Book Description
The story of two close friends who discovered nuclear fission is told in great detail within the context of both World Wars. This video is as much about role of scientists in political events, social responsibility, and discrimination against women and Jews, as it is about the science, though the science is clearly explained. Archival film footage and photographs are extensively and effectively used throughout the production. Most fascinating are the contrasting life choices made by these two scientists. They were close collaborators and good friends during the first 20 years of their professional life. However, Lise Meitner, a physicist, faced early discrimination as a woman and later as a Jew. She was forced to flee Germany as the Nazis established their hold over the country in the 1930s. Though given the opportunity, she refused to participate in the U.S. Manhattan project to develop the atomic bomb. Otto Hahn, a chemist, ended up collaborating and being a key leader of the Nazi wartime atomic project. Though he secretly collaborated with Lise in exile, he refused to acknowledge her role in explaining nuclear fission, taking sole credit and ultimately the Nobel Prize for this discovery. Yet Lise actually coined the term “nuclear fission” and worked out the actual physics in the first published explanation of the phenomena.. The film honestly discusses the horrors of Nazism including the concentration camps, the tendency of scientists to care about science above all considerations, and the politics of science achievements and their recognition. It clearly demonstrates the irony of German scientists, many of whom were philosophically opposed to Hitler, making serious moral compromises by directly assisting the Nazi war effort in order to continue their scientific research and keep their positions within their institutions. Hence, this video can be an excellent starting point for a wealth of historical, political, moral, civil rights, and social issues. This is a well-done, serious history and will be most appreciated by serious students. - Ben Wagner, University of Buffalo.

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
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
Nuclear Fusion and Fission delves into nuclear physics and the scientists responsible for the discovery of splitting and fusing an atom. The book begins with the very basic building blocks of science, breaking down the different types of energy and how we use them, the materials that make up an atom, and our search for the perfect renewable energy source. Set against the cultural backdrop of World War II, later chapters follow each significant theory that led to the creation of the world’s most dangerous weapon as well as some of its most widely used medical and food production processes today.

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.
