SMS Grosser Kurfürst was the second battleship of the four-ship König class of the German Imperial Navy. Her name refers to Frederick William, Elector of Brandenburg. Launched on 5 May 1913, she served during World War I. She was armed with ten 30.5-centimeter (12.0 in) guns in five twin turrets. Along with her three sister ships, König, Markgraf, and Kronprinz, Grosser Kurfürst took part in most of the fleet actions during the war, including the Battle of Jutland on 31 May and 1 June 1916. The ship was subjected to heavy fire at Jutland, but was not seriously damaged. She shelled Russian positions during Operation Albion in September and October 1917. In her service career, she collided with König and Kronprinz, grounded several times, was torpedoed once, and hit a mine. After the war, Grosser Kurfürst and most of the capital ships of the High Seas Fleet were interned by the Royal Navy in Scapa Flow, and later scuttled by their German crews. (Full article...)

Sutton Hoo Helmet is a 2002 sculpture by the English artist Rick Kirby. A representation of the Anglo-Saxon helmet of the same name found in the Sutton Hoo ship-burial, it was commissioned by the National Trust to hang outside the Sutton Hoo visitor centre. Together with the centre, the sculpture was unveiled by Nobel laureate Seamus Heaney on 13 March 2002. Weighing 900 kg (2,000 lb), it is 1.8 m (5.9 ft) high, 1.2 m (3.9 ft) wide and 1.6 m (5.2 ft) deep. It is made of mild steel plates that are coloured red. Designed to have a "fierce presence", it is inspired by the fragmentary appearance of the reconstructed helmet rather than the glistening replica made by the Royal Armouries. Steel is Kirby's favoured medium, allowing the sense of scale and dramatic impact found in Sutton Hoo Helmet. The sculpture is illustrative of Kirby's largely figural body of work, and its mask-like quality has been repeated in subsequent pieces. (Full article...)

Fourteen singles topped the Billboard Hot 100 in 2011. The Billboard Hot 100 is a chart that ranks the best-performing singles of the United States. Its data, published by Billboard magazine and compiled by Nielsen SoundScan, was based collectively on each single's weekly physical and digital sales, as well as airplay. In 2011, nine acts achieved their first US number-one single, either as a lead artist or a featured guest. Six collaboration singles topped the chart. Pop singers Adele, Britney Spears, Katy Perry and Rihanna (pictured) each earned two number-one songs during the year. One of Adele's songs, "Rolling in the Deep", was the best-performing single of 2011, topping the Billboard Year-End Hot 100. She became the fourth solo female to have multiple songs spend at least five weeks each at number one in one calendar year. Rihanna's "We Found Love" was the longest-running single of the year, having topped the chart for eight consecutive weeks in 2011 and two additional weeks in 2012. (Full list...)
