Happy Birthday Inge Lehmann


Recommended Posts

From the Wiki Article.

Inge Lehmann ForMemRS (May 13, 1888 – February 21, 1993) was a Danish seismologist and geophysicist who discovered the Earth's inner core.[2][3] In 1936, she postulated from existing seismic data the existence of an inner core with physical properties distinct from the outer core's and that Earth's core is not a single molten sphere. Seismologists, who had not been able to propose a workable hypothesis for the observation that the P-wavecreated by earthquakes slowed down when it reached certain areas of the inner Earth, quickly accepted her conclusion.

This a a wonderful instance of indirect observation which is an instance of abduction, inferring likely causes of that which is observed. This is what people in the physical sciences do a great deal of the time.

Ordinary people do this too. When you hear a funny sound coming from your car while driving, you go through a set of possible causes and infer a likely or believable cause based on the set of possible causes and some other observations you make and from elimination like varying the speed of the car to eliminate speed dependent causes or verify speed dependent causes.

This is also the basis of Bayesian Estimation in statistics and probability theory.

I was hoping for another answer. I was hoping for your gratitude for helping you fix OL. How convenient a whipping boy is my "browser cache." Now I have to give succor and comfort to my browser since it cannot but read what you have posted. I may even have to get professional help to psychologically save it.

nuts--OL can be a horrible place

Brant, what browser do you use? And which operating system (Windows, Mac ...)?

In case you don't quite know what a browser cache is, and why an existing cache might prevent you from seeing 'new' activity flagged, it is fairly straightforward. When you 'reload' or revisit a page -- in this case the page that shows you 'new' activity -- your browser in certain circumstances returns some page data (like images) that it has kept in its internal memory.

I don't know if this is actually the case, a cache image/state rendering a thread's last entry as 'read' instead of 'unread.' But if it is the case, your problem will be solved once you purge or clear your browser cache.

If the problem is your browser cache, do you know how to clear it out? (maybe you have already done this purge, anomaly vanquished, no problem remaining, but you wanted to have some fun riffing)

He is trying to figure out how to take control of the Ex Machina's soul...

I pretty much got the hang of it. It's Windows/Firefox. Maybe Internet Explorer, but I don't use it very much. I had to bitch-slap Michael after he explained it to make sure he stays in his place respecting The Master, whose giant ego was badly traumatized by an insight not its own.

ergo, nothing is more important than (my [not your]) ego

Too late--to put me in my place.

poster's gone wild--you should read my other stuff today (I mean, you shouldn't)

out of control, eating up the troll
