I'm a Professor at UC Irvine, but spent most of my career at Brandeis. My research areas: Differential Topology, Transformation Groups, and Global Analysis. Recently I developed a math visualization program, 3D-XplorMath, freely available at http://3D-XplorMath.org) and a companion website, the Virtual Math Museum at http://VirtualMathMuseum.org. Last year I co-authored a differential equations text with my son Bob, most of which is downloadable from http://ode-math.com .

Direct proof of irrationality?
Sure, I realized "my" answer (of course it really is NOT original with me) was not exactly what the the OP asked for. However this proof is so completely elementary---even for the final part, you only have to know what a monic polynomial means---that I thought it might appeal to many readers who looked at this question. |

Ye, Andres, thanks, don't know what the problem was but it's fixed now. |
