-ics, -tics [-ac after i]

(Greek: a suffix that forms nouns and is usually used to form names of arts and sciences)

atmiatry, atmiatrics
The treatment of disease by vapors or gases, as by inhalation.
atmoclastics (pl) (noun)
1. Residual rocks that are formed in place by disintegration and decomposition with little or no rearranging.
2. A reference to the study of clastic rocks or rock fragments broken by atmospheric weathering and recemented in the same pattern as the previous arrangement.
3. The fragments of rocks that are broken off in place by atmospheric weathering and which have been recemented without rearrangement.
atmometrics
A reference to a process of measuring the rate of evaporation of water into the atmosphere.

Atmometrics involves the measuring of the evaporation of water from a free water surface; such as, a pan of water set into the ground so the water's surface is even with the ground's surface, or from a porous, water-saturated surface; such as, filter paper placed over a graduated cylinder of water.

atmospheric acoustics (s) (noun) (a plural form used as a singular)
The propagation of sound through the layer of gases surrounding the earth's surface, which affects sound in predictable ways depending on conditions; such as, temperature and precipitation: "When setting up for the outdoor concert, the sound engineers had to take atmospheric acoustics into consideration including factors such as moisture in the air, placement of speakers on the ground, etc."
atmospheric interference (s) (noun), atmospheric interferences (pl)
1. Electromagnetic radiation, caused by natural electrical disturbances in the atmosphere, which interferes with radio systems; also known as atmospherics or strays.
2. The radio frequency electromagnetic radiation originating, principally, in the irregular surges of charge in thunderstorm lightning discharges.

Atmospherics are heard as a quasi-steady background of crackling noise (static) on certain radio frequencies; such as, those used to broadcast AM radio signals.

Since any acceleration of electric charge leads to emission of electromagnetic radiation, and since the several processes involved in propagation of lightning lead to very large charge accelerations, the lightning channel acts like a huge transmitter, sending out radiation with frequencies of the order of 10 kHz.

atmospheric optics (s) (noun) (a plural form used as a singular)
1. A branch of meteorological physics or physical meteorology in which phenomena are seen occurring in the sky and are described and explained.
2. The study of the optical characteristics of the atmosphere or products of atmospheric processes.

The term is usually confined to visible and near visible radiation; however, unlike meteorological optics, it routinely includes temporal and spatial resolutions beyond those discernible with the naked eye.

Meteorological optics is that part of atmospheric optics concerned with the study of patterns observable with the naked eye.

This restriction is often relaxed slightly to allow the use of simple aids; such as, binoculars or a polarizing filter.

Topics included in meteorological optics are sky color, mirages, rainbows, halos, glories, coronas, and shines.

atmospheric physics (s) (noun) (a plural form used as a singular)
A branch of science dealing with the investigation and study of the physical phenomena of the atmosphere.
atmospherics, spherics
1. Electromagnetic radiation produced by natural phenomena; such as, lightning.
2. Atmospheric disturbances of electrical origin causing interference with communication in wireless telegraphy, television, etc.
3. Atmospheric conditions caused by electromagnetic disturbances; especially, as they affect radio transmission.
atomic physics
A profession in the area of physics concerned with the scientific structures of the atom, the characteristics of the electrons and other elementary particles of which the atom is composed, the arrangement of the atom's energy states, and the processes involved in the radiation of light and x-rays.
autoclastics (adjective)
1. Broken in place, said of rocks having a broken or brecciated (rocks with sharp-angled fragments) structure due to crushing, in contrast to those of brecciated materials brought from a distance.
2. Of rock, fragmented in place by folding due to orogenic forces when the rock is not so heavily loaded as to render it plastic.
avionics (pl) (noun) (used as a singular verb)
The science and technology of electronics and the development of electronic devices as applied to aeronautics and astronautics: Avionics has also become even more important with the production and applications to other forms of aviation and rocketry.
balaneutics
Balneology; the science of baths or bathing, especially the study of the therapeutic use of mineral baths.
ballistics
1. The scientific study of the movement and flight characteristics of projectiles of objects or weapons that are fired into the air.
2. The science of flight dynamics and the trajectory of an object in free flight.
balneotherapeutics
Treatments of variouis ailments and diseases with the use of mineral, thermo, and other kinds of baths.
bariatrics, bariatric
1. That branch of medicine concerned with the management (prevention or control) of obesity and allied diseases.
2. The field of medicine that offers treatment for the person who is overweight with a comprehensive program including diet and nutrition, exercise, behavior modification, lifestyle changes and, when indicated, the prescription of appetite suppressants and other appropriate medications.

Bariatrics also includes research into overweight, its causes, prevention, and treatment.
