  2. Schrödinger equation - Wikipedia

    en.wikipedia.org/wiki/Schrödinger_equation

    Solving the equation by separation of variables means seeking a solution of the form of a product of spatial and temporal parts [18] (,) = (), where () is a function of all the spatial coordinate(s) of the particle(s) constituting the system only, and () is a function of time only.

  3. Mathematics - Wikipedia

    Mathematics is essential in the natural sciences, engineering, medicine, finance, computer science, and the social sciences. Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent of any scientific experimentation.

  4. John von Neumann - Wikipedia

    en.wikipedia.org/wiki/John_von_Neumann

    The positive solution for spaces of dimension at most two, and the negative solution for higher dimensions, comes from the fact that the Euclidean group is a solvable group for dimension at most two, and is not solvable for higher dimensions. "Thus, according to von Neumann, it is the change of group that makes a difference, not the change of ...

    en.wikipedia.org/wiki/General_relativity

    In global geometry, the object of study is not one particular solution (or family of solutions) to Einstein's equations. Rather, relations that hold true for all geodesics, such as the Raychaudhuri equation , and additional non-specific assumptions about the nature of matter (usually in the form of energy conditions ) are used to derive general ...

    en.wikipedia.org/wiki/COBOL

    A PICTURE (or PIC) clause is a string of characters, each of which represents a portion of the data item and what it may contain. Some picture characters specify the type of the item and how many characters or digits it occupies in memory. For example, a 9 indicates a decimal digit, and an S indicates that the item is signed.

    His solution held the record as the fastest version for over 30 years, and its successor is faster by only 2%. [29] His solution was formalized and published in collaboration with Harvard computer scientist Christos Papadimitriou. [30] Gates remained in contact with Paul Allen and joined him at Honeywell during the summer of 1974. [31]
