Factor Analysis in Physical Sciences
Factor analysis has also been widely used in physical sciences such as geochemistry, ecology, and hydrochemistry.
In groundwater quality management, it is important to relate the spatial distribution of different chemical parameters to different possible sources, which have different chemical signatures. For example, a sulfide mine is likely to be associated with high levels of acidity, dissolved sulfates and transition metals. These signatures can be identified as factors through R-mode factor analysis, and the location of possible sources can be suggested by contouring the factor scores.
In geochemistry, different factors can correspond to different mineral associations, and thus to mineralisation.

Famous quotes containing the words factor, analysis, physical and/or sciences:
“Children of the middle years do not do their learning unaffected by attendant feelings of interest, boredom, success, failure, chagrin, joy, humiliation, pleasure, distress and delight. They are whole children responding in a total way, and what they feel is a constant factor that can be constructive or destructive in any learning situation.”
—Dorothy H. Cohen (20th century)
“Ask anyone committed to Marxist analysis how many angels on the head of a pin, and you will be asked in return to never mind the angels, tell me who controls the production of pins.”
—Joan Didion (b. 1934)
“The real pleasure of being Mick Jagger was in having everything but being tempted by nothing ... a smouldering ill will which silk clothes, fine food, wine, women, and every conceivable physical pampering somehow aggravated ... a drained and languorous, exquisitely photogenic ennui.”
—Anonymous “Chronicler.” Quoted in Philip Norman, The Life and Good Times of the Rolling Stones (1989)
“Criticism is a study by which men grow important and formidable at very small expense. The power of invention has been conferred by nature upon few, and the labour of learning those sciences which may, by mere labour, be obtained, is too great to be willingly endured; but every man can exert some judgment as he has upon the works of others; and he whom nature has made weak, and idleness keeps ignorant, may yet support his vanity by the name of critic.”
—Samuel Johnson (1709–1784)
