Facts, checked properly.
Myths we put to the test, the mechanism behind a surprising fact, and what the research actually says. Every claim with its source, every time.
The Monopoly Man never had a monocle
He has a top hat and a cane, but no monocle, and he never did. Researchers call this the visual Mandela effect: the same wrong detail, in the same image, across large numbers of people who never discussed it. Your brain stores the type of person and refills the rest from a stereotype everybody shares.
How many hearts does an octopus have?
Three. Two branchial hearts push blood through the gills, and a larger systemic heart sends it on to the body. That third one stops every time the animal swims, because the mantle squeeze that powers the jet pinches its veins shut. It is also why an octopus would rather crawl.
Who actually invented Wi-Fi?
The core technology came from radio astronomers at Australia's CSIRO, led by John O'Sullivan, who were hunting signals from exploding black holes and never found one. What they did solve was how to unsmear a signal that arrives by many paths at once. That is exactly the problem inside a room full of walls.
Is a banana a berry? (And why a strawberry is not)
Yes. Botanically a banana is a berry, because it grows from a single ovary and carries its seeds inside the flesh. A strawberry fails that test: the red part is a swollen flower base, and the little yellow specks on the outside are the actual fruits. The definition is doing all the work, and it is older than the argument.
The app
One fact a day. Then it stops.
No endless feed, no algorithm deciding when you are done. A finite daily stack, every fact sourced, and a review that makes it stick.
