    The player experiences some time in Perry's life. The plan appears to have had positive effects. Based on this simulation, the plan is deemed viable and preparations are set in motion. However, Perelman feels that the ten-year simulation isn't enough, and makes PRISM do a simulation of the situation 20 years after the plan started, and then 30 ...

    Lens clock. A lens clock is a mechanical dial indicator that is used to measure the dioptric power of a lens.It is a specialized version of a spherometer.A lens clock measures the curvature of a surface, but gives the result as an optical power in diopters, assuming the lens is made of a material with a particular refractive index.

  7. Wedge prism - Wikipedia

    en.wikipedia.org/wiki/Wedge_prism

    Wedge prism. The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from ...

  8. Threefold model - Wikipedia

    en.wikipedia.org/wiki/Threefold_model

    v. t. e. The threefold model or GDS theory of roleplaying games is an attempt to distinguish three different goals in roleplaying. In its original formation, these are: Drama, simulation, and game. It was the inspiration for subsequent theories, such as the GNS theory, which retained a three-way division but altered other aspects of the model.
