  2. Modern valence bond theory - Wikipedia

    en.wikipedia.org/wiki/Modern_valence_bond_theory

    This wavefunction describes the bonding in H 2 as the ionic interaction between an H + and an H-. Since none of these wavefunctions, Φ HL (covalent bonding) or Φ I (ionic bonding) perfectly approximates the wavefunction, a combination of these two can be used to describe the total wavefunction

    For example, in the case of the F 2 molecule, the F−F bond is formed by the overlap of p z orbitals of the two F atoms, each containing an unpaired electron. Since the nature of the overlapping orbitals are different in H 2 and F 2 molecules, the bond strength and bond lengths differ between H 2 and F 2 molecules.

  4. Modula-3 - Wikipedia

    en.wikipedia.org/wiki/Modula-3

    Modula-3 is a programming language conceived as a successor to an upgraded version of Modula-2 known as Modula-2+. It has been influential in research circles (influencing the designs of languages such as Java , C# , Python [ 8 ] and Nim ), but it has not been adopted widely in industry.

    The SI unit of molar attenuation coefficient is the square metre per mole (m 2 /mol), but in practice, quantities are usually expressed in terms of M −1 ⋅cm −1 or L⋅mol −1 ⋅cm −1 (the latter two units are both equal to 0.1 m 2 /mol). In older literature, the cm 2 /mol is sometimes used; 1 M −1 ⋅cm −1 equals 1000 cm 2 /mol.

  6. Modelica - Wikipedia

    en.wikipedia.org/wiki/Modelica

    Modelica 1.0 is based on the PhD thesis [5] of Hilding Elmqvist and on the experience with the modeling languages Allan, [6] Dymola, NMF [7] ObjectMath, [8] Omola, [9] SIDOPS+, [10] and Smile. [11] Hilding Elmqvist is the key architect of Modelica, but many other people have contributed as well (see appendix E in the Modelica specification [ 2 ] ).

  7. It is known as the "Wizard Book" in hacker culture. [1] It teaches fundamental principles of computer programming, including recursion, abstraction, modularity, and programming language design and implementation. MIT Press published the first edition in 1984, and the second edition in 1996.

  9. Outline of computer programming - Wikipedia

    en.wikipedia.org/.../Outline_of_computer_programming

    Programming involves activities such as analysis, developing understanding, generating algorithms, verification of requirements of algorithms including their correctness and resources consumption, and implementation (commonly referred to as coding [1] [2]) of algorithms in a target programming language.
