Thanks -- I'm familiar with transcendental numbers, but I'm still trying to

understand the class you referred to as algebraic numbers. I googled that

phrase, and got oogled by things I'm still trying to wrap my mind around. I

once encountered the question of whether or not 0.101001000100001000001 ...

would be an irrational number, and until now, I had forgotten about it. Could I

take it correctly from your reference to the 'Liouville proof' that the above

would indeed be irrational? It doesn't technically have the standard

repetition, right? If it was rational, I'd love to see the fraction. It's been

too long since I studied all the types of infinite series in calculus.
