What is a Random Number Generator?
A random number generator (RNG) is a computational or physical process designed to generate a sequence of numbers or symbols that lack any pattern and follow no specific order. The goal is to produce numbers that are statistically random, meaning that each number is independent of the others and has an equal chance of being chosen.
There are two main types of random number generators:
- Pseudorandom Number Generators (PRNG): These generators use algorithms to produce sequences of numbers that approximate true randomness. The sequences they generate are deterministic, meaning that if you know the starting point (seed), you can reproduce the entire sequence. PRNGs are widely used in computer programming and simulations.
- True Random Number Generators (TRNG): These generators derive randomness from physical processes or sources that are inherently unpredictable. Examples include atmospheric noise, radioactive decay, electronic noise, or other quantum phenomena. TRNGs are often used in situations where higher levels of unpredictability and security are required.
Is there “true” Randomness?
“True” randomness has been a scientific puzzle that delves into the understanding of reality and the question of determinism. In classical Physics, nature is deterministic where everything can be predicted as long as you know the initial conditions an object or phenomena had.
However, quantum mechanics, a fundamental theory in physics that describes the behavior of particles on very small scales, introduces an element of inherent uncertainty. According to the principles of quantum mechanics, certain processes, such as the decay of a radioactive atom or the measurement of a particle’s spin, appear to be inherently probabilistic and not strictly deterministic.
True randomness, in this context, refers to events or processes that are fundamentally unpredictable, even in principle. Quantum mechanics suggests that at the most fundamental level, some aspects of the universe are intrinsically random. For example, the outcome of a quantum measurement is often described using probabilities, and it is not possible to predict the exact result.
