No, not in the least. You should read the first part of "The making of the atomic bomb" to get the story. What gave the push to Fermi's, Hahn's, Meittner's and many others research was the discovery of the neutron, by Chadwick (which discovery preceded any of Szilard's musings about applications). Once discovered, neutrons became the hot new toy for physicists everywhere, due to their ability to induce nuclear transmutations. So, anybody who could lay his hands on an alpha source (and these were pretty plentiful by then) was generating neutrons and bombarding anything that came to mind, to see if something interesting happens. This was the hottest topic in experimental physics in the mid and late 30s and, I'll reiterate, it had ***nothing*** to do with anything Szilard wrote. And, nobody was pursuing fission, either, just transmutations. Fission was not on anybody's mind, to the point that it went unrecognized for quite a while when it occured. That's the background to Hahn's and Meittner's work. This work, in turn, is the background to Fermi's reactor. Szilard doesn't figure in this. This is not to say that Szilard didn't play and important role but this role only began *after* fission was discovered, not before, and it was more "political" than scientific.

From the wonders of wiki: Christianity regards the Bible, a collection of canonical books in two parts, the Old Testament and the New Testament, as authoritative: written by human authors under the inspiration of the Holy Spirit and therefore the inerrant Word of God.[43] (Source 43 reads Catechism of the Catholic Church, Inspiration and Truth of Sacred Scripture (�105-108); Second Helvetic Confession, Of the Holy Scripture Being the True Word of God; Chicago Statement on Biblical Inerrancy) Despite this, Catholicism has evolved. |
