Sliding Down Earth's Spacetime Curve

"The air around you is filled with floating atoms, sliding down the Earth's spacetime curve. Atoms first assembled in the cores of long-dead stars. Atoms within you, everywhere, disintegrating in radioactive decays. Beneath your feet, the floor - whose electrons refuse to let yours pass, thus making you able to stand and walk and run. Earth, your planet, a lump of matter made out of the three quantum fields known to mankind, held together by gravity, the so-called fourth force (even though it isn't a force), floating within and through spacetime."

- Christophe Galfard (1976 - )
The Universe in Your Hand

Postscript. This height of this lovely waterfall - Rocky Brooks Falls near Dosewallips State Park, WA - is hard to judge from the picture alone, but it is among the Olympic Peninsula's tallest at about 230 ft! Rocky Brooks falls is also embarrassingly easy to get to: a short 4 mile journey by car on a paved road from the main highway that runs up the Hood Canal, and then (the truly embarrassingly easy part) a 200 yard (!) hike - though "hike" is not the best word: you'll hardly have time to take more than a few breaths before coming to the falls, and can keep the munchies and extra water back at the car. Well, maybe that last part is a bit premature... the falls are so extraordinary to experience in person - the sound, the smell, the subtle mist, the surrounding bird song, and the gentle burbling stream that both greets each expectant visitor and says farewell - that one is well advised to anticipate a longer-than-casual-length stay. Over the course of my family's two weeks on the Peninsula, I took four trips to this falls - the shortest of which lasted no less than 3 hours - and each time spent far more time just sitting and communing with its tender rhythms than prowling around with tripod and camera looking for compositions. A reminder that there are special places that - with "good motivation and appropriate merit" (ref: a blog entry I posted about a week ago) - palpably compel you to stop whatever you're doing and just ... be.
