In 1805, Jean-Louis Chancel invented the first matches using potassium chlorate and acid, lit on asbestos. Dangerous, but a turning point — fire in an instant, no flint or tinder needed. The spark that led to safety matches.

Ivar Kreuger, the "Match King", built a global empire by trading loans for match monopolies. In 1932, his financial fraud was exposed — a massive pyramid of fake assets. Days before the scandal broke, Kreuger was found dead. Officially: suicide. #MatchKing#history
I suddenly noticed by chance that the square of a natural number is the product of the previous natural number by the next one plus one.
For example
257*255=256*256-1
63*65=64*64-1
45*47=46*46-1
15*17=16*16-1
It's nothing special, but there's something to it...
