This book traces the evolution of the ideas that eventually resulted in the elementary quantum theory in 1925/26. Further, it discusses the essential differences between the fundamental equations of Quantum Theory derived by Born and Jordan, logically comprising Quantum Mechanics and Quantum Optics, and the traditional view of the development of Quantum Mechanics. Drawing on original publications and letters written by the main protagonists of that time, it shows that Einstein’s contributions from 1905 to 1924 laid the essential foundations for the development of Quantum Theory. Einstein introduced quantization of the radiation field; Born added quantized mechanical behavior. In addition, Born recognized that Quantum Mechanics necessarily required Quantum Optics; his radical concept of truly discontinuous and statistical quantum transitions (“quantum leaps”) was directly based on Einstein’s physical concepts.

This book in a single contribution for the first time examines the historical development of the concepts of vortex, vorticity, knot, chirality, and helicity between 1517 and 1969. It considers their origins in early pictorial and conceptual studies, their subsequent formalization in mathematical analysis, and their eventual consolidation as interconnected elements within fluid mechanics, mathematical physics, geophysics, and astrophysics.

Attention is given to the progression from qualitative representations to formal definitions, including the emergence of vorticity, curl, and the gradient operator, as well as to the introduction of knot, chirality, and helicity as new means of describing physical and geometrical structure. The discussion emphasizes the extent to which these notions evolved in parallel, with recurring intersections between geometry, physics, and analysis.

The volume is intended for undergraduate and postgraduate students and researchers in applied mathematics, fluid mechanics, dynamo theory, topology, knot theory, geophysics, astrophysics, and the history of mathematical physics.
