WebThe U-Pb system is a prime geochronometer, mainly due to its occurrence as a pair of isotopically distinct but chemically identical decay systems with U-235 decaying to Pb-207 and U-238 to Pb-206, respectively. In addition, U has suitable half-lives and is hosted in some very convenient minerals, such as the widespread and robust mineral zircon. A twin prime is a prime number that is either 2 less or 2 more than another prime number—for example, either member of the twin prime pair (41, 43). In other words, a twin prime is a prime that has a prime gap of two. Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is … See more Usually the pair (2, 3) is not considered to be a pair of twin primes. Since 2 is the only even prime, this pair is the only pair of prime numbers that differ by one; thus twin primes are as closely spaced as possible for any … See more In 1940, Paul Erdős showed that there is a constant c < 1 and infinitely many primes p such that p′ − p < c ln p where p′ denotes the next prime after p. What this means is that we can find … See more Beginning in 2007, two distributed computing projects, Twin Prime Search and PrimeGrid, have produced several record-largest twin primes. As of August 2024 , the current largest … See more An isolated prime (also known as single prime or non-twin prime) is a prime number p such that neither p − 2 nor p + 2 is prime. In other words, p is not part of a twin prime pair. For example, 23 is an isolated prime, since 21 and 25 are both composite See more The question of whether there exist infinitely many twin primes has been one of the great open questions in number theory for many years. This is the content of the twin prime conjecture, which states that there are infinitely many primes p such that p + 2 is … See more First Hardy–Littlewood conjecture The Hardy–Littlewood conjecture (named after G. H. Hardy and John Littlewood) is a generalization of the … See more Every third odd number is divisible by 3, which requires that no three successive odd numbers can be prime unless one of them is 3. Five is therefore the only prime that is part of two twin prime pairs. The lower member of a pair is by definition a Chen prime See more
