John, thank you for that. Over the years he has hinted that he was a
assistant professor at a local college
but as of late I have found it hard to fathom things out as he is so
lacking in the field of physics and electrical
engineering but I gave him the benefit of doubt. So it is quite
possible that like Richard he has his moments.
Like going to the bedroom for a clean shirt. forgetting why he came to
the bedroom so puts on his pyjamas and gets into bed
lesving his wife already to go out while he goes to sleep. I think
they call that senior moments. Well the info given clears a lot of
things up
for me and I shall not continue to guess where his expertize is any
more.

If that "man" (and, I use that term VERY loosely here) has anything to
do with education, whatsoever, one is better off uneducated and ignorant!
