On 5 September 1698, Peter the Great signed one of history’s strangest policy decisions into law: a tax on beards. Fresh from an 18-month incognito tour of Western Europe, the Russian tsar returned determined to drag his nobility into the modern age, one expensive facial hair licence at a time. Meanwhile, on the same date in 2001, a concert began in Germany that won’t finish until 2640. John Cage’s As Slow As Possible plays notes that last for months, with chord changes announced years in advance. In 1661, royal finance minister Nicolas Fouquet was arrested by the real D’Artagnan after throwing a party so lavish it enraged Louis XIV. And in 1970, Formula One driver Jochen Rindt became the sport’s only posthumous world champion after a fatal crash at Monza left him with an unbeatable points lead. Four stories from one date: human ambition, cultural reform, artistic patience, and quiet tragedy.

• Introduction Clara introduces the episode’s central question: what is the most aggressive cultural reform a ruler has ever attempted? The answer involves taxing beards in 1698 Russia, plus a 639-year concert, a real musketeer, and a posthumous world champion.
• Peter the Great and the Beard Tax of 1698 On 5 September 1698, Peter the Great imposed a beard tax on Russian nobility after returning from Western Europe determined to modernise his nation’s appearance. Men who paid received tokens proving they were licensed to keep their own facial hair, while the tsar personally cut sleeves off robes to enforce his vision of progress.
• As Slow As Possible: John Cage’s 639-Year Concert On 5 September 2001, a performance of John Cage’s organ piece began in Halberstadt, Germany. Scheduled to finish in 2640, the concert holds notes for months and changes chords once a year. It started with 17 months of silence and represents an act of trust across centuries.
• The Fall of Nicolas Fouquet On 5 September 1661, finance minister Nicolas Fouquet was arrested three weeks after hosting a party so magnificent it angered Louis XIV. The arresting officer was Charles de Batz de Castelmore d’Artagnan, the real musketeer captain later fictionalised by Alexandre Dumas.
• Jochen Rindt: The Posthumous Champion On 5 September 1970, Austrian Formula One driver Jochen Rindt was killed during practice at Monza. His points lead was so commanding that he became the sport’s first and only posthumous world champion when no other driver could mathematically catch him in the remaining races.
• Outro Clara closes with reflections on human ambition, cultural reform, artistic patience, and quiet tragedy, all compressed into one date in history.

On 4 September 2024, a small asteroid designated 2024 RW1 entered Earth’s atmosphere above the Philippines. What made this event remarkable wasn’t the impact itself, small asteroids burn up regularly, but the fact that astronomers had spotted it nine hours in advance. It was only the ninth time in recorded history that humans had detected an incoming asteroid before atmospheric entry. The same date also marks the 1985 discovery of buckminsterfullerene, a geodesic sphere of sixty carbon atoms that earned its discoverers a Nobel Prize and changed materials science. In 1999, Poland inaugurated a new longwave radio transmitter to replace the Konstantynów mast, once the tallest structure on Earth, which had collapsed during maintenance eight years earlier. And in 1975, East Timorese refugees hijacked an Australian military aircraft in a desperate bid to reach safety as Indonesian occupation loomed. From planetary defence systems that actually work to carbon molecules shaped like footballs, 4 September is a study in human ingenuity, occasional hubris, and the remarkable things we manage when we’re paying attention.

• Intro Clara introduces the episode with a thought experiment about detecting an asteroid nine hours before impact, setting up the story of 2024 RW1 and the broader theme of human preparedness and improvisation.
• 2024 RW1: The Asteroid We Actually Predicted On 4 September 2024, astronomers detected asteroid 2024 RW1 approximately nine hours before it entered Earth’s atmosphere and disintegrated in a fireball over the Philippines. It was only the ninth confirmed pre-impact detection in history, demonstrating the improving capabilities of automated sky survey systems and marking a quiet milestone in planetary defence.
• CTA Clara invites listeners to follow the show and share it with curious friends.
• Buckminsterfullerene: Carbon Gets Interesting In 1985, chemists at Rice University discovered buckminsterfullerene, a molecule of sixty carbon atoms arranged in a geodesic sphere resembling Buckminster Fuller’s architectural domes. The discovery opened new fields in nanotechnology and earned the researchers a Nobel Prize in 1996.
• The Polish Radio Mast That Fell and Rose Again Poland inaugurated a new longwave transmitter at Solec Kujawski on 4 September 1999, replacing the Konstantynów mast that had collapsed during maintenance in 1991. The Konstantynów structure had been the tallest in the world at 646 metres until an incorrectly handled cable brought it down.
• East Timorese Refugees Hijack a Military Aircraft On 4 September 1975, a group of East Timorese people hijacked an Australian military aircraft at Baucau airport and flew to Darwin seeking refuge, as political instability and Indonesian military pressure intensified around East Timor. The occupation that followed would last until 1999.
• Outro Clara reflects on the unrelated events that share a single date, from asteroid detection to molecular discovery to human desperation, and signs off with her signature dry humour about human overconfidence.

On 3 September 1967, Sweden executed one of the most ambitious peacetime logistical operations in modern history: switching from left-hand to right-hand traffic in a single morning. Dagen H, as it was known, required years of planning, military coordination, and the cooperation of 4.5 million drivers. Clare Vale explores how this audacious plan worked, why accident rates actually dropped afterwards, and what it reveals about collective trust. The episode also visits the traditional founding date of San Marino in 301 CE, the world’s oldest surviving republic, examines the 2017 discovery of a Second World War bomb that forced 60,000 people to evacuate Frankfurt, and revisits the launch of eBay on 3 September 1995, allegedly beginning with the sale of a broken laser pointer to a collector. Four stories about human ambition, persistence, unfinished history, and the odd logic of markets.

• Intro Clare introduces the concept of a country switching which side of the road it drives on, overnight, with millions of participants.
• Dagen H: The Day Sweden Switched Sides On 3 September 1967, Sweden switched from left-hand to right-hand traffic. The operation required years of planning, military involvement, and a five-hour road closure. Despite public opposition in a 1955 referendum, the government proceeded. Accident rates dropped sharply in the days after the switch as drivers paid extraordinary attention.
• San Marino: The Republic That Outlasted Everything Traditionally founded on 3 September 301 CE by a Christian stonemason fleeing persecution, San Marino claims to be the world’s oldest surviving republic. It has remained sovereign through centuries of upheaval, never absorbed into Italy, and maintains an unusual dual head-of-state system.
• Frankfurt, 2017: A Very Old Problem On 3 September 2017, authorities in Frankfurt discovered a 1.8-tonne British Second World War bomb during construction work. More than 60,000 people were evacuated in the largest displacement in Germany since 1945. The bomb was successfully defused, but the incident highlighted how wartime ordnance remains a present danger.
• eBay: The Auction That Started With a Broken Laser Pointer On 3 September 1995, Pierre Omidyar launched AuctionWeb, later known as eBay. According to early company lore, the first item sold was a broken laser pointer for $14.83, purchased by a collector of broken laser pointers. The platform became a defining marketplace of the early internet era.

On 2 September 2013, Diana Nyad completed the first unassisted open-water swim from Cuba to Florida at age 64, covering 177 kilometres in 53 hours through shark-infested waters and jellyfish blooms. The same date in 1752 marked Britain’s adoption of the Gregorian calendar, when eleven days simply vanished overnight as the country corrected centuries of accumulated timekeeping error. In 2006, a Siemens locomotive set a world speed record for conventional electric trains at 357 kilometres per hour on German track. And in 1649, Pope Innocent X ordered the complete destruction of the Italian city of Castro, razing it stone by stone and salting the ground. Four stories of human determination, administrative boldness, engineering ambition, and papal fury, all sharing a September date.

• Introduction A woman walks out of the sea in Key West after 53 hours of continuous swimming. Setting up four stories from 2 September across different centuries.
• Diana Nyad Swims from Cuba to Florida At 64, Diana Nyad became the first person to complete an unassisted swim from Cuba to Florida on 2 September 2013, after four previous failed attempts. The 177-kilometre crossing took 53 hours through dangerous conditions including sharks and jellyfish.
• Great Britain Adopts the Gregorian Calendar On 2 September 1752, Britain skipped eleven days to align with the Gregorian calendar, jumping directly to 14 September. The correction ended 170 years of calendar drift from the rest of Europe.
• The Siemens ES64U4 Sets a World Speed Record On 2 September 2006, a Siemens locomotive reached 357 kilometres per hour on track between Nuremberg and Ingolstadt, setting a world record for conventional electric locomotives that still stands.
• Pope Innocent X Destroys the City of Castro On 2 September 1649, papal forces completely destroyed the Italian city of Castro on Pope Innocent X’s orders, salting the ground and erecting a column reading ‘Here was Castro’. The action ended the Wars of Castro.
• Outro Four stories of definitive action, from personal achievement to calendar reform, engineering triumph, and political erasure. Reflecting on different scales of human decision-making.

On 1 September 2021, the last tank of leaded petrol was sold on Earth, ending a century of quietly poisoning the planet. The UN Environment Programme estimated that eliminating leaded fuel would prevent over 1.2 million premature deaths annually and reverse measurable damage to global cognitive development. On the same date in 1974, the SR-71 Blackbird set a transatlantic speed record that still stands: New York to London in under two hours. In 1449, the Zhengtong Emperor of China was captured by Mongol forces at the fortress of Tumu, throwing the Ming Dynasty into crisis until the court simply appointed a replacement Emperor. And in 1996, CargoLifter AG was founded in Berlin with extraordinary ambitions to build a giant cargo airship; the company collapsed, but the massive hangar they built is now a tropical indoor resort. Clara Vale explores the slow victories, impossible speeds, and spectacular overconfidence that marked this date in history.

• Intro What if one of the most harmful things humans ever did was something quiet, ordinary, and sold at petrol stations for nearly a century? On 1 September 2021, the world’s last tank of leaded fuel was sold in Algeria.
• The Last Tank: The End of Leaded Petrol Leaded petrol was introduced in the 1920s as an antiknock agent, despite known dangers of lead poisoning. Geochemist Clair Patterson documented global contamination while facing industry opposition. The UN Environment Programme’s global partnership finally eliminated leaded fuel in 2021, a public health victory expected to prevent over 1.2 million premature deaths annually and reverse cognitive damage at population scale.
• The SR-71 Blackbird Crosses the Atlantic On 1 September 1974, the Lockheed SR-71 Blackbird flew from New York to London in one hour, 54 minutes, and 56.4 seconds at over 1,400 miles per hour. The Cold War reconnaissance aircraft flew above 24 kilometres and exceeded Mach 3. The transatlantic record still stands 50 years later.
• The Tumu Crisis: When the Emperor Was Captured On 1 September 1449, the Zhengtong Emperor of China was captured by Oirat Mongols at the fortress of Tumu. The Ming court responded by appointing his younger brother as the Jingtai Emperor, defusing the crisis. The Zhengtong Emperor was eventually released and later reclaimed the throne in a 1457 coup.
• CargoLifter: The Dream of the Giant Airship CargoLifter AG was founded on 1 September 1996 with plans to build a 260-metre cargo airship capable of lifting 160 tonnes. The company constructed one of the world’s largest free-standing halls at a former Soviet airbase before filing for insolvency in 2002. The hangar now operates as Tropical Islands resort.
• Outro The first of September reveals the long game of history: a century-long poison finally stopped, a 50-year-old speed record still unbeaten, an emperor replaced before ransom could be paid, and a giant airship that never flew but left behind a beach.

On 31 August across three different years, three remarkable stories unfolded. In 2020, scientists published evidence that the New Guinea Singing Dog, long believed extinct in the wild, had been quietly surviving in remote highland valleys all along. This small, fox-faced canid produces uniquely complex vocalisations that could help researchers understand human speech disorders. In 2007, Japanese software company Crypton Future Media released Hatsune Miku, a voice synthesiser that became a global virtual pop star through collaborative fan creativity, performing holographic concerts to sold-out crowds. And in 2006, Norwegian police recovered Edvard Munch’s The Scream and Madonna, stolen two years earlier in a brazen daylight museum raid. Each story reveals something unexpected about persistence, identity, and the gap between what we assume and what actually exists. Host Clara Vale explores how a species can hide in plain sight, how audiences built a person around software, and why stealing the world’s most recognisable painting is considerably easier than working out what to do with it afterwards.

• Introduction A small golden dog in the highlands of New Guinea, a virtual pop star born from software, and one of the world’s most famous paintings returning home. Three stories from 31 August that challenge assumptions about extinction, identity, and art.
• The New Guinea Singing Dog Returns Scientists publish evidence in August 2020 that the New Guinea Singing Dog, believed extinct in the wild since the 1970s, has been surviving in remote highland regions. The species produces uniquely complex vocalisations that harmonise and may help researchers understand human speech. Genetic analysis confirms highland wild dogs are the same lineage as captive populations.
• Hatsune Miku and the Voice That Wasn’t On 31 August 2007, Crypton Future Media releases Hatsune Miku, a Vocaloid voice synthesiser marketed as a virtual pop star. Creative communities worldwide write thousands of songs for her, and she performs holographic concerts to sold-out audiences, becoming a genuine cultural phenomenon built entirely through collaborative fan creation.
• The Scream Comes Home Norwegian police recover Edvard Munch’s The Scream and Madonna on 31 August 2006, two years after armed thieves stole them in a brazen daylight raid at the Munch Museum. The paintings suffered water damage during their absence but were eventually restored and returned to display.
• Outro Three stories from one date reveal how the world is more generous than data sometimes suggests. A dog that never left, a pop star who never existed, and a painting that came home.

On 30 August 1998, two Stanford PhD students modified their search engine’s logo before heading to a desert festival. Larry Page and Sergey Brin added a crude stick figure behind the second ‘O’ in Google, a visual out-of-office notice in case their servers crashed whilst they attended Burning Man. That improvised gesture became the first Google Doodle, launching a design tradition now seen by hundreds of millions daily. Also on this date: scientists announced the discovery of an 800-kilometre canyon hidden beneath Greenland’s ice sheet, larger than the Grand Canyon and carved by ancient rivers before the ice arrived. In 2019, amateur astronomer Gennady Borisov spotted the second confirmed interstellar object passing through our solar system, a comet from another star that gave astronomers months to study before it departed forever. And in 2002, America’s first privately operated subway closed in Birmingham, Alabama, a 300-metre line built beneath a department store to ferry shoppers from car park to shop floor. A day of accidental inventions, hidden wonders, and gloriously niche infrastructure.

• Intro A desert festival, two distracted computer scientists, and a stick figure made of fire accidentally invented one of the internet’s most recognisable design traditions as an out-of-office message.
• The First Google Doodle On 30 August 1998, Larry Page and Sergey Brin modified Google’s homepage logo with a Burning Man stick figure before heading to the Nevada desert, creating the first Google Doodle as a visual notice in case their servers crashed. That improvised gesture launched a design tradition that now encompasses thousands of doodles seen by billions, all starting from two people who didn’t want anyone to panic if the internet broke.
• The Grand Canyon of Greenland On 30 August 2013, scientists announced the discovery of an 800-kilometre canyon beneath Greenland’s ice sheet, larger than the Grand Canyon, carved by ancient rivers and hidden under two kilometres of ice for millions of years. Discovered using ice-penetrating radar, it remains one of Earth’s longest canyons, visited by no one.
• 2I/Borisov: The Visitor From Somewhere Else On 30 August 2019, amateur astronomer Gennady Borisov spotted the second confirmed interstellar object passing through our solar system. The comet, designated 2I/Borisov, came from another star system and gave astronomers months to observe it before it departed towards Cassiopeia, revealing that comet chemistry may be common across the galaxy.
• Leonard’s Subway: America’s Most Niche Underground Railway On 30 August 2002, Leonard’s Subway closed in Birmingham, Alabama. Built in 1972 beneath Pizitz department store, the 300-metre privately operated subway ferried shoppers from car park to shop floor for nearly three decades. The tunnel still exists beneath what is now a food hall.
• Outro A stick figure that started a tradition, a canyon that hid for millions of years, a comet from another star, and a department store that built itself a subway. History is not short of ideas, just short of people paying attention.

On 29 August 1984, two county commissioners in rural Oregon fell mysteriously ill after visiting a religious commune. What followed was the first large-scale bioterrorist attack in American history: 751 people poisoned across ten restaurants as part of a failed election-rigging scheme. This episode also explores the catastrophic opening day of Mainz Cathedral in 1009, when the newly consecrated building caught fire during its own inauguration ceremony; the 1991 murder of Sicilian businessman Libero Grassi, who publicly refused to pay protection money to the Mafia; and Toyotomi Hideyoshi’s 1588 Sword Hunt ordinance, which disarmed Japan’s peasantry and cemented the samurai class system for centuries. Four stories from the same calendar date, each revealing what happens when humans attempt to control the future through planning, power, or sheer bloody-minded refusal to comply. History, as ever, keeps its options open.

• Introduction A seemingly ordinary Thursday lunch at an Oregon salad bar in 1984 turns out to be anything but normal, as a religious commune’s bizarre election-rigging plot unfolds.
• The Rajneeshee Bioterrorism Attack How a charismatic guru’s Oregon commune, led by his secretary Ma Anand Sheela, carried out America’s first large-scale bioterrorist attack by contaminating restaurant salad bars with salmonella, sickening 751 people in a failed attempt to influence local elections.
• Mainz Cathedral Burns on Its Opening Day The spectacular bad timing of Mainz Cathedral’s 1009 consecration ceremony, when the newly completed Romanesque building caught fire on its inauguration day, requiring centuries of rebuilding that produced the structure standing today.
• Libero Grassi The story of the Sicilian businessman who publicly refused to pay Mafia protection money in 1991, writing an open letter that named his extortionists, and was murdered seven months later on his doorstep.
• Toyotomi Hideyoshi’s Sword Hunt The 1588 ordinance that required all Japanese peasants to surrender their weapons, crystallising the separation between samurai and commoners and shaping Japan’s rigid class structure for the next three centuries.
• Outro Four histories of human attempts to control the future, from wisdom to criminal planning, and the determination that connects them all.
