comment Proof of Hasse's principle for quadratic equations
@JyrkiLahtonen am I correct in saying that the easier direction is proving when the real solutions and p-adic solutions exist, then the rational solution must exist?

comment If $f$ is entire and $f^{(5)}$ is bounded in $\mathbb{C}$ then $f$ is a polynomial of degree at most 5
Yes, that makes sense. Thanks again.

comment If $f$ is entire and $f^{(5)}$ is bounded in $\mathbb{C}$ then $f$ is a polynomial of degree at most 5
Thank you for the help. I understand intuitively why $f^{(5)}$ being constant implies that $f$ is a polynomial of degree at most 5, but how would I best prove this?

@SandeepSilwal I know about the Cantor Set. I know that the elements in the Cantor Set can be written in a ternary expansion, but how does that relate to this?
