In the past four decades, there has been growing interest in the exciting new topic of physics in low dimensions. Thousands of original ideas have been proposed in the literature, and some are confirmed experimentally, along with several Nobel prizes which have been awarded in this field.

1. Introduction: From giants to dwarfs. 2. Down to low dimensions. 3. The quantum dot: In the abyss of no dimensions. 4. Quantum rings: Dynamic unity of polar opposites. 5. Graphene: Carbon and its nests. 6. Some remarkable episodes in the nanoscale. 7. Epilog and the road ahead.
