Imaginary numbers can be used to find roots of polynomials when some or all of the roots are not real numbers. Imaginary numbers also have enormous usage in physics, where they are used to model light waves, sound waves, and even alternating current in the study of electricity. They are al...
Imaginary numbers are useful for manipulating many of the equations in physics. For our purposes, which will be clearer later, imaginary numbers are very useful for representing both cyclical phenomena and the phase of a wave(s). A complex number is one that contains both real and imaginary ...
But imaginary numbers, and the complex numbers they help define, turn out to be incredibly useful. They have a far-reaching impact in physics, engineering, number theory and geometry. And they are the first step into a world of strange number systems, some of which are being proposed as mo...
Quaternions, which extend imaginary numbers into a further dimension, began to be developed by William Hamilton in Dublin in 1843.───1843年,威廉•汉密尔顿(WilliamHamilton)在都柏林发明了四元数,将虚数扩展到四维空间。 The more science I studied, the more I saw that physics becomes metaphysics ...
In physics, however, the oddness of imaginary numbers was disregarded in favor of their usefulness. For instance, imaginary numbers can be used to describe opposition to changes in current within an electrical circuit. They are also used to model some oscillations, such as those found in grandfat...
number- a concept of quantity involving zero and units; "every number has a unique position in the sequence" complex conjugate- either of two complex numbers whose real parts are identical and whose imaginary parts differ only in sign
