Randomness is a lack of predictability. And the word” predictability “in knowledgeable people is accompanied by an additional word — “reliability” or, more cool, the level of reliability of the prediction.�

You might say, ” What are you talking about? If I let go of this glass of wine, it will fall to the floor and break, and the wine will spill out on the floor, and this is a 100% forecast. There is no randomness in this example!”. But it's not that simple. It is possible that during the fall of the glass you will find yourself in the epicenter of a nuclear explosion and you and the glass will evaporate. This probability is very small, but not zero, especially since now there are three nutters at the helm of three nuclear states. Something else may happen. A gas explosion (terrorist attack) in the next room (from below, from above, from the sides) and your experiment will not end as you predicted. The probability of this is higher than that of a nuclear explosion, and is easily calculated by the known frequency of gas explosions in homes. There are other options for making an error in your forecast. Think about it — you will find it (or your colleagues will add it in the comments).

Mrs. Randomness is involved everywhere and in everything. The contribution of randomness is huge in the quantum world (microcosm) and never zero in the universe. After all, the universe is a child of Chance. What we call the Big Bang is the fluctuation of the scalar field (although no one knows what it is) and the subsequent fluctuations of the generated vacuum (space-time with curvature). A fluctuation is the realization of a random process (for example, a number) from a set of possible processes (numbers), according to a certain law (the distribution function of these numbers).

Einstein believed that it is possible to predict the time of decay of a radioactive element, and this is not possible, only because of the presence of certain hidden parameters in the description (in the wave function) of the state of the element. In this he was wrong and it is proved. It is impossible to predict the moment of decay of a radioactive element due to the randomness of quantum processes. But this randomness strictly obeys the corresponding distribution function (exponential, in the case of decay), which follows from quantum mechanics and coincides strictly with the statistical results of experiments.

This is our Universe. Randomness is everywhere. As the great Murphy used to say, “You can't tell which side of a sandwich to butter in advance.”

Chance is the shadow of the goal. When we map out a scenario of the future in our head, then randomness appears as a deviation from it. For example, if you were driving to a village and hit an elk on the way, then this meeting will probably be an accident, but if you had the task of knocking down an elk, then your arrival in the village will be an accident.

This term helps people significantly simplify their vision of what is happening, creating the illusion of the existence of predictable, regular and controlled events.

In my opinion, there are no accidents in the world, in the universe. Everything is natural, everything is interconnected, everything is responsive. Randomness has no meaning, no order. Even Voltaire said: “There are no accidents — everything in this world is either a test, or a punishment, or a reward, or a harbinger.”

Randomness is an unexplained pattern. There are many reasons for this. First of all, because of the subjectivity of perception and different points of view, and, as a result, the different possibility and availability of information to which everyone has their own attitude.
If you cross an empty road and even at a green traffic light, and a car jumps out of the corner and hits you, this is not an accident, but an unforeseen event due to insufficient information from the pedestrian and driver.

Randomness can be considered a certain event, which can not be found the reasons. However, there are reasons for any phenomenon, action, event, but they may not be available to the observer, for example, due to insufficient possession of consciousness, i.e. the inability to penetrate the essence of the phenomenon and determine its cause (root). Therefore, “randomness” is a judgment based on obvious signs.

6. edward_wolanski says:

Randomness is an unknown pattern. Naturally, there are exceptions to this Law. But they, like all others in any industry, do not affect the manifestation of the Law.

Randomness undoubtedly exists, but only in the human mind. The more developed the consciousness, the less chance there is for a person in his life.

If you acquire the art of observation, you will feel that many of your events are preceded by giving you certain signs. Rather, not for your personality, but for the situation.

If we look closely, for example, at the history of physics, we will clearly see that what was an accident yesterday has now become a pattern

This is the dialectical process of cognition.

7. timofey_bondarenko says:

Randomness is an uncontrolled and unreadable pattern. We can only calculate and predict some “average”, but we can't accurately predict the result. Figuratively speaking, randomness is something whose causes and regularities lie beyond the horizon of our knowledge.

But in practice, sometimes even where it is possible to predict more accurately, this accuracy may be too expensive, and it is easier to use a probabilistic description.
