Virginia Tech shooting

Seung-Hui Cho killed 32 students and faculty across two Virginia Tech buildings in 109 minutes, mailing a manifesto to NBC between the first and second attacks. The deadliest campus shooting in U.S. history rewrote federal gun-purchase law.

Cave of Altamira

Painted 36,000 years ago on a cave ceiling in northern Spain, the Altamira bison are so anatomically precise that 19th-century archaeologists accused the discoverer of fraud — they simply could not accept the ancients were capable.

John Law's Company

John Law — a Scottish gambler who killed a man in a duel — convinced France to replace gold with paper backed by Louisiana swampland. Within two years, the word 'millionaire' was coined, then the crash.

Javed Iqbal (serial killer)

Javed Iqbal dissolved 100 boys in vats of acid in Lahore, then mailed a handwritten confession and a diary to police. He was sentenced to be killed by acid in the same vat — a sentence never carried out.

Timur

Outside Delhi in 1398, Timur's men assembled towers of 90,000 skulls. He killed perhaps 17 million people — roughly 5% of the world's population at the time.

Travis (chimpanzee)

Travis, a 200-pound chimpanzee raised as a human child in Stamford, Connecticut, mauled neighbor Charla Nash in 2009, leaving her without a face or hands. His owner called 911 mid-attack, saying: 'He's eating her.'

Killing of Abdulrahman al-Awlaki

Sixteen-year-old Abdulrahman al-Awlaki, a U.S. citizen eating dinner in Yemen, was killed by a drone two weeks after his father. The Obama administration later said it was a mistake. His grandfather asked why.

Tulip mania

In 1637 Amsterdam, a single Semper Augustus tulip bulb sold for 10,000 guilders — enough to buy a canal house. Within three months the market collapsed; bulbs sold for the price of onions.

Bile bear

Bears on Chinese bile farms live for up to 25 years with permanent steel catheters punched through their abdomens, draining bile used in traditional medicine. Many develop liver cancer from the constant extraction.
