SMS Baden was one of four Sachsen-class armored frigates of the GermanImperial Navy. Built in the Imperial Dockyard in Kiel from 1876 to 1883 and armed with a main battery of six 26 cm (10 in) guns in two open barbettes, she was commissioned in September 1883. Baden served on numerous training exercises and cruises in the 1880s and 1890s and participated in several cruises escorting Kaiser Wilhelm II on state visits. During 1896–1897, the ship was extensively rebuilt. She was removed from active duty in 1910, served in a number of secondary roles, and was sold in April 1938 and broken up in 1939–1940.Illustration: Hugo Graf; restoration: Adam Cuerden
Daedongyeojido is a large scale map of Korea produced by Chosun Dynasty cartographer and geologist Kim Jeong-ho in 1861. Considered to mark the zenith of pre-modern Korean cartography, the map consists of 22 separate, foldable booklets, each covering approximately 47 kilometres (29 mi) (north-south) by 31.5 kilometres (19.6 mi) (east-west). Combined, they form a map of Korea that is 6.7 metres (22 ft) wide and 3.8 metres (12 ft) long. Daedongyeojido is praised for precise delineations of mountain ridges, waterways, and transportation routes, as well as its markings for settlements, administrative areas, and cultural sites.Map: Kim Jeong-ho

A side-by-side comparison of the Aral Sea in 1989 and 2008, showing its severe shrinkage owing to poor water resource management. The Aral Sea was once the fourth-largest lake in the world. However, the rivers that fed it were diverted by Soviet-era irrigation projects. It had shrunk to 10% of its former size by 2007, and is still shrinking. The near-loss of the Aral Sea, which is now in Kazakhstan and Uzbekistan, has been considered one of the planet's most disastrous examples of poor environmental resource management.Photographs: NASA; edit: Zafiroblue05
A gas mask (Polish MUA model pictured) is a mask used to protect the user from inhaling airborne pollutants and toxic gases. It forms a sealed cover over the wearer's nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Most gas masks are also respirators, though the term gas mask is often used to refer to military equipment (e.g. a field protective mask). Gas masks do not protect from gas that the skin can absorb.Photograph: Nikodem Nijaki

Sam Poo Kong is the oldest Chinese temple in Semarang, Central Java, Indonesia. The complex was first used by the Chinese Muslim explorer Zheng He. Though Zheng's temple collapsed in a 1704 landslide, a new one was built in its place. This temple has seen several restorations, most recently from 2002 to 2005. Sam Poo Kong is now shared by Indonesians of multiple religious denominations, including Muslims and Buddhists, and ethnicities.

A map of the Battle of Jutland, a naval battle fought by the British Royal Navy's Grand Fleet against the Imperial German Navy's High Seas Fleet during the First World War. The only full-scale clash of battleships in the war, the Germans intended it to lure out, trap and destroy a portion of the Grand Fleet, as the German naval force was insufficient to openly engage the entire British fleet. Fourteen British and eleven German ships were sunk, and more than 8,000 people were killed. Both sides claimed victory, and dispute over the significance of the battle continues to this day.Map: Grandiose
