Right-Hand Screw Rule
In physics, the right-hand rule is a general mnemonic for understanding notation conventions for vectors in 3 dimensions. It was invented for use in electromagnetism through British physicist John Ambrose Fleming within the late 19th century. While choosing three vectors which must be at right angles to each other, there are two distinct solutions, so while expressing this idea in mathematics, one must erase the ambiguity of that solution is meant.
