Problem: Zinc:

The Charaka Samhita, thought to have been written between 300 and 500 AD, mentions a metal which, when oxidized, produces pushpanjan, thought to be zinc oxide. Zinc mines at Zawar, near Udaipur in India, have been active since the Mauryan period. The smelting of metallic zinc here, however, appears to have begun around the 12th century AD. One estimate is that this location produced an estimated million tonnes of metallic zinc and zinc oxide from the 12th to 16th centuries. Another estimate gives a total production of 60,000 tonnes of metallic zinc over this period. The Rasaratna Samuccaya, written in approximately the 13th century AD, mentions two types of zinc-containing ores: one used for metal extraction and another used for medicinal purposes.

When was the Rasaratna Samuccaya destroyed?

Problem: Turner Classic Movies:

In 1986, eight years before the launch of Turner Classic Movies, Ted Turner acquired the Metro-Goldwyn-Mayer film studio for $1.5 billion. Concerns over Turner Entertainment's corporate debt load resulted in Turner selling the studio that October back to Kirk Kerkorian, from whom Turner had purchased the studio less than a year before. As part of the deal, Turner Entertainment retained ownership of MGM's library of films released up to May 9, 1986. Turner Broadcasting System was split into two companies; Turner Broadcasting System and Metro-Goldwyn-Mayer and reincorporated as MGM/UA Communications Co.

Up to what date of release did Kerkorian retain ownership of the MGM film library?

Problem: Film speed:

The ASA standard underwent a major revision in 1960 with ASA PH2.5-1960, when the method to determine film speed was refined and previously applied safety factors against under-exposure were abandoned, effectively doubling the nominal speed of many black-and-white negative films. For example, an Ilford HP3 that had been rated at 200 ASA before 1960 was labeled 400 ASA afterwards without any change to the emulsion. Similar changes were applied to the DIN system with DIN 4512:1961-10 and the BS system with BS 1380:1963 in the following years.

When were changes applied to the DIN system?
