I have been looking for information on this. I was watching some amish documentary which mentioned that if you did something bad within the community that you could be shunned for a period of time, I was thinking that this would be great!
I'd love to be shunned and just to mathematics all of the time. Grow a beard. Never bathe. Drink beer.
Oh yeah, back on topic.
Has anyone ever heard of a famous Amish mathematician? I couldn't find anything online and figured people who studied math extensively may have come across a name somewhere.
