This is the personal blog of Chris Lang. I am a mathematics professor at a regional campus of Indiana University (IU Southeast, in the Louisville, Kentucky metro area north of the Ohio River).
I've turned off comments, mostly because it was a chore to deal with spam. If there is something you would like to say, please email me; if appropriate, I would be glad to add your comments to a post of mine.
I should mention that I'm not above going back and editing my posts. If I make substantive changes on an important topic, I'll mention these.
If anyone has any concerns about this website or any comment or post on it, please contact me. I can be reached through the university.
My old blog is archived at my site www.wclang.net.
