david harold bailey -lrb- born 1948 -rrb- is a mathematician and computer scientist .
he received his b.s. in mathematics from brigham young university in 1972 and his ph.d. in mathematics from stanford university in 1976 .
he worked for 14 years as a computer scientist at nasa ames research center , but since 1998 has been at the lawrence berkeley national laboratory .
he is now officially retired , but continues as an active researcher .
he is a research fellow at the university of california , davis , department of computer science .
bailey is perhaps best known as a co-author -lrb- with peter borwein and simon plouffe -rrb- of a 1997 paper that presented a new formula for π -lrb- pi -rrb- .
this bailey -- borwein -- plouffe formula permits one to calculate binary or hexadecimal digits of pi beginning at an arbitrary position , by means of a simple algorithm .
the formula was discovered by simon plouffe using a computer program written by bailey .
more recently -lrb- 2001 and 2002 -rrb- , bailey and richard crandall showed that the existence of this and similar formulas has implications for the long-standing question of `` normality '' -- whether and why the digits of certain mathematical constants -lrb- including pi -rrb- appear `` random '' in a particular sense .
bailey is a long-time collaborator with jonathan borwein -lrb- peter 's brother -rrb- .
they are co-authors of numerous papers and three books on experimental mathematics .
bailey also does research in numerical analysis and parallel computing .
he has published studies on the fast fourier transform , high-precision arithmetic , and the pslq algorithm -lrb- used for integer relation detection -rrb- .
he is a co-author of the nas benchmarks , which are used to assess and analyze the performance of parallel scientific computers .
he has also published articles in the area of mathematical finance , including a 2014 paper `` pseudo-mathematics and financial charlatanism , '' which emphasizes the dangers of backtest overfitting in the financial field .
in 1993 , bailey received the sidney fernbach award from the ieee computer society , as well as the chauvenet prize and the hasse prize from the mathematical association of america .
in 2005 he was a finalist for the $ 100,000 edge of computation science prize .
in 2008 he was a co-recipient of the gordon bell prize from the association for computing machinery .
in addition to bailey 's technical work in mathematics , computer science , bailey has written articles on science and religion , emphasizing the pointlessness of war between science and religion .
bailey is the editor of the science meets religion website , a repository of articles and information on issues at the juncture of science and religion .
bailey is affiliated with the church of jesus christ of latter-day saints .
