Risk compensation

Skydiver Bill Booth 's second rule states that "The safer skydiving gear becomes, the more chances skydivers will take, in order to keep the fatality rate constant."

Gelert by Charles Burton Barber (1884)

Risk compensation

After seatbelt laws passed, Sam Peltzman measured the data: drivers sped up and followed closer, killing roughly the same number of car occupants — but significantly more pedestrians and cyclists.

The Dialectic of Sex

Shulamith Firestone's 1970 'Dialectic of Sex' argued that pregnancy itself — not law or culture — was the root of women's oppression, and only artificial wombs would fix it. She wrote it at 25 and spent her last decades in psychiatric institutions.

CIH (computer virus)

CIH triggered on April 26 — Chernobyl's anniversary — flashing BIOS chips into permanent silence. Written by Taiwanese student Chen Ing-hau in 1998, it destroyed hardware, not just files.

Piss Christ

Andres Serrano submerged a plastic crucifix in his own urine, photographed it glowing amber, and won a $15,000 National Endowment for the Arts award — igniting a Senate floor denunciation by Jesse Helms.

Iamblichus

He rose ten cubits off the ground — glowing gold — while his students watched twice. A Syrian Neoplatonist who made ritual magic philosophically respectable. What do you do with a man who keeps floating?

Gelert

Welsh prince Llywelyn killed his hound Gelert for apparently savaging his infant son — then found the baby unharmed, a dead wolf beneath the cradle. He never smiled again. The grave at Beddgelert still draws visitors.

Zimmermann telegram

German Foreign Secretary Zimmermann telegraphed Mexico in January 1917, proposing a wartime alliance and the return of Texas, New Mexico, and Arizona. British codebreakers intercepted it; Congress voted for war within weeks.

Chevalière d'Éon

The Chevalier d'Éon served Louis XV as a spy, a soldier, and a diplomat — then lived thirty-three years as a woman after a royal decree settled a wager about her birth sex, dying in London in 1810 with the question still unresolved.

Gas mantle

Before electricity, a mesh sock soaked in radioactive thorium dioxide burned inside every middle-class parlour lamp. The mantles crumbled to radioactive dust when touched. Millions were sold; none came with warnings.
