In the third propos i t ion of the Dimensio Circuti, ARCHIMEDES established 3-~ as an upper bound , 3~7~ ° as a lower b o u n d for the ra t io of the perimeter to the diameter of the circle. EUTOCIUS remarks that APOLLONIUS derived bounds even more accurate. 1 I shall argue in the present study that ARCHIMEDES himself in t roduced such refinements, yielding bounds at least twenty times more accurate than those in the Dimensio Circuli. A close examina t ion of these computa t ions will affirm…

Archimedes used the perimeter of inscribed and circumscribed regular polygons to obtain lower and upper bounds of π. Starting with two regular hexagons he doubled their sides from 6 to 12, 24, 48,
Archimedes' dimension of the circle: A view of the genesis of the extant text
Of all the works in the Archimedean corpus, none has been more widely studied from ancient and medieval times to the present day than the short tract on the measurement of the circle. It was cited

My aim here is to describe and analyse two calculations, by John Wallis and Brook Taylor, which to modern eyes are clearly based on the approximation properties of continued fractions, though neither
Approximations of pi and squaring the circle
In this paper 18 different methods to estimate the number pi are presented. Some of the methods are the results from simple combinations of other classical approaches. The combinations usually
Controversial History of Pi in Ancient Egypt, Old Babylonia, and Ancient Greek Mathematics
We examine how the formulas of the area and the circumference of a circle related to pi in the ancient Egyptian and the Old Babylonian fields of mathematics have been controversial. In particular,
Historical stories in the mathematics classroom
Some years ago when I was co-editor of the German periodical Mathematik lehren we decided to prepare an issue on the history of mathematics. To secure the interest of our usual readership, we planned
Decision Making For Dynamic Systems Under Uncertainty: Predictions And Parameter Recomputations
This thesis is concerned with the identification of parameters of dynamic systems that ensure a specific performance or behavior and predicting the behavior of the dynamic system based on knowledge of the phenomenon in order to prevent undesired outcomes.
