An instrument for measuring the rise and fall of rivers.
1. An instrument used for the measurement of magnetic flux or the lines of magnetic force arising from and found in the vicinity of a magnetized body.
2. A meter that measures magnetic flux by the current it generates in a coil.
An instrument designed specifically for the measurement of low temperatures.
An instrument for testing taste sensation by applying an electrical stimulus to the lingual mucosa.
1. An instrument that detects, measures, and determines the direction of a small electric current.
2. An instrument that measures a small electric current by measuring the mechanical motion derived from electromagnetic or electrodynamic forces produced by the current.
Galvanometers can be used directly as ammeters, and are the core element of many ohmmeters and voltmeters.
The art or process of measuring the force of electric currents.
A gauge for measuring laughter
A reference to the measurement of an interval of time in relation to the history of the Earth and by using absolute or relative dating techniques: Geochronometric research involves the assessments of geologic time by scrutinizing isotopic radioactive decay.
geochronometry (s) (noun)
, geochronometries (pl)
An extension of geometry conceived as taking time into account as the fourth dimension; the geometry of space-time: Geochronometry uses faultless calculations of geologic time, as through isotopic-radioactive decay or radioactive elements or minerals.
, more geometrical, most geometrical
Pertaining to, or according to the rules or principles of, geometry: Little Susan drew a cat with geometrical
shapes, like triangle-shaped ears and a body which had an oval shape.
Geometrical is often used in a limited or strictly technical sense, as opposed to mechanical, therefore a construction or solution is geometrical which can be made by ruler and compasses, that is by means of right lines and circles.
, more geometrically, most geometrically
1. Regarding how something is created with simple shapes: The construction of the roof is geometrically interesting.
2. Pertaining to how geometry is put into praceice: The vines on the trellis grew quite geometrically up the side of the house.
3. Concerning how the rules or laws of geometry are applied: The students in class were very busy with calculating geometricallythe amount of space inside a given object.
geometry, counting geometry (s) (noun)
; geometries; counting geometries (pl)
1. The branch of mathematics that deals with points, lines, surfaces, and solids, and examines their properties: Geometry is a subject taught in school which is concerned with the features and relationships of points, lines, angles, curves, surfaces, and solids.
2. In nuclear medicine, any of the various arrangements between a radioactive source and a detector that affects the accuracy of counting or measurement: Counting geometry is a branch of algebraic geometry which deals with assessing the number of clarifications to geometric problems.
1. The direct or indirect measurement or approximation of the temperatures at which geologic processes take place or have taken place.
2. The study of the earth's heat and temperatures, and their effects on geologic processes.
3. The study of the earth's heat and subsurface temperatures.
4. In geology, a mineral or aggregate of minerals whose presence defines the temperature range of limits within which the minerals were formed; also known as a geologic thermometer.
