We explore the extent to which ancient Greek authors formulated concepts that approximate or encompass our modern notions of precision and accuracy. First, we focus on estimates and measurements of geographic features, astronomical times and positions, and weight. These raise further questions about whether the quantities reported were measured, estimated, or rounded. While ancient sources discuss the use of instruments, it is not always clear that the aim was to achieve what we would today regard as ‘precision’. Next, we briefly (...) consider round numbers, observing that they could carry symbolic meaning, while unrounded numbers could give an impression of hard-won achievement. Finally, we examine uses of the word akribeia. This is often translated as ‘precision’ or ‘exactness’, and Greek writers sometimes used akribeia to denote an ideal for their inquiries. A brief look at its uses by a number of Greek writers will on the one hand show the mismatch with our term ‘precision’, and on the other hand throw some light on the aims of Greek investigators.

Over the past twenty years or so, historians of science have become increasingly sensitized to issues involved in studying and interpreting scientific and medical instruments. The contributors to this Focus section are historians of science who have worked closely with museum objects and collections, specifically instruments used in scientific and medical contexts. Such close engagement by historians of science is somewhat rare, provoking distinctive questions as to how we define and understand instruments, opening up issues regarding the value of broken (...) or incomplete objects, and raising concerns about which scientific and medical artifacts are displayed and interpreted in museums and in what manner. It is hoped that these essays point historians of science in new directions for reengaging with scientific objects and collections. (shrink)

In theOrigin of Species, Charles Darwin (1809–82) briefly drew an analogy between languages and species, suggesting that the genealogical relationships between languages provide a model for discussing the descent and modification of species. Further, he suggested that just as languages often contain some vestige of earlier speech, for example silent, unpronounced letters, so the rudimentary organs of animals can provide clues about genealogy and descent.

Very Short Introductions: Brilliant, Sharp, Inspiring Ancient Greece is often considered to be the birthplace of science and medicine, and the explanation of natural phenomena without recourse to supernatural causes. These early natural philosophers - lovers of wisdom concerning nature - sought to explain the order and composition of the world, and how we come to know it. They were particularly interested in what exists and how it is ordered: ontology and cosmology. They were also concerned with how we come (...) to know (epistemology) and how best to live (ethics). At the same time, the scientific thinkers of early Greece and Rome were also influenced by ideas from other parts of the world, and incorporated aspects of Egyptian, Babylonian, and Indian science and mathematics in their studies. In this Very Short Introduction Liba Taub gives an overview of the major developments in early science between the 8th century BC and 6th century AD. Focussing on Greece and Rome, Taub challenges a number of modern misconceptions about science in the classical world, which has often been viewed with a modern lens and by modern scientists, such as the misconception that little empirical work was conducted, or that the Romans did not 'do' science, unlike the Greeks. Beginning with the scientific notions of Thales, Pythagoras, Parmenides and other Presocratics, she moves on to Plato and Aristotle, before considering Hellenistic science, the influence of the Stoics and Epicurean ideas, and the works of Pliny the Elder, Eratosthenes, and Ptolemy. In her sweeping discussion, Taub explores the richness and creativity of ideas concerning the natural world and its function in the ancient world, and the influence these ideas have had on later centuries. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable. (shrink)

This book provides a comprehensive overview of the key themes in Greek and Roman science, medicine, mathematics and technology. A distinguished team of specialists engage with topics including the role of observation and experiment, Presocratic natural philosophy, ancient creationism, and the special style of ancient Greek mathematical texts, while several chapters confront key questions in the philosophy of science such as the relationship between evidence and explanation. The volume will spark renewed discussion about the character of 'ancient' versus 'modern' science, (...) and will broaden readers' understanding of the rich traditions of ancient Greco-Roman natural philosophy, science, medicine and mathematics.
