Beyond Uncertainty:
Heisenberg, Quantum Physics, and the Bomb

By David C. Cassidy

A new book on Heisenberg, based on the author's prize winning and critically acclaimed Uncertainty: The Life and Science of Werner Heisenberg.

Werner Heisenberg (1901-1976) was one of the most brilliant and renowned physicists of his day. A Nobel laureate at the age of 32, his masterpiece was his articulation of the Uncertainty Principle.

Heisenberg's life was one of dramatic controversy as well as spectacular triumph. Unwilling to leave his beloved homeland, Germany, he played a major role in conducting nuclear research during World War II.

Uncertainty was published to resounding acclaim and two national awards. Richard Rhodes (The Making of the Atom Bomb) called it "the definitive biography of a great and tragic physicist."

In Beyond Uncertainty, Cassidy offers a broadly accessible account of Heisenberg's contributions to quantum physics, and he explores previously unknown material regarding the scientist's personal responsibility and guilt when serving an abhorrent military regime.
