A random process is a recurring process of an indefinite factor, but it also follows a probability distribution. This term is often used in statistics to express some well-defined, thorough statistical properties, such as missing deviations or correlations. Random and arbitrary, because “one variable is random” means that this variable follows the rules of the probability distribution. However, it implies that the variable does not follow the distributive law in another aspect. So randomness has an important position in natural science and philosophy. This work takes advantage of the randomness of metal to intrigue deep thinking. As metals of the same quality are presented in a different state after melting and solidification.
