A fundamental goal of physics is to explain the broadest range of phenomena with the fewest underlying principles. Remarkably ...

Researchers show that Cartan's First Structure Equation, which relates to edge and screw dislocations in crystal lattices, can be recast in the same form as a basic mathematical formula that governs ...

Researchers show that Cartan's First Structure Equation links crystal defects to the same mathematical rules governing ...

These fields are all around us, even if you never see them. Earth's iron-rich core, for example, generates a powerful magnetic field that surrounds the planet. Your own brain also emits tiny ...
