Electricity without friction: the physics of zero resistance
In short: Imagine a train that never stops once it starts moving. This video explains how certain materials achieve this state of perfect conduction, moving from basic analogies to the quantum mechanics that power modern medicine and high-speed travel.
Superconductivity occurs when materials lose all electrical resistance once cooled below a specific critical temperature. This allows an electric current to flow indefinitely without energy loss. The phenomenon was first discovered in 1911 by Kamerlingh Onnes, who observed it in mercury.
The underlying physics is explained by the BCS theory, which describes how electrons form 'Cooper pairs' through quantum mechanics. While early superconductors required extreme cooling, modern high-temperature superconductors, such as copper oxides, can function at relatively warmer temperatures. These properties are essential for technologies like MRI machines, maglev trains, and the Large Hadron Collider.
