clue=If I decipher correctly, the Hebrew right below the key in this page (90-sep5) reads "mafteakh beyt-david", which means 
approximately "key of the House of David".

carlos txlates the greek
- the greek in fourth level is from Luke, chapter 20, verse 38, and
translates as:

"[...] for all men are alive to him."

clue:  The chemicals are the signature of a group of materials known as 
"high
critical temperature cuprate superconductors." Research in the area was
stimulated by major discoveries in the field in the mid '80s. The current 
theory
of how all this works involves study of issues such as the lattice 
structure of
crystals and the spin of their elementary particles.

These values can be used to  generate what is known as a Sierpinski 
Carpet, made famous by the mathematician Sierpinski in 1916. To visualize 
it, take a sqare and divide it into nine equal squares. Drop out the 
center square. Repeat with each of the remaining squares. ad infinitum. It 
can also be generated mathematically, using the values above. The 
resulting carpet has implications in set theory, topology and generation 
of fractals, as well as possibly other areas I haven't yet discovered.

June 25, 1947
The date the Associated Press ran a story about one of the first UFO 
sightings (the actual sighting occurred on the 24th). The sighting was in 
Oregon, where a Forest Service pilot saw nine unidentified objects flying at a 
speed he estimated to be up to 1200 mph.

Just a guess, but this is referenced elsewhere, and I believe it's the day 
that the group (anyway, I think it's a group) behind all this agreed to 
begin whatever their ongoing endeavor is.

clue:  Dollar to a donut the point about the Oregon sighting of UFOs is correct AND intended to cause
serious people to dismiss them out of hand as UFO fools.  The reference must be to the geographic
coordinates of the sighting.  Huge bet that they could care less about flying saucers and little green 
men but if we think they are nuts, they get left alone to do their project.

clue:  The mathematical definition below the musical score is the Gamma function - a generalisation of the factorial 
function to the complex plane and real numbers. 

Unfortunately they seem to have screwed up, since the actual value of gamma(x) is the reciprocal of the equation to the 
right. (see eg http://mathworld.wolfram.com/GammaFunction.html)

Gordon may be right about a mistake with the gamma but I personally wonder if that isn't deliberately misleading.  For one
example, they might be applying exactly that function and calling "gamma" to the fractal which is to the left.  As soon as an error
is spotted then many people lose interest, that's just human nature.  My thinking is that they intend clever, educated people like
Gordon to dismss it and that way the real numbers can be applied to wherever it is they intended the use.  Mathematics is defined
by agreement and they could agree in advance to whatever suited their purposes.

you asked whether 5/1/72 has historical significance - 9/20/00 indicates it might be the start of this.  Or at least when
the agenda was drawn up.

What key is that short piece of music in?

The key signature has three flats (e flat, b flat, and a flat). It is E flat major.  A well-known work in E flat Major is
Beethoven's Symphony No.3 "Eroica".  I believe this could be from that work.  First performed at a semi-private concert at the
palace of Prince Lobkowitz (its eventual dedicatee) in December 1804, performed in semi-private again at the house of the banker
Herr von Würth, and finally given in public on April 7, 1805 (has anyone ever remarked on the fact that Beethoven's first three
symphonies were all premiered in the first week of April?), the 'Eroica' is a candidate for the greatest symphony ever written and
the work which established the symphony as the major form of musical expression for the 19th century. The first audiences were
astonished at virtually every aspect of the work, particularly its length, which exceed by a considerable margin every symphony had
preceded it. 

"Owsley" was the name of a (or *the*) chemist responsible for a great majority of the LSD extant on the West Coast in the
mid-late 1960s.

"configure the registers as per ADW 1/20/88 #6 sub specie (Guass)"

Guass created a formula to calculate the date on which Easter Sunday would fall (co-incidence? there does seem to be lots of
biblical quotes flying around).
Guass could also refer to Guass jordan Row Reduction

http://people.hofstra.edu/faculty/Stefan_Waner/tutorialsf1/scriptpivot2.html

There are just too many numbers in all of this to discount maths as there are no translation errors.

Rod Info on Guass and the Easter Sunday stuff useful, but the 
ad actually refers to http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Gauss.html - Gauss, a German mathematician.

Whoever wrote that Hebrew text is either being very clever or (more likely) not overly familiar with the language. The two
daled (ie D/d) letters in "David" are poorly formed and could be read as the letter resh (R/r), making the word "Ravir". This would
be meaningless to a Hebrew speaker.

The theory that they (and/or their audience) is unfamiliar with the language is supported by two further facts. The first is that
the text has been written in the clumsy block typeface, rather than in cursive script. The other is that vowels and other pointing
have been included - Hebrew users dispense with these in everyday use, without loss of meaning, as wth a smpl shrthnd systm lk ths.

Re. the Hebrew (already translated as "the key of the house of David") - this is from Isaiah 22:22.

Could the House of David be the Holy Temple... Like the one from which the Wailing Wall is part of?

The Hebrew indeed reads, "Mafteach beit-David", "Key of the House of David".

But there's a clever pun hidden in there.  When I looked up "mafteach", I got:

mafteach (n) - key, *clef*, index, clue

Note: Mafteach can mean "clef" as well as "key", and most of these ads have somehow dealt with music written with clefs.

This supports the theory that the person writing these ads actually knows a good deal of Hebrew, and is perhaps transmitting
information via "mess-ups" or even simply throwing us red-herrings.

Despite the horrendous transliterations of their names, we know lamed-vav-teit.  That spells two words:

lot (n) - cover, envelope, veil
lut (adj) - enclosed, wrapped

But what does either of these have to do with the three dates?

The Key of the House of David looks quite a bit like the key to a lock-box or safety deposit box. Now, Isaiah 22:22 (from
which the Key comes)says (in part) "when he opens, no one shall shut". If the key in this ad is indeed the key to saftey deposit
box #668, it could be a message to the effect that "The implications of the contents of this box are so great that they/it cannot
be reversed."

'The Key is Music'?

Perhaps the title of the song with those notes were some kind of password or
identification to get into a meeting?
