Meh.
„A complex number is nothing but two real numbers,“ Barrios Hita said. His team essentially built a bookkeeping system that tracks those two real numbers separately, instead of combining them into one complex number.
For decades, there’s been an intense debate over whether imaginary numbers are a fundamental property of our physical reality or just an incredibly convenient mathematical shorthand we use because the math is cleaner. If they successfully modeled quantum mechanics using strictly real numbers, it strongly suggests complex numbers might just be a tool rather than a physical law
Imaginary numbers are just an easy way to do vector math.
Sounds like convoluted shit someone is gonna have to use a metaphor to explain to me.
Does this have any actual implications?
I mean, good for them, but that math must be *hideous*. We use imaginary numbers primarily because they simplify the math.
