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.
• Outro Clare reflects on collective trust, unfinished pasts, and the strange logic of human decisions across history.
