rjshae Posted December 22, 2021 Share Posted December 22, 2021 Imaginary numbers could be needed to describe reality, new studies find Quote By a relatively simple experiment, they show that if quantum mechanics is correct, imaginary numbers are a necessary part of the mathematics of our universe. 1 "It has just been discovered that research causes cancer in rats."

InsaneCommander Posted December 22, 2021 Share Posted December 22, 2021 (edited) 17 minutes ago, rjshae said: Imaginary numbers could be needed to describe reality, new studies find No surprise for me. The way I see it, imaginary numbers are simply a way to describe two sets of numbers that are related to each other. Time and frequency for time series ("i" appears in the Fourier transform) or position and momentum in Quantum Mechanics, for example. The momentum operator is "i d/dx" and Heisenberg's uncertainty principle shows that position and momentum affect each other, you can't have much precision in one without losing it for the other. Thinking imaginary numbers are bizarre is not much different than thinking negative numbers shouldn't exist just because you can't have "minus three apples" for example. It's just a way to describe numbers in a specific situation, like when you lose three apples, for example. It just happens that imaginary numbers are perpendicular, so in order to get to them you need to "move" half the way you do when you wanna get negative numbers, so i*i=-1 and i is the square root of -1.

It made perfect sense during electronics classes in Uni. The only way you could really design filters and work with frequencies. I still balk at Fourier Transformations. I effin hated that last bit. “He who joyfully marches to music in rank and file has already earned my contempt.

rjshae Posted December 22, 2021 Share Posted December 22, 2021 Imaginary numbers are used mathematically to describe two dimensions with a single expression. Maybe it's telling us there's a quantum dimension of some sort, like two-dimensional time? "It has just been discovered that research causes cancer in rats."
