@chris @eyrea @CriticalCupcake Admitting you and your people made no cultural contributions at all is very brave.

Here's Leonardo Da Vinci with an illustration (from 1480 or so) that clearly shows the potential lift created by a helicopter design. He also built models.

Leo was known to dabble in illustration and painting too. There is no science without the arts. It's not a debate.

Music is mathematics in a way that mathematics couldn't even dream about all by itself.
