A-C

Atomic mass number: The integer closest to the isotopic mass of a nuclide = the total number of protons and neutrons combined.

acceleration: A change in observed magnitude or direction of motion.  Units are meters/second/second in the MKS system,
centimeters/second/second in the CGS system and feet/second /second in the
English system.

ad hoc: [Latin] Regarding a particular thing, for a specific purpose, case or situation.  In logic an ad hoc explanation is one
that is tailored for one case or instance only, a special pleading.

articulated: In paleontology, when bones are found together in their joints, in their
original relationships.

atomic mass: The measure of the quantity of matter in an atom, which is mostly in the
atom’s nucleus.  The simplest atomic
nucleus is ordinary hydrogen, which has a single proton as its nucleus, and thus
it has an atomic mass very close to of 1.  Both
protons (each with one positive electric charge) and neutrons (with no electric
charge) have atomic masses very close to one.
An atom of ordinary carbon has 6 protons and 6 neutrons in its nucleus,
and has an atomic mass now defined to be exactly 12 atomic mass units, carbon 12
being the standard for atomic mass measures.  The atomic mass unit [amu] is 1/12 of the mass of a carbon 12
nucleus, or 1.66032 x 10-27 kg.

atomic species: a particular chemical element, specified by the number of protons in
the atomic nucleus, regardless of the number of neutrons.  For example, all hydrogen atoms have one
proton, all helium atoms have two protons, all carbon atoms have six protons,
all nitrogen atoms have seven protons.

atomic number: Z,  The number of positive
electric charges in the nucleus of an atom, the number of protons in the
nucleus.  All atoms with the same Z
are said to be of the same chemical element, regardless of the number of
neutrons in the nucleus.

basement rocks: Rocks at the lowest level, which presumably were present before any
sedimentary process layed down rocks above, or igneous processes disturbed the
region.

blind study: [in bio-medical research] A study in which the subject of the experiment
[animal or human] does not know whether the treatment or substance given is an
active agent or a placebo.

carbon 12: The ordinary form of carbon, the most abundant form of carbon.  The nucleaus of a cabon 12 atom has an
atomic mass [A] of 12, made up 6 protons [Z] and 6 neutrons, and the nucleus is
surrounded by 6 electrons.

carbon 14: A rare radioactive form of carbon.  The
nucleus of a carbon 14 atom has an atomic mass of 14, made up of 6 protons [Z]
and 8 neutrons, and the nucleus is surrounded by 6 electrons.  Carbon 14 decays [splits apart] when its
nucleus emits an electon converting one of the neutrons int a proton.  The result is an ordinary nitrogen atom
[with 7 protons and 7 neutrons and 7 electrons].

cause: That which produces an effect, a result or a consequence.  v. To make happen. To bring about.

compound nucleus:  [in nuclear physics] An excited nucleus, having excess energy, which
lasts a short time as an intermediate step in a nuclear reaction.

science phenomena can generally be reproduced.
Sometimes blind or double blind studies are used to eliminate the
possibility of experimenter bias in the evaluation of results.  Empirical science is generally
repeatable and verifiable in more than one laboratory and/or by more than one
independent researcher.  Most
empirical science is true science because most empirical science is
repeatable, precisely limited, and falsifiable.

the combined mass of the protons and neutrons therein, minus the equivalent mass
of the binding energy which holds the nucleus together.

 

 

nuclide =
[in nuclear physics] A particular nuclear species.  A term synonymous with isotope.  Each unique combination of protons and
neutrons forming the nucleus of an atom is called a nuclide, isotope.

 

 

observational
science = Science that deals with phenomena that are not readily controlled by
or accessible to the scientist or observer.
Examples include much or geology, astronomy, and history; and some areas
of psychology and biology.  In such
areas of study the studied phenomena: 1) are one time events which are not
repeatable or controllable, 2) occur in the inaccessible past or future, or 3)
occur in regions out of the reach of scientists, such as the center of the
earth, the center of a star, or a remote region of the universe, or even in
other universes not seen.  Observational
science is really modeling and speculation, and is not therefore empirical-
experimental science, since in such circumstances there are severe limitations
on observation and falsifiability.  The
pivotal difference between empirical & observational science is the extent
to which the scientist-researcher can control or reproduce the phenomena being
observed.  Often in observational
science multiple layers of inference and untestable assumptions are necessary
before any conclusion can be reached.

same general mineral type and composition throughout, presumably originally
horizontal [no matter how presently deformed or oriented], especially one of a

is, when predictions fail, or contrary facts are recognized, then a statement of
true science can be falsified.  True
science is also clearly defined and limited in its scope of application; that
is, where and when its concepts should be applicable.

gravitating bodies, or on a frictionless horizontal surface.

 

W-Z

world view: The system of concepts, ideas and presuppositions which set boundaries on what
is acceptable as true to an individual.  Such
ideas and presuppositions limit the thinking of the individual when seeking
understanding of processes and events, and limit which may be accepted as facts
and thus included when understanding the meaning of the world.

 

 

Z = The atomic number: the number of positive electric charges on the nucleus of the
atom, the number of protons in the nucleus.
