HOW IT WORKS. "Inside each magnetic flux tube superconductivity is locally destroyed. The superconductor will try to keep the magnetic tubes pinned in weak areas (e.g. grain boundaries). Any spatial movement of the superconductor will cause the flux tubes to move. In order to prevent that the superconductor remains "trapped" in midair." https://lnkd.in/emW6Tsg View in LinkedIn

FLUX TUBES. "Superconductivity and magnetic field [sic] do not like each other. When possible, the superconductor will expel all the magnetic field from inside. This is the Meissner effect. In our case, since the superconductor is extremely thin, the magnetic field does penetrate. However, it does that in discrete quantities (this is quantum physics after all! ) called flux tubes." https://lnkd.in/emW6Tsg View in LinkedIn

SPACEHOUNDS. "Among the many examples of how science fiction and fantasy have inspired real science, an interesting one is the “tractor beam,” first conceived by the chemical engineer and writer Edward E. Smith in the 1930s in his novel Spacehounds of IPC." https://lnkd.in/eYSRjM2 View in LinkedIn

QUANTUM LEVITATION. "Left-handed metamaterials are known to make perfect lenses that image classical electromagnetic fields with higher resolution than the diffraction limit. For optical left-handed metamaterials, this repulsive force of the quantum vacuum may levitate ultra-thin mirrors on, literally, nothing." https://lnkd.in/eCBg2Ha View in LinkedIn
