We already changed the superscripts to "S" (My impression was that it should be a very small upper-case "s". Is that right?) I believe we also corrected the variables, I will double-check. I will have Zachary reverse the Zeta function equation and move that sigma down to subscript.

Hi Christian, Here are the (definitive, I hope) Post-Script files for the equations. We've made some changes to eliminate fractional exponents (Medallion I, Equation H) and vector-signs (Medallion VI), and others for scientific reasons; correcting a minus-sign in medallion I, adding a sub zero to Einstein's equation (Equation A), a G to Equation K and a sub A to the first Equation O. I have some free time this weekend, and also Monday if you'd like to meet then.

For some reason I had gotten it into my head that you were still discussing some changes with your colleagues and I was waiting to hear back from you. These changes are a little more extensive than I had expected at this point and will require some time to implement, as they have design implications. We had gone to some lengths to avoid awkward placement of lettering vis-a-vis the seams in the stone. We will have to redo some of that. It may be better, then, to meet right after Christmas, if you are available then. Maybe Thursday? Again, I apologize for not going over this more carefully; it may have been possible to get this done over the weekend, although Zachary had very little time available. Time is starting to be an issue, as I need to have everything set in stone by mid-January when the actual stone starts arriving. Actually, I should have already sent templates to Fred Brownstein to begin the plaster models for the reliefs.

You had mentioned once that you wish we could give it some spatial description. As we were doing it I decided to treat the pathways that cross from migration on one plane to migration on the different plane as  a spacial superposition, as shown here in this picture. It is just a minor detail of the carving treatment, to make some of the lines appear to be crossing over the others in space. (This is extremely tricky carving in this material). I'm sending you this image to check whether..  first: Is my interpretation of the spacial relationship here more or less correct? I am interpreting this diagram to depict two slightly elliptical (but rounder than they appear) migratory patterns on two different planes (at angles to each other) which periodically cross from one to the other, in the same directional patterns, drawn in perspective, that is, both systems are seen at an oblique angle. Second: Are you OK with this treatment? I think it makes the diagram much less confusing, especially from a distance, although it is more difficult to carve. Third: I had no way of knowing, since the width of the line is uniform in all the animations I have seen of these Lorenz systems, which direction this actually goes, the crossovers might of course be flipped here, but I had to pick one way. I felt the important thing was to convey the idea spatially.

I am aware that it appears presently in a couple of places as though it was a single path that splits in two. I am playing with the treatment so that it will not give that impression, but the scale is very small for this kind of stone. There may be a limit to how clear I can make that distinction. I will do my best. I will try to give the appearance of a double line wherever possible. On Mar 31, 2014, at 5:41 PM, Tony Phillips wrote: > Hi Christian, > This from the expert.

Attached is a picture of the wall with the list of our requested short descriptions for a booklet to go with the installation of Christian White's permanent version of the SCGP wall. The request is 250 words or so. My proposal for first drafts is: Peter XIII Supergravity, E-8 4 Newtonian gravity 5 Einstein-GR Martin 6 Schrodinger Eq 7 Dirac Eq 10 Supersymmetry George 0,1,3 Kepler's laws 2 F=ma 9 Yang Mills B Maxwell's eqs. A E=mc^2 E Heisenberg "indeterminacy" (uncertainty?) Tony is asking others to do the remaining ones. The target date is Monday March 23. Maybe we can exchange drafts among ourselves for comments. The ones about Schodinger(6) and Heisenberg (E) we should send by email to Fred (who is in Australia) for comments.
