The Modern Role of the PC

It is made up of senior politicians who are current or former members of the House of Lords or House of Commons, to the Sovereign of the United Kingdom.

The PC is made up of various Committees and is presided over by a Lord President. The JCPC, or Judicial Committee of the Privy Council, is one such committee.

The Witenagemot

What is "rectification", why is it so useful, and what does a rectifier have to do with it?

A rectifier is a piece of electronic kit that converts A.C. to D.C. This process is known as rectification.

Rectifiers are often found as components of D.C. power supplies (many electronic circuits require a steady D.C. current e.g. radio, television and computer equipment).

The opposite process, of converting D.C. to A.C., requires more complex circuitry in the form of an inverter. Different types of inverters produce different "quality" waves ranging from square waveforms, sine waves to modified sine waves.

Mr Holmes (2015)

Mr Holmes is a 2015 film in which an aged Sherlock Holmes is dealing with dementia. It is based on a book called "A Slight Trick of the Mind" (published 2005) by Santa Fe-born novelist and short story writer Mitch Cullin.

Ian McKellen (English Literature graduate from St Catherine's College Cambridge, where he was a member of the Marlowe Society, a theatre club for Cambridge students, who has famously played Gandalf in Lord of the Rings, and made his professional debut in 1961 at the Belgrade Theatre, Coventry in Robert Bolt's A Man for All Seasons) plays Sherlock with NYC-born and Julliard alum Laura Linney playing Mrs Munro. Ipswich, England-born Milo Parker plays Roger. Lambeth-born Hattie Morahan (who graduated from New Hall, Cambridge with a BA in English) plays Ann Kelmot who the mystery revolves around. Her husband is played by Patrick Kennedy.

Hiroyuki Sanada plays Umezaki with whom Sherlock Holmes meets in Japan and has an ensuing correspondence relationship.

Bees are an interesting symbol in the story, forming a bond between Sherlock and Roger, as well as Sherlock and Umezaki, via an amber fossil which Umezaki gifts Sherlock, which he passes on to Roger, and finally lays out in the final scene on the White Cliffs of Dover.

The film grossed $29m at the box office over an estimated budget of $10m.
