Listening to the talk about complex numbers, my hand suddenly stopped.A complex number is expressed asz = a + ib.a is the ...

Yes, those of us who studied mathematics and physics after high school are familiar with the values $${i = \sqrt{-1}}$$ and ...

To a nonmathematician, having the letter “i” represent a number that does not quite exist and is “imaginary” can be hard to wrap your head around. If you open your mind to this way of thinking, ...

Here’s what you’ll learn when you read this story: A team of German physicists has built a fully working version of quantum mechanics that uses only real numbers. Complex numbers, built from a ...

All non-trivial zeros of the zeta function have real part one-half. Unfortunately, all those negative even numbers are trivial zeros. So … where are these non-trivial ones? To answer that, I must take ...

Imaginary numbers might seem like unicorns and goblins — interesting but irrelevant to reality. But for describing matter at its roots, imaginary numbers turn out to be essential. They seem to be ...

In this math tutorial, I will show you how to add and subtract complex numbers. You will learn the steps in adding rational complex numbers and rational expressions with imaginary. Like polynomials, ...
