comment A Different Type of Knights and Knaves
This is exactly the same as the standard Knight/Knave puzzle involving two doors. The proposition "the left door is the correct one" is replaced by "someone has proven GC", that's all.

comment Hashing With Chaining Collision
Could you be a little more detailed about how the hashing works? The objects are numbers $1...1000$, the keys are numbers $0...9$, but what does "two keys map two elements to one index" mean?

comment Finding a cubic polynomial whose splitting field over $\mathbb{Q}$ equals $\mathbb{Q}(a)$ if $a$ is any of its roots
What about $x^3-1$? Its splitting field is generated by a single root, but that doesn't quite fit your question because you have to be careful which root you choose.

comment Why is $0/0$ not $\Bbb R$?
What would it help to say it's equal to $\mathbb R$? What problems would be easier to solve or have more elegant solutions? What theorems would be simplified?

comment Which book is appropriate for a Chemistry student that needs to learn basics about integrals?
I think the wording "non-mathematical student" suggests something like an art or history student, so I took the liberty of editing your title.

comment What is the relationship between dim(Im(T)) and dim(Im(T^2))
@Dansmith If by "from $V$ to $V$" you mean a surjective map from $V$ to $V$, then you're correct.
