String Theory — The Music of The Spheres? M-theory (Superstring theory) and Brane cosmology.

String theory simplified and poeticised.

Wünschelrute
Schläft ein Lied in allen Dingen
Die da träumen fort und fort,
Und die Welt hebt an zu singen,
Triffst du nur das Zauberwort.
(Joseph Freiherr von Eichendorff)

Magic wand
Sleeps a song inside all things
Dreaming in the spellbound world,
That will waken up to sing,
If you sound the magic word.

(Proverbs. Sentence poem by Joseph Freiherr von Eichendorff)

String theory — science or philosophy?
This theory especially appeals to me because it’s based on a very musical idea — strings, and ‘music’, as Nietzsche put it, ‘is the true Idea of the World’ or in other words ‘world is materialised music’ (Schopenhauer).

This is what string theory is all about: the electrons, quarks and other particles are 1-dimensional oscillating "strings", possessing only the dimension of length. Their vibration determines the particles' flavour (quantum number of an elementary particle, which describes values of conserved quantities in the dynamics of the quantum system), charge, mass and spin. In addition, the superstring theory claims that a "supersymmetry" exists between bosons and fermions — force carriers and matter. But probably its most mind-boggling peculiarity is that such theory requires the existence of several extra unobservable dimensions — M-theory, for instance, puts forward eleven-dimensional space-time.

Quantum Entanglement Questions. Quantum Weirdness.

'We must be clear that when it comes to atoms, language can be used only as in poetry.' — N. Bohr.

What I most love of quantum mechanics is that it is nondeterministic, which means that it’s generally doesn’t predict the outcome of any measurement with certainty. Instead, it just provides the probabilities of the outcomes, so that ‘measurements of a certain property done on two apparently identical systems can give different answers’ — to put it simply, the Truth is unfathomable. That’s how I’ve always perceived the universe and therefore life: governed by the uncertain definition inherent in its very core.

Quantum entanglement, also called the quantum non-local connection, is a property of a quantum mechanical state of a system of two or more objects in which their quantum states are linked together so that to describe one object you have to take into account its counterpart — even if they’re spatially separated.
