    • n radiator a mechanism consisting of a metal honeycomb through which hot fluids circulate; heat is transferred from the fluid through the honeycomb to the airstream that is created either by the motion of the vehicle or by a fan
    • n radiator heater consisting of a series of pipes for circulating steam or hot water to heat rooms or buildings
    • n radiator any object that radiates energy

  • Interesting fact: Marie Curie, the Nobel prize winning scientist who discovered radium, died of radiation poisoning
    • Radiator (Wireless Teleg) An oscillator.
    • Radiator Any of various devices for cooling an internal substance by radiation, as a system of rings on a gun barrel for cooling it, or a nest of tubes with large radiating surface for cooling circulating water, as in an automobile.
    • Radiator That which radiates or emits rays, whether of light or heat; especially, that part of a heating apparatus from which the heat is radiated or diffused; as, a steam radiator .

  • Interesting fact: The word "laser" stands for "Light Amplification by Stimulated Emission by radiation."
    • n radiator Anything which radiates; a body or substance from which rays of heat emanate or radiate.
    • n radiator A part of a heating apparatus designed to communicate heat to a room, chiefly by convection, but partly, in some cases, by radiation. A common form of radiator is a sheet-iron drum or cylinder containing deflectors or baffle-plates, placed over a fireplace to cause the volatile products of combustion to give up their heat as they pass: a heating-drum. A steam-radiator consists of a mass of coiled or flexed pipes to which steam for heating is conveyed through a continuous pipe from a boiler, and which is provided with suitable valves for the control of the steam.
    • n radiator Same as cooler, 2 .
    • n radiator In the transmission of electric waves, as in wireless telegraphy, an apparatus for the emission of electric oscillations; a form of oscillator.

  • Interesting fact: Earth's magnetic field has been weakening. It seems to have lost 15% of its strength since 1670. At the present rate of decrease, it will reach zero in 2,000 years. Between the years 3500 and 4500, the magnetic field will not be sufficiently strong enough to ward off charged radiation from outer space.
    • n Radiator a body which radiates or emits rays of light or heat: a part of a heating apparatus for a room

Where they toiled in bitter weather,
Braving rain and snow and sleet,
Gathering sticks of wood together,
We have radiators' heat.

From mysteries strange and dark and drear
To heights with joy and gladness fraught;
She radiates a luster clear.

You came into the shadow of my grief
(A lovely vision radiating light);
Your passing was as soulful and as brief
As winds among the forest pines at night.

Indifferently, 'mid public, private haunts, in solitude,
Behind the mountain and the wood,
Companion of the city's busiest streets, through the assemblage,
It and its radiations constantly glide.

Radiative Torques If the introduction of the concept of suprathermality by Purcell changed the way researchers thought of grain dynamics, the introduction of radiative torques passed essentially unnoticed.
Physics of Grain Alignment
New Life of Radiative Torques Probably the most dramatic change of the picture was the unexpected advent of radiative torques.
Physics of Grain Alignment
Weingartner (1996) to conclude that in the presence of isotropic radiation the radiative torques can support fast grain rotation long enough in order for paramagnetic torques to align grains (and without any SFM inclusions).
Physics of Grain Alignment
The radiative torques are not fixed in body coordinates and it is likely that they can provide a means for suprathermal rotation for grains that are larger than the wavelength of the incoming radiation.
