Georges Charpak, a French citizen, was born on August 1, 1924 in Poland.
These characteristics of Charpak's detector - high spatial resolution and high repetition rate - were particularly important in the study of rare interactions or the creation of short-lived exotic particles which often necessitate the use of intense beams and the sampling of a large number of events in a short period of time.

Georges Charpak is a member of the French Académie des Sciences and of the U.S. National Academy of Sciences.
In Megawatts and Megatons, two of the world’s most eminent physicists—French Nobel Prize laureate Georges Charpak and American Enrico Fermi Award–winner Richard L. Garwin—assess with consummate authority the benefits of nuclear energy and the dangers of nuclear weaponry.
Meanwhile, nuclear power already provides one-sixth of all electrical energy in the world—France, for instance, derives 80% of its electricity from reactors— but nuclear power has met with great resistance in the United States, where the specter of the Three Mile Island breakdown still looms in the public’s consciousness.

In Megawatts and Megatons, world-renowned physicists Richard L. Garwin and Georges Charpak offer an accessible, eminently well-informed primer on two of the most important issues of our time: nuclear weapons and nuclear power.
Making a strong and eloquent argument in favor of arms control, Garwin and Charpak outline specific strategies for achieving this goal worldwide.
But they also demonstrate how nuclear power can provide an assured, economically feasible, and environmentally responsible source of energy—in a way that avoids the hazards of weapons proliferation.
