  • apple computer, inc. — (company)   Manufacturers of the Macintosh range of personal computers as well as the earlier Apple I, Apple II and Lisa. Founded on 1 April 1976 by Steve Jobs and Steve Wozniak. Apples were among the first microcomputers. They originally used the 6502 processor and are still being made (August 1994), now using the 65816. The Apple II line, which includes the Apple I, is the longest existing line of microcomputers. Steve Jobs left Apple (involuntarily) and started NeXT and later returned when Apple bought NeXT in late 1997(?). Quarterly sales $2150M, profits $138M (Aug 1994). http://apple.com/.

  • axiomatic set theory — (theory)   One of several approaches to set theory, consisting of a formal language for talking about sets and a collection of axioms describing how they behave. There are many different axiomatisations for set theory. Each takes a slightly different approach to the problem of finding a theory that captures as much as possible of the intuitive idea of what a set is, while avoiding the paradoxes that result from accepting all of it, the most famous being Russell's paradox. The main source of trouble in naive set theory is the idea that you can specify a set by saying whether each object in the universe is in the "set" or not. Accordingly, the most important differences between different axiomatisations of set theory concern the restrictions they place on this idea (known as "comprehension"). NBG (von Neumann-Bernays-Goedel) set theory sort of allows comprehension for all formulae without restriction, but distinguishes between two kinds of set, so that the sets produced by applying comprehension are only second-class sets. NBG is exactly as powerful as ZF, in the sense that any statement that can be formalised in both theories is a theorem of ZF if and only if it is a theorem of ZFC. MK (Morse-Kelley) set theory is a strengthened version of NBG, with a simpler axiom system. It is strictly stronger than NBG, and it is possible that NBG might be consistent but MK inconsistent. ML ("Modern Logic") is to NF as NBG is to ZF. (Its name derives from the title of the book in which Quine introduced an early, defective, form of it). It is stronger than ZF (it can prove things that ZF can't), but if NF is consistent then ML is too.

  • basal metabolic rate — the rate at which heat is produced by the body at rest, 12 to 14 hours after eating, measured in kilocalories per square metre of body surface per hour
  • basic encoding rules — (protocol, standard)   (BER) ASN.1 encoding rules for producing self-identifying and self-delimiting transfer syntax for data structures described in ASN.1 notations. BER is an self-identifying and self-delimiting encoding scheme, which means that each data value can be identified, extracted and decoded individually. Huw Rogers once described BER as "a triumph of bloated theory over clean implementation". He also criticises it as designed around bitstreams with arbitrary boundaries between data which can only be determined at a high level. Documents: ITU-T X.690, ISO 8825-1. See also CER, DER, PER.
  • basic lead carbonate — ceruse.
  • basic object adapter — (architecture)   (BOA) Part of the CORBA architecture.

  • benzene hexachloride — a compound, C6H6Cl6, used as an insecticide
  • benzenesulfonic acid — a fine, needlelike substance, C 6 H 6 SO 3 , used chiefly as a catalyst and in the synthesis of phenol, resorcinol, and other organic products.
  • bernard of clairvaux — Saint. ?1090–1153, French abbot and theologian, who founded the stricter branch of the Cistercians in 1115
  • binary coded decimal — (data)   (BCD, packed decimal) A number representation where a number is expressed as a sequence of decimal digits and then each decimal digit is encoded as a four-bit binary number (a nibble). E.g. decimal 92 would be encoded as the eight-bit sequence 1001 0010. In some cases, the right-most nibble contains the sign (positive or negative). It is easier to convert decimal numbers to and from BCD than binary and, though BCD is often converted to binary for arithmetic processing, it is possible to build hardware that operates directly on BCD.
  • binary-coded decimal — a number in binary code written in groups of four bits, each group representing one digit of the corresponding decimal number
  • binomial coefficient — any of the numerical factors which multiply the successive terms in a binomial expansion; any term of the form n!/(n–k)!k!: written (nk), nCk, or Cnk
