Konrad Kleinknecht had his book 'Uncovering CP Violation - Experimental clarification in the K meson and B meson systems' published by Springer last fall. CP violation, the breaking of the symmetry between matter and antimatter, was discovered by Christenson, Cronin, Fitch and Turlay in 1964 at Brookhaven. Since 1965, high precision experiments at CERN have been performed in order to uncover the real nature of this phenomenon. After nearly 40 years, this series of CERN experiments succeeded in showing that CP violation is most likely to be due to weak flavour mixing of three families of quarks. The last step was completed by the NA31 and NA48 Collaborations over a period of 17 years. The author participated in these experiments from the very beginning in 1965. Recently CP violation has also been found in decays of neutral B mesons, in full agreement with the picture which emerged from the K decay experiments. Konrad Kleinknecht will also be able to answer questions about his long-selling textbook on 'Detectors for particle radiation', published by Cambridge University Press.
