Hey!

If you can run a household, and a budget, and a buch of kids, you've got more guts (and integrity!) that 90% of the college-undereducated news-media "guru's" outthere.

Don't sell yourself short, but don't stop learning either.

Just 'cause we use math doesn't mean we've explained something (well-enough for somebody else) to understand. If it isn't clear, WE (not you) have to do a better job explaining it.

(Our mid-term test will follow in ten minutes, unless there are further questions from the class....)

I just don't follow the 600,000 number as the presumed interval between eruptions. 2,000,000 - 1,300,000 = 700,000; 1,300,00 - 640,000 = 660,000 years. This produces an average interval of 680,000 years between the last 3 eruptions. If the average is used then there's still 40,000 years before it blows. If the last interval is used then there's 20,000 years left. However, if the rate of interval decrease is applied then it should have blown 20,000 years ago (at 620,000 years).

I guess this is why we pay scientists the big bucks, so they can propose some arbitrary number and say "in the final analysis we really don't know". So we're left with prophesy, numerology, tea leaves and the Weekly World News. Maybe Bat Boy can join the USGS and figure this all out.

Your words to Ann Archy - true.

Housewifery is not rocket science...more like POCKET science....but thanks for the high five.
