Problem: British Isles:

The Greco-Egyptian scientist Claudius Ptolemy referred to the larger island as great Britain (μεγάλης Βρεττανίας - megális Brettanias) and to Ireland as little Britain (μικρής Βρεττανίας - mikris Brettanias) in his work Almagest (147–148 AD). In his later work, Geography (c. 150 AD), he gave these islands the names Alwion, Iwernia, and Mona (the Isle of Man), suggesting these may have been names of the individual islands not known to him at the time of writing Almagest. The name Albion appears to have fallen out of use sometime after the Roman conquest of Great Britain, after which Britain became the more commonplace name for the island called Great Britain.

In what year did the British scientist Claudius Ptolemy complete his work, Geography?

Problem: Current circulating in one antenna generally induces a voltage across the feedpoint of nearby antennas or antenna elements. The mathematics presented below are useful in analyzing the electrical behaviour of antenna arrays, where the properties of the individual array elements (such as half wave dipoles) are already known. If those elements were widely separated and driven in a certain amplitude and phase, then each would act independently as that element is known to. However, because of the mutual interaction between their electric and magnetic fields due to proximity, the currents in each element are not simply a function of the applied voltage (according to its driving point impedance), but depend on the currents in the other nearby elements. Note that this now is a near field phenomenon which could not be properly accounted for using the Friis transmission equation for instance.
What induces a feedpoint to antennas nearby?

Answer: Current circulating

Context and question: The emergence of Vedanta school represented a period when a more knowledge-centered understanding began to emerge. These focussed on jnana (knowledge) driven aspects of the Vedic religion and the Upanishads. This included metaphysical concepts such as ātman and Brahman, and emphasized meditation, self-discipline, self-knowledge and abstract spirituality, rather than ritualism. The Upanishads were variously interpreted by ancient and medieval era Vedanta scholars. Consequently, the Vedanta separated into many sub-schools, ranging from theistic dualism to non-theistic monism, each interpreting the texts in its own way and producing its own series of sub-commentaries.
On what aspects of Vedic did the Vedanta understanding focus?
Answer: jnana


Question: International tribunals and arbiters are often called upon to resolve substantial disputes over treaty interpretations. To establish the meaning in context, these judicial bodies may review the preparatory work from the negotiation and drafting of the treaty as well as the final, signed treaty itself.
Is there an answer to this question: What judicial bodies might be called upon to resolve disputes pertaining to the interpretation of treaties?

Answer: International tribunals and arbiters


QUES: In 2006, after almost 80 years, NBC Universal sold all Walt Disney-produced Oswald cartoons, along with the rights to the character himself, back to Disney. In return, Disney released ABC sportscaster Al Michaels from his contract so he could work on NBC's Sunday night NFL football package. However, Universal retained ownership of Oswald cartoons produced for them by Walter Lantz from 1929 to 1943.

What did Universal retain ownership of from 1923 to 1949?
