I'm not trying to knock wikipeducation. It's unquestionably a valuable resource. In fact, it's hard for me to imagine returning to pre-net days. What I object to is the somewhat recent and growing phenomenon of people substituting google for their brain. Nothing wrong with using /any resource/ to learn, gather information, check your thinking, etc. But, we should contribute at least some original thinking or analysis when we post (which you BB have done IMO).

My impression was that VC was simply rushing to regurgitate the nearest web-statement that he "thought" "proved me wrong". That is without having actually thought or tried to comprehend my points or any of the resources I referenced. Like he was trying to protect some precious "math ego".

Further, it seems that when this thread began VC was largely ignorant of much of the material now being discussed. Again, nothing wrong with starting off ignorant and learning as you go. At least he is no longer dismissing proofs as "mindless playing with equations" (one of the dumbest things I've heard in a while by the way). No. it's the vociferous way in which he learned, and his inability to admit error and ignorance that was annoying.

> I would not be quite so quick to dismiss VC as a VI.

I didn't think I was quick to do so. It took a few rounds at least :-) And to me every post is a new post as every day is a new day. At any moment, VC could simply admit his mistakes and prior ignorance, apologize for his vociferous learning, stop the dishonest snipping and outright fabrication of false context, and it would be a clean slate as far as I'm concerned. But, I'm not holding my breath and until he does it's draining to continue communication with him.

Then as a fellow engineer, I think you will find Sivia's book most enjoyable and enlightening. It belongs in the family of LSD (Acid) books; being that it is thin, purple, and will expand your mind :-)

(That's not to knock Jaynes' book by the way. His brilliant clear thinking is a delight to explore.)

You are right I didn't suggest that. Having little knowledge and experience with RM I would not presume to make such a suggestion. And from what little I do know of RM, I really don't see myself reaching that conclusion anyhow.

It's strange, my comment was meant simply as an innocuous note of something I personally find interesting.

  "And interestingly, one view of logic is ...

  So ... perhaps conditional probability theory is the   foundation of all :-)"

In light of the whole "one view" and smily thing, the VC attack was ... surprising. I guess it was trying to stroke it's "math ego" and thought it had found a low hanging juicy fruit.

Absolutely. It's interesting you mention such recording. There are numerous scientific databases that would be far more useful had the designers included uncertainty data. One current example is the Gene Ontology (GO), a database of gene - function - location associations. Unfortunately, there isn't even a simple confidence metric assigned to the associations. Such uncertainty information would be invaluable when analyzing various gene networks etc.

I too find probability theory fascinating. At some point, I'd love to hear your impressions of those books.

If that was the case, it would have been great to hear his thoughts about /better/ generalizations. (Note VC I said /your/ thoughts not the /Internet's/ "thoughts".)

Once I thought perhaps we were talking past each other due to different notions of /generalization/. To explore this, I asked VC the simple question: is the gamma function a generalization of the factorial? He dismissed the question as "irrelevant" twice and never answered it.
