Quantum mechanics, formulated by Werner Heisenberg in 1925, belongs among the greatest achievements of physics. "Fundamental Physics: Heisenberg and Beyond" combines personal tributes to Werner Heisenberg with assessments of his impact on current and future developments in physics. The first part presents two essays commemorating Werner Heisenberg's 100th birthday, and these are complemented by a short and nicely illustrated biographical note in the appendix. In the second part, incisive articles by ten world-leading scientists explain important developments in fundamental physics to a broader community of interested scientists.
