...and, to have radio communications with the civilized world when in the heart of an equatorial jungle, one must physically transport a radio to the remote location.
still beats humping back and forth with handwritten notes, no?
a total suppostition - what if there is a specific kind or range of entanglements which are simply easier or more durable or more useful than the others? what if there is what amounts to a "universal frequency" for entangled communication?
I cannot even begin to have serious thoughts on the matter, lacking anything close to even a beginner's knowledge on it, but it makes for pleasant fantasy.

You're in good company: as (I think) Feynman said, nobody understands quantum mechanics...you just get used to it. I am much more used to the idea since I began wearing the official Schrödinger's Cat T-shirt. If I spin on axis real fast in front of a mirror, I can read both front and back simultaneously.

Purely mathematical and somewhat philosophical. It's an interesting question. Why is i sufficient? (Run your spell&grammar-checker on this.)

hrmn... no patterns in nature...
can't agree - we observe and describe patterns, but they were extant before we did so.

well, if you had the right materials, you might be able to construct a radio locally.

why can data NOT be transmitted in this manner?

There are two others. There are always three cube roots. You might have fun finding them.

I mean, -1^3 = -1... Yup. If the number of roots is odd, it doesn't generate anything "interesting" that would provide a basis for an orthogonal direction, as "i" does in the case when you take the SqrRoot(-1). "i" is used to define an orthogonal dimension wrt to the real number line, together forming the basis of the Complex Plane.
To: Physicist
I was under the assumption that the likelihood of the "dead" state would be dalculated according to a function which started with a value of 0 at time 0, and apporaches 1 at time infinity. The speed of the approach to one is determined by the characteristics of the actual material. But, this is a probablility and is not the same as actual reality which can only be determined by observation.

And if you rotate your phone 90 degees, you can dial an imaginary phone number.

ok, give me an illustration, so that I (might have some chance to try to) know what you are talking about: What are the other cube roots of, oh, 27, besides 3?
and no cheating... X3 and Y3 and Z3 have the same numeric value ;)

Something to consider--we have observed patterns in nature since we became conscious several eons ago. The patterns we have observed are always replaced by new patterns, so cannot have been produced by nature. It was only a century ago that the ether was replaced by relativity, and relativity is a mathematical description of an illusion.

we observe records of patterns which long predate our rise.
QED: patterns existed prior to our rise and subsequent description of the patterns.

Quaternions were quite an innovation, but turned out to be not particularly useful and were abandoned--until a few years ago. They are back, especially in graphics.

That's the clearest explanation of Schrödinger's cat I have ever read.
Thanks.

x**3-1=0 is the equation we need to solve. -1 is one solution.
(x**3-1)/(x-1)=x**2+x+1 so we solve this by the quadratic formula.
x=(-1+Sqrt(-3))/2 or (-1-Sqrt(-3))/2
These are the others cube roots. Multiplying by 3 gives the cube roots of (-27).

We observe. There is a jump between sensing and perceiving. The jump occurs in our consciousness--the sensory input is primary data; the analysis, however faulty, is an attempt to make a pattern out of the data.
