How random is "Randomness"?

" I am the byproduct of randomness in the universe."

How do you define randomness? which phenomenon in the universe is called random and which is deterministic? Does randomness have some order or sequence? If there is order in everything then why is it called random? These questions are not simple to answer as there are so many random answer to these questions. As such if we look vaguely or even surfacely the universe itself is random, each and every incident that occurs in the universe is random. There is probability and matter of chance, the outcome can be as expected but these are random events. Birth is a random event and so is the death. A baby who is going to be born can be a boy or girl, can weight 2 kg or 3 kg, can have long nose or flat, can have small eyes or large, nobody knows exactly unless he is in the universe. So there is randomness mixed with expectation from each individual. Some believe he or she should be so and so. However, there is always a better prediction based on the known knowledge about the parents, locality and the surrounding, dieting behavior and so on. Once he or she is in the universe, the randomness about life begins. Noone knows what a child is feeling and noone lnows how long a child is going to live further. There is only guess and expectation from different people, but nobody is sure about it. So for us every other being in the universe is a random event, so are we random for them. Not only other beings, we are random in ourselves, we are random in our thinking and we are random in our behavior. I do not know what am I going to think in 5 minutes and I do not know how am I going to respond a random question that may be asked to me at some point in time. I can just predict, what I may say but I am not sure about it. The incident is random. 

This is how we are surrounded by randomness in every instant. As such some of the events that are believed to be deterministic are also random, we can predict statistically what may happen but we do not know exactly what is going to happen. We know it is going to be sunny in summer from our experiences and statistical knowledge from the past experiences but we can't exactly say how strong is the sun and how long the sun lasts for sure. These events are totally random events of the universe. Though each and every event is random, we believe that everything goes as expected and expectation comes from the previous knowledge of these random events. We can predict how an event is going to take place, we can predict the result and consequences, we can predict the behavior in the next time instant and all these predictions come from the knowledge of the behavior of the event, knowledge of the impact of the surrounding and the knowledge of the past experiences of the event.

These things have motivated me to write some random feelings about randomness. How random is randomness? This question has not only been a matter of curiosity to philosophers, but also to the mathematicians, researchers, engineers and scientists. The main challenge to the mathematicians is if something is random, then how to represent them in numbers. There can be infinite possible representation of random behavior. These possibilities gave birth to the idea called notion of degrees of randomness or how strong (random) is a random event and what is the past behavior of the random event. So statistically mathematicians look for the distribution of random events maybe over time or space or other parameters of change. Scientists, researchers and engineers are predicting and expecting the behavior (output) of an invention based on the number of random results obtained at different instant of time or space or other parameters of change. To the philosophers, the randomness is more interesting because the life is dull without randomness. If everything is deterministic in life, then we predict everything 50 years ago and there is no charm of living, there is no joy and no expectation of being on the universe.

Since everything is random, now we can argue how random is an event? How random are we within ourselves? How random are our parents or friends or siblings with respect to us? How random is our surrounding? We can predict somehow each of them depending upon the degree of randomness and their previous behavior. Statistically speaking, if we know the distribution of the past behavior of each of the events, we can determine the expected randomness and behavior from each of them, which is again not a deterministic event. So this question should keep a prime importance in prediction of an event “ how to prioritize randomness?” Determine how random is an event and weight them accordingly. This gives a feeling that randomness can be relative, and an event with a very very low weighted randomness can be called a deterministic event and the one with very very high weighted randomness as a highly random event.

Randomness in itself is a random phenomenon which can be statistically studied and measured with some degrees of randomness to apply to predict the outcome of an event; and the issue of randomness is always interesting for researchers as it is always going to be random.
