Here's a quote from James Gleick's: _Genius_ that I think fits this topic well: "Someone who trusts science to explain the everyday must continually make connections between textbook knowledge and real knowledge, the knowledge we receive and the knowledge we truly own. We are told when we are young that the earth is round, that it circles the sun, that it spins on a tilted axis. We may accept the teaching on faith, the frail teaching of a modern secular religion. Or we may solder these strands to a frame of understanding from which it may not be so easily be disengaged. We watch the sun's arc fall in the sky as winter approaches. We guess the time from the shadow of a lamppost. We walk across a merry-go-round and strain against the sideways Coriolus force, and we are trying to connect the sensation to our received knowledge of the habits of earthly cyclones: northern hemisphere, low pressure, counter-clockwise. We time the vanishing point of a tall-masted ship below the horizon. The sun, the wind, the waves all join in preventing our return to a flat-earth world, where we could watch the tides follow the moon without understanding." James Gleick: _Genius_ Robert O.
