I've read some more of this bizarre thread and I can scarcely believe the number of contributors to sci.math who have some problem with concepts such as 0, infinity and the fact that (1/infinity = 0 EXACTLY).
What if someone tried to explain to them that in what mathematicians call 'arithmetic' the 'number' 0/0 is defined as 'undefined'?
I shall not contribute further to this thread - the contributors to it are all mad.
