A Martian day lasts 24 hours and 39 minutes, so close to Earth's that rover teams at JPL initially tried to live on Mars time, sliding 40 minutes later each day until crews were showing up to work in the middle of the Los Angeles night

A Martian day runs 24 hours and 39 minutes — close enough to Earth's that JPL rover teams tried to live on Mars time, and far enough that the drift eventually pushed shifts into the middle of the Los Angeles night.

Bristlecone pines growing on the White Mountains of eastern California include individuals that germinated more than 4,800 years ago, meaning trees standing on that ridge today were already centuries old when workers at Giza set the first casing stones of the Great Pyramid

Methuselah, a Great Basin bristlecone pine in California's White Mountains, germinated around 2833 BCE — meaning it was already nearly 300 years old when the Great Pyramid of Giza was completed. It is still alive, still adding rings, still holding needles it grew in the 1980s.

In 1962, one missing overbar in an Atlas guidance equation helped send Mariner 1 off course, forcing range safety to destroy NASA’s $18.5 million Venus mission less than five minutes after launch

On July 22, 1962, a missing overbar in a guidance formula, combined with a radar hardware failure, sent NASA's first interplanetary probe off course and forced Range Safety to destroy Mariner 1 just 293 seconds after launch.

How did a physician in 1854 stop a cholera outbreak that killed 616 people in ten days by mapping deaths on a London street grid and removing a single cast-iron pump handle?

In September 1854, physician John Snow ended a cholera outbreak that killed 616 Londoners in ten days by mapping every death against a single Soho water pump — and unscrewing its handle.

What happened when a low-lying delta nation that lost roughly 138,000 people to a 1991 cyclone expanded coastal forests, shelters and village warnings together?

After a 1991 cyclone killed roughly 138,000 people, Bangladesh built the largest coastal mangrove afforestation programme in South Asia. Three decades on, comparable storms now kill dozens instead of hundreds of thousands.

Psychology

Psychology says people who educated themselves through curiosity instead of classrooms solve problems in a fundamentally different way that formal education can't replicate

Self-directed learning creates neural pathways that classroom instruction simply doesn't, giving autodidacts a cognitive advantage in unconventional problem-solving.

Mars was once a warmer world of rivers, lakes and a thicker atmosphere, but after its internal dynamo died and the planet lost the magnetic shield that helps protect an atmosphere, the solar wind stripped much of its air away over billions of years, leaving the cold desert we see today
