BOLOMETRY Meaning and
Definition
-
Bolometry is a scientific method and a branch of physics that pertains to the measurement and analysis of electromagnetic radiation emitted by objects, typically at extremely low temperatures. It involves the use of bolometers, which are highly sensitive thermal detectors that measure the intensity or power of radiation by recording the ensuing temperature changes.
The term "bolometry" derives from the word "bolometer," which was named by its inventor, Samuel Pierpont Langley, in the late 19th century. Bolometers are constructed using a variety of materials that display significant changes in their electrical properties in response to temperature variations. A common design utilizes a fine grid or strip of material that is connected to an electric circuit. When radiation is absorbed by the bolometer, the resulting temperature rise alters the electrical resistance, which can be measured by the attached circuit.
Bolometry is applied across various fields, including astrophysics, atmospheric sciences, and quantum physics. In astronomy, bolometers play a crucial role in detecting and characterizing celestial objects by measuring the faint radiation they emit. This enables astronomers to study the temperature, composition, and behavior of these objects. Furthermore, bolometers are also found in many modern experiments aiming to detect and study dark matter and analyze cosmic microwave background radiation.
In summary, bolometry is a technique employed to measure and analyze electromagnetic radiation emitted by objects using highly sensitive thermal detectors called bolometers. It assists scientists in various fields to explore and understand the nature of radiation and its sources, contributing to advancements in astrophysics, atmospheric sciences, and quantum physics.

Etymology of BOLOMETRY
The word "bolometry" is derived from the Greek word "bolḗ", which means "throw" or "cast". The term "bolos" in Greek refers to a beam or ray, while "bolḗ" specifically signifies a missile or projectile. The suffix "-metry" comes from the Greek word "metría", meaning "measurement". In combination, "bolometry" is the measurement or analysis of the radiant energy or heat emitted by an object, often referring to the study of the intensity and distribution of such energy.
