Precession Intuitively Explained

Formal explanations of the dynamics of free and heavy Handlebar Sensor Cable tops are considered to be known for centuries.However, intuitive understanding of their unexpected behavior is still a challenge.In this paper, we present elementary force based explanations of precession of heavy symmetric tops, derived in inertial and non-inertial refere

Squashing and supersymmetry enhancement in three dimensions

We consider mass-deformed theories with ${cal N}geq2$ supersymmetry on round and squashed three-spheres.By embedding the supersymmetric backgrounds in extended supergravity we show that at special values of mass deformations Toys the supersymmetry is enhanced on the squashed spheres.When the $3d$ partition function can be obtained by a limit of a $
