Symbol
- In graph theory, the connectivity of a graph is given by κ.
- In differential geometry, the curvature of a curve is given by κ.
- In physics, the torsional constant of an oscillator is given by κ as well as Einstein constant of gravitation.
- In structural engineering, κ is the ratio of the smaller factored moment to the larger factored moment and is used to calculate the critical elastic moment of an unbraced steel member.
- In electrical engineering, κ is the multiplication factor, a function of the R/X ratio of the equivalent power system network, which is used in calculating the peak short-circuit current of a system fault. κ is also used to notate conductivity, the reciprocal of resistivity, rho.
- In chemistry, the compressibility of a compound is given by κ.
- In psychology and psychiatry, kappa represents a measure of diagnostic reliability.
- In biology, kappa and kappa prime are important nucleotide motifs for a tertiary interaction of group II introns.
- In biology, kappa designates a subtype of an antibody component.
- In pharmacology, kappa represents a type of opioid receptor.
- Kappa statistics such as Cohen's kappa and Fleiss' kappa are methods for calculating inter-rater reliability.
Upper-case letter Κ is used as a symbol for:
- In textual criticism, the Byzantine text-type (from Κοινη, Koine, the common text).
- In set theory, kappa is often used to denote an ordinal which is also a cardinal.

Famous quotes containing the word symbol:
“The truth has never been of any real value to any human being—it is a symbol for mathematicians and philosophers to pursue. In human relations kindness and lies are worth a thousand truths.”
—Graham Greene (1904–1991)
“There is that in me—I do not know what it is—but I know it is in me ...
I do not know it—it is without name—it is a word unsaid,
It is not in any dictionary, utterance, symbol ...
Do you see O my brothers and sisters?
It is not chaos or death—it is form, union, plan—it is eternal life—it is Happiness.”
—Walt Whitman (1819–1892)
“In a symbol there is concealment and yet revelation: here therefore, by silence and by speech acting together, comes a double significance.... In the symbol proper, what we can call a symbol, there is ever, more or less distinctly and directly, some embodiment and revelation of the Infinite; the Infinite is made to blend itself with the Finite, to stand visible, and as it were, attainable there. By symbols, accordingly, is man guided and commanded, made happy, made wretched.”
—Thomas Carlyle (1795–1881)
