Hi JT,

Although there are many well educated engineer or
scientist types on this list, there are also a number of
high school and college students on this list as well.
Actually, there is probably pretty much the entire
spectrum represented on this list, both educationally
and experiencewise. I think the key is that, regardless
of your education and/or experience level, with an open mind, you can 
always learn something new. :^)
