In the Low Middle Ages, Catalan went through a golden age, reaching a peak of maturity and cultural richness. Examples include the work of Majorcan polymath Ramon Llull (1232–1315), the Four Great Chronicles (13th–14th centuries), and the Valencian school of poetry culminating in Ausiàs March (1397–1459). By the 15th century, the city of Valencia had become the sociocultural center of the Crown of Aragon, and Catalan was present all over the Mediterranean world. During this period, the Royal Chancery propagated a highly standardized language. Catalan was widely used as an official language in Sicily until the 15th century, and in Sardinia until the 17th. During this period, the language was what Costa Carreras terms "one of the 'great languages' of medieval Europe".
Until what century was Catalan used as the official language in Sardinia?

In June 2009, many of the world's largest mobile phone manufacturers signed an EC-sponsored Memorandum of Understanding (MoU), agreeing to make most data-enabled mobile phones marketed in the European Union compatible with a common External Power Supply (EPS). The EU's common EPS specification (EN 62684:2010) references the USB Battery Charging standard and is similar to the GSMA/OMTP and Chinese charging solutions. In January 2011, the International Electrotechnical Commission (IEC) released its version of the (EU's) common EPS standard as IEC 62684:2011.
When did the IEC release its version of the common EPS standard as IEC 62684:2011?
January 2011

The Hellenistic age also saw a rise in the disillusionment with traditional religion. The rise of philosophy and the sciences had removed the gods from many of their traditional domains such as their role in the movement of the heavenly bodies and natural disasters. The Sophists proclaimed the centrality of humanity and agnosticism; the belief in Euhemerism (the view that the gods were simply ancient kings and heroes), became popular. The popular philosopher Epicurus promoted a view of disinterested gods living far away from the human realm in metakosmia. The apotheosis of rulers also brought the idea of divinity down to earth. While there does seem to have been a substantial decline in religiosity, this was mostly reserved for the educated classes.
Who thought that gods were distant and uninterested?
Epicurus
