Superconductivity is a phenomenon that has shaken up the scientific community on numerous occasions throughout the 20th century-even bringing different researchers Nobel Prizes on seven separate occasions. Thanks to these studies, we have high-speed bullet trains, tomography, supercomputers, and the Large Hadron Collider. Furthermore, in New York in 2008, the first superconducting power line in the world was established. Its capacity is 10 times greater than that of conventional copper conductors. So what is special about this phenomenon, and what causes superconductivity?
