Questions extracted from the papers in this topic, excluding the curated questions above.
- How did Bardeen, Cooper, and Schrieffer eventually explain superconductivity nearly half a century after its discovery?
- How did Clarke, Devoret, and Martinis show that a macroscopic superconducting circuit could tunnel through an energy barrier?
- How does helium-3 achieve superfluidity differently from helium-4?
- What chain of events, starting with a faulty electrical connection, caused the LHC to shut down just nine days after its first beam?
- What did Brian Josephson predict would happen to current flowing between two superconductors separated by a thin insulating barrier?

- What modern technologies, like MRI scanners, depend on the superconductivity Onnes first observed in mercury?
- What technologies did the discovery of high-temperature superconductors open up for future research?
- What technologies, like lossless power transmission and floating trains, depend on finding higher-temperature superconductors?
- What temperature record did Bednorz and Müller's copper-oxide ceramic break in 1986?
- What transition temperature did Bednorz and Müller find in their barium-lanthanum-copper-oxide ceramic, and how did it compare to the previous record?
- Why did Abrikosov and Ginzburg's theory of quantised magnetic filaments make high-field superconducting magnets possible?
- Why did it take nearly half a century after superconductivity was first observed to explain how it worked?
- Why did other laboratories initially refuse to believe the 1986 superconductivity result and rerun the experiment themselves?
- Why did the Nobel Committee wait roughly fifty years to recognize this work?
- Why did the Nobel committee award the prize less than a year after the original paper?
- Why did the Nobel committee cite the helium liquefaction rather than superconductivity itself?
- Why did the conventional wisdom in 1986 hold that ceramics were an unpromising place to look for superconductivity?
- Why did the pairing mechanism in helium-3 require theorists to extend existing frameworks of quantum order?
- Why do electrons in a superconductor pair up instead of repelling each other?
- Why had physicists assumed superconductivity was impossible above about 30 Kelvin before 1986?
- Why was the abruptness of the resistance drop, rather than a gradual decline, so surprising to Onnes?
