Galileo must be rolling in his grave. Apparently, only four fifths of Americans support the heliocentric view.

Dr. Miller’s data reveal some yawning gaps in basic knowledge. American adults in general do not understand what molecules are (other than that they are really small). Fewer than a third can identify DNA as a key to heredity. Only about 10 percent know what radiation is. One adult American in five thinks the Sun revolves around the Earth, an idea science had abandoned by the 17th century.

I think that this quote, from no less a publication than the New York Times, speaks for itself.
