Wreck of the RMS Titanic intact and undamaged dresser behind it. Robert Ballard has suggested that areas within the ship or buried under debris, where scavengers may not have been able to reach, may still contain human remains. According to Charles Pellegrino, who dived on "Titanic" in 2001, a finger bone encircled by the partial remains of a wedding ring was found concreted to the bottom of a soup tureen that was retrieved from the debris field. It was returned to the sea bed on the next dive. The longest-lasting inhabitants of "Titanic" are likely to be bacteria and archaea which have colonized the metal
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
