1 Feb 1624 Jahr - Pascal invents first mechanical calculator

Beschreibung:

1. If we're not counting the abacus, this (I believe) is the first machine built to do/simplify mental work that was patented and sold.
2. Proved to Europe that this kind of machine was possible and worthwhile to create
3. It's the first mechanical calculator! Things progressed from this point.
