Definitions for randomness
This page provides all possible meanings and translations of the word randomness
randomness, entropy, S(noun)
(thermodynamics) a thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work
"entropy increases as matter and energy in the universe degrade to an ultimate state of inert uniformity"
randomness, haphazardness, stochasticity, noise(noun)
the quality of lacking any predictable order or plan
The property of all possible outcomes being equally likely.
A type of circumstance or event that is described by a probability distribution.
A measure of the lack of purpose, logic or objectivity of an event.
There was no randomness in the teacher's selection of the class representative.
Randomness means different things in various fields. Commonly, it means lack of pattern or predictability in events. The Oxford English Dictionary defines "random" as "Having no definite aim or purpose; not sent or guided in a particular direction; made, done, occurring, etc., without method or conscious choice; haphazard." This concept of randomness suggests a non-order or non-coherence in a sequence of symbols or steps, such that there is no intelligible pattern or combination. Applied usage in science, mathematics and statistics recognizes a lack of predictability when referring to randomness, but admits regularities in the occurrences of events whose outcomes are not certain. For example, when throwing two dice and counting the total, we can say that a sum of 7 will randomly occur twice as often as 4. This view, where randomness simply refers to situations where the certainty of the outcome is at issue, applies to concepts of chance, probability, and information entropy. In these situations, randomness implies a measure of uncertainty, and notions of haphazardness are irrelevant. The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. A random process is a sequence of random variables describing a process whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions. These and other constructs are extremely useful in probability theory.
The New Hacker's Dictionary
1. An inexplicable misfeature; gratuitous inelegance. 2. A hack or crock that depends on a complex combination of coincidences (or, possibly, the combination upon which the crock depends for its accidental failure to malfunction). “This hack can output characters 40--57 by putting the character in the four-bit accumulator field of an XCT and then extracting six bits — the low 2 bits of the XCT opcode are the right thing.” “What randomness!” 3. Of people, synonymous with flakiness. The connotation is that the person so described is behaving weirdly, incompetently, or inappropriately for reasons which are (a) too tiresome to bother inquiring into, (b) are probably as inscrutable as quantum phenomena anyway, and (c) are likely to pass with time. “Maybe he has a real complaint, or maybe it's just randomness. See if he calls back.”Despite the negative connotations of most jargon uses of this term have, it is worth noting that randomness can actually be a valuable resource, very useful for applications in cryptography and elsewhere. Computers are so thoroughly deterministic that they have a hard time generating high-quality randomness, so hackers have sometimes felt the need to built special-purpose contraptions for this purpose alone. One well-known website offers random bits generated by radioactive decay. Another derives random bits from chaotic systems in analog electronics. Originally, the latter site got its random bits by doing photometry on lava lamps. Hackers invariably found this hilarious. If you have to ask why, you'll never get it.)
Sample Sentences & Example Usage
Enemies of the all powerful God, guess what folks? The universe doesn't know or care. If you appreciate the miracle of creation is randomness and that's what makes creation a miracle-congratulations. You've made it into the God club.
There have been quite a number of St. Louis County cases where we see African-American men sentenced to death by all-white juries, and it's just not the kind of thing that can be explained by randomness or chance, there's just been a repeated pattern.
Schrodinger's Cat is a classic example of Paradox, in my view. In actuality, it was a Gedankenexperiment or a Thought Experiment, created by Austrian Physicist Erwin Schrodinger in 1935. Not many folks are probably aware that Schrodinger himself called that experiment “a ridiculous case.” Here’s the "Schrodinger's Cat" in Schrodinger's own words: “A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): In a Geiger Counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none. If it (i.e. decay) happens, the Geiger Counter discharges and through a relay releases a hammer that shatters a small flask of Hydrogen Cyanide. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has (undergone) radioactive decay.” So you see, the cat's life or death truly depends on the formation of a subatomic alpha particle that triggers off the avalanche of electrons in the Geiger Counter. There is an equal probability that it may not happen, and hence the cat should remain both alive and dead per Copenhagen interpretation of quantum mechanics. Philosophically speaking, Human Life is full of paradoxes, and we often find that the uncertainties therein bear a startling resemblance with Schrodinger's Cat experiment. The total randomness of events that shape our human lives, and determinedly control the outcome (i.e. future) can be extremely perplexing and equally thought-provoking as Schrodinger's Cat experiment....a pre-written and pre-destined Reductio ad absurdum perhaps!
