This is called Hale's law. "The magnetic field from active regions makes its way toward the poles and eventually causes the reversal," solar physicist Todd Hoeksema, director of the Wilcox Solar ...

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 ...
