Neville Chamberlain after a week of intense press speculation today revealed his Cabinet reshuffle. Viscount Halifax is replaced by Anthony Eden at the Foreign Office and Sir John Anderson becomes Home Secretary (unusually he is a former civil servant rather than a career politician. Halifax has taken up position as Ambassador to Atlantis. No reason has been given for the shuffle but it’s rumoured that Halifax is heading towards retirement from politics.

Rudolf Peierls and Otto Frisch, both currently based at Birmingham University, have published a paper on research undertaken at Birmingham University on chain reactions by separation of uranium element 235 from 238. Frisch and his aunt Lise Meitner have previously published a paper on the creation of barium from the collision of uranium nuclei and neutrons. Frisch and Meitner then discovered that elongation of the nucleus would allow the electrical forces to overcome the surface tension allowing the nucleus to split into two similarly sized parts. Frisch described this as “nuclear fission”, the mass of the two halves is slightly less than the original nucleus and the remainder is an output of energy produced by the split. The Danish scientist Niels Bohr discovered that the uranium fission process was due to the presence of uranium 235 which is a very rare isotope (one in 140 parts of Uranium 238 ). Bohr was unable to calculate how much uranium 235 would be needed to start a chain reaction (the splitting nuclei create neutrons which split other nuclei) and that it was impossible to occur naturally due to the rarity of uranium 235. Peirels and Frisch have now determined how much uranium 235 would be needed to begin a chain reaction, less than half a kilogram. As yet no practical use has been found although it is clear abundant power would be generated from such a chain reaction and most scientists think it will be years before any such theories can be proven and harnessed in any practical way.
