This is a ridiculous response. > No one is allowed to fail so nothing is discovered. 2nd para in wiki article: "It [ITER] is an experimental tokamak nuclear fusion reactor" (https://en.wikipedia.org/wiki/ITER https://en.wikipedia.org/wiki/ITER) It is an experiment, it was never expected to have certain outcomes.You don't seem to understand that. > And exactly how is superconductivity so very little understood? That's not what I said. Here "when that tech (superconductivity) was so very little understood" Note: 'was'. Not 'is'. (see edit below) As for the progression in their understanding I'll leave that for a physicist to discuss. You aren't. Edit: see https://en.wikipedia.org/wiki/Superconductivity#High-temperature_superconductivity https://en.wikipedia.org/wiki/Superconductivity#High-tempera... for a list of recent stuff (eg. last 15 years). And stop shouting about how stupid everyone else is.
