FTA: "Evan Zalys-Geller, a condensed matter physicist at the Massachusetts Institute of Technology in Cambridge, says that the resistance measurement wasn’t sensitive enough to distinguish between a zero resistance superconductor or a low-resistance metal like copper."
I have little knowledge of the field, but as an EE, I would have thought that making sure that you are actually able to measure the effect you are trying to prove would be step zero in an experimental setup, no?
- distortionfield 3y agoFrom what in understood, the sharp drop in resistivity was consistent enough to mark as the change to superconduction
- dekhn 3y agoPeople overestimate their ability to run high quality scientific experiments. I think a perfect example was the claim of faster than light neutrinos (https://en.wikipedia.org/wiki/Faster-than-light_neutrino_anomaly https://en.wikipedia.org/wiki/Faster-than-light_neutrino_ano...). it was experimental error. CERN sent a team of smart EE/physics folks to debug it quickly. This is consistent with my estimate that 90% of all physics labs aren't capable of building, running, and interpreting state-of-the-art scientific measurement and discovery.
