Leon Battista Alberti (1404 1472) e a medida do tempo em sua obra matemática lúdica

Abstract

Currently we have many tools to help us measure various quantities (distances, heights, weights, time, etc.). However, to use them, we do not realize what it means to measure. In other terms, such instruments, mostly, does not allow us to reflect on some questions related to the concepts of what is a measure. We understand that the process of measuring a part of human activity and its approach is of great importance. Although the context of quantities and measures will be widely discussed in the early years and in the final years of primary school II, does not always allow the teacher to reflect on what is measured, since this measure has content only in their mathematical and arithmetical character. Assuming that it is important to explore the measures and quantities in their meaning, we seek to discuss this work on the measurement of time by means of an analysis of the procedures described in the work Ludic Mathematics, produced by Leon Battista Alberti (1404 - 1472) in mid-fifteenth century. Modestly, we seek here to provide math teacher a history of mathematics of the fifteenth century, based on current historiographical trends, pointing to issues that are at stake in making the history of mathematics, presenting a story that is not based on grand narratives
