   The French army in the 1870s used no fewer than 425 different rope diameters for its hot air balloons. Then Captain Charles Renard devised a system that reduced the number to 17. He got the bright idea that the diameter should increase in steps governed by a certain factor rather than, for instance, by a certain width expressed in millimeters. His concept now has widespread use in technology. It is also used, approximately, in the denominations of coins and bills, as in the sequence of coins of 1, 2, 5, 10, 20, and 50 cents, 1 and 2 euros, in 16 of the 27 countries in the European Union (fig. 1.5). The ISO standard defines four base series for Renard numbers, denoted R5, R10, R20, and R40. In the R5 series, each number is larger than the preceding one by the factor #92;sqrt#91;5#93;#123;10#125;#92;approx 1.584. For practical reasons, the numbers are slightly rounded, as shown in table 1.5 for R5 and R10. They take the same structure within every decade and are evenly spread when plotted on a logarithmic scale.
