Heinz London

Heinz London was a notable physicist known for his work on superconductivity, which is the phenomenon where certain materials conduct electricity without resistance at very low temperatures. He, along with his brother Fritz London, developed key theories that explained how magnetic fields interact with superconductors, leading to the understanding of the Meissner effect—where a superconductor expels magnetic fields. This foundational research has paved the way for advancements in technology, including magnetic levitation and improved electrical systems, highlighting the unique and counterintuitive behaviors of materials in low-temperature physics.
