Poets and society

Perhaps no other occupation demands so much thought for so little output, epitomized in the Japanese haiku tradition, which involves production of seventeen syllable poems. Even in other traditions including thousand-line poems, a poet's total lifetime output might fill only two or three volumes. For this reason, poets occupy a peculiar position in society, even when compared to other artists, tending to reside on the fringes of their culture. Even poets who have achieved prominence within their tradition can remain completely unknown in the world at large.

Because of this typically low cultural status, the practice of poetry itself is oftentimes a hobby or side activity rather than the central focus on an individual's life. In the past, bards of remarkable skill might be maintained by a lord or by royalty as part of the artistic coterie at court. Away from the refinement of court, wandering troubadours would have brought their romantic, bawdy chansons from town to town, supporting themselves by passing the hat.

Volcano

A volcano is a geological landform usually generated by the eruption through a vent in a planet's surface of magma, molten rock welling up from the planet's interior. Volcanoes of various types are found on other planets and their moons as well as on earth. Roughly defined, a volcano consists of a magma chamber, pipes and vents. The magma chamber is where magma from deep within the planet pools, while pipes are channels that lead to surface vents, openings in the volcano's surface through which lava is ejected during an eruption.

Though the common perception of a volcano as mountain spewing lava and poisonous gases from a crater in its top is not wrong per se, the features of volcanoes are much more complicated and vary from volcano to volcano depending on a number of factors. Some volcanoes even have rugged peaks formed by lava domes rather than a summit crater, whereas others present landscape features such as massive plateaus. Vents that issue volcanic material and gases can be located anywhere on the landform.

Vedas

The Vedas are among the most antique books in the world, and they are the foundation texts of Hinduism. Veda means knowledge. Any form of Knowledge acquired is considered as a Veda whereby it has no beginning or end. While it might surprise people how a book can have no creation or end, the ancient Rishis who wrote these established that the complete knowledge of the Universe could never fit in any book, and so there would always be new things to discover. This philosophy makes Hinduism a very understanding religion, always ready to accept new ideas from other cultures.

The Vedas were compiled by the great sage Krishna Dwipayana during the Dwapara Yuga with the goal to come up with a de-facto standard of education. Upon gathering all the knowledge passed on from the Acharyas to their Sishyas from Kingdom to Kingdom, he compiled them into 4 standard structures; the Rigveda, Yajurveda, Samaveda and Atharvaveda. Upon completion of this great feat he was given the title "Veda Vyasa" which means "Compiler of the Vedas".

Rhythm

Rhythm is the difference of the accentuation of sounds or other events over time. "Rhythm involves patterns of duration that are phenomenally present in the music" with duration perceived by interonset interval. When governed by rule, it is called meter. It is intrinsic in any time-dependent medium, but it is most related with music, dance, and the majority of poetry. The study of rhythm, stress, and pitch in speech is called prosody; it is a topic in linguistics. All musicians, instrumentalists and vocalists, work with rhythm, but it is often considered the primary domain of drummers and percussionists.

In Western music, rhythms are usually arranged with respect to a time signature, partially signifying a meter. The speed of the underlying pulse, called the beat, is the tempo. The tempo is frequently measured in 'beats per minute’; 60 bpm means a speed of one beat per second. The length of the meter, or metric unit, is regularly grouped into either two or three beats, being called duple meter and triple meter, respectively. If each beat is grouped in two, it is simple meter, if in three compound meter.

Tsunami

A tsunami is a series of waves generated when a body of water, such as an ocean is rapidly displaced on a massive scale. Earthquakes, mass movements above or below water, volcanic eruptions and large meteorite impacts all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable to devastating.

The term tsunami comes from the Japanese language meaning harbour and wave. Although in Japanese tsunami is used for both the singular and plural, in English tsunamis is well-set as the plural. The term was created by fishermen who returned to port to find the area surrounding their harbour devastated, although they had not been aware of any wave in the open water. A tsunami is not a sub-surface event in the deep ocean; it simply has much smaller amplitude offshore, and a very long wavelength, which is why they generally pass, unnoticed at sea, forming only a passing "hump" in the ocean.
