A third degree surface and a touching sphere
My argument was wrong. It only works only for $a > (2/5)^{1/3}$, where the curvature is monotonic. |

Which has curvature $< 1$, while the circle of radius $\frac{\sqrt 3}{2}$ has curvature $> 1$. And we are done. |

The closest points to $(1,1,1)$ on $xyz=1$ are of the form $(a,1/\sqrt a,1/\sqrt a)$. So, it suffices to check this curve. |
