Hi Slashme!
Thanks for the reply, especially in form of the corrections already done by you and a third party! Your difficulties mentioned above should cause me to revise some of the written stuff; ideally the writing should give any non-physicist a reassuring feeling about the list of instruments that follows, while remaining precise for a physicist. But again I don't want to promise anything in advance. As you can see in other messages, I also had some thoughts about the whole article and how it fits into Wikipedia. (By the way, I was happy to have hopefully found an answer to the question that I found unanswered in many text-books: How do they measure entropy?)
