\be"ta\ (?), n. [gr. bh^ta.] the second letter of the greek alphabet, b, ?. see b, and cf. etymology of alphabet.
note: beta (b, ?) is used variously for classifying, as: (a) (astron.) to designate some bright star, usually the second brightest, of a constellation, as, ? aurig?. (b) (chem.) to distinguish one of two or more isomers; also, to indicate the position of substituting atoms or groups in certain compounds; as, ?-naphthol. with acids, it commonly indicates that the substituent is in union with the carbon atom next to that to which the carboxyl group is attached.

Raynet Business & Marketing Glossary
  1. Mostly working, but still under test; usually used with `in': `in beta'. In the Real World, systems (hardware or software) software often go through two stages of release testing: Alpha (in-house) and  Beta (out-house?).   2. Anything that is new and experimental. 3. Flaky; dubious; suspect (since beta software is notoriously buggy).

ROLLASON Beta L1P L
ASTRONOMY UNBOUND
A high speed electron emitted in a form of radioactive disintegration from an atomic nucleus which has a surfeit of electric charge and energy. The mechanism involves the conversion of one type of nucleon  into another and the creation of an electron ( no  electrons can exist in the nucleus (the so-called Klein paradox  )). The beta particle is emitted at high speed at any one energy up to a maximum which is unique to the radio-nuclide. Likewise the half life is characteristic. Energy is conserved by the simultaneous emission of a neutrino with very little (or no mass) that travels close to (or at the speed of light). An example of the equation of 'nuclear chemistry' that illustrates negative beta decay is the deacy of tritium with a 13 year half-life 1H3 -> 2He3 + -e + antineutrino
If the electron emitted is the antimatter counterpart or positron then there must first be an excess of internal energy in the nucleus greater than the rest mass energy of two electrons (i.e. 2 m c2). An 'ordinary' matter neutrino shares energy with the positive electron. For example: 8O15 + (2 m c2) -> 7N15 + +e + neutrino
. A star which infrared observations showed to have a dusty disc of material around it. Although originally thought to be an accretion disc, from which planets form, the dimensions of the disc are far too large for that to be the answer. With a diameter of ten times that of Pluto's orbit, current ideas indicate that the disc may be a Kuiper belt .

An Everquest Glossary
(n.) The period before Everquest was released to the general public, during which only a comparative handful of folks could play the game (for testing purposes). Usually used to indicate lengthy experience with Everquest, e.g. "Look, I've been around since the 3rd phase of beta, and I'm telling you that Equestrielle has always spawned in LFay!" cf. commercial release.
Jargon File
/bay't*/, /be't*/ or (Commonwealth) /bee't*/ n.

1. Mostly working, but still under test; usu. used with `in': `in beta'. In the Real World, systems (hardware or software) software often go through two stages of release testing: Alpha (in-house) and Beta (out-house?). Beta releases are generally made to a group of lucky (or unlucky) trusted customers. 2. Anything that is new and experimental. "His girlfriend is in beta" means that he is still testing for compatibility and reserving judgment. 3. Flaky; dubious; suspect (since beta software is notoriously buggy).

Historical note: More formally, to beta-test is to test a pre-release (potentially unreliable) version of a piece of software by making it available to selected (or self-selected) customers and users. This term derives from early 1960s terminology for product cycle checkpoints, first used at IBM but later standard throughout the industry. `Alpha Test' was the unit, module, or component test phase; `Beta Test' was initial system test. These themselves came from earlier A- and B-tests for hardware. The A-test was a feasibility and manufacturability evaluation done before any commitment to design and development. The B-test was a demonstration that the engineering model functioned as specified. The C-test (corresponding to today's beta) was the B-test performed on early samples of the production design, and the D test was the C test repeated after the model had been in production a while.
