>>Uhm... and that had to do with what? I don't follow you here.<<
One digit(finger) division is close to the fractional part of the inverse of the fine structure constant. Thus this inverse can be expressed with a small error as:

1/a = sphinx length in whole cubits plus one digit = 137 + 1/28

>>I don't think that you can support that argument. You're assuming that either the Ancient Egyptians knew the molecular weight of the elements (a weight that's assigned, not necessarily a real value) AND that they had a measurement system based on molecular weights... or that the beings who created their measurement system knew this and for some reason or another decided to give them a system that matched the table of elements?<<
What do you mean it is not a real value? If molecules are real then they consist of bonds between nuclei that contain protons and neutrons. Since these protons and neutrons are more or less the same in weight this means that either they defined the proton mass as 1 or the neutron mass as 1. Not logical to assign it to 2 or 3. In both cases the atomic weight would be the same as we use today. It’s all an issue of having discovered Bohr’s model.

>>While leaving a lot of important elements out?<<
I think if you take the whole plan of the pyramid with the internal structures I don’t think they left out important elements.

>>If beings with that sort of sophisticated knowledge wanted to create some sort of "measurement system" that said "we were here" AND if it was based on the table of elements, then they would have done it via radioactive decay products because this is how the elements are formed in the heart of stars.<<
The energy that drives stars is fusion not fission. Thus instead of radioactive atoms like that of Uranus being bombarded by subatomic particles and decaying thus producing energy we have the fusion of Hydrogen atoms to create Helium(at least that’s what happens at stars like out sun). Thus it would be logical if they based their measurement system on Hydrogen.

It seems that the fine structure constant and astronomy was used to define ancient units of measure. Bohr’s radius was used to define a cubit used in Mesopotamia and later on in Egypt. Compton’s wave length of the electron was used to define the Salamis cubit etc. Even if we go on to the dimensions of the atoms themselves we find among other things ancient units of measure like the photon stadium or the Delphi stadium.

Let’s return to the Hydrogen atom and see what three different radius’s are:

Empirically measured atomic radius = (25 +- 5) picometers
Calculated atomic radius = 53 picometers
Covalent radius = (31 +- 5) picometers

Due to the accuracy we cannot be sure but it is surely possible that the above values point to a half royal cubit, a royal cubit , and a foot measure.

>>However, this isn't a practical form of measurement. What's more useful is the length of constants such as light waves (the standard meter is in fact the length of one wave of a particular part of the spectrum. This, however, was decided by "finding a color of light whose wavelength exactly matched that of the meter yardstick that was used as reference"... and not the other way around.)<<
See above.

>>Another question is "why not give the AE's the Whole Shebang?" In other words, instead of handing them a few numbers, give them the whole atomic table and teach them chemistry. Teach them ceramics to construct more complex architecture. Teach them medicine and surgery and sanitary practices. Heck -- why not teach them how to build roads and how to hold back the encroaching desert sands?<<
I don’t think the designers of the pyramids considered the Egyptians their chosen race. They did not want to drastically interfere with human progress either. They were intelligent.

>> they showed up at an AE construction site with the numbers, there is no reason for the AE's to adopt them and pass it along as a cultural practice. If you're speculating a pre-dynastic origin, then why didn't the "giver of a few numbers" also give them better farming practices, irrigation technologies, as well as architectural knowledge so we wouldn't have any crumbly brick pyramids?<<
Since they were very intelligent and advanced they surely would have found ways to persuade or to alter peoples minds to what they had to. We cannot relate to them as God who because of his love he made everybody know everything, eliminated disease etc. That’s not how things work.

>>Erm... this really is a stretch, you know. <<
Maybe. Seth is still a bit vague.

>>So far there's no "proof of concept." Life forms could theoretically evolve with any given chemical base under the right set of circumstances.<<
I’m not so sure about that, are you assuming or have you read about that somewhere?

>>YOU know a bit about chemistry, but I'm not sure that you're a chemist. The speculations you make are based on simple knowledge of the elements and are based on modern measurements and a modern number system. For a life form of another composition or from another world, our modern knowledge would have a very different form (they may number the elements by quark number, for instance, or total number of protons and neutrons, and may or may not include what we call isotopes. They might group things by orbital states, for that matter.) <<
You are right I am not a chemist, I am an Electrical Engineer. The issue with quarks is that whether you take a proton from an Iron atom or a Gold atom they both are going to contain 2 up and 1 down quarks. Thus using quarks in not really going to help you see the differences between elements, it will only make things more complex. It would make more sense if they encoded elements using atomic number or atomic weight(total number of protons and neutrons as you say), and also on the side encoded the composition of each elementary particle in quarks. An isotope is an atom containing a particular number of neutrons and consequently a particular atomic weight close to integer. The mean atomic weight of an element on the other hand is decadic since it is a mixture of different isotopes in different proportions based on it’s abundance in nature. After presenting my diagrams regarding the courses of the GP I think one can see that what was basically encoded is important features – characteristics – or boundaries - see groups of elements – encoded via the atomic number. The atomic weights or isotopes were simply complementary. Also things were left out because they were encoded inside the pyramid – like the niche metals – or radioactive metals in the grand gallery.

>>I think you're at a dead end here. You haven't shown "who done it" (although you attempted a "why this is so"), a consistant system, and a reason for transmitting it. 4 seeds=1 finger width, 28 digits in a cubit makes sense. Having them use a system which involves gods that hadn't been invented at the time the measurement system was derived doesn't really make much sense.<<
The 28 digit relation might be a coincidence. There are a lot of things in nature that cluster around 28 like the moon cycle, the Menstrual cycle etc.
