Lightbulb Geomorphology


Quote:
The Minoan eruption of Thera, also referred to as the Thera eruption or Santorini eruption, was a major catastrophic volcanic eruption with a Volcanic Explosivity Index (VEI) of 6 or 7 and a dense-rock equivalent (DRE) of 60 km3 (14 cu mi), which is estimated to have occurred in the mid second millennium BCE.. The eruption was one of the largest volcanic events on Earth in recorded history.. The eruption devastated the island of Thera (also called Santorini), including the Minoan settlement at Akrotiri, as well as communities and agricultural areas on nearby islands and on the coast of Crete..There are no clear ancient records of the eruption; the eruption seems to have inspired certain Greek myths, may have caused turmoil in Egypt, and may be alluded to in a Chinese chronicle. Additionally, it has been speculated that the Minoan eruption and the destruction of the city at Akrotiri provided the basis for or otherwise inspired Plato's story of Atlantis.. Some theories of the biblical Exodus use the eruption to explain its accounts of plagues and disasters in Egypt around this time...

Soc. To be sure I will: the chief theme of my yesterday's discourse was the State-how constituted and of what citizens composed it would seem likely to be most perfect..

Tim. Yes, Socrates; and what you said of it was very much to our mind.

Soc. Did we not begin by separating the husbandmen and the artisans from the class of defenders of the State?

Tim. Yes.

Soc. And when we had given to each one that single employment and particular art which was suited to his nature, we spoke of those who were intended to be our warriors, and said that they were to be guardians of the city against attacks from within as well as from without, and to have no other employment; they were to be merciful in judging their subjects, of whom they were by nature friends, but fierce to their enemies, when they came across them in battle.

Tim. Exactly.

Soc. We said, if I am not mistaken, that the guardians should be gifted with a temperament in a high degree both passionate and philosophical; and that then they would be as they ought to be, gentle to their friends and fierce with their enemies.

Tim. Certainly.

Soc. And what did we say of their education? Were they not to be trained in gymnastic, and music, and all other sorts of knowledge which were proper for them?

Tim. Very true.

Soc. And being thus trained they were not to consider gold or silver or anything else to be their own private property; they were to be like hired troops, receiving pay for keeping guard from those who were protected by them-the pay was to be no more than would suffice for men of simple life; and they were to spend in common, and to live together in the continual practice of virtue, which was to be their sole pursuit.

Tim. That was also said.

Soc. Neither did we forget the women; of whom we declared, that their natures should be assimilated and brought into harmony with those of the men, and that common pursuits should be assigned to them both in time of war and in their ordinary life.

Tim. That, again, was as you say.

Soc. And what about the procreation of children? Or rather not the proposal too singular to be forgotten? for all wives and children were to be in common, to the intent that no one should ever know his own child, but they were to imagine that they were all one family; those who were within a suitable limit of age were to be brothers and sisters, those who were of an elder generation parents and grandparents, and those of a younger children and grandchildren.

Tim. Yes, and the proposal is easy to remember, as you say.

Soc. And do you also remember how, with a view of securing as far as we could the best breed, we said that the chief magistrates, male and female, should contrive secretly, by the use of certain lots, so to arrange the nuptial meeting, that the bad of either sex and the good of either sex might pair with their like; and there was to be no quarrelling on this account, for they would imagine that the union was a mere accident, and was to be attributed to the lot?

Tim. I remember.

Soc. And you remember how we said that the children of the good parents were to be educated, and the children of the bad secretly dispersed among the inferior citizens; and while they were all growing up the rulers were to be on the look-out, and to bring up from below in their turn those who were worthy, and those among themselves who were unworthy were to take the places of those who came up?

Tim. True.

Soc. Then have I now given you all the heads of our yesterday's discussion? Or is there anything more, my dear Timaeus, which has been omitted?

Tim. Nothing, Socrates; it was just as you have said...

Geomorphology (from Greek: γῆ, ge, "earth"; μορφή, morfĂ©, "form"; and λόγος, logos, "study") is the scientific study of landforms and the processes that shape them. Geomorphologists seek to understand why landscapes look the way they do, to understand landform history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphology is practiced within physical geography, geology, geodesy, engineering geology, archaeology and geotechnical engineering. This broad base of interest contributes to many research styles and interests within the field..The surface of Earth is modified by a combination of surface processes that sculpt landscapes, and geologic processes that cause tectonic uplift and subsidence.. Surface processes comprise the action of water, wind, ice, fire, and living things on the surface of the Earth, along with chemical reactions that form soils and alter material properties, the stability and rate of change of topography under the force of gravity, and other factors, such as (in the very recent past) human alteration of the landscape..The first theory of geomorphology was arguably devised by the polymath Chinese scientist and statesman Shen Kuo (1031-1095 AD).. This was based on his observation of marine fossil shells in a geological stratum of a mountain hundreds of miles from the Pacific Ocean..Santorini has two ports: Athinios (Ferry Port) and Skala (Old Port).. Cruise ships anchor off Skala and passengers are transferred by local boatmen to shore at Skala where Fira is accessed by cable car, on foot or by donkey.. Tour boats depart from Skala for Nea Kameni And other destinations...

That was before experience taught me that life was tragical enough without my having to write about it..What if courage and imagination became everyday mortal qualities...http://www.davidicke.com/forum/showp...postcount=1750
