An expermental and theoretical study has been made of the aerodynamic drag torque on a sphere rotating in a rarefied gas. The drag torque on a magnetically suspended polished steel sphere rotating in ...

For nearly a century, scientists have been scratching their heads and reworking theories about a seemingly ho-hum problem: How does nature organize electrons, cells or other particles onto the surface ...
