Invariance is a French magazine edited by Jacques Camatte, published since 1968.
It emerged from the Italian left-communist tradition associated with Amadeo Bordiga and it originally bore the subtitle "Invariance of the theory of the proletariat", indicating Bordiga's notion of the unchanging nature of communist theory. However it soon broke with many of the tenets of Bordigism and Marxism per se, arguing that in the aftermath of May '68 there was no longer any potential for the working class to escape the domination of capital through revolution. Instead it began to take the line that humanity itself had become "domesticated" by the rule of capital and the only solution was to "leave this world", a view which came to influence Fredy Perlman, John Zerzan and others in their development of Anarcho-primitivism. It was this radical shift in orientation which caused many of its critics to observe: "nothing varies more than Invariance ".
Invariance is now in its fifth series and appears sporadically. Every cover features the same image of a tree (held to represent that "all is life"), and on the back the phrase: "Time is the invention of men incapable of love".
Usage examples of "invariance".
It described special relativity as the invariance of physical laws under the Lorentz transformation, and my eyes were opened.
Six symmetries are identified: pitch translation invariance, octave translation invariance, time scaling invariance, time translation invariance, amplitude scaling invariance and pitch reflection invariance.
In particular, pitch translation invariance and time scaling invariance are non-trivial symmetries for the brain to implement, and therefore must serve some significant purpose.
This invariance corresponds to the observation that notes separated by multiples of an octave have a similar subjective quality.
We find that octave translation invariance is not a required invariance of perception.
This contrast between the efficiency of digital and analogue representations appears in the theory of octave translation invariance in Chapter 11.
This pitch translation invariance is so strong that we do not normally regard a piece of music transposed into a different key as being a different piece of music.
Pitch translation invariance means that these different speakers can speak the same speech melody, by translating the speech melody into a range that is comfortable for them.
There are limits to the variation in pitch range that occurs in human speakers, and this would explain why pitch translation invariance in perception of speech is limited.
These ratios are intrinsically pitch translation invariant, so the significance of consonant ratios explains both how pitch translation invariance is achieved, and also why it exists as a precise frequency scaling.
Compare this to pitch translation invariance, which is a global symmetry because the transformations defining the symmetry are translations which must be applied to all of a musical item at once.
Pitch translation invariance is a functional requirement and octave translation invariance is an implementation requirement.
As is the case with pitch translation invariance, achieving this invariance is more non-trivial than we realise.
To achieve time scaling invariance, the brain has to perform a calculation such that its final result is a pattern of neural activity in a neural map which is the same for either the slower version or the faster version of the same rhythm.
Intensity will be pitch translation invariant, for similar reasons to those that cause invariance of intensity in other maps.
