To use an example of Waddington (1961, p. 20), sodium chloride molecules exhibit properties which we can not observe by studying sodium and chlorine atoms in isolation.

Just as the discovery that sodium chloride has properties not exhibited by sodium and chlorine in isolation tells us something about the nature of sodium and chlorine which we could not otherwise know, so too the existence of subjectivity in combinations of atoms that make human brains tells us something about the nature of those atoms that make those brains.

When the compound sodium chloride is formed, it is not that something entirely new is added to sodium and chlorine atoms, but rather we now know something more about the nature of sodium and chlorine atoms then we did before.

Sodium atoms are just as much «conformists» inside the body as outside it, but the pattern of physical feeling to which they conform is different in the body.

To see dynamical tunneling in action, two teams — one based at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, the other at the University of Texas, Austin — first used a complicated series of laser beams and magnetic fields to cool atoms of cesium or sodium to a temperature of a few billionths of a degree above absolute zero.

What happens is this: The condensate contains sodium atoms held in place by a magnetic field and illuminated by a «coupling» laser that serves to make the condensate transparent to a specific frequency of light.

When the coupling laser came back on, the incoming jolt of energy caused the altered sodium atoms to shift energy levels, in the process releasing a light pulse of the exact phase and amplitude as the one originally sent in by the probe laser.
