The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. [1] Protoscience, early sciences, and natural philosophies such as alchemy and astrology during the Bronze Age, Iron Age, classical antiquity, and the Middle Ages declined ...
Copernican Revolution Age of Enlightenment. The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
Historic recurrence is the repetition of similar events in history. [a] [b] The concept of historic recurrence has variously been applied to overall human history (e.g., to the rises and falls of empires ), to repetitive patterns in the history of a given polity, and to any two specific events which bear a striking similarity.

Historical method is the collection of techniques and guidelines that historians use to research and write histories of the past. Secondary sources, primary sources and material evidence such as that derived from archaeology may all be drawn on, and the historian's skill lies in identifying these sources, evaluating their relative authority, and combining their testimony appropriately in order ...
The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [5] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...
The trend component does not have to be linear., the cyclical component at time t, which reflects repeated but non-periodic fluctuations. The duration of these fluctuations depend on the nature of the time series., the seasonal component at time t, reflecting seasonality (seasonal variation). A seasonal pattern exists when a time series is ...
In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of ...
1950 – Research based on the double blind test is published for the first time, by Greiner et al. 1962 – The American physicist Thomas S. Kuhn publishes his book The Structure of Scientific Revolutions, which controversially challenged powerful and entrenched philosophical assumptions about the progress of science through history.
