Model-toy
In Physical, a model-toy is a simplified representation of a mathematical model or Physique. It can be to use to more easily include/understand a mechanism or a not-popularized theory.
-
a mathematical model-toy is often carried out by reducing the number of Dimension S, by reducing the number of Variable S or field S, or by limiting them to a particular symmetrical form.
- a physical model-toy is characterized for a daily example or a similar mechanism which is often used to illustrate an effect with an aim of making it easier to visualize.
Some examples of physical model-toys can be: orbital mechanics described by two whirling spheres attached by an elastic ; the radiation of Hawking around a Black hole describes by a conventional radiation of a fictitious membrane whose ray is worth r=2M; …
