When visiting Berlin, you might notice long stretches of pink pipes weaving through the city. These “pink snakes” span over 60 kilometers, creating a colorful addition to the urban landscape. Their purpose is surprisingly practical.

In 1967, Jocelyn Bell Burnell, a Cambridge graduate student, detected an unusual, repetitive signal while analyzing data from a massive radio telescope. Dubbed “scruff,” the pulses occurred every 1.33 seconds, unlike anything astronomers had seen before.

Born in 1890 in Hagerstown, Indiana, Ralph Teetor lost his sight at age five due to an accident. Despite his blindness, he developed extraordinary tactile skills, which he credited for his ability to innovate. Encouraged by family, he earned a mechanical engineering degree at the University of Pennsylvania.

In 1957, during Operation Plumbbob, the U.S. conducted nuclear tests at the Nevada Test Site. One experiment, Pascal-B, involved detonating a nuclear bomb inside a 500-foot-deep shaft sealed with a heavy steel manhole cover.

In 1822, a white stork was found in Mecklenburg, Germany, with a remarkable feature: an arrow lodged in its neck. The bird, remarkably alive, carried the arrow for miles before being caught.

In January 1770, Benjamin Franklin wrote to botanist John Bartram about a “cheese” from China called “tau-fu.” Franklin included soybeans, which he called “Chinese Garavances,” and a recipe from a British friend, marking the first recorded mention of tofu in America.

Ruth McGinnis was born in 1910 in Honesdale, Pennsylvania. By age seven, she was mastering pool on tables in her family’s barbershop, standing on a soapbox to reach. Her father’s encouragement sparked her lifelong love of the game.

In the early 20th century, Winchester Cathedral faced collapse. Built on a marsh, its foundation began to sink. Cracks formed, and the structure was at risk of falling. Engineers decided the only solution was to underpin the foundation—a task requiring extraordinary precision.

On October 17, 1814, a catastrophic industrial accident occurred at the Meux and Company Brewery on Tottenham Court Road in London. A giant wooden vat, containing over 135,000 gallons of fermenting porter beer, burst due to a defective hoop. The immense force of the escaping liquid caused additional vats to rupture, releasing a tidal wave of over 320,000 gallons of beer.

In the 1960s, Athelstan Spilhaus, a futurist and engineer, envisioned an ambitious solution to urban decay: the Minnesota Experimental City. This self-sustaining urban center promised to eliminate pollution, integrate cutting-edge technology, and house 250,000 residents.
