Nygaard, 1983. Object-oriented language with block structure,
coroutines, concurrency, strong typing, part objects,
separate objects and classless objects. Central feature is a
single abstraction mechanism called "patterns", a
generalisation of classes, providing instantiation and
hierarchical inheritance for all objects including procedures

(jargon) | beta
/bay't@/, /be´t@/, /bee´t@/, n.
1. Mostly working, but still under test; usu. used with “in”: in beta. In
the Real World, hardware or software systems 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.

Beta rays
(gcide) | Beta rays \Be"ta rays\ (Physics)
a form of ionizing radiation emitted by radioactive

rays, and consisting of negatively charged electrons. The
electrons are the same kind of particle as those of cathode
rays, but have much higher velocities (about 35,000 to
180,000 miles per second). They are readily deflected by a
magnetic or electric field.
[Webster 1913 Suppl.]Electron \E*lec"tron\, n. [NL., fr. Gr. 'h`lektron. See
Electric.]
1. Amber; also, the alloy of gold and silver, called
electrum. [archaic]
[1913 Webster]
2. (Physics & Chem.) one of the fundamental subatomic
particles, having a negative charge and about one
thousandth the mass of a hydrogen atom. The electron
carries (or is) a natural unit of negative electricity,
equal to 3.4 x 10^-10 electrostatic units, and is
classed by physicists as a lepton. Its mass is
practically constant at the lesser speeds, but increases
due to relativistic effects as the velocity approaches
that of light. Electrons are all of one kind, so far as is
known. Thus far, no structure has been detected within an
electron, and it is probably one of the ultimate composite
constituents of all matter. An atom or group of atoms from
which an electron has been detached has a positive charge
and is called a cation. Electrons are projected from the
cathode of vacuum tubes (including television picture
tubes) as cathode rays and from radioactive substances
as the beta rays. Previously also referred to as
corpuscle, an obsolete term. The motion of electrons
through metallic conductors is observed as an electric
current. A particle identical to the electron in mass and
most other respects, but having a positive instead of a
negative charge, is called a positron, or antielectron

(gcide) | Sugar \Sug"ar\, n. [OE. sugre, F. sucre (cf. It. zucchero, Sp.
az['u]car), fr. Ar. sukkar, assukkar, fr. Skr. [,c]arkar[=a]
sugar, gravel; cf. Per. shakar. Cf. Saccharine, Sucrose.]
1. A sweet white (or brownish yellow) crystalline substance,
of a sandy or granular consistency, obtained by
crystallizing the evaporated juice of certain plants, as
the sugar cane, sorghum, beet root, sugar maple, etc. It
is used for seasoning and preserving many kinds of food
and drink. Ordinary sugar is essentially sucrose. See the
Note below.
[1913 Webster]
Note: The term sugar includes several commercial grades, as
the white or refined, granulated, loaf or lump, and the
raw brown or muscovado. In a more general sense, it
includes several distinct chemical compounds, as the
glucoses, or grape sugars (including glucose proper,
dextrose, and levulose), and the sucroses, or true
sugars (as cane sugar). All sugars are carbohydrates.
See Carbohydrate. The glucoses, or grape sugars, are
ketone alcohols of the formula C6H12O6, and they turn
the plane of polarization to the right or the left.
They are produced from the amyloses and sucroses, as by
the action of heat and acids of ferments, and are
themselves decomposed by fermentation into alcohol and
carbon dioxide. The only sugar (called acrose) as yet
produced artificially belongs to this class. The
sucroses, or cane sugars, are doubled glucose
anhydrides of the formula C12H22O11. They are usually
not fermentable as such (cf. Sucrose), and they act
on polarized light.
[1913 Webster]
2. By extension, anything resembling sugar in taste or
appearance; as, sugar of lead (lead acetate), a poisonous
white crystalline substance having a sweet taste.
[1913 Webster]
3. Compliment or flattery used to disguise or render
acceptable something obnoxious; honeyed or soothing words.
[Colloq.]
[1913 Webster]

milk, and isomeric with sucrose. See Lactose.
Muscle sugar, a sweet white crystalline substance isomeric
with, and formerly regarded to, the glucoses. It is found
in the tissue of muscle, the heart, liver, etc. Called
also heart sugar. See Inosite.
