Question: The Vedas, the earliest texts on Indian philosophy and Hindu philosophy dating back to the late 2nd millennium BC, describe ancient Hindu cosmology, in which the universe goes through repeated cycles of creation, destruction and rebirth, with each cycle lasting 4,320 million years. Ancient Greek philosophers, including Parmenides and Heraclitus, wrote essays on the nature of time. Plato, in the Timaeus, identified time with the period of motion of the heavenly bodies. Aristotle, in Book IV of his Physica defined time as 'number of movement in respect of the before and after'.
Is there an answer to this question: How long ago are the earliest texts of Heraclitus philosophy dated?

Answer: unanswerable

Question: In the Byzantine Rite of the Eastern Orthodox Church and the Eastern Catholic Churches, the music performed in the liturgies is exclusively sung without instrumental accompaniment. Bishop Kallistos Ware says, "The service is sung, even though there may be no choir... In the Orthodox Church today, as in the early Church, singing is unaccompanied and instrumental music is not found." This a cappella behavior arises from strict interpretation of Psalms 150, which states, Let every thing that hath breath praise the Lord. Praise ye the Lord. In keeping with this philosophy, early Russian musika which started appearing in the late 17th century, in what was known as khoroviye kontserti (choral concertos) made a cappella adaptations of Venetian-styled pieces, such as the treatise, Grammatika musikiyskaya (1675), by Nikolai Diletsky. Divine Liturgies and Western Rite masses composed by famous composers such as Peter Tchaikovsky, Sergei Rachmaninoff, Alexander Arkhangelsky, and Mykola Leontovych are fine examples of this.
Is there an answer to this question: When did Russian musika show up?

Answer: khoroviye kontserti

Question: Unlike the papabile cardinals Giacomo Lercaro of Bologna and Giuseppe Siri of Genoa, he was not identified with either the left or right, nor was he seen as a radical reformer. He was viewed as most likely to continue the Second Vatican Council, which already, without any tangible results, had lasted longer than anticipated by John XXIII, who had a vision but "did not have a clear agenda. His rhetoric seems to have had a note of over-optimism, a confidence in progress, which was characteristic of the 1960s." When John XXIII died of stomach cancer on 3 June 1963, it triggered a conclave to elect a new pope.
Is there an answer to this question: What role did Pope John XXIII's death precipitate the election of?

Answer: pope

Question: Near-infrared is the region closest in wavelength to the radiation detectable by the human eye, mid- and far-infrared are progressively further from the visible spectrum. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (the common silicon detectors are sensitive to about 1,050 nm, while InGaAs's sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately, international standards for these specifications are not currently available.
Is there an answer to this question: What InGaAs is progressively further from the visible spectrum for the human eye?

Answer:
unanswerable
