Are LCGs truly random?
No, Linear Congruential Generators (LCGs) are not truly random; they are pseudorandom number generators (PRNGs) that produce sequences which appear random but are actually deterministic, repeating patterns based on a mathematical formula and an initial seed value, making them predictable if the constants and seed are known. While great for speed and simplicity in many simulations, their predictability and potential for uneven distribution mean they're unsuitable for high-security or high-quality randomness needs like cryptography, where better PRNGs (like Mersenne Twister) or true hardware RNGs are used.Is rand() actually random?
If you look up C++ documentation on rand() , you'll see that it returns "a pseudo-random integral value between 0 and RAND_MAX ." Click again on RAND_MAX and you'll see that "This value is implementation dependent.How do LCGs work?
An LCG (Linear Congruential Generator) works by using a simple formula, Xn+1=(aXn+c)modmcap X sub n plus 1 end-sub equals open paren a cap X sub n plus c close paren mod m𝑋𝑛+1=(𝑎𝑋𝑛+𝑐)mod𝑚, to generate a sequence of numbers that look random but are actually predictable, starting from a 'seed' value and repeating based on chosen constants (multiplier aa𝑎, increment cc𝑐, modulus mm𝑚). It's fast and easy to code, making it great for basic simulations, but its patterns mean it's not truly random and has limitations, though careful parameter selection (like using large primes) can extend its cycle length significantly.Why is 37 so random?
Round numbers like 10 or 50 feel too obvious, primes like 37 feel less predictable, and the number itself carries no strong cultural associations—so it simply feels random.

Currently, many systems rely on pseudorandom processes such as thermal noise or chaotic oscillation, which exhibit some unpredictability, but are still fundamentally deterministic.Is Anything Truly Random?
Do tachyons actually exist?
No, tachyons are hypothetical particles that travel faster than light and have never been observed, though they remain a fascinating concept in physics, often appearing as mathematical solutions indicating an unstable system rather than actual FTL particles. While they challenge Einstein's relativity and could break causality (allowing time travel), modern physics treats them as signals of an unstable field (like the Higgs field's early state) that decays into stable particles with real mass, rather than real FTL entities.Did Einstein believe in randomness?
Einstein believed in “perfect laws in the world of things existing as real objects” and not “in God playing dice.” He affirmed that what appeared to be randomness was in reality human ignorance of hidden variables.Is 1000000000000066600000000000001 a prime number?
Due to the superstitious significance of the numbers it contains, the palindromic prime 1000000000000066600000000000001 is known as Belphegor's Prime, named after Belphegor, one of the seven princes of Hell.Is 12345678910987654321 prime?
The number 12,345,678,910,987,654,321 is indeed prime. It consists of 20 digits and is really easy to remember: count to 10 and then count backward again until you get to 1. But it has been unclear whether other primes take the palindromic form of starting at 1, ascending to the number n and then descending again.Who decided 1 wasn't prime?
Caldwell and Xiong start with classical Greek mathematicians. They did not consider 1 to be a number in the same way that 2, 3, 4, and so on are numbers. 1 was considered a unit, and a number was composed of multiple units. For that reason, 1 couldn't have been prime — it wasn't even a number.What are the disadvantages of using an LCG?
Despite their widespread usage, it is important to recognize that LCGs have limitations. They are sensitive to the choice of parameters and if not configured properly can produce sequences with poor statistical properties such as short periods (how quickly they repeat themselves) or predictable patterns.What is an LCG vs TCG?
In TCGs, card packs are randomized, meaning players never know exactly what they'll get. LCGs, however, provide fixed card sets, so players know what they are getting with each purchase. This makes LCGs a better choice for those who prefer a more predictable gaming experience.Are LCGs suitable for Monte Carlo simulations?
Monte Carlo simulation requires a pseudo-random number generator with good statistical properties. Linear congruential generators (LCGs) are the most popular and well-studied computer method for generating pseudo-random numbers used in Monte Carlo studies.Does God allow randomness?
To summarize, the Bible tells us that the randomness we see in the world about us is not without purpose and is within the plan and directives of God. The randomness we see can be reconciled with the doctrine of divine providence. This harmony is difficult to understand, but we should accept the biblical assurance.Are RNGs truly random?
Random number generators are typically software, pseudo random number generators. Their outputs are not truly random numbers. Instead they rely on algorithms to mimic the selection of a value to approximate true randomness.Are lottery numbers actually random?
The balls are random so there is a very slim chance that a number will repeat–in the neighborhood of 3 or 4%. But, don't forget: You have the same chance that any other ball is chosen, too.Why is 37 so special?
The number 37 is special due to its unique mathematical properties as a prime, being an emirp (reverses to another prime, 73), a safe prime (2*17+1), and appearing in sequences like Cuban primes, while also fitting into human decision-making patterns, often appearing when people try to pick a "random" number. It symbolizes wisdom in some spiritual contexts and is linked to Christ in early Christian traditions, making it significant in both secular and mystical ways.Is 2099 prime?
Yes, 2099 is a prime number, meaning it's only divisible by 1 and itself, with no other whole number factors, making it a unique number often noted in number theory curiosities.What is 1 ➗ 0 and why?
1 divided by 0 (1/0) is undefined in standard arithmetic because there's no number that, when multiplied by 0, equals 1, as anything times 0 is always 0, creating a mathematical contradiction, though in some advanced contexts (like calculus limits or floating-point math standards), it can relate to infinity or be handled as an error.Is 170141183460469231731687303715884105727 prime number?
Using this algorithm with hand computations on paper, Lucas showed in 1876 that the 39-digit number (2127 – 1) equals 170,141,183,460,469,231,731,687,303,715,884,105,727, and that value is prime. Also known as M127, this number remains the largest prime verified by hand computations.What is the cursed prime number?
Belphegor's prime is the palindromic prime number 1000000000000066600000000000001 (1030 + 666 × 1014 + 1), a number which reads the same both backwards and forwards and is only divisible by itself and one.Why is 95% of the universe invisible?
Surprisingly, normal matter turns out to be only a small fraction of what the Universe contains. 95% of the Universe is made up of dark matter and dark energy.Does quantum physics believe in God?
Skeptics will argue that quantum physics doesn't prove spirituality is real, or God exists. But this argument is built on the assumption that science is the only model able to validify the existence of God, or spiritual dimensions. Quantum physics in itself doesn't prove anything.Has e-mc2 been disproved?
GAITHERSBURG--Albert Einstein was correct in his prediction that E=mc2, according to scientists at the Massachusetts Institute of Technology (MIT), the Commerce Department's National Institute of Standards and Technology (NIST), and the Institute Laue Langevin, Genoble, France (ILL) who conducted the most precise ...
