From Tuesday 11 to Friday 14 June 2013, the international history of science conference, “One hundred years of the Bohr atom, 1913–2013”, organized by the Niels Bohr Archive, will be held at the Royal Danish Academy of Sciences and Letters in Copenhagen.  Further information — such as how to apply for attendance, as well as the preliminary programme and abstracts for the talks — may be found at http://www.nba.nbi.dk/bohratom100yrs.html.  As there are only a limited number of seats, a prompt reaction is highly recommended.
