Theoretical physics is beset by a paradox that remains as mysterious
today as it was a century ago: at the subatomic level things are
simultaneously particles and waves. Like the duck-rabbit illusion first
described in 1899 by the Polish-born American psychologist Joseph
Jastrow, subatomic reality appears to us as two different categories of
But there is another paradox in play. Physics itself is riven by the
competing frameworks of quantum theory and general relativity, whose
differing descriptions of our world eerily mirror the wave-particle
tension. When it comes to the very big and the extremely small, physical
reality appears to be not one thing, but two. Where quantum theory
describes the subatomic realm as a domain of individual quanta, all
jitterbug and jumps, general relativity depicts happenings on the
cosmological scale as a stately waltz of smooth flowing space-time.
General relativity is like Strauss — deep, dignified and graceful.
Quantum theory, like jazz, is disconnected, syncopated, and dazzlingly
Physicists are deeply aware of the schizophrenic nature of their science
and long to find a synthesis, or unification. Such is the goal of a
so-called ‘theory of everything’. However, to non-physicists, these
competing lines of thought, and the paradoxes they entrain, can seem not
just bewildering but absurd. In my experience as a science writer, no
other scientific discipline elicits such contradictory responses.
