Context and question: Regularity is a concept based on adherence to Masonic Landmarks, the basic membership requirements, tenets and rituals of the craft. Each Grand Lodge sets its own definition of what these landmarks are, and thus what is Regular and what is Irregular (and the definitions do not necessarily agree between Grand Lodges). Essentially, every Grand Lodge will hold that its landmarks (its requirements, tenets and rituals) are Regular, and judge other Grand Lodges based on those. If the differences are significant, one Grand Lodge may declare the other "Irregular" and withdraw or withhold recognition.
What are never considered "Irregular"?
Answer: unanswerable
Context and question: One example of omnidirectional antennas is the very common vertical antenna or whip antenna consisting of a metal rod (often, but not always, a quarter of a wavelength long). A dipole antenna is similar but consists of two such conductors extending in opposite directions, with a total length that is often, but not always, a half of a wavelength long. Dipoles are typically oriented horizontally in which case they are weakly directional: signals are reasonably well radiated toward or received from all directions with the exception of the direction along the conductor itself; this region is called the antenna blind cone or null.
In which direction would you expect to find a dipole?
Answer: horizontally
Context and question: The British Library notes that "Chopin's works have been recorded by all the great pianists of the recording era." The earliest recording was an 1895 performance by Paul Pabst of the Nocturne in E major Op. 62 No. 2. The British Library site makes available a number of historic recordings, including some by Alfred Cortot, Ignaz Friedman, Vladimir Horowitz, Benno Moiseiwitsch, Paderewski, Arthur Rubinstein, Xaver Scharwenka and many others. A select discography of recordings of Chopin works by pianists representing the various pedagogic traditions stemming from Chopin is given by Methuen-Campbell in his work tracing the lineage and character of those traditions.
Who has given a discography of pianists' representation of Chopin's pedagogic style?
Answer:
Methuen-Campbell
