How well do you know your Delta Blues and Quantum Physics?
Some might say that quantum mechanics, via string theory, proves the existence of the Delta Blues, and potentially might offer clues as to where it REALLY came from.
Other than that, they have nothing in common. But what does that have to do with anything? You should probably know something about both of them anyway, if you ever plan on making any real contributions to society. So test your knowledge, and see what you've got to learn.
