...Engineering Physics University of Wisconsin September 23, 1997 | To: From: Subject: | Professor Michael Alley Cindy Reese CTR Request to Research How Credit Was Awarded for the Discovery of Nuclear Fission | For my EPD 397 project, please grant me permission to study the way in which credit has been awarded for the discovery of nuclear fission. Although Otto Hahn received the 1946 Nobel Prize in Chemistry for the discovery, several people assert that Lise Meitner and Fritz Strassman should have also received credit. In my research, I will attempt to discern how credit should have been bestowed. This topic meets the criteria for a successful topic in this course. First, I am interested in the topic. As a nuclear engineering student, I realize that the discovery of nuclear fission was perhaps the single most important discovery this century in my field. As a woman scientist, I am also deeply interested in the successes and challenges faced by other women scientists. A second way in which this topic meets the criteria is that it can be quickly researched. A computer search in the library has revealed many sources available on this topic. Attached to this memo is a summary of one such source, Lise Meitner: A Life in Physics by Ruth Sime. This topic also meets the third criterion for a successful topic in this course, namely, that it be technical. The fission of a uranium nuclear involves an understanding of both chemistry and physics principles. By focussing on this...

...In 1938 Otto Hahn and Fritz Strassman were two German scientists who demonstrated nuclear fission. Nuclear fission released an enormous amount of energy called nuclear energy that can be used in many ways, including a dangerous weapon. They found that they could split the nucleus of a uranium atom by bombarding it with neutrons. As a result, the uranium nucleus splits some of its mass to be converted to energy. Other physicists noticed that the fission of one uranium atom gave off extra neutrons, which could in turn split other uranium atoms, starting a chain reaction. Therefore, in theory this energy could be harnessed to make a powerful bomb. Due to this, the development of the ultimate power took many scientists a lot of hard work and dedication to create such an effective bomb. First and foremost, there were problems with the political and social climate of the world that caused a race to unfold in the development of the ultimate weapon. During this period of time World War II was going on, and the United States was fighting with Germany in the Atlantic, as well as Japan in the Pacific. It all started when Adolf Hitler and the Nazis attacked Poland on September 1, 1939, in which the other countries had joined the war for help. As a result, when Leo Szilard heard that Germany had found out about Hahn and Strassman’s discovery he thought they would produce a bomb. Leo Szilard told them that they were attempting to purify Uranium-235, which would make up the atomic bomb. With...

...integrally masculine venture. The notion that mathematics and science were unsuitable or ‘hard’ for women, and even ‘at odds’ with real femininity, can be trailed back to the beginning of modern science and the commencement of the Royal Society in the seventeenth century. Then ‘femininity’ became the exact opposite of the new, masculine, experimental science of Newton and his colleagues who needed to break from the passive, reflective analytical style of outdated ‘natural philosophy’, the former word for science. (Schiebinger, 1996). This divide that detached women from the new experimental science, was made a lot wider by the Nature’s tradition being embodied in female form only. The masculine scientists made ‘mother nature’ their goal of research, and branded her as a female muse who could trick them, but if trained would also permit them to ‘enter her secrets’. This entire trap cast femininity as the inactive, topic of investigation and the male as the virile, enthusiastic investigator; a dualism that just increased the difference between science and femininity (Jordanova, 1991). Regardless of this, there existed women scientists— botanists, mathematicians, astronomers chemists and more—who took part in science in the seventeenth and eighteenth centuries. Actually, Ann Whitfield, who wrote on the outcomes of a thunderstorm in Rickmansworth, Hertfordshire, in 1760 was the first female to have published an article to the Royal Society’s Philosophical Transactions. In the end of the...

LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1]. It is also known as additive fabrication, additive processes, direct digital...

...Bloodlines of Illuminati by: Fritz Springmeier, 1995 Introduction: I am pleased & honored to present this book to those in the world who love the truth. This is a book for lovers of the Truth. This is a book for those who are already familiar with my past writings. An Illuminati Grand Master once said that the world is a stage and we are all actors. Of course this was not an original thought, but it certainly is a way of describing the Illuminati view of how the world works. The people of the world are an audience to which the Illuminati entertain with propaganda. Just one of the thousands of recent examples of this type of acting done for the public was President Bill Clinton’s 1995 State of the Union address. The speech was designed to push all of the warm fuzzy buttons of his listening audience that he could. All the green lights for acceptance were systematically pushed by the President’s speech with the help of a controlled congressional audience. The truth on the other hand doesn’t always tickle the ear and warm the ego of its listeners. The light of truth in this book will be too bright for some people who will want to return to the safe comfort of their darkness. I am not a conspiracy theorist. I deal with real facts, not theory. Some of the people I write about, I have met. Some of the people I expose are alive and very dangerous. The darkness has never liked the light. Yet, many of the secrets of the Illuminati are locked up tightly simply because secrecy is a way...
