I'm assuming you've used their search tool?
I just did a quick search at AI using "MarcUK" and found a number of posts by you over there going back to 2002-ish. Since I have no idea what you're on about I don't know what I'm looking for, but there is a thread titled "Anyone studying Quantum Mechanics/Physics????" that looks to be brain-jolting to me.
There were a thousand results, but I'm sure you could sort through them.
For what it's worth, I also used to post at AI (as kscherer—surprise!) but I like this crowd better.
