Gawker.tv has clips of Oprah audience members doing group process after Jay Leno’s visit to O’s show. WARNING: Watching this has basically ruined/made my day. It has sent me into paroxysms of stupidity, which are kind of like hate-sex orgasms, only they come out kind of sideways, and share certain fundamental attributes with the concept of “negative infinity.” No Harold Bloom for at least an hour after Oprah audience share-time, or you will cramp up and drown like a swimmer with a gutfull of Chinese food. Also, what is negative infinity, exactly? Dr. Achilles at the Math Forum, take it away-

>I would also like a real world example of negative infinity that I
>can use to explain it to my daughter.

Regarding this question, I don’t think I can help because I am at a loss to come up with an example of negative numbers or of positive infinity which would work for a 4-year-old (and I can’t even come up with an example of negative infinity for anyone, offhand.

Best wishes for you and your child in working through tough math concepts.

Oh, well. It was worth a try.
