He performed Edgard Varèse's Density 21. 5 for solo flute at the Ojai Music Festival in 1962 and participated in Gunther Schuller's Third Stream efforts of the 1960s.

Density 21. 5 is a piece of music for solo flute written by Edgard Varèse in 1936 and revised in 1946.

Allmusic's Sean Hickey says, " According to the composer, Density 21. 5 is based on two melodic ideas — one modal, one atonal — and all of the subsequent material is generated from these two themes.

has no relevance at all to Density 21. 5.

And here, in the last two notes of Density 21. 5 we at last find B paired with its tritone associate.

" This variable relation of the basic motive of Density 21. 5 to the harmonic structure of the piece, and its function in articulating and clarifying the formal design, are exactly what we would expect and take for granted in the relation between motive and background in traditional tonal music.

Most quantitative calculations in modern quantum chemistry use either valence bond or molecular orbital theory as a starting point, although a third approach, Density Functional Theory, has become increasingly popular in recent years.

Density functional methods and semi-empirical methods are variants on the major theme.

Density functional theory ( DFT ) methods are often considered to be ab initio methods for determining the molecular electronic structure, even though many of the most common functionals use parameters derived from empirical data, or from more complex calculations.

So by reducing the number of tracks used and thus capacity, it was possible to further reduce cost-in contrast to Double Density drives used e. g. in IBM PC computers of the day which saved 180 kB on one side ( by using a 40 tracks format ).

Density is an intensive property in that increasing the amount of a substance does not increase its density ; rather it increases its mass.

Density of loading refers to the mass of an explosive per unit volume.

Density was checked as development was occurring.

Density of ice increases slightly with decreasing temperature and has a value of 0. 9340 g / cm³ at − 180 ° C ( 93 K ).

Density and temperature of plasma in the magnetosphere and other areas of space.

Density increases upwards, temperature increases towards the right.

: Density operators are those that are in the closure of the convex hull of the one-dimensional orthogonal projectors.

By 1978 Parr had realized that Density Functional Theory ( DFT ) would be extremely useful in quantitative calculations of chemical and biological systems, especially those with high molecular weights.

In 1989 he and Yang published Density Functional Theory of Atoms and Molecules, now considered the basic textbook on DFT.
