  • “Relativity” and “Quantum” in the Titles and Abstracts of “Physical Review” Papers, 1911-2007

    JF Ptak Science Books  Quick Post 

    Here’s a simple list I made using a search tool on the American Physical Society site showing the frequency of the appearances of the words “relativity” and “quantum” in the titles and abstracts of papers that appeared in the Physical Review from 1911-2007. (I made this in 2008 so that’s why the count stops there.) This may be interested to graph out, though the info might not really tell you anything beyond he obvious.  Interestingly, RC Tolman seems to have the first article in PR on relativity (1910) and the second on quantum mechanics (1917).  Or so it seems at this point…

    PR articles with the word “relativity” in the title or abstract:

    2007 (1,012)
    2006 (971)
    2005 (968)
    2002 (846)

  • History of the Past and History of the Future: Communications and Electronics in the Year 2012 (from 1962)

    JF Ptak Science Books    Post 2803 (Reference Tools Post) 

    Now HERE’S a wonderful and referenced and deep look at the history and future of electronics, and one that I believe is very overlooked. The article has the slightly opaque title of “Proceedings of the IRE Fiftieth Anniversary, 1912-1962” , which is the entire May issue for the journal, a double-brick of a book, weighing in at 6 pounds and running over 900 pages. It is a vast and compelling survey of the history and present state and future of electronics in general, boasting an authorship of leading lights across many different fields and encompassing 250 articles. (Some of the big names include: Terman, H.A. Wheeler, H. Olson, Gordon Teal, Presper Eckert, Zworykin, Simon Ramo, JR Pierce, Watson-Watt, Jerome Wiesner, Leo Beranek, Belevitch, Colin Cherry, Lee Lusted, Ronald “THE Antenna”) King, and many others. There’s fantastic reporting on the present-day state of things, as well as dozens of provocative and very prescient overview of what the future may/will bring…and take.

    I obviously can’t reproduce the volume, and no one seems to have the whole thing online, but I can provide a mostly-cleaned-up OCR (please pardon some of the typos) of the three very packed pages of the table of contents of the issue—many of those individual articles can be found online. (If anyone wants the original of this work, I have it for sale in my bookstore.) Perhaps now that you know such articles exist and hadn’t before, you may be able to put this list to some use.

    Some interesting articles include: There Will Be No Electronics Industry in 2012 A.D., J. M. Bridges; Communications Throughout the Solar System, W. H. Pickering; The Information Science anti Industry Fifty Years Hence, Robert M. Bowie; Machines with Imagination, G. A. Morton; The Integration of Man and Machine, J. Presper Eckert, Jr; Man-Machine Coupling-2012 A.D., R. M. Page…well, you get the idea.

  • Life Expectancy–a Useful Collection of Numbers

    JF Ptak Science Books  Quick Post/Reference Post

    I was having an interesting conversation with my friend, Andy Moursund, who asked if we are better off now or 50/60 years ago. That was the basic premise from which MANY qualifications were made, including who “we” are, where that “we” is, what they do, and so on, and then followed by defining “better” in a number of different ways, and then creating relative measures and measurements, and etc. It is a very complicated question–Andy says it is his favorite question for a long car ride with someone, and I like it. Anyway, in checking out one point I needed to consult numbers for human life expectancy, and since it took a little poking around, I thought I’d collect a useful selection of them and share it here.

  • A New-to-Me Find: the History of Nobel Prize Nominations

    JF Ptak Science Books   Quick Post

    Yesterday I found a fine resource that lives within another fine resource—somehow I missed it, entirely, and for years I suspect of using the one without noticing the other.

    The new-to-me find is the history of nomination process for the Nobel Prize on the Nobel Prize site. What this searchable database holds are all those nominated for the prize in all of the Academy’s fields, who nominated whom, what year, and for what area, with biographical links for all involved, an then cross-referenced so you can search by year and name.

    • Nobel Prize Nomination Archive:  https://www.nobelprize.org/nomination/redirector/?redir=archive
    • Nobel Prize site: https://www.nobelprize.org/

    I came upon the site looking to see the proof of nomination of Gustave Le Bon for the Physics Award in 1903–and indeed, he was there.  I’m not very sure about what Le Bon had done to achieve this level of recognition as he seems in his polymathic way to be around the peripheries of a lot of interesting things in a number of different fields without being at the core (?)–but there he was. One nomination for that year and then for all time. He didn’t stand a chance for the prize for that year, with Becquerel and Poincare receiving it for 1903.

    I didn’t check to see how many others received one and only one nomination, though I did find who received the most nominations and never receive the award–that distinction belongs to the great Arnold Sommerfeld, who was one of the last of those people who “knew everything”, and who over the years received 184 nominations. (#2 by the way was microbiologist Gaston Ramon with 155.)

    Just for the fun of it I looked up Richard Feynman and found that he was nominated 48 times, receiving multiple votes in 1956, 1957, 1960, 1962, 1963, 1954, and finally 1965 when we was awarded the prize. Einstein received 62 nominations between 1922 and 1922, receiving them in every year but 1911 and 1915–he was finally awarded the prize (for 1921) in 1922. 

    The story of Einstein’s Nobel (that, is, the getting-it and not-getting-it part) is a bit complex, but is fabulously told by Abraham Pais in his paper “How Einstein Got the Nobel Prize: Why did the Nobel Committee for Physics wait so long before giving Einstein the Prize, and why did they not award it for relativity?” found in  American Scientist, Vol. 70, No. 4 (July-August 1982), pp. 358-365 (and also in a section of his book Einstein Lived Here).  Suffice to say here that the seemingly very long time for him not to receive the award (that he ultimately was given in 1922 for the photoelectric effect and not for relativity) is a “story which has neither heroes nor culprits” according to Pais, but rather seems one where the delayed recognition was due to very conservative appreciation for the proofs of the work. 

    Here’s a table from the Pais paper outlining the history of the Einstein nominations:

    Einstein nobel historyAgain, Pais points out that the Academy warded Einstein the prize for the photoelectric effect, and not for relativity. We can see in the graph below from the Lecat bibliography of relativity (published 1925) that there was an enormous increase in publications on the theory beginning at the end of WWI. Then came the experimental verification in 1919 that made Einstein into Einstein. Of course this is just a quantitative display of the numbers of papers published on the subject for that year–the members of the Academy certainly had some reservation on the theory of relativity even into 1920, citing what Pais refers to as not-unreasonable hesitations on the interpretation of the eclipse data.

    In any event, it was a very interesting and somewhat shocking experience to find the nomination archive. I recommend a tour.

  • Quantum Mechanics Bibliographic Timeline–the El’yashevich List

    This is a handy and interesting timeline of QM placed in chronological order from the article by M A El’yashevich  ( “From the origin of quantum concepts to the establishment of quantum mechanics”, by M A El’yashevich, in Soviet Physics USPEKHI, 1977, 20 (8), 656–682.). I did not compose this nor did I add to it in any way—this is the sole effort of Prof. El’yashevich. I did make some slight compositional changes to make the list a little more accessible and usable to people like me, and condensed the list to only 1950 (whereas in the original the entries extend into the 1970’s), and made so that each entry is limited to a line or two;  but that’s it.

    I guess it would be easy to start the list with Planck if you wanted to give it a firm footing somewhere, though the history of quantum mechanics goes into development stages long before the 1900 Planck paper.  Be that as it may, this is just a quick exercise, and if an idea was formed or a lost memory found via a quick look at this list, then it is good enough for me.

  • A Great Classic–the First True Textbook on Computing Bibliography!

    JF Ptak Science Books   Post 2529    Reference Tools series

     C.B. Tompkins’  High-Speed Computing Devices (New York,  McGraw Hill, 1950) is probably the best of the pre-1960 textbooks on the computer, complete with stout bibliographies and lots of bits to trail  from the golden age of computers. This classic work is enhanced by a (very) unusually complete series of chapter-ending references and bibliographies. Among much else of interest we find a treatment of the Harvard Mark I and II on pp 183-187 in the chapter on “Large-Scale Digital Computing Systems” on pp 182-222 with bibliography occupying pp 218-222. Also, the “Punched-Card Computing Systems” chapter pp 146-181 has a very nice bibliography on pp 166-181. 

    Books--era

     

    Even though I’ve used this book quite a bit I’ve never collected the chapter-ending references in one document until today. Tompkins now appears in the glorious Internet Archive, and I’ve taken the 16 pieces of bibliography and gathered them all below in a document that is about 40 pages long.  Have a look, and enjoy–thanks to the Internet Archive!

    • This is considered to be the first textbook on digital computers, the first compendium in English on digital computer technology, and a pioneering work that influenced many computer designers during the 1950s. It provides an unsurpassed picture of the state of the art during the late 1940s, and is further enhanced by the inclusion of several excellent bibliographies. — Sarrazin F2.
    • “The book is a careful analysis of the electronic field as of 1950 and was in very large measure written by the late Professor C. B. Tompkins..” – Goldstine 315.
    • (This book) was written to satisfy “a perceived need, following the end of WW II, for compendium of technologies applicable to the emerging field of electronic digital computers…Because published technical information was scarce in the U.S., there can be little question that the book was an important contribution to computer literature…with its state of the art picture of the period 1947 through 1949, establishes a well-documented baseline fro tracking and evaluating subsequent technological progress.”– Arnold Cohen, from the Introduction to the 1983 Charles Babbage Institute Reprint Series Edition of the ERA Report, published by Tomash Publshing.

  • Stephens Bibliography on Nuclear Fission (1948)

    JF Ptak Science Books    Reference Tools series

    Stephens nuclearHere’s a very useful tool for the early days of nuclear fission and atomic energy–the bibliography from William Stephen’s Nuclear Fission and Atomic Energy (published by the Science Press in 1948). The OCR is a little unsteady but the info is there even if it isn’t as clear as it might be.  

    The full text for the work is found at the Internet Archive, here:  https://archive.org/details/nuclearfissionan030064mnb

    Also see the excellent Louis Turner bibliography for nuclear fission, 1934-1940 (133 items) in an earlier post on this blog, here:  https://historyofideasblog.com/thesciencebookstore/2013/08/turners-bibliographic-review-of-nuclear-fission-1934-1940.html

  • A Very Early Bibliography on the Theory of Special Relativity (1910)

    JF Ptak Science Books    Reference Tool series

    Jakob Laub–the first collaborator of Albert Einstein–wrote one of the earliest histories/retrospectives of relativity theory for the Jahrbuch der Radioaktivitat und Electronik in volume 7 for 1910: “Uber die experimentellen Grundlagen des Relativitatsprinzips”, pp 405-463. (It seems that I don’t often see/notice references on this level citing the first German edition of an integral work in another language, which Laub does here for example in two articles by Fizeau that he found in Annalen when their original publication took place in the Comptes Rendus.)  (See the reference for Laub in Physics Before and After Einstein  edited by M. Mamone Cap; also The Scientist as Philosopher: Philosophical Consequences of Great Scientific ...by F. Weinert. 

    This paper also contains a 127-item bibliography, which I cannot find online and which I reproduce below.

    On Laub, from the Dictionary of Scientific Biography, volume 17:

    “Laub attended gymnasium in Rzeszόw. In 1902, after studying briefly at the universities of Cracow and Vienna, he entered the University of Göttingen as a student of mathematics and physics. There, taking courses and seminars with David Hilbert and Hermann Minkowski, he became interested in the electron theory. He turned to experiment, and in 1905 he decided to work with Wilhelm Wien at Würzburg. Laub’s doctoral dissertation (1907) concerned secondary cathode-ray emission. At his oral defense (1906), he introduced Einstein’s special theory of relativity, which Wien had recommended to him in September 1905. For the next several years Laub remained at Würzburg and concentrated on extending Einstein’s ideas.”

    “Although by early 1908 Einstein was attracting notice from distinguished physicists, he had not yet received a university appointment. It was an unusual step, then, when in February 1908 Laub wrote to Einstein to ask if he could visit Bern to study relativity with him. Laub became Einstein’s first scientific collaborator. Together they published articles criticizing Minkowski’s notion of electromagnetic force and suggesting an experiment to decide between Einstein’s special relativity and Hendrik Lorentz’s electron theory.”
