  1. ISOLDE Nuclear Reaction and Nuclear Structure Course 22-25 April 2014 Nuclear Reaction at Intermediate to Relativistic Energies: what data tell us (I)

  2. I do not know much about anything;what I know is already commonplace.Wouldn’t it be nice to know just one fact,for example the proportions of the spots of the ladybird. Jeg kender ikke meget til meget;det jeg kender til er i forvejen meget udbredt.Tœnk at vide bare een bestemt ting,for eksempel forholdet mellem mariehønens pletter. Benny Andersen, Viden 1965
