Recently we wrote an email to Keith Moffatt about his news brief on Euler's disk. Our conjecture is Euler's disk behaves as it does due to fermionic wobble. Larger hollow disk subsumes smaller hollow disk which subsumes smaller solid disk. All disks are concentric. Inner two disks have nearly identical masses.
Outer disk is rigid but ideally very small in mass compared two inner two disks.
Inner two disks require some mechanism which allows them to be contrarotated to achieve balance of their angular momenta. Our experiment will help us answer that question. Our disk will not perfectly model a macroscopic boson because contrarotational coherence is partial and our outer disk, depending on its mass ratio to our two inner contrarotating disks, retains partial fermionic affects on our experiment. If you are interested in using this idea, especially to perform our experiment, please contact us at Quantonics . What we want do is to 'shoot' it obliquely into a pool table's edge.
