Q: What's the difference between a pigeon?
A: None, both legs are the same length, especially the left one.

Also, this is now a spiderman thread.

If we take x^2 + i = 0 in the complex plane, then the roots are x = +- sqrt(-i) which are not in the complex plane, however the fundamental theorem of algebra states that the complex plane is algebraically closed, how does this work?

Mom always told me to keep away from rings of characteristic 2.

Joke is on you, I am siding with the CS monomaniac on this one. My area of research precisely requires to find encoding of mathematical objects that are better-behaved computationally w.r.t. rewriting systems defined by generators.

The funny thing is that the encoding of the structure per se is fairly irrelevant, what matters more is how the morphisms over that structure behave. Elements of any countable set can be coded by a fucking array of numbers.

Talk maths.
