I am white..and I can't dance.. not offended.

What do you mean blacks haven't invented anything?

George Washington Carver has my thanks.. PEANUT BUTTER!!!!
He invented over 300 uses for the peanut along w/ the soybean, sweet potatoes and pecans. Guess one would need to know a bit about "cultivating" those raw materials not to mention a hell alot of science to utilize them.

A plow? How about Henry Blair that invented the mechanical seed planter and corn harvester over 150 years ago.
A black man may or may not have invented the wheel (were you there?) but he has improved it.
Fredrick Jones invented the 2-cycle engine and the air conditioner.
Joseph Gammel invented things for the combustible engine too.

Hey, Daniel Williams did the first open heart surgery.

Thank Henry Sampson for your cell phone while you're at it
