Of course this is only true for normal human eyes.  I understand that 
if you use an ultraviolet transparent lens in the eye, you can 
actually see it.  And of course there are infrared cameras.

My big vote goes for banning the term gravity as a noun, and only 
using it as an ajective, gravitational.  It is very hard to fight both 
tradition and 2nd grade teachers.

While terminology may often mislead, student misconceptions are often 
taught, and also arise spontaneously without any misleading 
terminology.
