As I noted in my original response, the answer should be "plain" to
see.

Well put. Now ... borrowing that...

What is to the fourth dimension
as a point is to the first dimension,
as a line is to the second dimension and
as a plain is to the third dimension?

When you have a line, you need 2 points to make from it an abscissa.
When you have two lines (parallel), you need 2 lines to make from it
a square or a rectangle.
When you have a tube with a square profile, you need 2 squares to make
from it a cube.
When you have a tube with a cubical profile, you need 2 cubes to make
from it a 4-dimensional cube. Two free ends in the new dimension must
be closed, always. Plugs in (n + 1) dimensions have n-dimensions.
Write all vertices of 4-dimensional cube as (0,0,0,0) till (1,1,1,1).
You get 16 vectors giving position of vertices. 8 from them have on
the last place 0. They form 3 dimensional cube, the first side of the
higher dimensional cube.

From Synergetics: "The specialists brief on brevity is dubious".

Is gimbal lock a hint that the definition of physical space as three
dimensional instead of four dimensional is just a case of too much
brevity by mathematicians?

The reason I ask is that you can define physical space as four
dimensional like the Synergetics coordinate system, which is from the
tetrahedron, described at:http://bfi.org/node/574
and a method to overcome gimbal lock uses four dimensional unit
quaternions.

And the Pythagoreons might have had the right idea at:

I am not sure, what you want. Your publications on internet are not

I think that the average person ought to know why they put a
four-gimbal-platform on Gemini http://www.hq.nasa.gov/alsj/gimbals.html
because it could mean that physical space is at minimum really
four-dimensional, not three-dimensional.

more than 30 years old. I already published my first results in
scientific journals before this time. Thus you can not claim priority.
Tetrahedrons are only four dimensional planes, only ones from
different n possibilities of multidimensional planes. These planes
form comlexes. You limited yourself only on one posibility.
I was chemist, and I tried to solve some chemical problems. Physical
properties of molecules, as boiling points of alkanes can be explained
using my results, some, and even more important were known even before
I was born. Similarly, most of mathematics I use is older than I am.
The couting of products n^m as sums of products of two polynomial
coefficient was described in textbooks before I rediscovered it and
realized its importance.
