Shot noise is a type of electronic noise which originates from the discrete nature of electric charge. The term also applies to photon counting in optical devices, where shot noise is associated with the particle nature of light.
It is known that in a statistical experiment such as tossing a fair coin and counting the occurrences of heads and tails, the numbers of heads and tails after a great many throws will differ by only a tiny percentage, while after only a few throws outcomes with a significant excess of heads over tails or vice versa are common; if an experiment with a few throws is repeated over and over, the outcomes will fluctuate a lot. (It can be proven that the relative fluctuations reduce as the square root of the number of throws, a result valid for all statistical fluctuations, including shot noise.)
Shot noise exists because phenomena such as light and electric current consist of the movement of discrete (also called "quantized") 'packets'. Consider light—a stream of discrete photons—coming out of a laser pointer and hitting a wall to create a visible spot. The fundamental physical processes that govern light emission are such that these photons are emitted from the laser at random times; but the many billions of photons needed to create a spot are so many that the brightness, the number of photons per unit time, varies only infinitesimally with time. However, if the laser brightness is reduced until only a handful of photons hit the wall every second, the relative fluctuations in number of photons, i.e., brightness, will be significant, just as when tossing a coin a few times. These fluctuations are shot noise.
In this dance
The saltest kiss to embrace you
And take you to me
A silent opera to entwine you with darkness
As shadows are illuminated
And dusk is dying
You´ll fall from the grace of night
And you fell to me
A silent opera to entwine you with ecstasy
You wither to be reborn in my arms
Why can't I see you
Stand in the circle
The curse chained me
Chained me to the ground
Why can't I reach you
I'm left in the pain
And the flames
Surround me
My voice screaming for you
Despair embracing my soul
And I'm swept away inside a wasteland
All memories are buried in dust
Oh I run, running in blindness
And I'm trapped between the devil and the deep blue sea
I run, running in blindness
And I'm trapped between the devil and the deep blue sea
Why can't I see you
Stand in the circle
The curse chained me
Chained me to the ground
Why can't I reach you
I'm left in the pain
And the flames and the flames and the flames
Surround me
Running in blindness
And I'm trapped between the devil and the deep blue sea
I run, running in blindness
And I'm trapped between the devil and the deep blue sea
Shadow dance
Shadow dance, shadow dance
I'm playing with a fool
Shadow dance
Shadow dance, shadow dance
I'm playing with a fool
Shadow dance
Shadow dance, shadow dance
I'm playing with a fool
Shadow dance
Shadow dance, shadow dance
I'm playing with a fool
Shadow dance
Shadow dance
Shadow dance
Shadow dance
Shadow dance
Shadow dance
Shadow dance
Shadow dance
Oh I run, running in blindness
And I'm trapped between the devil and the deep blue sea
I run, running in blindness
And I'm trapped between the devil and the deep blue sea
I run, run, run, running in blindness
She's whispering my name
In the middle of the night
She says fortune favours the brave
We are the cause of our blindness
My ghost will never leave
I hold your future in my hands
Should I listen to the crying of an eagle?
Why do I hear the calling of the wolves?
I follow her to an unmarked grave
But when I look for her
She's nowhere to be find
I'm all alone in this unforgiving place
This crying child will steal your soul
She's coming home
Reaching out for me
Shadowdancing
In a lightening storm
Should I listen to the crying of an eagle?
Why do I hear the calling of the wolves?
She's showing me the staircase
That leads to the sky
And say goodbye to this life
She's coming home
Reaching out for me
Shadowdancing
