If you are bored and want to look up a cool dude: Simon Stevin (1548 - 1620).
His first publication was a buch of tables with interest calculations, showing the true cost of debt to the public at large; something that was a trade secret closely held by bankers up until then.
He introduced the decimal system into Europe, a physics proof here and there, and translated the sciences into Dutch because Dutch is obviously the superiour language spoken by Adam and Eve.
He also made this thing

Nice post, but recently we learned that decimal numbers were introduced much earlier by this Italian accountant.

Failed introduction though if it did not take off 😉. The point was not on who was first to use it; but the fact he wrote a specifc treatise on the subject arguing/promoting its use (De Thiende in 1585). His system did not even use a point but explicitly mentioning the value of the number possition.
So 1.234 would be 1(0)2(1)3(2)4.
Which was rather clunky but i gues it made it clear what he was doing.
Its called Converge evolution.
