Its present symbol, transmitted by Indians and Arabs, appears in Ptolemy’s trigonometric tables and in papyri from the Ptolemaic era (where it is modiﬁed by a line above or other decorations); see [Neugebauer: ESA], p. 13–14. A late mention of the role played by the number zero in arithmetic can be found in Iamblichus (In Nicomachi arithmeticam introductionem, 17–19). Iamblichus’ word for zero is , from whose ﬁrst letter may have derived the symbol we use. 8). 41 Another case where geometric algorithms fell short was that of trigonometric tables; see p.
1 Precursors of Mathematical Science 37 the real world, there may be some truth to the tradition that they regarded the discovery of incommensurability (or rather, of the impasse that led to the notion of incommensurability) as a dramatic event. If we discover that a scientiﬁc theory is contradictory, it’s no big deal: we change theories. But what can we do if we discover, or think we have discovered, a contradiction in reality itself? The widespread idea that the discovery of incommensurability shook the foundations of mathematics is based on the assumption that in the ﬁfth century B .
This is because these antecedents are not really relevant to our subject. The atomic theory of Leucippus and 29 [Heisenberg], Chapter 4. 4 Was There Science in Classical Greece? 23 Democritus, for example, has of course tremendous interest for the history of thought, but it does not seem to be a scientiﬁc theory in the sense we gave this expression in the preceding section, because, as far as we know from surviving fragments, no theorems of atomic theory were proved by the ancient atomists, nor any true experiments carried out.
