WebThe imaginary number arises from asking what the square root of –4 would be. What we’re discovering here is not some deep mystery about the universe. Surely the question is meaningless? If you square a number, whether positive or negative, the answer is positive. So you can’t do the inverse operation if you start with a negative number. WebPhysics uses it. Electrical Engineering often have to use the imaginary unit in their calculations, but it is also used in Robotics. There, to rotate an object through 3 dimensions they even result in using Quaternions (which build on the imaginary unit i). WebMar 3, 2024 · Imaginary numbers, labeled with units of i (where, for instance, (2 i) 2 = -4), gradually became fixtures in the abstract realm of mathematics. For physicists, however, real numbers sufficed to quantify reality.
