Thanks Peter.
I am strictly an amateur. I don't know how mathematicians understand their complex concepts - how they keep track of it all - it confuses me to no end! LOL.
When people ask me, I tell them that I study only the first four numbers. The interesting thing about these numbers is that they represent all that is real. Raoul Bott proved this with his periodicity theorem.
However, I do believe that there are two interpretations of numbers possible, as Hestenes explains it, and this gives us the negative numbers, because we can regard numerical comparisons three ways: where two quantities exist, one greater than another, there will be a third quantity greater than both of them, ad infinitum.
What happens is that x/y is considered a ratio, but not a ratio of natural inverses, for lack of a better term. The natural inverse of space is time, so we should be careful not to confuse the ratio of orthogonal dimensions of space, with the natural ratio of space/time. The ratio is different, as I try to show in my essay.
If we assume that space and time are simply reciprocal aspects of motion, then whenever we measure space, we are only measuring the space aspect of a past, or contemplated motion. Same thing with time. We can only measure one of the aspects of motion, by combining the reciprocal aspect with it. There is no other way to measure either without the other, because they are simply the two reciprocal aspects of one component, motion.
It follows then, that the use of the Pythagorean theorem in physics can be very misleading, since it involves a space to space ratio, which is not motion, and, since motion is the subject of physics, not space alone, like geometry, we should start off right by studying space and time together (to be clear, physics does study both space and time together, of course, but the numbers of its algebras are not so constituted, leading to ad hoc solutions that are self-defeating in the end).
The use of the Pythagorean theorem is okay when we are dealing with geometry, but we should remember Newton's observation that geometry can only work its magic, when the magnitudes and directions of its spaces are given, based on principles from without. Geometry itself has nothing to say as to the ontology of these magnitudes and "directions."
Instead of using the Pythagorean theorem to study the ratios of motion, or space and time, we need to use the points, lines, squares and cubes of algebra together with the corresponding radii, diameters, areas and volumes of geometry, to understand them.
This is because these two sets of four involve all the dimensions of reality, not just one. Then, when we recognize that these must have an inverse, as demanded by symmetry and the law of conservation, a wonderful new world of possibilities opens up to us.
The best way that I have found to illustrate this concisely is with the following definition of numbers, which is inspired by the tetraktys, or the binomial expansion, generating the first four numbers:
1) (2/2)0 = 0 := 0 magnitudes and "directions" of points
2) (1/2)1, (2/2)0, (2/1)1 = -11, 0, +11 := 2 inverse magnitudes and "directions" of lines
3) (1/2)2, (2/2)0, (2/1)2 = -12, 0, +12 := 4 inverse magnitudes and "directions" of areas
4) (1/2)3, (2/2)0, (2/1)3 = -13, 0, +13 := 8 inverse magnitudes and "directions" of volumes
Which is simply a way of defining the magnitudes and "directions" of the numbers in the tetraktys. These include the reciprocal linear, planar and volumetric magnitudes and the +, -, or 2 "directions" of 1D numbers, the ++, --, +-, -+, or 4 "directions" of 2D numbers, and the ++++, +++-, ++--, +---, ---+, --++, -+++, ----, or 8 "directions" of 3D numbers that generate them. With all these degrees of freedom, a new system of physical theory is possible, based on nothing but motion.
Of course, modern mathematics, and thus physics, has a different foundation. It only recognizes numbers as a set of points, with no "directions." All the higher dimensional numbers are based on exploiting the ad hoc invention of imaginary numbers. These then become rotational units, used according to the Lie Algebras of the different rotation groups, to generate the needed magnitudes. This leads to much confusion. For example, we have no clue as to what quantum spin is, physically, let alone isospin, even though we use these concepts, as if we understood them, because it works out analytically.
I maintain that this is the fundamental error that has caused so much trouble in algebra and physics, but there has been so much gained with the use of imaginary numbers (say all of today's technology!), that not many are willing to go back to examine the assumptions of the foundations in this manner. Only us amateurs (otherwise known as "cranks" or "crackpots" - LOL) dare to risk the folly of such an enterprise.
