  2. Newton's rings - Wikipedia

    en.wikipedia.org/wiki/Newton's_rings

    The light passes through the glass lens until it comes to the glass-to-air boundary, where the transmitted light goes from a higher refractive index (n) value to a lower n value. The transmitted light passes through this boundary with no phase change. The reflected light undergoing internal reflection (about 4% of the total) also has no phase ...

    Śrīdhara wrote two extant mathematical treatises. The first, Pāṭīgaṇita, also called Bṛhat-Pāṭi ("Bigger Pāṭi") and Navaśatī ("Having 900"), extensively covered the practical mathematics of the time including arithmetic and mensuration (the part of geometry concerned with calculating sizes, lengths, areas, and volumes).

    Remains NP-complete for 3-sets. Solvable in polynomial time for 2-sets (this is a matching). [2] [3]: SP2 Finding the global minimum solution of a Hartree-Fock problem [37] Upward planarity testing [8] Hospitals-and-residents problem with couples; Knot genus [38]

  6. Mathematical analysis - Wikipedia

    en.wikipedia.org/wiki/Mathematical_analysis

    Numerical analysis is the study of algorithms that use numerical approximation (as opposed to general symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics). [25] Modern numerical analysis does not seek exact answers, because exact answers are often impossible to obtain in practice.
