Episode 35: The Great Stink — How Revulsion Rebuilt London In the summer of 1858, the heart of the British Empire became almost impossible to breathe. The smell was everywhere.

Along the banks of the River Thames , the stench was so overpowering that people covered their faces with scented handkerchief...

Episode 34: The Man the Morning Forgot History often celebrates the invention. It rarely remembers the inventor.

Episode 33: The Sky Split in Two — The Tunguska Event (1908) On the morning of June 30, 1908, the forests of central Siberia exploded. There was no warning. No declaration of war. No volcano. No earthquake. Only a blinding flash that turned the sky white, followed by a fireball streaking across the heavens and an explosion so powerful it was heard hundreds of kilometers away. Moments later, a shoc...

Episode 32: The Woman Who Said No — Preventing the Thalidomide Catastrophe Sometimes, history is changed not by a bold invention… …but by a single refusal.

Episode 30: The Echo We Made — A Message to Eternity In the summer of 1977, humanity sent a message into the darkness. Not a distress call. Not a declaration of power. Not a map to hidden treasure. A greeting. Bolted to the side of two spacecraft bound for the stars was a gold-plated phonograph record unlike anything ever created. It carried no scientific data intended for engineers. Instead, it c...

Episode 29: The Longest Fall — A Bomber in the Empire State On the morning of July 28, 1945, thick fog settled over New York City.

Episode 28: The Sacred Breath of Lascaux In September 1940, four French teenagers and their dog stumbled upon a narrow opening hidden beneath the roots of a fallen tree. Curious, they climbed inside.

Towe...

Episode 26: The Bone Wars — Monuments of Spite Some of history's greatest scientific discoveries were driven by curiosity. Others were driven by rivalry.

What began as professional competition in the late 19th century soon escalated into a scientific war. The battlefi...

Episode 25: The Raft — Art's Eternal Indictment of a Shipwrecked State In 1816, a French naval vessel ran aground off the coast of West Africa.

Episode 24: The Wire That Sewed the World Together On a summer day in 1858, a message crossed the Atlantic Ocean in minutes. Until then, the same journey had taken weeks.

The achievement seemed imposs...

Episode 23: The Wind Trade — Debunking the Tulip Mania Myth It is one of the most famous cautionary tales in economic history.

In the 1930s and 1940s, one man set out to prove exactly that...

Episode 20: The Machine from the Deep — The Antikythera Mechanism In the spring of 1900, a group of sponge divers searching the waters off a small Greek island stumbled upon the remains of an ancient shipwreck.

Episode 19: The Man Who Mailed Himself to Freedom In the spring of 1849, a desperate man made an extraordinary decision. He would escape slavery by mail. Not with forged papers.

Episode 17: Unlocking the Silence — Champollion and the Voice of Egypt For more than a thousand years, the monuments of ancient Egypt stood in silence.

His ships carried diplomats, merchants, soldiers, scholars, and gifts to distant kingdo...

Episode 14: The Deadly Punchline — Boston's Great Molasses Flood It sounds like the setup to a bizarre joke. A giant tank of molasses explodes, and a wave of syrup races through a city.

Just after noon, a massive steel storage tank holding more than two million gallons of molasses suddenly rupture...

Hours passed before the truth became cl...
