Topic 1: Hellenistic mathematical sciences

# Due Date Pts Activity Time
2 Wednesday
11:59 p.m.

Topic 1 + Quiz
Background: Without a sense of context, history is anachronistic.
Primary sources: Without documentary evidence, history is speculation
The first of two topic assignments per week involving both background and primary sources.

90 min.

Aristotle, teacher of Alexander the Great, died in 322 B.C., one year after his renowned pupil. The passing of these two scientific and political giants represents a profound transition between the Classical (or Hellenic) and the later Hellenistic periods. Hellenistic natural philosophy was characterized more by the mathematical sciences than by physics or natural philosophy of the sort practiced by the presocratics. Mathematical approaches to knowing nature diversified into fields such as geometry, trigonometry, astronomy, optics, statics, and music, among others.

The intellectual centers, like the political ones, moved from Greece and Athens. Other cities achieved prominence in natural philosophy, including Alexandria in Egypt, Syrakusa in Sicily, and Pergamos in Asia Minor. In Alexandria the Ptolemaic dynasty provided lavish support for natural philosophy, among other intellectual studies, with the establishment of the unsurpassed library and the Temple to the Muses (museum).

Note on names: Don’t let the various forms of ancient names fool you: ancient Greek names are often translated in different ways. For example, Greek names often end in "-os," and Latin names often end in "-us." Where Greek names often include a "k," Latin names would substitute a hard-sounding "c." Because it was once common practice to use Latinized names, Greek names would be given in their Latin spelling. For example, "Eudoxos of Knidos" would be Latinized as "Eudoxus of Cnidus.” You will find both Latin and Greek forms of many names; I myself prefer the name that was used at the time and place under consideration; i.e., Eudoxos would refer to Eudoxos as known in his own place and time; Eudoxus would refer to later understanding of him in western, Latin-speaking Europe.

The study questions will help you assess your knowledge; print them out and complete them as you read.

  8. T or F? Hipparchos calculated the average length of the lunar month to within one second of the modern value.
  9. T or F? Alexander the Great established an empire that reached from Spain in its westernmost extent all the way to Jerusalem on its eastern border.

  14. T or F? The second head of the Lyceum, Theophrastus, rejected Aristotle’s empirical approach and renounced the pursuit of natural sciences such as botany and mineralogy, favoring the study of pure logic instead.
  15. T or F? The third head of the Lyceum, Strato, demonstrated from a stream of falling water that heavy bodies accelerate as they descend.
  16. T or F? Epicurus, founder of the Epicurean school, taught that bodies are made of particles (corpuscles or atoms) with intervening void spaces.
