Otto Hahn and the Rise of Nuclear Physics by W.R. Shea Pdf

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.

The History of Early Nuclear Physics (1896-1931) by Milorad Mla?enovi? Pdf

This book covers the first 35 years of nuclear physics, especially in the areas of radioactivity and radioactive emissions which were the main discoveries in nuclear physics during its first three decades. It follows the nuclear phenomena step by step, paying special attention to outstanding discoveries, such as Curie's discovery of radium, Rutherford-Soddy law, discovery of isotopes, and Rutherford's artificial transmutations. The author aims to present in a critical approach the growth of nuclear physics as seen by a nuclear physicist and historian.

The Woman Who Split the Atom by Marissa Moss Pdf

Bestselling author-illustrator Marissa Moss tells the gripping story of Lise Meitner, the physicist who discovered nuclear fission As a female Jewish physicist in Berlin during the early 20th century, Lise Meitner had to fight for an education, a job, and equal treatment in her field, like having her name listed on her own research papers. Meitner made groundbreaking strides in the study of radiation, but when Hitler came to power in Germany, she suddenly had to face not only sexism, but also life-threatening anti-Semitism as well. Nevertheless, she persevered and one day made a discovery that rocked the world: the splitting of the atom. While her male lab partner was awarded a Nobel Prize for the achievement, the committee refused to give her any credit. Suddenly, the race to build the atomic bomb was on—although Meitner was horrified to be associated with such a weapon. “A physicist who never lost her humanity,” Meitner wanted only to figure out how the world works, and advocated for pacifism while others called for war. The book includes an afterword, author's note, timeline, select terms of physics, glossary of scientists mentioned, endnotes, select bibliography, index, and Marissa Moss’s celebrated drawings throughout. The Woman Who Split the Atom is a fascinating look at Meitner’s fierce passion, integrity, and her lifelong struggle to have her contributions to physics recognized.

Heavy Water and the Wartime Race for Nuclear Energy by Per F Dahl Pdf

Heavy water (deuterium oxide) played a sinister role in the race for nuclear energy during the World War II. It was a key factor in Germany's bid to harness atomic energy primarily as a source of electric power; its acute shortage was a factor in Japan's decision not to pursue seriously nuclear weaponry; its very existence was a nagging thorn in the side of the Allied powers. Books and films have dwelt on the Allies' efforts to deny the Germans heavy water by military means; however, a history of heavy water has yet to be written. Filling this gap, Heavy Water and the Wartime Race for Nuclear Energy concentrates on the circumstances whereby Norway became the preeminent producer of heavy water and on the scientific role the rare isotope of hydrogen played in the wartime efforts by the Axis and Allied powers alike. Instead of a purely technical treatise on heavy water, the book describes the social history of the subject. The book covers the discovery and early uses of deuterium before World War II and its large-scale production by Norsk Hydro in Norway, especially under German control. It also discusses the French-German race for the Norwegian heavy-water stocks in 1940 and heavy water's importance for the subsequent German uranium project, including the Allied sabotage and bombing of the Norwegian plants, as well as its lesser role in Allied projects, especially in the United States and Canada. The book concludes with an overall assessment of the importance and the perceived importance of heavy water for the German program, which alone staked everything on heavy water in its quest for a nuclear chain reaction.

The Pope of Physics by Gino Segrè,Bettina Hoerlin Pdf

Enrico Fermi is unquestionably among the greats of the world's physicists, the most famous Italian scientist since Galileo. Called the Pope by his peers, he was regarded as infallible in his instincts and research. His discoveries changed our world; they led to weapons of mass destruction and conversely to life-saving medical interventions. This unassuming man struggled with issues relevant today, such as the threat of nuclear annihilation and the relationship of science to politics. Fleeing Fascism and anti-Semitism, Fermi became a leading figure in America's most secret project: building the atomic bomb. The last physicist who mastered all branches of the discipline, Fermi was a rare mixture of theorist and experimentalist. His rich legacy encompasses key advances in fields as diverse as comic rays, nuclear technology, and early computers. In their revealing book, The Pope of Physics, Gino Segré and Bettina Hoerlin bring this scientific visionary to life. An examination of the human dramas that touched Fermi’s life as well as a thrilling history of scientific innovation in the twentieth century, this is the comprehensive biography that Fermi deserves.
