  • n. Transmission; conveyance; specifically, in physics, transmission of heat from points of high temperature to points of low temperature, or of electricity from points of high potential to points of low potential, from particle to particle, and to a distance, by the raising of the temperature or potential of intermediate particles, without any sensible motion of them.
  • n. In physiology, the transfer of nervous influence along a nerve-fiber or of the contractile force from point to point in muscle-tissue.

Latin conductio ("a bringing together").


  • Hereafter, perhaps, all these modes may appear as the result of one common principle, but at present they require to be considered apart; and I will now speak of the _first_ mode, for amongst all the forms of discharge, that which we express by the term conduction appears the most simple and the most directly in contrast with insulation.

  • BUTCH MORRIS, who has been doing what he calls "conduction" for a quarter-century, has a residency at Lucky Cheng's with his 19-piece

  • A 1D heat conduction is solved numerically for fluxes in and out of surfaces.

  • This particular conduction is non-sexual, although the vast majority of conductions include sex.

    Interview with Catherine Spangler

  • This belief, in conduction with the distaste for direct confrontation, often leads to a passive-aggressive response to the foreign executive's orders or requests (in the form of forgetting, procrastinating, or not following through).

    Mexico - The Social Perspective

  • When thermal energy is exchanged from one particle to a nearby one by means of a collision or a movement that induces movement for example, through electrical attraction or repulsion, the process is called conduction.

  • In semiconductors, electron mobility is strongly reduced because there are forbidden regions for the energy of the electrons that take part in conduction, the "energy gaps".

  • ROWLAND: Now this device will not help all heart failure patients; they estimates perhaps half of those, and it will be those with what's called a conduction delay.

  • Of the two modes in which bodies can transmit the electric forces, namely, that which is so characteristically exhibited by the metals, and usually called conduction, and that in which it is accompanied by decomposition, the first appears common to all bodies, although it occurs with almost infinite degrees of difference; the second is at present distinctive of the electrolytes.

    Experimental Researches in Electricity, Volume 1

  • In a semiconductor crystal, an excited electron - one that's had energy added to it - will break free and enter the so-called conduction band, where it can move freely around the crystal.
