- Since my first posting made a less-than-resounding thud, like the
- plodding pedantic humourless engineer I am, I figured I'd try again
- (and since I have a couple of minutes to kill before the next run ends).
-
- Several people have complained lately about the subject matter
- around this neck of the woods, so I wonder if some of those people
- will oblige me by posting what they believe to be compelling
- mysteries or pressing problems in their particular field.
-
- I have already posited that I believed the
- a) galactic rotation curves
- and
- b) cavitation sonoluminescence
- were pretty interesting indications that maybe we were thinking about
- said problem(s) incorrectly. Now a couple of people did take me
- to task about problem a) not being that much of a problem. However,
- since it's my list, and visceral examination counts for as much as
- anything when one is speculating about unsolved problems, I'll leave it.
-
- There are others,
- c) the long-time stability of the solar system
- that several of us discussed earlier. Biology tends to tell us
- that the solar system (or at least the earth's orbit) has been stable
- for long lengths of time. Calculations and perturbation theory tend
- to tell us differently. Of course, I don't believe the calculations,
- but what do I know? Opinions are very cheap, so spill them all over the
- place. Where is our fundamental misunderstanding? Where are others?
- d) the solar neutrino 'problem'. Is it a problem? Do we believe
- the calculations. Why do no two experiments seem to tell us the same
- thing? Is something being left out of the 'standard model' of the
- sun? How much *is* gallium chloride by the ton?
- e) why does the Hubble 'constant' float all over the place. It
- almost seems like one could select a value at random and find very
- good support for that value in astrophysical observations.
-
- I'll save the rest of my rather voluminous mental 'list'.
-
- Now surely many of the people reading here have a physical problem that is
- compelling enough to discuss; compelling enough to wonder aloud what the
- ultimate solution might be. Surely large numbers of us have a list
- of compelling physical problems that we are dying to share with the
- rest of the sci.physics world?
-
- Now scout's honor, I personally promise not to comment in any but a very
- very positive manner if anyone wants to bring up anything, anything
- at all (even chaos). I cannot guarantee anyone else, but if you stick
- your neck out, I promise that the bleeding will ultimately be minimal.
- And you'll have the side benefit of greatly increased typing speed
- like the rest of us loudmouths.
-
- I like a bit of wonder and mystery in the universe, it gets so boring
- when a common attitude is that everything is fundamentally solved.
- And actually, I'm just looking for things to add to *my* list.
