Hi. I want to show a publication from the middle of the 20th century. http://rsta.royalsocietypublishing.org/content/253/1025/205 I have been surprised by the subject it deals with. I would like to understand why the Royal Society digitizes that old document, which has never been received by the mainstream. I suppose that the lack of reception is a consequence of serious errors in development. And I would like to have some idea of those errors, if they exist. Your comments on this will surely help me. Best regards.
