swansont Posted March 5 Share Posted March 5 “Yes, everything in physics is completely made up – that’s the whole point” https://www.sciencefocus.com/news/everything-physics-made-up/ Is it ever true, then, to say that an electron is ‘real’ when it’s in motion? If we believe that electrons are real things, have we just made up the wavefunction to make the math work out? Absolutely – that was, in fact, the whole point. We couldn’t get the equations to work if the electron was a solid, isolated particle, so we made up something that wasn’t, and then the numbers started making sense. … physics isn’t built around ultimate truth, but rather the constant production and refinement of mathematical approximations. It’s not just because we’ll never have perfect precision in our observations. It’s that, fundamentally, the entire point of physics is to create a model universe in math - a set of equations that remain true when we plug in numbers from observations of physical phenomena.
