aOne example is the Japanese conductor of the Boston Pops Orchestra – he waves his shaggy mane from one side to another, peeping out from under the heavy bangs half covering his eyes. All conductors tend to have long leonine manes, but covering the vision and hiding behind it is not quit...

Thanks for the overview on conductors!FAQ: Definition of Conductor: What is a Conductor? What is a conductor? A conductor is a material or substance that allows the flow of electricity or heat through it. What are the properties of a good conductor?
it's really about sorting it into stuff like, this recording is from the market, this one is from the bus station. Or when I record people directly in interviews, it's organized into things like “conductors”, “hawkers”, “street sellers”, whatever. The main thing [for the Ojuelegba...
Spark gap ignitersare used to create a controlled static discharge. Opposite charges build up on each of the conductors until their attraction is so great charges can flow through the air. One of the most dramatic examples of static discharge islightning. When a cloud system gathers enough ch...
