Dear all, Peter Knowles, a great quantum chemist working at the Cardiff University, UK http://www.cardiff.ac.uk/chemy/contactsandpeople/academicstaff/knowles-pete… and a friend of Alán's, is paying an impromptu visit to the group TODAY. We will have an informal meeting with him at 3pm today at the theory couches. Come for the quantum chemical methods, stay for the nice conversation! Best, Dmitrij
