The measurement of a quantum state poses a unique challenge for experimentalists. Recently, the technique of ‘direct measurement’ was proposed for characterizing a quantum state in situ through ...

Angular displacement is a crucial concept in physics, particularly when studying the motion of rotating objects and circular motion. It is defined as the angle through which an object in circular ...

Last month, we saw how you can use vectors to define complex circuits and determine current. This month, we'll show you how to use vector diagrams and some simple math to calculate neutral currents in ...
