booze, sun, and philosophy

ok, so it was gonna be "booze, drugs, and philosophy", but the druggiest it got was tylenol extra strength. oh, and there was pot.
went camping this may long weekend, same bat-place as last year, but in my fuzzy recollections there was a lake, not a river. well, this year it was a river :)
the boyz improved on their last year's hot tub design, and instead of digging a hole in the ground and lining it with a tarp they just bought a ginormous inflatamable pool. and used a bigger pipe to make the heating coil with. but only one pump. there was some fancy hydraulics in the plans, but i dont rem why it ultimately wouldnt work, or what the hell it was to actually do in the first place, although it kinda looked like they wanted to suck the water directly out of the river thru these pipes instead of using buckets. or actually just big coolers, or bins of some sort.
by evening the thing got hot enough that it was still comfortable when it started to rain. when it started getting colder somebody brought a tarp and we just pulled it over ourselves and the pool. it was awrite :)
oh the fond memories - passing the bottle of vodka around, followed by the chaser cup... being slammed into the pool from behind and hurting some chix legs with my jaw. i think nothing happened to me because i was so drunk :) and i got back at the dork that pushed me in by dragging him into the pool when he got near enough :)
nobody got my new favourite joke of "whats blue and doesnt fit anymore?" though... :(
and nobody liked my tunage, like "rubber bullets", by 10cc apparently.
oh well.
had some cool wondrous moments. i hatched a theory on my buddy that sounded something like "a high incidence of stupid but good looking chix in a society may be advantageous to said society by way of lowering the average level of sexual frustration and aggression of intelligent but aggressive males, thereby promoting cooperation as opposed to competition." sounds chauvinistic, but it was funny at the time :)
then i really got to wunderin', and started wondering why the earth's magnetic polarity keeps shifting and even reversing. i believe that the earth's overall polarity is the sum effect of the polarities of all the magnetic particles in earth, but my questions was: what makes all those particles face the way they face? what about other planets' magnetic fields - are they aligned with ours? or is every body independent? i guess i should look for the answers online...
another thunk i had was "why are there so many relatively small rocks in the world?" when big earthquakes happen, do they make the bedrock brake into all these small crumbs? or are there first huge rocks and then the elements break them down over eons? i start feeling impatient when i consider that to be the case. that would just take too long.
