  2. Prentice position - Wikipedia

    en.wikipedia.org/wiki/Prentice_position

    The Prentice position is an orientation of a prism, used in optics, optometry and ophthalmology. [1] In this position, named after the optician Charles F. Prentice, the prism is oriented such that light enters it at an angle of 90° to the first surface, so that the beam does not refract at that surface. All the deviation caused by the prism ...

  3. Šidák correction for t-test - Wikipedia

    en.wikipedia.org/wiki/Šidák_correction_for_t-test

    One of the application of Student's t-test is to test the location of one sequence of independent and identically distributed random variables.If we want to test the locations of multiple sequences of such variables, Šidák correction should be applied in order to calibrate the level of the Student's t-test.

  4. Free-air gravity anomaly - Wikipedia

    en.wikipedia.org/wiki/Free-air_gravity_anomaly

    The free-air correction adjusts measurements of gravity to what would have been measured at mean sea level, that is, on the geoid. The gravitational attraction of Earth below the measurement point and above mean sea level is ignored and it is imagined that the observed gravity is measured in air, hence the name.

    Young and Restless is the fourth studio album by Canadian rock band Prism, released in May 1980 by Capitol Records.The album is notably the band's last studio album to feature lead vocalist Ron Tabak, and it is also the last album to feature their long-time producer, Bruce Fairbairn.

    Figure 1. View through 10 factor wedge prism of an "IN" tree. Figure 2. View through 10 factor wedge prism of a "Borderline" tree. Figure 3. View through 10 factor wedge prism of an "OUT" tree. The wedge prism is primarily used in a similar manner as an angle gauge in variable-radius plot sampling.

  7. Bouguer anomaly - Wikipedia

    en.wikipedia.org/wiki/Bouguer_anomaly

    is the free-air gravity anomaly. is the Bouguer correction which allows for the gravitational attraction of rocks between the measurement point and sea level; is a terrain correction which allows for deviations of the surface from an infinite horizontal plane

  8. Triangular prism - Wikipedia

    en.wikipedia.org/wiki/Triangular_prism

    In geometry, a triangular prism or trigonal prism [1] is a prism with 2 triangular bases. If the edges pair with each triangle's vertex and if they are perpendicular to the base, it is a right triangular prism. A right triangular prism may be both semiregular and uniform. The triangular prism can be used in constructing another polyhedron.

  9. Madhava's correction term - Wikipedia

    en.wikipedia.org/wiki/Madhava's_correction_term

    Madhava's correction term is a mathematical expression attributed to Madhava of Sangamagrama (c. 1340 – c. 1425), the founder of the Kerala school of astronomy and mathematics, that can be used to give a better approximation to the value of the mathematical constant π (pi) than the partial sum approximation obtained by truncating the Madhava–Leibniz infinite series for π.
