In Greece, copper was known by the name chalkos (). It was an important resource for the Romans, Greeks and other ancient peoples. In Roman times, it was known as aes Cyprium, aes being the generic Latin term for copper alloys and Cyprium from Cyprus, where much copper was mined. The phrase was simplified to cuprum, hence the English copper. Aphrodite and Venus represented copper in mythology and alchemy, because of its lustrous beauty, its ancient use in producing mirrors, and its association with Cyprus, which was sacred to the goddess. The seven heavenly bodies known to the ancients were associated with the seven metals known in antiquity, and Venus was assigned to copper.

Windows 8 introduces a new style of application, Windows Store apps. According to Microsoft developer Jensen Harris, these apps are to be optimized for touchscreen environments and are more specialized than current desktop applications. Apps can run either in a full-screen mode, or be snapped to the side of a screen. Apps can provide toast notifications on screen or animate their tiles on the Start screen with dynamic content. Apps can use "contracts"; a collection of hooks to provide common functionality that can integrate with other apps, including search and sharing. Apps can also provide integration with other services; for example, the People app can connect to a variety of different social networks and services (such as Facebook, Skype, and People service), while the Photos app can aggregate photos from services such as Facebook and Flickr.
What makes Windows Store apps unique?

In the medieval Middle Eastern world, the physicist and Islamic scholar, Al-Farabi (Alpharabius, 872950), conducted a small experiment concerning the existence of vacuum, in which he investigated handheld plungers in water.[unreliable source?] He concluded that air's volume can expand to fill available space, and he suggested that the concept of perfect vacuum was incoherent. However, according to Nader El-Bizri, the physicist Ibn al-Haytham (Alhazen, 9651039) and the Mu'tazili theologians disagreed with Aristotle and Al-Farabi, and they supported the existence of a void. Using geometry, Ibn al-Haytham mathematically demonstrated that place (al-makan) is the imagined three-dimensional void between the inner surfaces of a containing body. According to Ahmad Dallal, Abu Rayhan al-Biruni also states that "there is no observable evidence that rules out the possibility of vacuum". The suction pump later appeared in Europe from the 15th century.
Al-Farabi concluded a perfect vacuum was incoherent using what?
****
The answer: handheld plungers in water.

By April 1945, China had already been at war with Japan for more than seven years. Both nations were exhausted by years of battles, bombings and blockades. After Japanese victories in Operation Ichi-Go, Japan were losing the battle in Burma and facing constant attacks from Chinese Nationalists forces and Communist guerrillas in the country side. The Japanese army began preparations for the Battle of West Hunan in March 1945. Japanese mobilized 34th, 47th, 64th, 68th and 116th Divisions, as well as the 86th Independent Brigade, for a total of 80,000 men to seize Chinese airfields and secure railroads in West Hunan by early April. In response, the Chinese National Military Council dispatched the 4th Front Army and the 10th and 27th Army Groups with He Yingqin as commander-in-chief. At the same time, it airlifted the entire Chinese New 6th Corps, an American-equipped corps and veterans of the Burma Expeditionary Force, from Kunming to Zhijiang. Chinese forces totaled 110,000 men in 20 divisions. They were supported by about 400 aircraft from Chinese and American air forces. Chinese forces achieved a decisive victory and launched a large counterattack in this campaign. Concurrently, the Chinese managed to repel a Japanese offensive in Henan and Hubei. Afterwards, Chinese forces retook Hunan and Hubei provinces in South China. Chinese launched a counter offensive to retake Guangxi which was the last major Japanese stronghold in South China. In August 1945, Chinese forces successfully retook Guangxi.[citation needed]
