Part One: Foundations of Quantum Theory

This book of essays in four parts, was written over a decade and full of surprises for the breadth and variety of its subject matter. The first part is about the foundations of the quantum theory which reflects the author’s many conversations with the late John Bell who persuaded him that there is still no satisfactory interpretation of the theory.

Part Two: Nuclear Weapons

The second part deals with nuclear weapons. One of the essays concerns the creation of the modern gas centrifuge which was done by German prisoners of war in the Soviet Union. The proliferation of these centrifuges was one of the issues in the spread of nuclear weapons.

Part Three: Financial Engineering

The third section deals with financial engineering with a profile of Louis Bachelier, the French mathematician who created it at the beginning of the 20th century.

Part Four: The Higgs Boson

The final section deals with the Higgs boson and how it is used for generating mass. It includes a detailed article of how this mechanism works.
