Direct and indirect band gaps. In semiconductor physics, the band gap of a semiconductor can be of two basic types, a direct band gap or an indirect band gap. The minimal-energy state in the conduction band and the maximal-energy state in the valence band are each characterized by a certain crystal momentum (k-vector) in the Brillouin zone.
Indirect speech. In linguistics, speech or indirect discourse is a grammatical mechanism for reporting the content of another utterance without directly quoting it. For example, the English sentence Jill said she was coming is indirect discourse while Jill said "I'm coming" would be direct discourse. In fiction, the "utterance" might amount to ...

One may, for instance, say, "Peter, can you close the window?", thereby asking Peter whether he will be able to close the window, but also requesting that he ...
Direct effect in a mediation model. In the diagram shown above, the indirect effect is the product of path coefficients "A" and "B". The direct effect is the coefficient " C' ". The direct effect measures the extent to which the dependent variable changes when the independent variable increases by one unit and the mediator variable remains ...

This was particularly used by colonial empires like the British Empire to control their possessions in Africa and Asia, which was done through pre-existing indigenous power structures.

Evidentiality may be direct or indirect: direct evidentials are used to describe information directly perceived by the speaker through vision as well as other sensory experiences while indirect evidentials consist of the other grammatical markers for evidence such as quotatives and inferentials.
Direct realism, also known as naïve realism, argues we perceive the world directly. In the philosophy of perception and philosophy of mind, direct or naïve realism, as opposed to indirect or representational realism, are differing models that describe the nature of conscious experiences; [1] [2] out of the metaphysical question of whether the world we see around us is the real world itself ...
Indirect approach. The Indirect approach is a military strategy described and chronicled by B. H. Liddell Hart after World War I. It was an attempt to find a solution to the problem of high casualty rates in conflict zones with high force to space ratios, such as the Western Front on which he served. The strategy calls for armies to advance ...
