Well, I‘m partial to Babbage due to his difference engine and the speedometer (!)
Ditto for that whacky guy Pythagoras and his cult (everybody‘s heard of this Theorum and prime numbers ... we are not worthy ...).
When I was younger I liked DesCartes simply because of the X and Y axis, in addition to geometry.
Fibonacci‘s Sequence always sounded so cool.
And, of course, Pascal and his Triangle (it‘s no Bermuda, but it‘s good enough to have a computer language after him, eh?)
But, hey - who are we kidding? Even though the Countess of Lovelace gets honourable mention ...
Yah gotta love a guy who‘s famous for yelling "Eureka, I‘ve got it" and then running naked through the streets ... the guy who invented the screw, defined Pi and the lever?
Ladies and gentlemen, put your hands together for the lovely and talented ... Archimedes!!!
