    Robert Oppenheimer was born on 22 April 1904 in New
    York. His father, who had come to the United States from
    Germany at the age of 17, was a prosperous textile importer. By inheritance, Robert was well-to-do all his life.
    The father was quite active in many community affairs, and
    much interested in art and music. He had a good collection of paintings, including three Van Goghs.
    Oppenheimer’s mother, Ella Freedman, came from Baltimore. She was a painter who had studied in Paris, and was
    a very sensitive person. Robert had one younger brother,
    Frank, who also became a physicist; he is Professor of Experimental Physics at the University of Colorado, Boulder,
    Colo. Oppenheimer had close ties both with his parents
    and his brother....continues.

    PRINTED EDITIONS This book is part of a 2-volume set. The other volume in the set is: An Anthology of Global Risk


    This innovative and comprehensive collection of essays explores the biggest threats facing humanity in the 21st century; threats that cannot be contained or controlled and that have the potential to bring about human extinction and civilization collapse. Bringing together experts from many disciplines, it provides an accessible survey of what we know about these threats, how we can understand them better, and most importantly what can be done to manage them effectively.



    These essays pair insights from decades of research and activism around global risk with the latest academic findings from the emerging field of Existential Risk Studies. Voicing the work of world leading experts and tackling a variety of vital issues, they weigh up the demands of natural systems with political pressures and technological advances to build an empowering vision of how we can safeguard humanity’s long-term future.



    The book covers both a comprehensive survey of how to study and manage global risks with in-depth discussion of core risk drivers: including environmental breakdown, novel technologies, global scale natural disasters, and nuclear threats. The Era of Global Risk offers a thorough analysis of the most serious dangers to humanity.



    Inspiring, accessible, and essential reading for both students of global risk and those committed to its mitigation, this book poses one critical question: how can we make sense of this era of global risk and move beyond it to an era of global safety?

  • Handbook of Cavitation Erosion

    Alagu Thiruvendagam

    Prepared for Office of Naval Research

    January 1974 (21MB, 320 pages)

    https://apps.dtic.mil/sti/pdfs/AD0787073.pdf


    Useful old-school reference document (text is ok, but diagrams are a bit unclear).

    Note that this kind of work influenced a lot of the thinking around cavitation damage for many decades. The theories tended to involve inertial impact and material stress, and nothing else. This reflected a typical silo approach to research, where cavitation was seen solely as a mechanical problem, and so potential chemical effects, and possible local plasma generation, tended not to be considered.


    Edit: Alagu Thiruvendagam has a ResearchGate page. After his cavitation work, he moved onto a totally different area of research, but he has many of his old documents available for dowlnoad.

  • Here is a brand new publication for those who like a lot of equations.


    RA-DIANT - Next Generation Renewable Energy Device


    Even though the name is given above, the publication handles Maxwell-equations by utilising Clifford algebra.

    I'm not the smartest guy in mathematics, but maybe because of that I paid more attention to the written text.

    That's why I noticed this interesting conclusion at p. 137:


    "Since the last term of equation [18.53] is a sextvector, even the 5D spacetime is not

    sufficient and it is necessary to work with 7D spacetime to get closer to the true nature of

    reality."


    Please have fun ;) with the publication.

  • I recommend this book. It is not about cold fusion per se, but you can learn a lot about cold fusion from it:


    Cardwell, Donald. Wheels, Clocks, and Rockets: A History of Technology (Norton History of Science) (p. 498). W. W. Norton & Company. Kindle Edition.


    Here is an interesting quote from the book, p. 498 Kindle edition. This shows how important cold fusion researchers are. I think it also shows that while academic papers are important, hands-on cooperation in the lab is essential.



    . . . The industry will have a corresponding professional institution and journal. In outline the same principle can be traced back to the medieval guilds. Such a system does not inhibit, in fact it may well encourage, evolutionary improvement but it may – and for familiar reasons – resist radical innovation for which there will be few or no precedents and which, as we saw, tends to be brought about by individuals from outside the industry or technology. The objection, then, is that a strictly evolutionary history of technology would obscure this, surely important, feature of the processes of invention and innovation. Furthermore, with a revolutionary invention a new language and a new vocabulary have often to be created, and ‘new men’ appear – much to the bewilderment and often the disapproval of the older generation. How many stagecoach drivers, for example, could have understood the terms used by locomotive engineers in 1831? Older people are baffled by the language of computing; their children take to it easily.


    A second objection is ad hominem. The historian in his or her study can easily describe the early history of the steam engine as an evolutionary process, beginning with imaginative speculators such as Branca, de Caus, the Earl of Worcester and going on to include von Guericke, Hautefeuille, Huygens, Papin and then Savery, before Newcomen rounds off the story with his successful engine of 1712. However, our experiences in building and operating an exact replica of the 1712 engine (at one third scale it stands five metres high) has convinced us of the original genius of Newcomen, a real hero-engineer. Problems, not mentioned in any of the literature, were met and overcome; the true functions of the key components were fully understood and their relationship to the operation of the engine appreciated. . . . Much has already been learned that is not to be found in the written records. It follows that any levelling down of technological achievement, and with it of the hero-engineer, must tend to obscure key features of the process and make difficult any objective evaluation of individual cases. A final lesson is that there is great scope for practical experimentation to supplement (and correct) history based solely on documentary evidence. In addition to these specific objections, there is the general point that, the course of political history being determined, at least in part, by statesmen, kings, conquerors and prelates, the reader will expect to find analogous figures in the course of the history of technology. That expectation should be met. A history without notable figures, without major episodes and in which all is ascribed to social action, would be an unsatisfactory and, in the last resort, a sterile affair.
