But, but, ... he sputters ... I thought Axiom was supposed to be a system for mathematicians, or at least a system to do mathematics by computer. From that point of view there is barely a telescope long enough to hide the dirty details of the entrails of the computer. ;) On November 22, 2005 5:13

Hi Bill. | Seriously, I have no objections to the suggested location. It would certainly make a change to have something like this away from the traditional haunts of the computer algebra community ie the North Atlantic fringe. Bear in mind that a flight to Austalia from those parts of the worl

Tim, When I read through your email I have to admit that I felt a little depressed. I hope I don't sound too "condescending" by saying this, but I felt like your email moves the discussion of types in Axiom backwards to nearly "high school programming" levels, not even computer science 101... :(
