I presume the scientology video at the end is just some sort of cruel coincidence - or else inspired advertisement placement - or is it some form of irony?-I totaly agree that many branches of science tend to be sealed off from one another and the general public by their jargon. This is why appointments such as "professor of the public understanding of science" are important and worthwhile developments. I've always tried to maintain a wide overview and not get too drawn into specialisms, although that is unavoidable to some extent. There is no point in knowing everything about one small corner and losing sight of the overall picture. That's why I say science is just a part of philosophy.
