Torque is in this direction; spin angular momentum's in this direction.

力是这个方向，旋转角动量是这个方向。

This causes the applied force to act as a torque, which therefore gives the ball a spin.

这将导致作用力产生一个扭矩，使球旋转。

So the torque is persuading the spin angular momentum to change.

所以力是使得旋转的角动量,改变的理由。

During a recent LSI technology event EverSpin was showcasing its recently announced spin-torque MRAM memory that provides a non-volatile replacement for DRAM.

Grandis makes a non-NAND flash solid state storage technology called spin-transfer torque RAM (STT-RAM) that stores information via the direction of magnetization in a spin-polarized electron current.

If you're a frequent reader you're surely well aware of the potential of spin torque transfer memory, or STT-MRAM, and how spin-polarized magnetic currents (and the electrons they love to caress) might hold the potential to revolutionize storage as we know it.
