I don't think this is really an accurate way of thinking about them. Yes, they can be mapped to a 2d plane, so you can represent them with their two real-numbered coordinates along the real and imaginary axes, but certain operations with them (eg. multiplication) can be done easily with complex numbers but are not obvious how to carry out with just grid points. (3,4) * (5,6) isn't well-defined, but (3+4i) * (5+6i) is.
Imaginary numbers probably, they're useful for a lot of stuff in math and even physics (I've heard turbulent flow calculations can use them?) but they seem useless at first
I accept it; I enjoy most types of meat. But the fact that you can survive without meat makes it optional, which is relevant to the debate we were having about the morality of killing/harming animals for different purposes.
Yeah, it's harder for sure. But what I'm saying is that not everyone needs to kill to eat-- if you can afford it and have some time to plan meals, it isn't a "necessary evil". I'd argue it's still more moral to kill for food than for entertainment, of course.
You have to eat, but you don't have to eat meat. It's just as optional as creating art that involves animal abuse. (Not a vegan, just interested in this topic).
Man, that's a sweet ass-car.
