Atom (measure theory)

In mathematics, more precisely in measure theory, an atom is a measurable set which has positive measure and contains no set of smaller but positive measure. A measure which has no atoms is called non-atomic or atomless.

Definition

Given a measurable space and a measure on that space, a set in is called an atom if

and for any measurable subset with

the set has measure zero.

Examples

Consider the set X={1, 2, ..., 9, 10} and let the sigma-algebra be the power set of X. Define the measure of a set to be its cardinality, that is, the number of elements in the set. Then, each of the singletons {i}, for i=1,2, ..., 9, 10 is an atom.

Non-atomic measures

A measure which has no atoms is called non-atomic. In other words, a measure is non-atomic if for any measurable set with there exists a measurable subset B of A such that

A non-atomic measure with at least one positive value has an infinite number of distinct values, as starting with a set A with one can construct a decreasing sequence of measurable sets

Atomic (song)

"Atomic" is a hit song by the American new wave band Blondie, written by Debbie Harry and Jimmy Destri and produced by Mike Chapman. It was released as the third single from the band's Platinum-selling 1979 album Eat to the Beat.

Song information

Atomic was composed by Jimmy Destri and Debbie Harry, who (in the book "1000 UK #1 Hits" by Jon Kutner and Spencer Leigh) stated "He was trying to do something like "Heart of Glass", and then somehow or another we gave it the spaghetti western treatment. Before that it was just lying there like a lox. The lyrics, well, a lot of the time I would write while the band were just playing the song and trying to figure it out. I would just be scatting along with them and I would just start going, 'Ooooooh, your hair is beautiful.'" The word atomic in the song carries no fixed meaning and functions as a signifier of power and futurism.

The song was produced as a mixture of new wave, rock and disco which had proven to be so successful in their No.1 hit from earlier in 1979, "Heart of Glass". It is written in E natural minor ("Call Me" is written in E♭ natural minor).
