Sound of Silence!

Sometimes I wonder about the imagination ( and many times their interpretations ) of poets and writers ( To include the modern day singers. In a broad sense "Artists" in which I include the "Physicists" . ) To start with " Ravi kaanchanicho kavi kaanchune kadha...
Three examples :
1 ) Jonathan Swift in his third part of Gulliver travels he is able to predict the neptune and its satellites with their period of rotation with fair amount of accuracy.
2 ) Keats( I dont remember whether its Shelly whoever it is...) " A bold lover... thou can't kiss her... " a line saying about painting on the pot where a king sees beautiful woman. To a non-physicist. It might not matter. Or may be they interpret it in another way. In physicist point of view its like this. There are some other dimensions missing. here in this case is case the time dimension. Without that time dimension he can't kiss her. And this problem in now a days theoretical physics is taken rather seriously and they put forward not 4 ( x,y,z,time ) but 11 or may be 16 dimensions. So without exploring those extradimensions we can't describe the Universe exactly. Extra dimensions? You can say no way maaaan. But see.... observe from a very large distance a straw. It appears to be a line. But when we observe it from a a point near to it, its like a 2d surface curved around. Also if the straw was very very very large, we observe it to be a flat surface like earth. So the dimensions which we don't are curled up in small dimensions either can't measure or very large values which we virtually feel to be in flat in that dimension.
3 ) Sound of Silence : sung by Simon and Garfunkel. Its a oxymoron. Sound is absnce of silence. Silence is absence of sound. But yeah....this kind of term exists in Physics. The so called Vacuum fluctuations or Quantum fluctuations. Which says that there is nothing like classical vacuum. There is always some truly speaking not some but infinite energy in the free space which we treat it as vacuum. These can be seen as a manifestation of Heisenberg's( Einstein : ...I'm at all events convinced that He doesn't play dice . Bohr In reply to it : But still it cannot be for us to tell God, how he is to run the world. ) Uncertainity Principle like Ferromagnetism which is manifestation of Pauli's principle. These vacuum fluctuations are responsible for many effects which one example is Laser ( without these spontaneous emission cannot occurs and without these stimulated radiation cannot be produced. ) and LED. Also Casimir effect.

To end it up
Pal Adrian Maurice Dirac : It seems that if one is working from the point of view of getting beauty ib one's equations and if one has a really sound insight, one is on sure line of progress.
So if you are able to appreciate the beauty, symmetry( or antisymmetry ) of the nature and try to put it int the form of equation then suddenly most of the disorder falls into order.
