  • carl friedrich gauss — (person)   A German mathematician (1777 - 1855), one of all time greatest. Gauss discovered the method of least squares and Gaussian elimination. Gauss was something of a child prodigy; the most commonly told story relates that when he was 10 his teacher, wanting a rest, told his class to add up all the numbers from 1 to 100. Gauss did it in seconds, having noticed that 1+...+100 = 100+...+1 = (101+...+101)/2. He did important work in almost every area of mathematics. Such eclecticism is probably impossible today, since further progress in most areas of mathematics requires much hard background study. Some idea of the range of his work can be obtained by noting the many mathematical terms with "Gauss" in their names. E.g. Gaussian elimination (linear algebra); Gaussian primes (number theory); Gaussian distribution (statistics); Gauss [unit] (electromagnetism); Gaussian curvature (differential geometry); Gaussian quadrature (numerical analysis); Gauss-Bonnet formula (differential geometry); Gauss's identity (hypergeometric functions); Gauss sums (number theory). His favourite area of mathematics was number theory. He conjectured the Prime Number Theorem, pioneered the theory of quadratic forms, proved the quadratic reciprocity theorem, and much more. He was "the first mathematician to use complex numbers in a really confident and scientific way" (Hardy & Wright, chapter 12). He nearly went into architecture rather than mathematics; what decided him on mathematics was his proof, at age 18, of the startling theorem that a regular N-sided polygon can be constructed with ruler and compasses if and only if N is a power of 2 times a product of distinct Fermat primes.

  • channel service unit — (communications)   (CSU) A type of interface used to connect a terminal or computer to a digital medium in the same way that a modem is used for connection to an analogue medium. A CSU is provided by the communication carrier to customers who wish to use their own equipment to retime and regenerate the incoming signals. The customer must supply all of the transmit logic, receive logic and timing recovery in order to use the CSU, whereas a digital service unit DSU performs these functions.

  • commonwealth hackish — (jargon)   Hacker jargon as spoken outside the US, especially in the British Commonwealth. It is reported that Commonwealth speakers are more likely to pronounce truncations like "char" and "soc", etc., as spelled (/char/, /sok/), as opposed to American /keir/ and /sohsh/. Dots in newsgroup names (especially two-component names) tend to be pronounced more often (so soc.wibble is /sok dot wib'l/ rather than /sohsh wib'l/). The prefix meta may be pronounced /mee't*/; similarly, Greek letter beta is usually /bee't*/, zeta is usually /zee't*/, and so forth. Preferred metasyntactic variables include blurgle, "eek", "ook", "frodo", and "bilbo"; "wibble", "wobble", and in emergencies "wubble"; "banana", "tom", "dick", "harry", "wombat", "frog", fish, and so on and on (see foo). Alternatives to verb doubling include suffixes "-o-rama", "frenzy" (as in feeding frenzy), and "city" (examples: "barf city!" "hack-o-rama!" "core dump frenzy!"). Finally, note that the American terms "parens", "brackets", and "braces" for (), [], and {} are uncommon; Commonwealth hackish prefers "brackets", "square brackets", and "curly brackets". Also, the use of "pling" for bang is common outside the United States. See also attoparsec, calculator, chemist, console jockey, fish, go-faster stripes, grunge, hakspek, heavy metal, leaky heap, lord high fixer, loose bytes, muddie, nadger, noddy, psychedelicware, plingnet, raster blaster, RTBM, seggie, spod, sun lounge, terminal junkie, tick-list features, weeble, weasel, YABA, and notes or definitions under Bad Thing, barf, bum, chase pointers, cosmic rays, crippleware, crunch, dodgy, gonk, hamster, hardwarily, mess-dos, nibble, proglet, root, SEX, tweak and xyzzy.
  • commune with oneself — to think; ponder
  • comprehensive school — a secondary school for children of all abilities from the same district
  • computability theory — (mathematics)   The area of theoretical computer science concerning what problems can be solved by any computer. A function is computable if an algorithm can be implemented which will give the correct output for any valid input. Since computer programs are countable but real numbers are not, it follows that there must exist real numbers that cannot be calculated by any program. Unfortunately, by definition, there isn't an easy way of describing any of them! In fact, there are many tasks (not just calculating real numbers) that computers cannot perform. The most well-known is the halting problem, the busy beaver problem is less famous but just as fascinating.
