David H. Bailey (mathematician)

David Harold Bailey (born 1948) 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.[1] He worked for 14 years as a computer scientist at NASA Ames Research Center, and then from 1998 to 2013 as a Senior Scientist at the Lawrence Berkeley National Laboratory. He is now retired from the Berkeley Lab, but continues as a Research Associate at the University of California, Davis, Department of Computer Science.

Bailey is perhaps best known as a co-author (with Peter Borwein and Simon Plouffe) of a 1997 paper that presented a new formula for π (pi), which had been discovered by Plouffe in 1995. 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. Subsequently, 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 (including pi) appear "random" in a particular sense.

Bailey is a long-time collaborator with the late Jonathan Borwein (Peter's brother). They co-authored five books and over 80 technical papers 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 (used for integer relation detection). 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 statistical overfitting and other abuses of mathematics in the financial field.

In 1993, Bailey received the Sidney Fernbach award from the IEEE Computer Society, as well as the Chauvenet Prize[2] and the Hasse Prize from the Mathematical Association of America. In 2008 he was a co-recipient of the Gordon Bell Prize from the Association for Computing Machinery. In 2017 he was a co-recipient of the Levi L. Conant Prize from the American Mathematical Society.

Bailey is a member of The Church of Jesus Christ of Latter-day Saints. He has positioned himself as an advocate of the teaching of science and that accepting the conclusions of modern science is not incompatible with a religious view.[3]

gollark: That would be "very fast", yes.
gollark: I simply type very fast.
gollark: An alternative to using CD or USB images for installation is to use the static version of the package manager Pacman, from within another Linux-based operating system. The user can mount their newly formatted drive partition, and use pacstrap (or Pacman with the appropriate command-line switch) to install base and additional packages with the mountpoint of the destination device as the root for its operations. This method is useful when installing Arch Linux onto USB flash drives, or onto a temporarily mounted device which belongs to another system. Regardless of the selected installation type, further actions need to be taken before the new system is ready for use, most notably by installing a bootloader and configuring the new system with a system name, network connection, language settings, and graphical user interface. The installation images come packaged with an experimental command line installer, archinstall, which can assist with installing Arch Linux.
gollark: Arch is largely based on binary packages. Packages target x86-64 microprocessors to assist performance on modern hardware. A ports/ebuild-like system is also provided for automated source compilation, known as the Arch Build System. Arch Linux focuses on simplicity of design, meaning that the main focus involves creating an environment that is straightforward and relatively easy for the user to understand directly, rather than providing polished point-and-click style management tools — the package manager, for example, does not have an official graphical front-end. This is largely achieved by encouraging the use of succinctly commented, clean configuration files that are arranged for quick access and editing. This has earned it a reputation as a distribution for "advanced users" who are willing to use the command line. The Arch Linux website supplies ISO images that can be run from CD or USB. After a user partitions and formats their drive, a simple command line script (pacstrap) is used to install the base system. The installation of additional packages which are not part of the base system (for example, desktop environments), can be done with either pacstrap, or Pacman after booting (or chrooting) into the new installation.
gollark: On March 2021, Arch Linux developers were thinking of porting Arch Linux packages to x86_64-v3. x86-64-v3 roughly correlates to Intel Haswell era of processors.
