If I set up waves with known amplitudes and synthesize them, I'll find that for essentially all random combinations of phases, the thing I get is an object not confined. It takes a very clever combination of the phases of all those waves to add up to something in only one region; and cancel out everywhere else.

But if it were just combining waves with a definite oscillation and adding them up, that would be a piece of cake for a computer to do.

We know virtually all of the genes known to mammals. We do not know all of the combinations.

He had appeared beside her because she had wanted him to. She had called him to her, and was calling him still. Even when she fell asleep, she dreamed of water, as if the world were topsy-turvy and everything she cared about had been lost in the deep. She plunged through the green waves with her eyes wide open, searching for the world as she'd known it, but that world no longer existed; everything that had once been solid was liquid now, and the birds swam alongside the fish.

Essentially, the waves that traveled through the area outside the inner core?the crust, the mantle, the outer core?are all the same. Only when they travel through the inner core are they different.

Waves tossed themselves against the shore, dragging grit and sand between their nails as they were slowly pulled back out to sea.
