-ics, -tics [-ac after i]

In the most general sense, any tools made of stone.

Although stone-tool-dependent cultures exist even today, most stone tools are associated with prehistoric societies that no longer exist.

The art of printing colored pictures on canvas from oil paintings on stone.

1. Sailing on loxodromes or oblique lines on a map.
2. The art of oblique sailing.

1. The study of the prolongation or extension of life; long-lived.
2. The theory or practice of promoting well-being and longevity, principally by means of a diet consisting chiefly of whole grains and beans.

1. A branch of economics that focuses on the general features and processes that make up a national economy and the ways in which different segments of the economy are connected (takes a singular verb).
2. A branch of economics dealing with the broad and general aspects of an economy; such as, the relationship between the income and investments of a country as a whole.

This is the field of economics that studies the behavior of the aggregate economy including economy-wide phenomena; such as, changes in unemployment, national income, rate of growth, gross domestic product, inflation, and price levels.

Macroeconomics is focused on the movement and trends in the economy as a whole, while in microeconomics the focus is placed on factors that affect the decisions made by firms and individuals.

The factors that are studied by macro and micro will often influence each other; for example, the current level of unemployment in the economy as a whole will affect the supply of workers which an oil company can hire from.

The branch of physics dealing with magnetic phenomena that are constant in time.

The attempt to treat a disease by the application of magnets to the surface of the body.

The use of specific magnetic fields to accelerate healing and reduce pain. The pain relieving and healthy benefits of magnotherapy are supposed to be the result of a change in the body’s pH levels caused by magnetic energy.

1. Obstetrics, the branch of medicine dealing with childbirth and the care of the mother.
2. The art of giving birth; such as, clearness and conviction, to ideas, which are conceived as struggling for birth.

1. A science (or group of related sciences) dealing with the logic of quantity and shape and arrangement.
2. The study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols.
3. The systematic treatment of magnitude, relationships between figures and forms, and relations between quantities expressed symbolically.

The etymology of mathematics.

1. The branch of physics that seeks to formulate general rules for predicting the behavior of a physical system under the influence of any type of interaction with its environment: "Mechanics generally involves the motion of large objects."

"Mechanics deals with motion and with the reaction of physical systems with internal and external forces which produce movements."

"The field of mechanics is subdivided into statics and dynamics; depending on the types of systems and phenomena that are involved."

• Dynamics is usually subdivided into kinematics (motion without reference to force or mass) and kinetics (forces that cause motions of bodies).
• Statics deals with bodies at rest.

2. The machinery or working parts of something: "Barney, the mechanic, checks out the mechanics of a car before he does anything with the non-mechanical aspects."
3. The procedure involved when something is done or used: "Jerry was receiving instructions regarding the mechanics of his musical instrument."

Gymnastic conditioning done with mechanical devices; such as, a system of levers and pulleys designed to provide manipulation and exercises for the body and limbs: Tom does mechanogymnastics as often as possible in the local fitness studio in order to maintain a better physical status.

The mechanical systems within an organism.

The extensive mechanization of a society with a highly developed technology.

The "systematic study of chemical fingerprints that specific cellular processes leave behind"; specifically, the study of their small-molecule metabolite profiles.

The metabolome represents the collection of all metabolites in a biological cell, tissue, organ, or organism, which are the end products of cellular processes.
