Design of experiments

The experiments conducted in accord with the scientific method have several features in common. The design of experiments attempts to balance the requirements and limitations of the field of science in which one works so that the experiment can provide the best conclusion about the hypothesis being tested.

In some sciences, such as physics and chemistry, it is relatively easy to meet the requirements that all measurements be made objectively, and that all conditions can be kept controlled across experimental trials. On the other hand, in other cases such as biology, and medicine, it is often hard to ensure that the conditions of an experiment are performed consistently; and in the social sciences, it may even be difficult to determine a method for measuring the outcomes of an experiment in an objective manner.

For this reason, sciences such as physics and several other fields of natural science are sometimes informally referred to as "hard sciences", while social sciences are sometimes informally referred to as "soft sciences"; in an attempt to capture the idea that objective measurements are often far easier in the former, and far more difficult in the latter.

Sinkhole

Sinkholes, also known as sinks, shakeholes or dolina, and cenotes, are formed by the collapse of cave roofs and are a feature of landscapes that are based on limestone bedrock. The result is a depression in the surface topography. This may range anywhere from a small, gentle earth-lined depression, to a large, cliff-lined chasm. Most often there is a small area of rock exposure near or at the bottom of a sinkhole, and a patent opening into the cave below may or may not be visible. In the case of exceptionally large sinkholes, such as Cedar Sink at Mammoth Cave National Park, there may actually be a stream or river flowing into the bottom of the sink from one side and out the other side.

Sinkholes often form in low areas where they form drainage outlets for a closed local surface drainage basin. They may also form in currently high and dry locations. Florida has been known for having frequent sinkholes, especially in the central part of the state.

Temple at Uppsala

The Temple at Uppsala was a semi-legendary cultic site in Gamla Uppsala, near modern Uppsala, Sweden, that was formed to worship the Norse gods of prehistoric times. The temple is sparsely recognized, but it is referenced in the Norse sagas and Saxo Grammaticus' Gesta Danorum. It is also described by Adam of Bremen. These images might, however, be influenced and biased by the Biblical stories and recollections of the Ancient Roman temples.

The chief controversies regarding the temple focus specifically on determining where in Old Uppsala the temple was located and whether or not it was a building. Some believe that the temple was puzzled with the hall of the Swedish kings. Churches were usually built and consecrated on top of older pagan temples and other sites that witnessed ritual behavior. During an excavation of the present church, the remains of one, and possibly several, large wooden buildings were found beneath the church's foundation.Snorri Sturluson wrote that the temple had been built by the god Freyr, who allegedly used to reside at Uppsala. Snorri and Saxo Grammaticus both claimed that it was Freyr who began the tradition of human sacrifices at the temple site. The Norse sagas, Saxo Grammaticus and Adam of Bremen describe the sacrifices at Uppsala as popular festivals that attracted people from all over Sweden. Many of these sources provide accounts of human sacrifice for the Norse gods.

Peripheral layout

The very old city inside the walls covers about four percent of the current municipality's 582 square miles. The old city is the negligible of Rome's twelve administrative zones. The walled city center is made up of 22 rioni, nearby it are 35 quartieri urbani, and within the city restrictions are six large suburban. The comune of Rome positioned outside the municipal boundaries about doubles the area of the real city.

The belt highway known as Grande Raccordo Anulare describes an enormous circle around the wealth, about six miles out from the city centre; unlike most Italian highways, the G.R.A. is toll-free. The sphere ties together the antique roads to lead to Rome: the Via Flaminia, the Via Aurelia and Via Appia. Large amounts of modern dwelling buildings are located in the districts outside the centre, where current architecture has not gone unnoticed. Many road frontages and show windows often change to keep up with the times and the Romans have succeeded in harmonising the old and the fresh.

Forms of leather

There are a number of processes whereby the skin of a dead animal can be formed into a flexible, strong material generally called leather.
Vegetable-tanned leather is tanned using tannin and further ingredients found in vegetable stuff, tree bark, and other such sources. It is flexible and brown in color, with the exact shade depending on the mix of chemicals and the color of the flesh. Vegetable-tanned fur is not stable in water; it tends to discolor, and if left to soak and then dry it will shrink and become less supple and harder. In hot water, it will shrivel drastically and plasticize, becoming rigid and ultimately becoming brittle.
Alum-tanned leather is tanned with aluminium salts assorted with a variety of binders and protein sources, such as flour, egg yolk, etc. Purists argue that alum-tanned leather is technically "tawed" and not tanned, as the resulting stuff will rot in water. Very light shades of leather are potential using this process, but the resultant material is not as supple as vegetable-tanned leather.

The bluestones
Roger Mercer has observed that the bluestones are incongruously finely worked and has suggested that they were transferred to Salisbury Plain from an as yet unlocated earlier monument in Pembrokeshire. J. F. S. Stone felt that a Bluestone monument had earlier stood near the nearby Stonehenge cursus and been moved to their current site from there. If Mercer's theory is correct then the bluestones may have been transplanted to cement an alliance or display superiority over a conquered enemy although this can only be speculation. Oval shaped settings of bluestones similar to those at Stonehenge 3iv are also known at the sites of Bedd Arthur in the Preseli Hills and at Skomer Island off the southwest coast of Pembrokeshire. Some archaeologists have suggested that the igneous bluestones and sedimentary sarsens had some symbolism, of a union between two cultures from different landscapes and therefore from different backgrounds.Recent analysis of contemporary burials found nearby known as the Boscombe Bowmen, has indicated that at least some of the individuals associated with Stonehenge 3 came either from Wales or from some other European area of ancient rocks. Petrological analysis of the stones themselves has verified that they could only have come from the Preseli Hills and it is tempting to connect the two.The main source of the bluestones is now identified with the dolerite outcrops around Carn Menyn although work led by Olwen Williams-Thorpe of the Open University has shown that other bluestones came from outcrops up to 10 km away.Aubrey Burl and a number of geologists and geomorphologists contend that the bluestones were not transported by human agency at all and were instead brought by glaciers at least part of the way from Wales during the Pleistocene. There is good geological and glaciological evidence that glacier ice did move across Preseli and did reach the Somerset coast. However, it is uncertain that it reached Salisbury Plain, and no further specimens of the unusual dolerite stone have so far been found in the vicinity. One current view is that glacier ice transported the stones as far as Somerset, and that they were collected from there by the builders of Stonehenge.

War is a disagreement involving the organized use of weapons and physical force by states or other large-scale groups. Warring parties usually hold
country, which they can win or lose; and each has a leading person or association which can surrender, or collapse, thus ending the war. Until the end of
World War II, members usually issued formal declarations of war. Other conditions for war, often used euphemistically to circumvent confines on war,
include equipped conflict, hostilities, and police action. A time when no formal war is taking place, although there may be international and interior
tensions, is sometimes called peacetime or peace. However, some think the definition of peace to be more complicated. Baruch Spinoza (1632-1677) said,
“Peace is not an absence of war, it is a virtue, a state of mind, a disposition for benevolence, confidence, justice.” Wars usually take the form of a series of
martial campaigns between two opposing sides involving a dispute over, amongst others matters, sovereignty, territory, resources, belief, or ideology. A war
to liberate an engaged country is called a "war of liberation"; a war flanked by internal factions within a state is a civil war.

Coco
Dreamed up by a youthful girl who was stranded on a desert island, Coco is a sanity challenged fantasy friend. Ever since leaving her creator, she has seemingly gone slowly insane, as illustrated through ‘My So-Called Wife’. She was in fact studied by scientists before coming to Foster's, which likely donated to her insanity. The hour-long event ‘Good Wilt Hunting’ will explore this aspect of her past. She has the head and neck of a palm tree, the body of an plane, the beak of a bird that uses a deflated raft as her mouth, and sunburned human legs and feet. Because of that, she has been called a ‘bird, airplane, plant-thing’ by some of the inhabitants. Despite being part bird and plane, we learn in ‘Foster's Goes to Europe’ that she's frightened of flying.
