of numbers at Bell Telephone Laboratories
    • The Voder: The human-driven machine built to imitate the effects of the human vocal tract
    • The Voderettes: 24 telephone operators chosen from hundreds who practiced for more than a year to play the Voder 
    • Helen Harper: The Voder virtuoso who trained the other Voderettes to perform feats of mental gymnastics to make the machine speak.

  • Dead Reckoning: The Globus and Voskhod 2

    In March 1965, two Soviet cosmonauts fell out of the sky into a frozen forest in the Urals, trapped inside a cramped capsule hundreds of kilometers from rescue. Their survival, and their journey home, relied on an intricate mechanical computer made of aluminum, clockwork, and paper. 

    In this Episode

    • Laboratory 47: the branch of the Soviet Flight Research Institute in Zhukovsky, run by engineer Sergei Darevsky
    • The Globus: the indicator of position in flight, a paper-wrapped aluminum globe run by differential gears and cams with orbital curves ground into their edges
    • Dead reckoning in spaceflight: why the instrument knew nothing it wasn't told and what that meant for the cosmonauts
    • Voskhod 2: Pavel Belyayev and Alexey Leonov, a spacewalk that nearly ended in catastrophe, a failed automatic descent, and the forty-six seconds that decided where they landed

  • Cry Wolf: Waiting and Seeing with Camera Traps

    Since the 1890s, we've been building machines that wait in our place, in the dark, for something to move. This is the story of how a thread across a trail became a sensor that can feel heat, and what we learn when we really look. 

    In this Episode

    • George Shiras: the Michigan naturalist and early wildlife photographer who rigged the first trip-wire camera traps in the 1890s
    • Pyroelectricity: the physical property that lets a crystal generate a faint electrical charge when its temperature changes
    • The Fresnel lens: how a design borrowed from 19th-century lighthouses now focuses invisible infrared light onto motion sensors in camera traps, driveway floodlights, and burglar alarms
    • The Haíɫzaqv Nation's coastal wolfs: How a camera trap on the coast caught a wolf doing something scientists didn't know wild wolves were capable of
    • Machine learning classifiers: how citizen scientists trains algorithms to sort real animal sightings from the false alarms 
    • Colorado's gray wolf reintroduction: the closely monitored 2023 reintroduction effort and recent events

  • Tidal Forces: Calculating D-Day

    In 1944 the Allies needed to know exactly what the water would do on a coast called "Position Z." So a deaf mathematician and six young women in a basement near Liverpool calculated the future.  

    In this episode

    • Arthur Doodson: the deaf mathematician at the Liverpool Tidal Institute, the world's leading authority on tides, who guessed he was predicting a Normandy landing and said nothing
    • Six women working as Computers: hired for their diligence, skill with numbers, and neat handwriting, they ran the harmonic analysis and operated the tide-predicting machines
    • The tide predicting machines: the Bidston Kelvin machine and the Roberts Légé machine, analogue computers made of brass, gears, and pulleys.
    • D-Day: The largest seaborne invasion in history

  • Entropy Hunters: Random Numbers and Chaos Machines

    This is the story of how we learned to fake the most natural thing in the world. What it cost us. And the strange places we still go, even now, to steal a little of the real thing back.

    • Bernice Brown: the RAND statistician whose job was to hunt for a pattern inside a million digits and sign her name only when she could not find one
    • The electronic roulette wheel: RAND's random number making machine and why its raw output drifted into bias
    • Stanisław Ulam: the mathematician whose card game in a hospital bed became the Monte Carlo method, and the reason anyone needed randomness by the millions in the first place

  • Silent Agreement: MIDI and What We Hear in the Wires

    Sheet music has always been an invisible treaty. A shared language that belongs to everyone and no one. But fifty years ago, as musicians began shaping sound out of raw electricity, that treaty fell apart.



    In this episode

    • The Broken Treaty: Why early synthesizers from different manufacturers couldn't talk to each other, and the resulting landscape of incompatible voltages.
    • The Unlikely Alliance: How Dave Smith in the US (Sequential Circuits) and Ikutaro Kakehashi in Japan (Roland) looked past corporate rivalry to build a universal standard.
    • The Birth of MIDI: How microscopic 1981 microprocessors forced engineers to shrink the musical universe into elegant, lightweight digital sentences.
    • Juan Atkins: the Detroit musician whose work sparked the global rise of techno music.
