It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. The Army component of the project was designated the Manhattan District; "Manhattan" gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (about $26 billion in 2013[1] dollars). Over 90% of the cost was for building factories and producing the fissionable materials, with less than 10% for development and production of the weapons. Research and production took place at more than 30 sites across the United States, the United Kingdom and Canada. Two types of atomic bomb were developed during the war. A relatively simple gun-type fission weapon was made using uranium-235, an isotope that makes up only 0.7 percent of natural uranium. Since it is chemically identical to the most common isotope, uranium-238, and has almost the same mass, it proved difficult to separate. Three methods were employed for uranium enrichment: electromagnetic, gaseous and thermal. Most of this work was performed at Oak Ridge, Tennessee. In parallel with the work on uranium was an effort to produce plutonium. Reactors were constructed at Oak Ridge and Hanford, Washington, in which uranium was irradiated and transmuted into plutonium. The plutonium was then chemically separated from the uranium. The gun-type design proved impractical to use with plutonium so a more complex implosion-type weapon was developed in a concerted design and construction effort at the project's principal research and design laboratory in Los Alamos, New Mexico. The first nuclear device ever detonated was an implosion-type bomb at the Trinity test, conducted at New Mexico's Alamogordo Bombing and Gunnery Range on 16 July 1945. Little Boy, a gun-type weapon, and the implosion-type Fat Man were used in the atomic bombings of Hiroshima and Nagasaki, respectively. In the immediate postwar years, the Manhattan Project conducted weapons testing at Bikini Atoll as part of Operation Crossroads, developed new weapons, promoted the development of the network of national laboratories, supported medical research into radiology and laid the foundations for the nuclear navy. It maintained control over American atomic weapons research and production until the formation of the United States Atomic Energy Commission in January 1947. In August 1939, prominent physicists Leó Szilárd and Eugene Wigner drafted the Einstein–Szilárd letter, which warned of the potential development of "extremely powerful bombs of a new type". It urged the United States to take steps to acquire stockpiles of uranium ore and accelerate the research of Enrico Fermi and others into nuclear chain reactions. They had it signed by Albert Einstein and delivered to President Franklin D. Roosevelt. Roosevelt called on Lyman Briggs of the National Bureau of Standards to head the Advisory Committee on Uranium to investigate the issues raised by the letter. Briggs held a meeting on 21 October 1939, which was attended by Szilárd, Wigner and Edward Teller. The committee reported back to Roosevelt in November that uranium "would provide a possible source of bombs with a destructiveness vastly greater than anything now known."[2] Briggs proposed that the National Defense Research Committee (NDRC) spend $167,000 on research into uranium, particularly the uranium-235 isotope, and the recently discovered plutonium.[3] On 28 June 1941, Roosevelt signed Executive Order 8807, which created the Office of Scientific Research and Development (OSRD),[4] with Vannevar Bush as its director. The office was empowered to engage in large engineering projects in addition to research.[3] The NDRC Committee on Uranium became the S-1 Uranium Committee of the OSRD; the word "uranium" was soon dropped for security reasons.[5] In Britain, Otto Frisch and Rudolf Peierls at the University of Birmingham had made a breakthrough investigating the critical mass of uranium-235 in June 1939.[6] Their calculations indicated that it was within an order of magnitude of 10 kilograms (22 lb), which was small enough to be carried by a bomber of the day.[7] Their March 1940 Frisch–Peierls memorandum initiated the British atomic bomb project and its Maud Committee,[8] which unanimously recommended pursuing the development of an atomic bomb.[7] One of its members, the Australian physicist Mark Oliphant, flew to the United States in late August 1941 and discovered that data provided by the Maud Committee had not reached key American physicists. Oliphant then set out to find out why the committee's findings were apparently being ignored. He met with the Uranium Committee, and visited Berkeley, California, where he spoke persuasively to Ernest O. Lawrence. Lawrence was sufficiently impressed to commence his own research into uranium. He in turn spoke to James B. Conant, Arthur Compton and George Pegram. Oliphant's mission was therefore a success; key American physicists were now aware of the potential power of an atomic bomb.[9][10] At a meeting between President Roosevelt, Vannevar Bush, and Vice President Henry A. Wallace on 9 October 1941, the President approved the atomic program. To control it, he created a Top Policy Group consisting of himself—although

  • Computer Simulations and the Trading Zone
    PETER &A Computer Simulations and the Trading Zone At the root of most accounts of the development of science is the covert premise that science is about ontology: What objects are there? How do they interact? And how do we discover them? It is a premise that underlies three distinct epochs of inquiry into the nature of science. Among the positivists, the later Carnap explicitly advocated a view that the objects of physics would be irretrievably bound up with what he called a "framework," a full set of linguistic relations such as is found in Newtonian or Eiustcini;~mechanics. That these frameworks held little in common did not trouble Car- nap; prediction mattered more than progress. Kuhn molded this notion and gave it a more historical focus. Unlike the positivists, Kuhn and other commentators of the 1960's wanted to track the process by which a community abandoned one framework and adopted another. To more recent scholars, the Kuhnian categoriza- tion of group affiliation and disaffiliation was by and large correct, but its underlying dynamics were deemed deficient because they paid insufficient attention to the sociological forces that bound groups to their paradigms. All three generations embody the root assumption that the analysis of science studies (or ought to study) a science classified and divided according to the objects of its inquiry. All three assume that as these objects change, particular branches of science split into myriad disconnected parts. It is a view of scientific disunity that I will refer to as "framework relativism. 55 In this essay, as before, I will oppose this view, but not by Computer Simulations I 19 invoking the old positivist pipe dreams: no universal protocol languages, no physicalism, no Corntian hierarchy of knowledge, and no radical reductionism.

  • The Real Holocaust
    THE REAL HOLOCAUST "Hitler will have no war, but he will be forced into it, not this year but later..." Emil Ludwig [Jew], Les Annales, June 1934 "We possess several hundred atomic warheads and rockets and can launch them at targets in all directions, perhaps even at Rome. Most European capitals are targets for our air force. Let me quote General Moshe Dayan: 'Israel must be like a mad dog, too dangerous to bother.' I consider it all hopeless at this point. We shall have to try to prevent things from coming to that, if at all possible. Our armed forces, however, are not the thirtieth strongest in the world, but rather the second or third. We have the capability to take the world down with us. And I can assure you that that will happen before Israel goes under." -- Martin van Creveld, Israeli professor of military history at the Hebrew University in Jerusalem in an interview in the Dutch weekly magazine: Elsevier, 2002, no. 17, p. 52-53. "We may never actually have to use this atomic weapon in military operations as the mere threat of its use will persuade any opponent to surrender to us." –Chaim Weizmann [Jew] "Jews Declared War on Germany. Even before the war started, the Jewish leaders on a worldwide basis had years before, declared that world Jewry was at war with Germany, and that they would utilize their immense financial, moral, and political powers to destroy Hitler and Nazi Germany. Principal among these was Chaim Weizmann, the Zionist leader, who so declared on September 5, 1939.

    Monte Carlo Simulation Techniques Ji Qiang Accelerator Modeling Program Accelerator Technology & Applied Physics Division Lawrence Berkeley National Laboratory CERN Accelerator School, Thessaloniki, Greece Nov. 13, 2018 Introduction: What is the Monte Carlo Method? • What is the Monte Carlo method? - Monte Carlo method is a (computational) method that relies on the use of random sampling and probability statistics to obtain numerical results for solving deterministic or probabilistic problems “…a method of solving various problems in computational mathematics by constructing for each problem a random process with parameters equal to the required quantities of that problem. The unknowns are determined approximately by carrying out observations on the random process and by computing its statistical characteristics which are approximately equal to the required parameters.” J. H. Halton, “A retrospective and prospective survey of the Monte Carlo Method,” SIAM Review, Vol. 12, No. 1 (1970). Introduction: What can the Monte Carlo Method Do? • Give an approximate solution to a problem that is too big, too hard, too irregular for deterministic mathematical approach • Two types of applications: a) The problems that are stochastic (probabilistic) by nature: - particle transport, - telephone and other communication systems, - population studies based on the statistics of survival and reproduction. b) The problems that are deterministic by nature: - the evaluation of integrals, - solving partial differential equations • It has been used in areas as diverse as physics, chemistry, material science, economics, flow of traffic and many others. Brief History of the Monte Carlo Method • 1772 Comte de Buffon - earliest documented use of random sampling to solve a mathematical problem (the probability of needle crossing parallel lines).

  • Oral History Interview with Nicolas C. Metropolis
    An Interview with NICOLAS C. METROPOLIS OH 135 Conducted by William Aspray on 29 May 1987 Los Alamos, NM Charles Babbage Institute The Center for the History of Information Processing University of Minnesota, Minneapolis Copyright, Charles Babbage Institute 1 Nicholas C. Metropolis Interview 29 May 1987 Abstract Metropolis, the first director of computing services at Los Alamos National Laboratory, discusses John von Neumann's work in computing. Most of the interview concerns activity at Los Alamos: how von Neumann came to consult at the laboratory; his scientific contacts there, including Metropolis, Robert Richtmyer, and Edward Teller; von Neumann's first hands-on experience with punched card equipment; his contributions to shock-fitting and the implosion problem; interactions between, and comparisons of von Neumann and Enrico Fermi; and the development of Monte Carlo techniques. Other topics include: the relationship between Turing and von Neumann; work on numerical methods for non-linear problems; and the ENIAC calculations done for Los Alamos. 2 NICHOLAS C. METROPOLIS INTERVIEW DATE: 29 May 1987 INTERVIEWER: William Aspray LOCATION: Los Alamos, NM ASPRAY: This is an interview on the 29th of May, 1987 in Los Alamos, New Mexico with Dr. Nicholas Metropolis. Why don't we begin by having you tell me something about when you first met von Neumann and what your relationship with him was over a period of time? METROPOLIS: Well, he first came to Los Alamos on the invitation of Dr. Oppenheimer. I don't remember quite when the date was that he came, but it was rather early on. It may have been the fall of 1943.

  • Doing Mathematics on the ENIAC. Von Neumann's and Lehmer's
    Doing Mathematics on the ENIAC. Von Neumann's and Lehmer's different visions.∗ Liesbeth De Mol Center for Logic and Philosophy of Science University of Ghent, Blandijnberg 2, 9000 Gent, Belgium [email protected] Abstract In this paper we will study the impact of the computer on math- ematics and its practice from a historical point of view. We will look at what kind of mathematical problems were implemented on early electronic computing machines and how these implementations were perceived. By doing so, we want to stress that the computer was in fact, from its very beginning, conceived as a mathematical instru- ment per se, thus situating the contemporary usage of the computer in mathematics in its proper historical background. We will focus on the work by two computer pioneers: Derrick H. Lehmer and John von Neumann. They were both involved with the ENIAC and had strong opinions about how these new machines might influence (theoretical and applied) mathematics. 1 Introduction The impact of the computer on society can hardly be underestimated: it affects almost every aspect of our lives. This influence is not restricted to ev- eryday activities like booking a hotel or corresponding with friends. Science has been changed dramatically by the computer { both in its form and in ∗The author is currently a postdoctoral research fellow of the Fund for Scientific Re- search { Flanders (FWO) and a fellow of the Kunsthochschule f¨urMedien, K¨oln. 1 its content. Also mathematics did not escape this influence of the computer. In fact, the first computer applications were mathematical in nature, i.e., the first electronic general-purpose computing machines were used to solve or study certain mathematical (applied as well as theoretical) problems.

We're here today. I'm Dag Spicer with the Computer History Museum. I'm here with Akrevoe Emmanou— Akrevoe Emmanouilides: Emmanouilides. Spicer: Emmanouilides. And could you just spell that for us so we have it on camera? Emmanouilides: Of course. My first name is A-k-r-e-v-o-e. My last name is E-m-m-a-n-o-u-i-l-i-d-e-s. And Akrevoe is the Greek word for expensive or precious, and Emmanouilides means the son of Emmanuel. Spicer: So that's a great name, great combination. Thanks for being with us today. I really appreciate that, and especially, you coming to visit us just kind of on a lark last week. You just came by to say hello and we met, and it turned out that you actually were present at some very important times in computer history. And before we get to those, I thought we'd just start out with your early childhood and where you grew up and maybe a bit about your parents and your schooling. Why don't we just start there? Emmanouilides: Fine. I was born in Philadelphia in 1928, September 11th, <laugh> coincidentally, which has become a very important day in our own history. I was raised in Philadelphia. My parents were immigrants; my father from the Ionian island of Lefkas, which is on the western coast of Greece, and my mother was from Turkey, from an area called Marmara.

  • People of the Hill—The Early Days
    Inspiration from the Past 2 Los Alamos Science Number 28 2003 Number 28 2003 Los Alamos Science 3 People of the Hill Preface In the first decade of its existence, 1943 to 1953, the Los Alamos Laboratory developed the fission weapon and the thermonuclear fusion weapon, popularly known as the atomic bomb and the hydrogen bomb. This memoir of that early period is one person’s viewpoint, the view of a man now over 80 years old, looking back on a golden time when he first arrived in Los Alamos with his new bride in March 1947. It is my recall, seasoned with the knowledge of a lifetime, of a new town and a new laboratory. Most of the scientists in this story were known to me personally. Others, I knew through the eyes of my young close friends. But my knowledge is only that of a student, blooming into scholarship in the presence of some of the master scientists of the era. That there is wonder and worship is no accident; these are my personal impres- sions, not the complete view of a skilled biographer. Of course, these people are far more complex than revealed to me by the professor-student relation. Also, I have stayed entirely within the period of that first decade, before the Oppenheimer security investigation, which polarized the scientific community and profoundly altered its rela- tionships. I have not permitted that tragic affair to rewrite the sentiments of the earlier time. So this account is not meant to be history’s dispassionate catalog of events.
