  • Edward M. Eyring
    The Chemistry Department 1946-2000 Written by: Edward M. Eyring Assisted by: April K. Heiselt & Kelly Erickson Henry Eyring and the Birth of a Graduate Program In January 1946, Dr. A. Ray Olpin, a physicist, took command of the University of Utah. He recruited a number of senior people to his administration who also became faculty members in various academic departments. Two of these administrators were chemists: Henry Eyring, a professor at Princeton University, and Carl J. Christensen, a research scientist at Bell Laboratories. In the year 2000, the Chemistry Department attempts to hire a distinguished senior faculty member by inviting him or her to teach a short course for several weeks as a visiting professor. The distinguished visitor gets the opportunity to become acquainted with the department and some of the aspects of Utah (skiing, national parks, geodes, etc.) and the faculty discover whether the visitor is someone they can live with. The hiring of Henry Eyring did not fit this mold because he was sought first and foremost to beef up the graduate program for the entire University rather than just to be a faculty member in the Chemistry Department. Had the Chemistry Department refused to accept Henry Eyring as a full professor, he probably would have been accepted by the Metallurgy Department, where he had a courtesy faculty appointment for many years. Sometime in early 1946, President Olpin visited Princeton, NJ, and offered Henry a position as the Dean of the Graduate School at the University of Utah. Henry was in his scientific heyday having published two influential textbooks (Samuel Glasstone, Keith J.

  • Electrochemist and Cold Fusion Pioneer Dr. Martin
    Martin Fleischmann’s Historic Impact Compiled by Christy L. Frazier, with assistance from Michael McKubre and Marianne Macy lectrochemist and cold fusion pioneer Dr. Martin Fleischmann passed away on August 3 in the comfort E of his home in Salisbury, England, with his family by his side. He was 85. Fleischmann was born March 29, 1927 in Karlovy Vary, Czechoslovakia to a Jewish father and Catholic mother. In a 1996 interview with Chris Tinsley in IE #11 (http://www.infinite-energy.com/iemagazine/issue11/ fleishmann.html), Fleischmann related a harrowing story about his family’s escape from Nazi-occupied Czechoslovakia in 1938: “I always tell people I had the unique and unpleasurable experience of being arrested by the Gestapo at the age of 11...[M]y father was very badly beaten up by the Nazis. However, we got out. We were driv- en across the border by a First World War comrade-in-arms of my father...At that time, my parents also got permission to come to England, and we all got on the train in Prague and came to the Dutch border and the Germans cleared the train of all refugees and we were in the last coach and my father said, ‘No, sit tight, don’t get off the train,’ and the train pulled out of the station. So that’s how we got away the second time, and arrived at Liverpool Street Station with 27 shillings and sixpence between the four of us.” Fleischmann’s father died soon after the family emigrated to England, as a result of his mistreatment at the hands of Nazis.

  • An Interview with Professor Martin Fleischmann
    An Interview with Professor Martin Fleischmann By Christopher P. Tinsley Reprinted courtesy of and originally published in Infinite Energy Magazine Issue #11 http://www.infinite-energy.com/iemagazine/issue11/fleishmann.html November 1996 Christopher Tinsley: Now that you are retired from IMRA, what do you intend to do? Are you really retired? Martin Fleischmann: I don't suppose I'll ever retire completely. I retired from full-time work at the University of Southampton when I was age 56, but I didn't "retire." I started a number of part-time projects and, eventually, of course went full-time to IMRA Europe. At the moment I am taking a very careful look at some of the work which we have done in the past. It has been suggested at various times that I should start an operation in the United Kingdom but--bearing in mind my age and medical history--I think this would be not a very sensible way to go forward. So I am now interacting strongly with a group in Italy. I anticipate that we will take a very careful look at what we and other people have done during the past eight years and move on eventually to try to implement some of the work which I have wanted to carry out in the past. T: You've been giving some assistance to Mr. Evan Ragland with regard to his cell. This cell is of course the one which our magazine is hoping to provide to people as a demonstration device of the basic thermal effect.

  • COLD NUCLEAR FUSION from Pons & Fleischmann to Rossi's E-Cat
    COLD NUCLEAR FUSION from Pons & Fleischmann to Rossi's E-Cat by Martin Bier Twenty-two years have passed since Pons and Fleischmann held their legendary press conference. Presumably, they had realized cold fusion. But it became a classic case of pride before the fall. A few months later, after the results appeared irreproducible, the American Physical Society and the authoritative journals declared it pseudoscience. Nevertheless, cold fusion never totally disappeared. Money has continued to be poured into it and researchers are still working on it. Recently, there has been commotion over an alleged "breakthrough" by Andrea Rossi with his E-Cat. But there are indications that Rossi's E-Cat is a sham. ! PONS EN FLEISCHMANN Martin Fleischmann (1927) was an accomplished British elektrochemist. He had been president of the International Society of Electrochemistry for two years. In 1986, he was allowed to join the Fellowship of the Royal Society. After 1983, he no longer had any teaching duties at the University of Southampton and started spending a lot of time doing research at the University of Utah. Stanley Pons (1943) was from Valdese, North Carolina. He interrupted his chemistry studies for eight years to help run the family business. But in 1975 he picked it up again and in 1978 he received his Ph.D. from the University of Southampton. In 1989, he was head of the chemistry department at the The front cover of Time on May 8, 1989.!

    http://www.nytimes.com/2012/08/12/science/martin-fleischmann-cold-fusion- seeker-dies-at-85.html August 11, 2012 Martin Fleischmann, Seeker of Cold Fusion, Dies at 85 By DOUGLAS MARTIN Martin Fleischmann made the greatest discovery since fire: replicating the furnace of the sun at room temperature in a jar of water, essentially solving the world’s energy needs forever. That is how Dr. Fleischmann might have liked his obituary to read. On March 23, 1989, when he and a colleague announced that they had achieved nuclear fusion in their laboratory, it even seemed possible. News reports heralded the scientists’ “star in a jar.” But when Dr. Fleischmann died at age 85 on Aug. 3 at his home in Tisbury, England, what had once seemed the peak achievement of a highly honored electrochemist had long been discredited. His dream of generating more energy from an enclosed space than was put into it is still being pursued. His friend Steven B. Krivit, who confirmed the death, edits an online newsletter, New Energy Times, to report on developments in the field. He said that Dr. Fleischmann suffered from heart ailments, Parkinson’s disease and diabetes. What Dr. Fleischmann and B. Stanley Pons did at the University of Utah sounds like a high-school science project. The ingredients were a jar of water, an electrical current and a cathode made of palladium, a rare metal. The theory was that a continuous stream of electrical current would release hydrogen atoms from the water, and that they would be absorbed by the palladium.

In a day when there are influential religious leaders, such as Pat Robertson, preaching and sincerely believing that the entire vast physical universe is only about 7,500 years old, there is the most urgent need for books like No Sense of Obligation.
