Re: [math-fun] Simple model of Earth magnetic field, which sounded promising for a little while

Also, I think it would be interesting if anybody could figure out how to build a tabletop experiment which is basically a scale model of the Earth's core. See, I do not believe computers can simulate fluid turbulence in a manner I would believe. But if an actual fluid could be made, then just observe what happens, that I might believe. Difficulties: how to make "gravity"? How to make "internal heat"? And how to choose the right ingredients so that the scaling relationships yield a valid "simulated Earth"? Probably cannot be done?
