QUES: In quantum mechanics and quantum field theory, the vacuum is defined as the state (that is, the solution to the equations of the theory) with the lowest possible energy (the ground state of the Hilbert space). In quantum electrodynamics this vacuum is referred to as 'QED vacuum' to distinguish it from the vacuum of quantum chromodynamics, denoted as QCD vacuum. QED vacuum is a state with no matter particles (hence the name), and also no photons. As described above, this state is impossible to achieve experimentally. (Even if every matter particle could somehow be removed from a volume, it would be impossible to eliminate all the blackbody photons.) Nonetheless, it provides a good model for realizable vacuum, and agrees with a number of experimental observations as described next.
What is a blackbody photon referred to in quantum mechanics?

ANS: unanswerable

QUES: The Golden Boot is awarded to the top Premier League scorer at the end of each season. Former Blackburn Rovers and Newcastle United striker Alan Shearer holds the record for most Premier League goals with 260. Twenty-four players have reached the 100-goal mark. Since the first Premier League season in 199293, 14 different players from 10 different clubs have won or shared the top scorers title. Thierry Henry won his fourth overall scoring title by scoring 27 goals in the 200506 season. Andrew Cole and Alan Shearer hold the record for most goals in a season (34) for Newcastle and Blackburn respectively. Ryan Giggs of Manchester United holds the record for scoring goals in consecutive seasons, having scored in the first 21 seasons of the league.
How many players have 100 goals or more in the Premier League?

ANS: Twenty-four

QUES: The number of species of flowering plants is estimated to be in the range of 250,000 to 400,000. This compares to around 12,000 species of moss or 11,000 species of pteridophytes, showing that the flowering plants are much more diverse. The number of families in APG (1998) was 462. In APG II (2003) it is not settled; at maximum it is 457, but within this number there are 55 optional segregates, so that the minimum number of families in this system is 402. In APG III (2009) there are 415 families.
How many species of moss is there?

ANS: 12,000

QUES: Adjacent to the palace is the Royal Mews, also designed by Nash, where the royal carriages, including the Gold State Coach, are housed. This rococo gilt coach, designed by Sir William Chambers in 1760, has painted panels by G. B. Cipriani. It was first used for the State Opening of Parliament by George III in 1762 and has been used by the monarch for every coronation since George IV. It was last used for the Golden Jubilee of Elizabeth II. Also housed in the mews are the coach horses used at royal ceremonial processions.
Who knows nothing about the Gold State Coach?
