What's up in
Mind & Meaning
The psychology of ambition, isolation, and meaning under extremes — and what frontier life teaches us about being human.
The single loudest sound ever recorded was the eruption of the Krakatoa volcano in 1883 — heard from approximately 4,800 kilometers away in the middle of the Indian Ocean — with a sound wave so powerful it traveled around the entire planet four times, was measured on barometers thousands of miles distant, and ruptured the eardrums of sailors aboard ships up to 65 kilometers from the eruption site
In 2003, an Oxford philosopher named Nick Bostrom published an argument that we are statistically more likely to be inside a computer simulation than in original reality — provided any sufficiently advanced civilization runs simulations of its own ancestors, a conditional that has reshaped serious debate about the nature of existence
Smell has a direct neural pathway to the brain's memory centres — and researchers used that to produce a 226% performance gap on a memory test, without drugs or training
Sixty years before ChatGPT, a chatbot called ELIZA was already making people pour their secrets into a computer — and its creator considered that a catastrophe, not a success
There is a documented psychological shift, first described by astronauts who saw the Earth from space, called the overview effect — in which seeing the planet as a single fragile sphere with no visible borders causes a profound and often permanent change in worldview, leaving many astronauts unable to think about human conflict the same way again.
Scientists studying centenarians — people who live past 100 — have found that they don't age much more slowly than the rest of us for most of their lives, but they appear to delay the diseases that kill most other people by an average of 15 to 20 years, in a quiet pattern that suggests longevity may have less to do with slow aging and more to do with avoiding the conditions that cause it
The total number of possible chess games is so large that it exceeds the number of atoms in the observable universe — by some estimates, there are more possible chess games than there are atoms in approximately a trillion trillion trillion universes like ours — and despite this near-infinite possibility space, modern chess engines can now defeat any human grandmaster who has ever lived, in any opening position they care to attempt
The world's longest direct passenger flight is between New York and Singapore — a non-stop journey covering roughly 15,300 kilometers and taking about 18 hours and 50 minutes — and during that single flight, the aircraft crosses 12 time zones, burns approximately 110,000 kilograms of jet fuel, and passes over more of the Earth's surface than the entire span of the Roman Empire at its peak
If the universe is infinite — which current cosmology suggests is genuinely possible — then somewhere out there, beyond the part we can observe, there is an exact copy of the Earth, an exact copy of you, reading an exact copy of this sentence at exactly this moment, because in an infinite universe every possible arrangement of matter must occur not once, but an infinite number of times
The last person on Earth who had been married to a Civil War veteran was still alive in 2020 — Helen Viola Jackson, who married a 93-year-old Union soldier named James Bolin in 1936 when she was 17, and who lived through the entire 20th century into the COVID-19 pandemic as a living link to a war that ended 155 years before her death.
