The Development of Elementary Quantum Theory

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.

Metallic Magnetism</a>

Metallic Magnetism

The magnetism of iron and other transition metals had been a subject of inten sive research for a long time, but the understanding of the microscopic origin of „metallic magnetism“ was quite limited until the early 1970's. During the last 10 to 15 years both theory and experiment contributed towards signif icant progress in this field, such that today a qualitative understanding has been achieved.
