Humble apologies, David. I didn't even perceive that step of your reply -
the omission was not deliberate. Now that I understand, your point is
well made. thisw would certainly limit the value such beigs would see in
this kind of instrument.
The mathematical derivation of projecting 3 dimensions onto 2 may be
within their grasp, but there are other more basic solutions. Perhaps
they would devlop interferometry far more ewasily than us. Or perhaps
their display *would* be three dimensional, with the third dimension
Even if they understand this kind of quasi-2-dimensional display, 2-d
representation would be incomplrehensible - the concept of an outline as
a picture, for example.
You raise some other truly profound points in your note - which I do not
have time to consider this morning. I'll try to get to them later today
if at all possible. You are suggesting a complete new 'take' on maths
which they might consider the natuiral order of things - isometric with
our own maths, of course, but possibly so different it would take us
years to begin to fathom it. Interesting...
