Re: Is there a way for a non-scientist to submit an experiment proposal?

Do it yourself! There's nothing magical about a Ph.D. that forbids people who 
don't have one from doing experiments.

There are lots of amateur scientists out there (the most productive ones are in 
astronomy, geology and paleontology, areas where important contributions can be 
made most easily by patient work with relatively inexpensive equipment); check 
out the "Amateur Scientist" column in every issue of Scientific American. Robert 
Bakker, for example, became world-famous as a dinosaur paleontologist before he 
obtained his Ph.D. -- he was well-known before he had his Bachelor of Science!

If you get interesting results, approach the editor of a professional journal, 
or perhaps look for an organization of amateur scientists in your area. You 
should look for other amateur scientists anyhow.

Even "real" scientists have to do their own experimental work or find for
themselves someone willing to do it for them. There is no place that even
"real" scientists can "submit an experimental proposal to have it done."
There is no substitute for either doing it yourself or
directing/collaborating with another pair of hands and eyes.

A good many ideas, even those of professional scientists, languish for
want
of a pair of hands to do the work. I call to mind my own doctoral advisor,
who always has more ideas than graduate students.

Good luck!
