With Elizabeth's accession, it seemed probable that the royal house would bear her husband's name, becoming the House of Mountbatten, in line with the custom of a wife taking her husband's surname on marriage. The British Prime Minister, Winston Churchill, and Elizabeth's grandmother, Queen Mary, favoured the retention of the House of Windsor, and so on 9 April 1952 Elizabeth issued a declaration that Windsor would continue to be the name of the royal house. The Duke complained, "I am the only man in the country not allowed to give his name to his own children." In 1960, after the death of Queen Mary in 1953 and the resignation of Churchill in 1955, the surname Mountbatten-Windsor was adopted for Philip and Elizabeth's male-line descendants who do not carry royal titles.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many male-line descendants do Elizabeth and Philip have with no royal title?
Ah, so.. unanswerable

In February 2016, it was confirmed by BBC Worldwide that Keeping Up Appearances is the corporation's most exported television programme, being sold nearly 1000 times to overseas broadcasters.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): As of early 2016, what BBC show has been sold outside of the country the most times?
Ah, so.. Keeping Up Appearances

In the past, small batches of amorphous metals with high surface area configurations (ribbons, wires, films, etc.) have been produced through the implementation of extremely rapid rates of cooling. This was initially termed "splat cooling" by doctoral student W. Klement at Caltech, who showed that cooling rates on the order of millions of degrees per second is sufficient to impede the formation of crystals, and the metallic atoms become "locked into" a glassy state. Amorphous metal wires have been produced by sputtering molten metal onto a spinning metal disk. More recently a number of alloys have been produced in layers with thickness exceeding 1 millimeter. These are known as bulk metallic glasses (BMG). Liquidmetal Technologies sell a number of zirconium-based BMGs. Batches of amorphous steel have also been produced that demonstrate mechanical properties far exceeding those found in conventional steel alloys.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of metal makes better alloys than traditional steel?
Ah, so..
amorphous steel
