1 feb 1624 año - Pascal invents first mechanical calculator
Descripción:
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.
