Since the 1995 proof of Fermat’s Last Theorem, a problem which stood for 365 years, the current longest-standing maths problem is the conjecture posed by Christian Goldbach (1690-1764), a Russian mathematician, in 1742. Goldbach’s Conjecture states that every even positive integer greater than 3 is the sum of two (not necessarily distinct) primes. No one has succeeded in proving or disproving the validity of this conjecture in 257 years. Mathematicians worldwide hold the Riemann Hypothesis of 1859 (posed by German mathematician Bernhard Riemann (1826-1866)) as

Marco Ferrera (USA) achieved a whistle measuring 125 dB at 2.5 m (8 ft 3 in) away in the Deadroom at Schtung Music Studios, Santa Monica, Califormia, USA on 5 March 2004. The level is comparable to an air raid siren!
The Chrysler air raid sirens are the loudest sirens ever constructed, capable of producing 138 decibels at a distance of 100 ft (30 m). The sirens are so loud that a normal person would be deafened within 60 m (200 ft) of one during operation. The sirens were introduced as the official warning siren for US cities in 1952. Powered Hemi engines, they are able to discharge 74 m³ (2,610 ft³) of air per second, and are powerful enough to cause a piece of paper
