This is an important technique for all types of time series analysis, especially for seasonal adjustment. [2] It seeks to construct, from an observed time series, a number of component series (that could be used to reconstruct the original by additions or multiplications) where each of these has a certain characteristic or type of behavior.
Timelines are particularly useful for studying history, as they convey a sense of change over time. Wars and social movements are often shown as timelines. Timelines are also useful for biographies. Examples include: Timeline of the civil rights movement; Timeline of European exploration; Timeline of European imperialism
In historiography, periodization is the process or study of categorizing the past into discrete, quantified, and named blocks of time for the purpose of study or analysis. [ 1 ] [ 2 ] This is usually done to understand current and historical processes, and the causality that might have linked those events.
Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events". [3] Chronology is a part of periodization. It is also a part of the discipline of history including earth history, the earth sciences, and study of the geologic time scale.
The decomposition of food, either plant or animal, called spoilage in this context, is an important field of study within food science. Food decomposition can be slowed down by conservation. The spoilage of meat occurs, if the meat is untreated, in a matter of hours or days and results in the meat becoming unappetizing, poisonous or infectious.
These timelines of world history detail recorded events since the creation of writing roughly 5000 years ago to the present day. For events from c. 3200 BC – c. 500 see: Timeline of ancient history; For events from c. 500 – c. 1499, see: Timeline of post-classical history; For events from c. 1500, see: Timelines of modern history
The date used as the end of the ancient era is arbitrary. The transition period from Classical Antiquity to the Early Middle Ages is known as Late Antiquity.Late Antiquity is a periodization used by historians to describe the transitional centuries from Classical Antiquity to the Middle Ages, in both mainland Europe and the Mediterranean world: generally from the end of the Roman Empire's ...
History didn't start with the first humans—they were cavemen! The Stone Age wasn't history; the Stone Age was a preamble to history, a dystopian era of stasis before the happy onset of civilization, and the arrival of nifty developments like chariot wheels, gunpowder, and Google. History started with agriculture, nation-states, and written ...
