'Bokulich fully appreciates many subtleties that practising physicists occasionally understand intuitively, but are rarely explicit about. Her ideas are refreshing and original and presented with clarity and erudition. I unreservedly recommend her book to anyone wanting to understand the intricate connections between the classical and quantum worlds.' Sir Michael Berry
