A thoery has circulated for some time that you can prove the existence of anti-gravatational forces through the use of a piece of buttered toast, and a cat.
The experiment is predicated upon the following assumptions:
1). If you drop a piece of buttered toast, it will always land buttered-side down.
2). A falling cat will always land on its feet.
Therefore, to prove the existence of anti-gravtiy, strap a piece of buttered toast (butter side up) on the back of a cat. Hold the cat a few feet off the floor, and let him go. The buttered toast, which MUST land buttered-side down, will be counter-acted by the falling cat, which MUST land feet-first. Since both of these events cannot occur simultaneously, proponents of the theory believe the cat and the toast would simply spin in the air indefinitely.

You are correct. Combination of a late night and too many years from the books. I'd forgot how many elements have an unpaired electron capable of participating in macro alignment: iron, cobalt, gadolinium, dysprosium, and nickel.

I'm not suprised this guy works for Jane's. While they are supposedly the journal of record for military technology and they do a good job of encylopediazing the worlds weapons systems (although the NAval Institute is much better at it when it comes to World Navies), their reporting either consists of rewriting press releases or fanciful reporters such as Cook who write about their "feelings" as if they were a psychic. For much better and documented reporting on military secrets, turn to Popular Mechanics (http://popularmechanics.com/science/military/index.phtml).

These form a basis for what space? The Hilbert space of spherical harmonics.

I need to start reading those books you told me about. :)

Gravity is a spin-2 field. This implies that its coupling to particles has the form of a tensor. Yes. That's what I vaguely remember you posting lo those many months ago!
Yes, this one is worthy of inclusion in the FAQ.
Thanks again for the lucid and concise explanation. I

Orthogonal functions are used throughout physics. The most elementary set is sines and cosines, but there are many more, and each has a different use. Bessel functions, for example, are very useful in describing things that have a cylindrical symmetry.

The Hilbert space of spherical harmonics. You know that the guys in the Math Department spontaneously genuflect whenever they hear than name, don't you?

The color itself. Exactly what is it? Oh this is simple - it's a perceptual effect.

I just spent a semester studying and using the fourier transform, and I am still far from being comortable with it. Unfortunately, I really wanted to get to wavelets.

Several inventors have developed working Anti-Gravity devices. Every patent was bought up by and further research killed by the Brassiere/Plastic Surgeon cartel.LOL........made me shoot coffee through my nose :-)

The smartest weren't Nazi's, though, and if you wish to visit thier post-war home, take a trip to Huntsville, Alabama and check.

81 - LOL - What if you were to toast it then butter the cat's back, which way would it land? Would you have the perfect anti-gravity thing??

The Hilbert space of spherical harmonics. Just to answer the unasked question ("how does an Hilbert space differ from a generic vector space?"), an Hilbert space is a vector space (with an inner product defined on it) which is complete.
Completeness is the property that every convergent sequence of vectors (Cauchy sequence - [please genuflect NOW!]) in the vector space will converge to a vector that is also an element of the space.
The usual example given to illustrate completeness is to consider the infinite convergent sequence:
[3, 3.1, 3.14, 3.1415, 3.14159, ....]
of decimal approximations of pi. Clearly it converges on the value of pi, which is irrational, while every term in the sequence is rational; thus, it is clear that the Rational numbers are not complete (as the Rationals don't contain pi, which is the limit of the convergent sequence), but the Real numbers are (as it contains both the Rationals AND the Irrationals, hence, all convergent sequences of Reals will converge on a value that is also Real.)
In Hilbert Spaces [please genuflect again], the elements (vectors) of the space are often functions instead of numbers, and so one finds that a convergent sequence of such functions converges to a function that is also a vector in the space, and thus Hilbert Spaces [one last time, thank you] are said to be complete.

'Purple' is a subjective designation used to identify a grouping of electromagnetic waves in the spectrum of electgromagnetic frequency; the 'oscillation limits' determine the position on the scale of electromagnetic frequency (I think! ... Physicists, Faraday, longshadow, and others will hopefully correct me here.)

"Wrong oh Mighty Brain-bot. Electricity and Magnetism are well known. They are working on gravity. Give 'em some time."
As electricity and magnetism are well known, what are they? We have an insulator for electricity, do we have an insulator for magnetism?

"Actually, Einstein published his theory of Gravitation. That's what his "General Theory of Relativity" is about."
So what is the the 'theory of gravity'?

So what is the the 'theory of gravity'? And, have we developed an insulator for gravity?

55 - "In science, things are exactly what can be measured/determined about them. For example, an electron is a particle with certain mass, charge, spin, and quantization potential properties belonging to a class of particles known as leptons. That is exactly what "they are." To ask for more goes into the realm of philosophy and metaphysics. The latter realm is generally unproductive and unreliable, imho. " sorry - philosophy and metaphysics are not science. BTW, i heard recently, that they are now postulating that there may be no such thing as an electron, though I can't remember where I heard this, it was in the past several months.
At this point, Cultural Jihad has the best answer to me, however, that doesn't mean it is the final answer, it simply means that we don't know yet. And personally, I feel, that if it is knowable, some day man will know.

I've never in my life seen Hilbert Spaces explained so well. On the other hand, I'd never heard of such a thing.
An unrelated concept is Dilbert Spaces. Those are environments in which all your bosses are dumber than you are but your dog is far smarter.
