James got his hands on a type 2 superconductor. After chilling it with liquid nitrogen the fun begins. He places it on a magnet and it floats above the superconductor. Liikwise if the magnet is above the superconductor or the magnet is spinning around a magnetic track. The magnet and superconductor defy gravity but they don't attract or repel each other. They lock. The explanation is quantum.

SUnknownCan You Make Magnets Orbit Each Other?

Sat, May 08, 2021

Thecurving dipole nature of magnetic fields makes it difficult for magnets to orbit each other. So James arranges two magnets to produce a region where the magnetic field is relatively flat and has better success. But will the orbit be stable?

SUnknownTessellation Is Easier Than You Think

Mon, Nov 08, 2021

Tesselation involves tiling a surface with one, or more, shapes. Tesselation has a storied history and it's now know that all triangles and quadrilaterals will tessellate if you know their placement trick. But there seems to be a limited number of pentagon and hexagon and no larger polygons that tessellate.

SUnknownWhat Happens When a Liquid Turns Supercritical?

Mon, Feb 14, 2022

James displays an ampule of supercritical xenon pressurized to sixty atmospheres. On cooling it condenses to a liquid. But when warmed it doesn't boil. The liquid an gas simply merge.

SUnknownNewton's Cradle Doesn't Work the Way You Think

Fri, Dec 20, 2024

Newton's Cradle looks so simple. But physicists are still working on modeling exactly what's going on. There's more to it than just conservation of momentum or even energy. There's a pressure way that determines which balls move the most.
