Superconductivity Discovered: Zero Resistance, Infinite Possibility
Heike Kamerlingh Onnes watched electrical resistance vanish completely in mercury on April 8, 1911, proving that matter could conduct electricity without any energy loss. This discovery birthed a new quantum state where electric currents flow indefinitely and magnetic fields flee the material's interior, fundamentally altering our understanding of physics beyond classical limits. The phenomenon later enabled high-temperature superconductors in 1986, opening pathways for technologies that operate efficiently at temperatures far warmer than absolute zero.
