To begin with, I object: the "verbosity" of the guest was IMHO excactly apropriate. It was a very interesting journey through mathematica, and not only your special field, integration, but a wide range of fascinating topics and recent developments. Surely I will come back and listen again to some passages of the Podcast. As you might remember, recently I found a bug in a special complex path integral (comp.soft-sys.math.mathematica) and, among others, you responded recognizing the bug. In your podcast you made an important strategic remark: if there is a result given for an integral then it is correct, if Mathematica think the result might be incorrect, then no answer is given. I like this strategy, but, unfortunately, the newsgroup found a counter example. Different good looking results which are wrong. Finally, may I ask you to give me a hint on some white paper on integration in Mathematica? I'd like to go into some more depth mainly on branch cuts of 2F1 etc. Thanks in advance and best regards, Wolfgang
