> I argue that they can’t. In the physical world, continuous quantities (be they voltages or the parameters defining quantum-mechanical wave functions) can be neither measured nor manipulated exactly. That is, no continuously variable quantity can be made to have an exact value, including zero. To a mathematician, this might sound absurd, but this is the unquestionable reality of the world we live in, as any engineer knows. Wasn't this problem addressed just recently? https://www.unibas.ch/en/News-Events/News/Uni-Research/The-geometry-of-an-electron-determined-for-the-first-time.html https://www.unibas.ch/en/News-Events/News/Uni-Research/The-g...
