The topic continues to change, without much explanation! The Btree idea, although initiated by physical concerns, is in fact a logical construction.
Alright, since you seem to want to insist, I'll echo your messages and throw some verbiage at you - It's a two-way street you know, you must offer some information like some of the deep thinkers here who I regularly profit from, in return for your challenges, rather than demanding that your premises be accepted as fact.
I'm starting to think with your references to historical practice that maybe you have not noticed that this is a theory group. Perhaps you could check the handle you are responding to? (EG., are you sending messages to me or to this group? If the former, you can figure out my handle if you reverse the letters in the domain name. I think the regulars I've seen messages from here aren't accustomed to this to and fro'.)
