	Is Dna an Electrical Conductor \| Science in Dispute
		To describe an individual molecule as a conductor requires carefully defining what being a conductor might mean on a molecular level.
		The most common form of electrical conductor is a macroscopic piece of a metallic element or alloy.

		Boston Pops conductor Keith Lockhart, five members of the orchestra, and 50 audience members were the guinea pigs -- wired with sensors as researchers stationed at two banks of computers backstage collected data about heart rates, muscle movement, and other physiological responses.
		"Science has come an awful long way in the last 250 years," Boston Pops conductor Keith Lockhart told a Symphony Hall audience of about 2,000 parents and young children during a family concert.
		"If the conductor is conveying excitement, we expect to see that in the musicians, and a second or two later in the audience," Levitin continued.

	Electrical conductor - Wikipedia, the free encyclopedia
		When an electric potential difference is impressed across separate points on a conductor, the mobile charges within the conductor are forced to move, and an electric current between those points appears in accordance with Ohm's law.
		A conductor of a given material and volume (length x cross-sectional area) has no real limit to the current it can carry without being destroyed as long as the heat generated by the resistive loss is removed and the conductor can withstand the radial forces.
		Conductors are usually surrounded by and/or supported by insulators and the insulation determines the maximum voltage that can be applied to any given conductor.

		To do this the conductor should lead the way into collective awareness, entering it before the guests, taking as a given his or her subjective unity with the rest of those in the theatre, letting the separations between people fade into the background as the sense of unity emerges.
		The conductor who allows his or her personal feelings and reactions to interrupt formality in moments of whimsy or empathy, thus giving a human face to the collective awareness, will summon a corresponding personal presence from performers and audience members.
		When the conductor draws attention to himself or herself, it should be to concentrate audience attention and then give it away, by focusing on someone else or something else, such as the teller, the actors, or an invitation to the audience to respond with thoughts or offers.

	Cable Science
		An important note: this is true whether the conductor is a single solid-core or a stranded conductor of the same conductive mass or DC resistance.
		Although the conductors are subject to flux linkage because of proximity, they have the greater frequency linearity that goes with a smaller diameter.
		This is due to the inductance being dependent on the diameter (or shape) of the conductors and the configuration of the conductors within the cable.

		This conductor could be stranded or solid, but even if you assume the best case for the stranded conductor, i.e.: that it had no oxidation between the strands, then the conductor whether stranded or solid will have the same impedance vs. frequency curve for a given diameter and mass.
		For any conductor with a uniform diameter or uniform thickness, there will be more coupling or linkage of electromagnetic flux at the center of the conductor as compared to the surface.
		The conductor can be compared to a series inductor: the high frequencies are attenuated more and more as the diameter or thickness of the conductor increases and as frequency increases also.

	Magnet and conductor
		The most straightforward would be to encircle the magnet with a conductor; that is, a wire with free charges in it that would be set in motion by the electric field to generate a measurable electric current.
		The conductor surrounding the magnet at rest would show no current; the conductor moving with the moving magnet would show a current and reveal its absolute motion.
		Since the charges of the moving conductor are themselves moved through the magnetic field, that field also exerts a force on them and produces a current.

	Static Electric Sparks and Lightning - School for Champions: Succeed in Physical Science
		The reason is that sparks need conductors, so that the electrons can freely move about and gather enough charges together to be able to jump from one material to another.
		When a conductor—like a metal rod—is brought near a charged non-conductor, the free electrons in the conductor will move to one end or the other of the rod, depending on whether the non-conductor surface is positive or negative.
		When the conductor is brought into contact with the non-conductor, the electrical charges on the surface of the non-conductor are "sucked" into the conductor.

		The Comas provide a masterpiece in their third album "Conductor." Though it's reminiscent of the Shins and Modest Mouse, the Comas prove that they are the only ones on their private planet.
		The DVD is labeled as Conductor: The Movie, possibly indicating that this is a concept album, but the movie doesn't really seem to have a point except to serve as a visual while you listen to the album.
		What it boils down to is that Conductor is a great CD to relax to or have playing in the background, but The Comas fell into the inconsistency trap with this album and it kept the band from making something epic.

	Science@Berkeley Lab: Slicing X-Rays by the Millionths of a Billionth of a Second
		At the atomic scale — the making or breaking of chemical bonds or the transition of a system from one phase to another — changes can take place in a few hundred femtoseconds or less (a femtosecond is one millionth of a billionth of a second).
		Robert Schoenlein (inset), a physicist with Berkeley Lab's Materials Sciences Division, leads the ultrafast spectroscopy research group that is pioneering the use of femtosecond x-rays produced at the Advanced Light Source.
		The ability of vanadium dioxide, a nonmagnetic semiconductor, to change from a transparent insulator to a reflective conductor was first reported back in 1959, but the speed at which the phase transition takes place was only recently clocked by Cavalleri and Matteo Rini, another member of Schoenlein's group.

	electric fields and conductors
		Because the text book then goes on with an example about a positive charge within the conductor, and how the lines from that positive charge would end on the negative charges on the inner surface of the conductor (this is induced) and therefore a postiive charge would be on the outter surface of the conductor.
		Howeever if there are charges within the conductor, then a field would radiate from that charge, and induce charges on the metal of the conductor, and the conductor would also create a electric field.
		Excess charge may accumulate in the conductor, but since like charges repel, the charges in a conductor accumulate at the surface, which brings us back to the situation of a hollow sphere with a surface charge.
