Tom Duff Bell Labs Source: Jon Bentley, More Programming Pearls (Reading, Mass.: Addison-Wesley, 1988), p. 57. 2) A good fractional approximation to pi is 355/113. This is easily remembered if you note that the digits can be arranged: 113355 that is, the odd digits repeated. 3) Numerologists would be interested in this tidbit: Average Gestation Period and n * pi. ---+---------+-------------------+-------------+----------------- n | n * pi | Average gestation | No. of | Animal | | period (days) | Pregnancies | ---+---------+-------------------+-------------+----------------- 10 | 31.416 | 31.41 | 64 | English Rabbit 36 | 113.097 | 113.1 +/- 0.12 | 203 | Pig 48 | 150.796 | 150.8 +/- 0.13 | 195 | Karakul Sheep | | 150.8 =/- 0.19 | 391 | Black Forest | | | | Goat 49 | 153.038 | 154 | ? | Saanen Goat 92 | 289.026 | 288.9 | 428 | Simmental Cow ---+---------+-------------------+-------------+----------------- Source: Michael Ployani, The Logic of Liberty (1951; reprint ed., Chicago: University of Chicago Press, Midway Reprints, 1980), p. 17, reproducing a table in Nature, Vol. 146 (1940), p. 620. * * *
