The problem, however, is that only A) as it is measured at present.

In other words, it is arbitrarily assumed that the process rate has been constant throughout the period T.

With its focus on the ancient past, archaeology somewhat resembles paleontologythe study of fossils of long-extinct animals, such as dinosaurs.

However, archaeology is distinct from paleontology and studies only past human life.

He was familiar with the work of Copernicus, and his own studies confirmed the heliocentric (sun-centered) view of the solar system.

However, in 1616 he was forbidden from teaching the truth of the Copernican view, though he was allowed to teach it as a hypothesis.

Obsidian breaks with a and is easily chipped into precise and delicate forms.

It was very widely traded from the anciently exploited sources in Hungary, Sardinia, Lipari of Sicily, Melos in the Aegean, central and eastern Anatolia, Mexico, etc.

From their studies, archaeologists attempt to reconstruct past ways of life.

If the process is not a closed system, then there may be changes in A and B which result from extraneous influences, other than those expressed in the normal rate function.

Let such changes be represented by the quantities D a and D b where D a may be either positive or negative and represents the modification in A brought about during the time T by such external influences. Putting all these quantities together, the following equations express the effect of these changes in A and B.

Archaeology also examines many of the same topics explored by historians.

But unlike historythe study of written records such as government archives, personal correspondence, and business documentsmost of the information gathered in archaeology comes from the study of objects lying on or under the ground Archaeologists refer to the vast store of information about the human past as the archaeological record.
