SPACE, TIME AND FIREWOOD
Folks who don't heat with firewood can't really appreciate all that goes into that bit of sunshine in your winter wood stove, they might think maybe it's easy just because it's free (at least mostly free, the way I do it), but there are other burdens that come with the erratic supply of gleaned firewood such as I use. There's really no need to mention here the sectioning and hauling and splitting and hauling and stacking and hauling and burning and hauling and hauling and hauling, but I already did so it's too late.
Take 2: Say you've got four or five cords of firewood crowding out there in various locations around your house, wood from various periods of time in the past couple years, some of it stoveready, some not, but you've run out of stacking space and have just been given access to a whole new multicord bunch of bigwood to be split and stacked so it will dry by the time you need it two or three winters from now, so you've got to put it somewhere but you can't stack new green wood on top of fully or nearly ready wood, so you've got to walk around, analyze your stacks, ponder the weather and your wood supply, juggling disparate concepts sort of like Einstein used to do with various other aspects of the universe while wandering his theoretical woodlot.
With these sylvan symbols as well, like Albert you've got to somehow bend time and space by combining a couple of nearly ready pieces of embodied light, i.e., photons+alpha = wood, into one taller stack, thereby clearing a place for the new incoming atomic structures. Then when winter comes, in the heart of your stove you unleash the energy of those atoms in the welcome form of heat while freeing up some space outside, thereby establishing a direct link between time, space and firewood, but right now you have to match the mix of new and old.
Fortunately, last year you began to denote all this data in numerical symbols on the end face of one piece of wood at the top of each stack, but unfortunately as the universe would have it the newest wood always seeks the top of the stack, so to get at the older wood you have to go to the bottom, by for example turning the whole stack over, which is cosmically impractical (Albert, working in complete abstraction, had it easier in this regard), and practicality is what we're talking about here, so this approach needs work. Al's work led to atomic fissioning and nuclear power, which here in Japan has a bigly negative historic reputation but is still used in winter to power electric heaters, blu-rays, plasma tvs and game consoles, among other things.
This is a universe, after all.
