George Spagna, chair of the physics department at Randolph-Macon College, explains. Stars and planets form in the collapse of huge clouds of interstellar gas and dust. The material in these clouds is ...

When multi-joint reaching movements are made within a rotating reference frame, additional interaction torques are generated in the form of Coriolis forces. Coriolis forces are a function of the cross ...

The viral video of a high school student flipping a water bottle so that it lands straight upright on a table has set the internet ablaze. With the pressure of his peers looking on, Michael Senatore, ...

The UPR-270 Air features best value for wobble and flatness and one can reach high accuracy because of high-precision air bearing. All rotation stages UPR-270 AIR are directly driven by a torque motor ...
