Sinking of the RMS Titanic cultural phenomenon, commemorated by artists, film-makers, writers, composers, musicians and dancers from the time immediately after the sinking to the present day. On 1 September 1985, a joint US-French expedition led by Robert Ballard found the wreck of "Titanic", and the ship's rediscovery led to an explosion of interest in "Titanic"s story. Numerous expeditions have been launched to film the wreck and, controversially, to salvage objects from the debris field. The first major exhibition of recovered artefacts was held at London's National Maritime Museum in 1994–95. In 1997, James Cameron's eponymous film became the first movie ever to take $1
Titanic prime the prime number theorem. The first discovered titanic primes were the Mersenne primes 2−1 (with 1281 digits), and 2−1 (with 1332 digits). They were both found November 3, 1961, by Alexander Hurwitz. It is a matter of definition which one was discovered first, since the primality of 2−1 was computed first, but Hurwitz saw the computer output about 2−1 first. Samuel Yates called those who proved the primality of a titanic prime "titans". Titanic prime Titanic prime is a term coined by Samuel Yates in the 1980s, denoting a prime number of at least 1000 decimal digits. Few such primes
