..goodnight

I want you here tonight, I want you here
Cause I can't believe what I've found.

Rootless Tree - Damien Rice

What I want from you
Is empty your head
They say be true
Don't stain your bed
We do what we need to be free
And it leans on me
Like a rootless tree

What I want from us
Is empty our minds
We fake a fuss
And fracture the times
We go blind
When we've needed to see
And it leans on me
Like a rootless... 

So fuck you, fuck you, fuck you
And all we've been through
I said leave it, leave it, leave it
It's nothing to you
And if you hate me, hate me, hate me
Then hate me so good that you can let me out
Let me out of this hell when you're around 
Let me out, let me out, 
Let me out of this hell when you're around
Let me out, let me out 

What I want from this
Is learn to let go
No not of you
Of all that´s been told
Killers reinvent and believe
And this leans on me
Like a rootless...

So fuck you, fuck you, fuck you
And all we've been through
I said leave it, leave it, leave it,
It's nothing to you
And if you hate me, hate me , hate me,
Then hate me so good that you can let me out, let me out, let me out
Let me out of this hell when you're around


And fuck you, fuck you, I love you
And all we've been through
I said leave it
It's nothing to you
And if you hate me
Then hate me so good that you can let me out
Let me out, let me out, let me out, 
Hell when you're around...(Repeat 4x)

Let me out, let me out, let me out...

It's hell when you're around

...io ascolto rootless tree e lui 9 crimes...andiamo bene!

Karma police, arrest this man: he talks in maths...

eternal sunshine of the spotless mind

"The quote goes, 'How happy is the blameless vestal's lot? The world forgetting, by the world forgot. Eternal sunshine of the spotless mind. Each prayer and each wish resigned.'"

il VIO-LON-CEL-LO...suono IL VIOLONCELLO!

when you see my face hope it gives you hell

mi fa impazzire davvero sta canzone...in Deutschland continuano a passarla alla radio...

come sono adolescenziale...

certo che il cantante...buttalo via ;)

Heisenberg and Noncommutative Algebra

CLASSICAL MODEL: the algebra of observable physical quantities can ben directly read from the group G of emitted frequencies.

Since G is a commutative group, the convolution algebra is commutative.

In reality one is not dealing with a group of frequencies, but rather, due to the Ritz-Ridberg combination principle, with a groupoid:

D={(i,j) : i,j \in I}

having the composition rule

(i,j)*(j,k)=(i,k)

The convolution algebra of the groupoid D is none other than the algebra od matrices, since the convolution product may be written

(a,b)_i,k = \sum_i,j a(i,j)b(j,k)

which is identical to the product rule for matrices.

=> REPLACE THE COMMUTATIVE CONVOLUTION ALGEBRA OF THE GROUP G BY THE NON COMMUTATIVE CONVOLUTION ALGEBRA OF THE GROUPOID D.
