Brahmagupta's interpolation formula is a second-order polynomial interpolation formula developed by the Indian mathematician and astronomer Brahmagupta (598–668 CE) in the early 7th century CE. The Sanskrit couplet describing the formula can be found in the supplementary part of Khandakadyaka a work of Brahmagupta completed in 665 CE.
A fishing sinker or plummet is a weight used in conjunction with a fishing lure or hook to increase its rate of sink, anchoring ability, and/or casting distance. Fishing sinkers may be as small as 1 gram (0.035 oz) for applications in shallow water, and even smaller for fly fishing applications, or as large as several pounds (>1 kg) or ...
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 ...

Oscillating timekeepers are used in modern timepieces. Sundials and water clocks were first used in ancient Egypt c. 1200 BC (or equally acceptable BCE) and later by the Babylonians, the Greeks and the Chinese. Incense clocks were being used in China by the 6th century.
Āryabhaṭa's table was the first sine table ever constructed in the history of mathematics. [7] The now lost tables of Hipparchus (c. 190 BC – c. 120 BC) and Menelaus (c. 70–140 CE) and those of Ptolemy (c. AD 90 – c. 168) were all tables of chords and not of half-chords. [7] Āryabhaṭa's table remained as the standard sine table of ...

Ancient Egyptian civilization followed prehistoric Egypt and coalesced around 3100 BC (according to conventional Egyptian chronology ) [ 1 ] with the political ...
In contrast, reviewer Glen Van Brummelen writes that the book's "explanations are thorough and generally easy to understand, even for an interested lay person", and reviewer Calvin Johnsma specifically praises the book's efforts to present ancient Egyptian mathematics for what it was rather than converting it into modern forms, avoiding the ...
