Nomadism

Roofs are a basic element of shelter from inclement weather. Natural or hewn caves, including those of snow or ice, ate early evidence of human endeavors for protection from the cold, wind, rain, and sun. Nomadic people, before the benefits of agriculture had been discovered and housing schemes developed, depended on the availabiUty of natural materials to constmct shelters. Portable shelters, eg, tents, probably appeared early in history. Later, more permanent stmctures were developed from stone and brick. SaUent features depended strongly on the avadabihty of natural materials. The Babylonians used mud to form bricks and tiles that could be bonded with mortars or natural bitumen. Ancient buildings in Egypt were characterized by massive walls of stone and closely spaced columns that carried stone lintels to support a flat roof, often made of stone slabs. 

One of the reasons the tribes of early history were nomadic was to move periodically away from the stench of the animal, vegetable, and human wastes they generated. When the tribesmen learned to use fire, they used it for millennia in a way that filled the air inside their living quarters with the products of incomplete combustion. Examples of this can still be seen today in some of fhe more primitive parts of the world. After its invention, the chimney removed the combustion products and cooking smells from the living quarters, but for centuries the open fire in the fireplace caused its emission to be smoky. In ad 61 the Roman philosopher Seneca reported thus on conditions in Rome ... 

Anthropological research with modern hunter-gatherers suggests an ideal type or model for this kind of society. They were nomadic and exhibited low population size and density—on the order of thirty people per thousand square miles. Paramount in maiiitaining this low size and density was an imperative common to all hunter-gatherer women. A nomad woman had to move herself, all that her family owned (which was very little), and her children at a moments notice. Modern hunters and gatherers often have to walk twenty miles a day, so mothers cannot carry more than one small child. Faced with this restriction, women are careful to space their children so that the two or rarely three children they have...

Desert environments also pose different ambient conditions than that normally encountered at most oil and gas facilities. The most obvious is that the ambient temperature level can reach extremely high levels, as much as 54.4 °C (130 °F) and that sand storms can be expected to occur. Typical problems of free range roving livestock (camels, sheep, goats, etc.) with their nomadic herders may also exist. 

I merely remarked, returned the younger priest, smiling, that you must see a great many of these nomadic individuals in this quaint little town of yours. I have been here but a week and that is the sixth villainous looking rascal who has presented himself and demanded something to eat. ... 

Most lists of emotions exclude the esthetic emotions, Pugh (1977) being an exception. Yet how can one otherwise account for the universality of art and music (see also Dissayanake, 1988 Eibl-Eibesfeldt, 1989) Various animals seem to have a preference for certain geographical features such a tendency would be adaptive in guiding nomadic species to appropriate habitats, just as humans everywhere seem to perfer savannah-like terrain for their parks. The appeal of ideal features of babies or mates might also be included under this emotion, but perhaps placed elsewhere.

We do such things using mind. And what is mind We haven t a clue. Twenty-thousand years from nomadic hunting and gathering to cybernetics and spaceflight. And we are still accelerating. There are yet more waves to come. From the Model-T Ford to the starship one hundred years. From the fastest man on earth being able to move thirty miles per hour to nine miles per second sixty years.
