What appear to be the most valuable aspects of the theoretical physics we have are the mathematical descriptions which enable us to predict events. These equations are, we would argue, the only realities we can be certain of in physics; any other ways we have of thinking about the situation are visual aids or mnemonics which make it easier for beings with our sort of macroscopic experience to use and remember the equations.
I remember the big gaping hole left by my dad's absence in the months following the accident. He'd been the one who went to my parent-teacher conferences, the one who taught me mnemonics to memorize the Great Lakes and the Earth's atmospheres. Whenever I did something silly, my dad always made me feel better by telling me a story from the firehouse about someone who had done something even sillier. Sometimes you don't realize all the things a person does for you until they aren't there to do them anymore.
Childhood is a human water, a water which comes out of the shadows. This childhood in the mists and glimmers, this life in the slowness of limbo gives us a certain layer of births. What a lot of beings we have begun! What a lot of lost springs which have nevertheless, flowed! Reverie toward our past then, reverie looking for childhood seems to bring back lives which which have never taken place, lives which have been imagined. Reverie is a mnemonics of the imagination. In reverie we re-enter into contact with possibilities which destitute has not been able to make use of.
