(physical chemistry)
The ability of a substance to form a solution with another substance.



the ability of one substance to combine with another and form a homogeneous, thermodynamically stable system of variable composition made up of two or more components. These systems are formed upon interaction of gases with liquids, liquids with liquids, and other similar combinations. The ratios of the components to one another may be either arbitrary or restricted within certain limits. In the latter case, the solubility is said to be limited.

The solubility of a substance under given conditions is determined from the substance’s concentration in a saturated solution. The solubility of various substances in a specific solvent depends on external conditions, mainly on the temperature and pressure. The effect of pressure on solubility is most pronounced with gases. A change in external conditions affects solubility in accordance with the principle of equilibrium shift (see LECHÂTELiER’S PRINCIPLE). Solubility charts of various substances have been compiled for the most important solvents. Such charts either express solubility as a function of external conditions or simply list the solubility under standard conditions.

Again, this is something that deserves to be considered in another article, but for the time being it is important to recognize that the problem of the "unobservable observer" is an apparently insoluable one and that as a consequence lawmakers and the public need consider how much privacy we are willing to surrender for the sake of crime prevention or public safety.
From the vastly popular X-Files with its "The Truth Is Out There" motto and Agent Mulder's office wall poster reading "I Want to Believe," to last summer's more lighthearted box office hit Men in Black or the youth-market film Spawn, with its graphic and medieval Hell (evil always films better than its opposite, and bad guys get to chew the scenery, which is why angels do better in books than on screen), there seems to be a pervasive longing to be part of something bigger than the merely mundane, seemingly insoluable and often sordid problems of either Cops or the 6 o'clock news.
