Academics are always debating stuff like this, so a place to go in real life for these conversations would be a university with a strong science department. Online, I’m not sure – my most recent work dealt with applying science. I debate theories with friends and colleagues.

Fluther

I think some kind of academic place is the best place.

I have not found fluther useful as of the late. Which is why I am looking for places devoted to something more specific.

This is a great website, I visit it when I get the chance.

The key word here is “theory”.

So anywhere there is someone to give it.

Back alleys and kitchen pantries ;)there has to be a web-group somewhere,Steve

Give it a try on Fluther.

I should add to my original response that there are a couple of fora I follow relating to engineering:

CR4

and

Eng-tips.com

I agree with mattbrowne. Depending on the theory, you’ll find quite a few experts here.

I also agree and also I am not the one for science.
