The Cosmic Microwave Background (NASA 2010)
I.
Readers may recall the big hoo-ha created by physicists Sokal and Bricmont back in the late '90s when they criticised (and indeed mocked) philosophers and postmodern theorists for their misuse - as they saw it - of very precise scientific and mathematical concepts.
Their book - first published in French as Impostures intellectuelles (1997) - polarized opinion, with those in the scientific community largely supportive, whilst opponents in the humanities argued that Sokal and Bricmont lacked understanding of the work they subjected to analysis and of how concepts are malleable and can thus be subtly (and sometimes playfully) reworked within different contexts and that doing so isn't necessarily a sign of charlatanism, ignorance, or pretension on behalf of thinkers such Baudrillard, Deleuze, and Irigaray.
Nor is this reworking simply a sign of cognitive relativism and anti-scientific prejudice within European philosophy (though that's not to deny that such may exist). Using scientific terminology within a non-scientific context doesn't deny the original technical meaning, it expands the meaning and/or transfers it into a new environment (the terms are revealed as having a metaphorical component and capacity).
Sokal and Bricmont may find this peculiarly offensive for a number of reasons, but then, on the other hand, some of us may find their linguistic puritanism and Francophobia equally objectionable. As Derrida rightly pointed out at the time, science and philosophy have long discussed their differences, but never with such an ugly emphasis placed on the nationality of individuals.
(Derrida also stated, for the record, that there was neither relativism
nor a naive rejection of reason in his work and hoped that in the future
the debate might be pursued more seriously and with greater dignity: "at
the level of the issues involved" [1].)

So why did I bring all this up once again? Well, because I have just been reading an interview with Peter Sloterdijk in which he mentions his fondness for the concept of background radiation ...
Now, as Sokal and Bricmont would be quick to point out, this is a scientific term which refers to a measure of the ionising radiation present in the environment at a particular location originating from a variety of sources, both natural and artificial.
And as I'm sure they'd be equally quick to point out, Sloterdijk is a philosopher and cultural theorist - not a physicist - and, worse, he's a German thinker in the tradition of Nietzsche and Heidegger, so really shouldn't be allowed to use the concept of background radiation at all.
Nevertheless, use it he does and in his own unique way which, hopefully, illustrates what I was saying above:
"I really like the concept of 'background radiation', especially applied to cultural structures. Astrophysicists may rack their brains about what background radiation means in cosmological terms. However, that there is something like cultural radiation from a darkened background - patterns of order that are so deeply hidden in the oldest things, so strongly embedded in the sediment of what we think is self-evident that they seem to escape any reflection [...]" [2]
As an interesting example of this cultural background radiation, Sloterdijk points to the fact we still use a technique of temporal ordering that was first developed in ancient Babylon:
"We live in the Babylonian week apparently naturally, without thinking that it was predicated on a theology of the Heavenly Seven, that is, on a kind of septemtheism, which means the worship of seven deities. The seven day week is a cultural creation because, unlike the day, the month and the year, it has no cosmic basis, but represents a freely made decision that fixes the arrangement of social time." [3]
In sum: Sloterdijk nicely demonstrates how you can borrow a term from one
discipline and redefine it within another - without in any way harming
the original meaning or preventing its continued usage by others.
