I'm presuming this is old news to you, but what helped me get comfortable with ℂ was learning that it's just the algebraic closure of ℝ.

- bananaflag 8mo agoAnd why would R be "entitled" to an algebraic closure? (I have a math degree, so I don't have any issues with C, but this is the kind of question that would have troubled me in high school.)
- alexey-salmin 8mo agoThe good news is that Q is not really entitled to a closure either.
- srean 8mo agoWhen it doesn't, we yearn for something that will fill the void so that it does. It's like that note you yearn for in a musical piece that the composer seems to avoid. One yearns for a resolution of the tension. Complex numbers offers that resolution.

- seba_dos1 8mo agoWhy would N be entitled to it? We made up negative numbers and more just to have a closure. You just learn about them at an age when you don't question it yet.
