It means no dimension. One has to have 1 or more dimensions to have
extension in that/those dimensions. You can only have 0 or more extension
if you have a dimension to have the extension in.

Mathematically a scalar is a point or single number, no matter
how long like pi etc.

One asks how thick is a line? One might be tempted to say, zero
thickness, but this is incorrect, as a line doesn't have a thickness
dimension in which to have zero thickness. One has to HAVE a dimension
before one can have zero extension.

A 2x2 2 dimensional piece of gold is not zero thick in the third
dimension. If it were, it would be a 2x2x0 3 dimensional piece of gold,
which would actually be no gold at all as 2x2x0 = 0.

A 2x2 2 dimensional piece of gold however is definitely some gold,
albeit 2 dimensional :)

Same with a scalar, it is not a 3 dimensional 0x0x0 entity, nor
a 2 dimensional 0x0 entity nor even a line of 0 length. It is
a zero dimensional entity.

In APL, a programming langauge, the AxBxC is called the rho of the
object, denoted {a,b,c}.

A 3 dimensional object has 3 members in its rho, one for
each dimension. Thus a {2,3,4} is a 2 by 3 by 4 object.

A 2 dimensional object has 2 members i.e. {2,3} which is
a 2 by 3 object.

A 1 dimensional object has 1 member, ie {3} which is a 3 unit
object.

A 0 dimensional object has 0 members in its rho, its rho
is the empty set. {zip}

Thus a {0,0,0} 3 dimensional object, which is in fact
a nothing of no substance, is not the same as a {zip} scalar
object of definite substance.

People have a hard time picturing a scalar universe, as their
consciousness is capable of only picturing 3D spaces. So they mock
up a 0x0x0 'point' of 3D space and miss entirely what an infinite
scalar universe might be like.

Learning implies Learning with Certainty or Learning without Certainty.
Learning across a Distance implies Learning by Being an Effect.
Learning by Being an Effect implies Learning without Certainty.
Therefore, Learning with Certainty implies Learning, but
not by Being an Effect, and not across a Distance.
