Evaluating magnitudes of non-algebraic numbers

[espen180]

Just like it is possible to show that e^\pi > \pi^e, is it possible to show that

\sqrt{2}^{\sqrt{2}} > \frac{1+\sqrt{5}}{2}

or

\sqrt{2}^{\sqrt{2}} < \sqrt{3}

Since all these numbers are well defined, it is possible, although at times it might require a little work.
