Superconductivity — Graph

What later discovery did Kamerlingh Onnes make using the same cryogenic apparatus that liquefied helium?

What did Kamerlingh Onnes observe happen to mercury's electrical resistance at 4.2 Kelvin?
Why was the abruptness of the resistance drop, rather than a gradual decline, so surprising to Onnes?
How did Bardeen, Cooper, and Schrieffer eventually explain superconductivity nearly half a century after its discovery?
What modern technologies, like MRI scanners, depend on the superconductivity Onnes first observed in mercury?

What happened to mercury's electrical resistance as it approached absolute zero?
Why did the Nobel committee cite the helium liquefaction rather than superconductivity itself?
What modern technologies depend on materials cooled near absolute zero?

Why do electrons in a superconductor pair up instead of repelling each other?
What lets a Cooper pair glide through a metal without scattering and losing energy?
Why did it take nearly half a century after superconductivity was first observed to explain how it worked?

What did Brian Josephson predict would happen to current flowing between two superconductors separated by a thin insulating barrier?

Why did the conventional wisdom in 1986 hold that ceramics were an unpromising place to look for superconductivity?
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 other laboratories initially refuse to believe the 1986 superconductivity result and rerun the experiment themselves?
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?
Why had physicists assumed superconductivity was impossible above about 30 Kelvin before 1986?
Why did the Nobel committee award the prize less than a year after the original paper?
What technologies did the discovery of high-temperature superconductors open up for future research?

How does helium-3 achieve superfluidity differently from helium-4?
Why did the pairing mechanism in helium-3 require theorists to extend existing frameworks of quantum order?

What distinguishes a type-II superconductor from the type first discovered in 1911?
Why did Abrikosov and Ginzburg's theory of quantised magnetic filaments make high-field superconducting magnets possible?
Why did the Nobel Committee wait roughly fifty years to recognize this work?

What chain of events, starting with a faulty electrical connection, caused the LHC to shut down just nine days after its first beam?

How did Clarke, Devoret, and Martinis show that a macroscopic superconducting circuit could tunnel through an energy barrier?
