comment Where's the error in this $2=1$ fake proof?
We assume $x\neq y$? I didn't get it. With Bryan's answer, I've figured that $x^2-y^2=0$ and $xy-y^2=0$ and it would end as $0=0$.

comment How to plot biconditional graphs?
Amy, can you help me with one more thing? There's also an exercise with or instead of and. I'm thinking that it's plot is like a big plus sign. Is this correct?

@DonAntonio Calm down and just catechize him by pressing the edit button. May the spirit of Oiler be with you, brother.

comment The way into logic, Gödel and Turing
Yay! Notes by Peter Smith! I'll download and read too. Herr Peter is damn pro. You should also cite your Introduction to Gödel Theorems, Herr Peter.

comment Why don't we include $\pm\infty$ in $\mathbb R$?
@nik It may be a naive question but: What's the problem in losing associativity?

comment Which book to read on quantum-related mathematics
Recently I watched the "Big Bang Theory" and decided to google about quantum mechanics. - Yay! you're strange like me, I write almost all the references and search about them.

comment CINEMA : Mathematicians
BTW, I opened MSE with a question in mind, the first question was this one, my mind automatically started playing: You are, a cinema, I could watch you forever... - Now I forgot the question! Damn!
