Odd Sympathy

Laid up in bed during a brief illness and idly watching two clocks mounted in one case, Huygens noticed something strange: No matter how the pendulums started out, eventually they always ended up swinging in exactly opposite directions. Huygens wondered whether this odd sympathy might solve the longitude problem. Perhaps, he thought, two such clocks could regulate each other. If one got dirty, for instance, and started running slow, the influence of the other clock would lessen this effect. I...

 The Concept of the Chemical Bond

[The chemical bond] First, it is related to the disposition of two electrons (remember, no one has ever seen an electron!): next, these electrons have their spins pointing in opposite directions (remember, no one can ever measure the spin of a particular electron!): then, the spatial distribution of these electrons is described analytically with some degree of precision (remember, there is no way of distinguishing experimentally the density distribution of one electron from another!): concept...

 Science Runs Forward, Religion Runs Backwards

Let me posit a difference between religion and science. Religion: Future>Present>Past Science: Past>Present>Future. Let me explain. Religion, as it has traditionally been understood in its institutional guise, begins with the dream of a comforting future. An escape from the apparently inescapable reality of death. Which impacts our daily lives in the present. Determines, for example, codes of morality, inspires great deeds of goodness or mayhem. Mandates rites and rituals. ...

 The Wonder of Birds Flocking

What is remarkable about the starlings' behaviour is that, despite all appearances, there is no choreographer and, as far as we know, no leader. Each individual bird is just following local rules. The numbers of individual birds in these flocks can run into thousands, yet they almost literally never collide. That is just as well for, given the speed at which they fly, any such impact would severely injure them. Often the whole flock seems to behave as a single individual, wheeling and turnin...
