Book Description
and less as the emanation unden\'ent radioactive decay, and it became motion less after about 30 seconds. Since this process was occurring very rapidly, Hahn and Sackur marked the position of the pointer on a scale with pencil marks. As a timing device they used a metronome that beat out intervals of approximately 1. 3 seconds. This simple method enabled them to determine that the half-life of the emanations of actinium and emanium were the same. Although Giesel's measurements had been more precise than Debierne's, the name of actinium was retained since Debierne had made the discovery first. Hahn now returned to his sample of barium chloride. He soon conjectured that the radium-enriched preparations must harbor another radioactive sub stance. The liquids resulting from fractional crystallization, which were sup posed to contain radium only, produced two kinds of emanation. One was the long-lived emanation of radium, the other had a short life similar to the emanation produced by thorium. Hahn tried to separate this substance by adding some iron to the solutions that should have been free of radium, but to no avail. Later the reason for his failure became apparent. The element that emitted the thorium emanation was constantly replenished by the ele ment believed to be radium. Hahn succeeded in enriching a preparation until it was more than 100,000 times as intensive in its radiation as the same quantity of thorium.

Book Description
A "mesmerizing" re-imagination of the final months of World War II (Kate Quinn, author of The Alice Network), Hannah's War is an unforgettable love story about an exceptional woman and the dangerous power of her greatest discovery. Berlin, 1938. Groundbreaking physicist Dr. Hannah Weiss is on the verge of the greatest discovery of the 20th century: splitting the atom. She understands that the energy released by her discovery can power entire cities or destroy them. Hannah believes the weapon's creation will secure an end to future wars, but as a Jewish woman living under the harsh rule of the Third Reich, her research is belittled, overlooked, and eventually stolen by her German colleagues. Faced with an impossible choice, Hannah must decide what she is willing to sacrifice in pursuit of science's greatest achievement. New Mexico, 1945. Returning wounded and battered from the liberation of Paris, Major Jack Delaney arrives in the New Mexican desert with a mission: to catch a spy. Someone in the top-secret nuclear lab at Los Alamos has been leaking encoded equations to Hitler's scientists. Chief among Jack's suspects is the brilliant and mysterious Hannah Weiss, an exiled physicist lending her talent to J. Robert Oppenheimer's mission. All signs point to Hannah as the traitor, but over three days of interrogation that separate her lies from the truth, Jack will realize they have more in common than either one bargained for. Hannah's War is a thrilling wartime story of loyalty, truth, and the unforeseeable fallout of a single choice.

Book Description
This biography of Lise Meitner (1878-1968), the Austrian Jewish female physicist at the heart of the discovery of nuclear fission, also looks at major developments in physics during her life. Meitner was a colleague and friend of many giants of 20th century physics: Max Planck, her Berlin mentor, Einstein, von Laue, Marie Curie, Chadwick, Pauli and Bohr. She was the first woman to earn a Ph.D. in physics at the University of Vienna, a pioneer in the research of radioactive processes and, together with her nephew Otto Robert Frisch, an interpreter of the process of nuclear fission in 1938. Yet at the end of World War II, her colleague of thirty years, radiochemist Otto Hahn alone was awarded the 1944 Nobel Prize in Chemistry for the “discovery” of nuclear fission — a discovery based on years of research in which Meitner was directly involved before her secret 1938 escape from Nazi Germany to Sweden. “A story of one of the half dozen most remarkable women of the 20th century.” — John Archibald Wheeler, Princeton University “Patricia Rife’s biography truly brings Meitner to life, both as a scientist and as a woman... Rife weaves Meitner’s personal struggles into the social and political fabric of her times. For example, the story of Meitner’s early career is told against the backdrop of the development of the new physics, with plentiful illumination of the limited prospects for women scientists in the German-speaking world during the early twentieth century. When Meitner's story enters the Nazi era — including her escape from Germany — it is as riveting as the best novel.” — Catherine Westfall,Technology and Culture “A well-written, thorough, readable and engrossing work.” — Gary Goldstein, Peace and Change: a Journal of Peace Research “Rife has produced an exciting book, which reads like a novel and she gives justice to Meitner’s life full of science and human stories... [The] book is a beautiful tribute to an outstanding scientist; it has a lot to teach us about our world; and it is a great read. I warmly recommend it to everyone interested in science and in history.” — Structural Chemistry “Lise Meitner comes to life as author Rife skillfully weaves social, political, and scientific events into a well-researched and documented work. Lists of Meitner’s awards and publications and an extensive bibliography complete this excellent book.” — Association of Women in Science Magazine “The dramatic tale of the discovery of nuclear fission on the eve of WWII... not just a story of ideas... but also of the social and intellectual milieu in which these ideas were developed. It is also the story of how a shy, self-effacing young woman, through talent and hard work, became a world-class scientist... Rife tells this story very well.” — The Antioch Review “The particular merit of Rife’s biography of Austrian physicist Meitner is that it places her life and work within the historical context... It is comprehensive, generally clearly written... and appropriate for undergraduate students. Just enough science is included as to make clear the significance of her work... Extensive bibliography, informative footnotes.” — Choice

Book Description
Otto Robert Frisch took part in some of the most momentous developments in modern physics, notably the discovery of nuclear fission (a term which he coined). His work on the first atom bomb, which he saw explode in the desert “like the light of a thousand suns”, brought him into contact with figures such as Robert Oppenheimer, Edward Teller, Richard Feynman and the father of electronic computers, John von Neumann. He also encountered the physicists who had made the great discoveries of recent generations: Einstein, Rutherford and Niels Bohr. This characterful book of reminiscences sheds an engagingly personal light on the people and events behind some of the greatest scientific discoveries of this century, illustrated with a series of fascinating photographs and witty sketches by the author himself. “This is a happy book, from which the author's personality and his enjoyment of physics, of music, of life, emerges clearly. It is also a portrait of the pre-War world of physics, of days of small numbers and small apparatus, of times when a physicist could think of an ingenious experiment today and set it up tomorrow.” — Rudolf Peierls, Nature “In writing a charming, light-hearted cameo of his life and times as a scientist, Professor Frisch has revealed more about science than many authors with greater pretensions. This is a book that deserves to be read, and will be enjoyed, by a wide audience.” — The Economist “Despite his modest title, what Frisch ‘manages to remember’ is quite impressive. He loved to tell stories and his many vignettes of his associates... include nearly every outstanding physicist who worked in nuclear physics.” — Science “In the straightforward narrative style he developed writing lay treatments of modern physics, Frisch recounts his memories of significant men and events in the history of physics between 1920 and 1960... Frisch tells his stories well...” — Robert W. Seidel,Isis, A Journal of the History of Science Society

Book Description
The book describes how Lisa Meitner, of Jewish heritage, found herself working as a physicist at the Kaiser Wilhelm Institute in Berlin when the Nazis came to power in 1933; how she was hounded out of the country and forced to relocate to Sweden; how German chemists Otto Hahn and Fritz Strassman continued with the project - on the effect of bombarding uranium (the heaviest known element at the time) with neutrons, a project which Lise herself had initiated, being the intellectual leader of the group. It describes how Hahn and Strassmann, with whom she kept in touch, came up with some extraordinary results which they were at a loss to explain; how Lise, and her nephew Otto Frisch, who was also a physicist, confirmed what they had achieved - the 'splitting of the atom', no less, and provided them with a theoretical explanation for it. This laid the foundation for nuclear power, medical-scanning technology, radiotherapy, electronics, and of course, the atomic bomb - the creation of which filled Lise with horror. It describes the crucial part that Lise played in our understanding of the world of atoms, and how deliberate and strenuous attempts were made to deny her contribution; to belittle her achievements, and to write her out of the history books, even though Albert Einstein said she was even 'more talented than Marie Curie herself'. The author is fortunate and honoured to have been granted several interviews with Lise's nephew Philip Meitner - himself a refugee from the Nazis - who with his wife Anne, provided much valuable information and many photographs.

Book Description
From April through December of 1945, ten of Nazi Germany's greatest nuclear physicists were detained by Allied military and intelligence services in a kind of gilded cage at Farm Hall, an English country manor near Cambridge. The physicists knew the Reich had failed to develop an atomic bomb, and they soon learned, from a BBC radio report on August 6, that the Allies had succeeded in their own efforts to create such a weapon. But what they did not know was that many of their meetings and private conversations were being monitored and recorded by British agents. This book contains the complete collection of transcripts that were made from these secret recordings, providing an unprecedented view of how the German scientists, including two Nobel Laureates, thought and spoke about their roles during the war.
