on re-reading, it doesn't make the point I intended. I sound even more egotistical than I am, and just as detail obsessed.

My point should have been that checking for posts, reading, and especially writing on the boards does take time; I probably an hour or so yesterday and a bit less today of relief in between some quite onerous chores that I described in overly great detail in that last post.

But to answer Chris's question, most of my work would be just about as exciting to the people posting here as yesterday's chores; it's programming, finding the data, seeing what very specific theories do or don't fit. So that's why I only throw up some of my own work if it might be of general interest, like tidal correlations or the healing of fault zones. This weekend the question is whether the inner core rotates, but I have not even looked at the evidence, just lined up the files are another round of analysis.

This week I'll finish and send off a paper on a different aspect of core rotation to GRL. Since Chris asked, I'll write a four sentence summary. The French set off seven M6'ish nuclear tests in nearly the same place on a Pacific atoll from 1977 to 1987, and I got the P wave recordings (PKiKP and PKIKP for purists) at the NORSAR array in Europe. The waveforms change gradually over time for the seven explosions, either due to inner core rotation or due to a steady progression of the locations of the explosions. I think it is the former, but can't tell for sure because the locations are a secret. This matches some previous results I (and others) found that the inner core seems to be spinning a few miles a year faster than the mantle. We'll see what the reviewers think.
