Going beyond the Golden Ratio. I show that for the same reason that the golden ratio, $\phi=1.6180334..$, can be considered the most irrational number, that $1+\sqrt {2}$ can be considered the 2nd most irrational number, and indeed why $ (9+\sqrt {221})/10$ can be considered the 3rd most irrational number.
