Human being is a living random number generator

General wisdom is, mathematical operation is needed to generate number by numbers. It is pointed out that without any mathematical operation true random numbers can be generated by numbers through algorithmic process. It implies that human brain itself is a living true random number generator. Human brain can meet the enormous human demand of true random numbers. Number as well as a string of non/pseudo-random numbers can be generated by numbers with the help of mathematical operation through algorithmic process [1,2]. Although there is no mathematical proof that random numbers cannot be generated by any classical algorithm, but it is widely believed that random numbers can be generated only by using random events. It may be recalled that von Neumann first ruled out [1] the possibility of generating random numbers by any mathematical operation. There is a caveat. von Neumann did not rule out the generation of random numbers by any algorithmic technique. In fact, it is possible to generate random numbers by using simple quantum algorithm [3] which exploits intrinsic randomness of quantum system. From the above discussion it may be conjectured that if any classical algorithm does not require mathematical operation to generate numbers, then it can be a good candidate for the generation of both random and non-random numbers. We have found such algorithm. Let us first present the most simple one.
