A History of St Catharine's College, Cambridge, by W. H. S. Jones, was originally published in 1936. The book documents the history of the college, which was founded in 1473 by Robert Woodlark, then the Provost of King's College. It is thought the name was chosen in honour of Catharine of France, the mother of King Henry VI, although it is also possible that it was named as part of the Renaissance cult of St Catharine, a patron saint of learning. The book charts the history of the college from the foundation to the 1930s, and is divided into chapters on topics including domestic history, key figures, and a section on documents, including statutes, income, authorities and correspondence. The book is generally acknowledged to be the authoritative text on St Catharine's College and will appeal to anyone interested in the University of Cambridge.

This thesis focuses on searches for squarks with the ATLAS detector in "compressed" scenarios where the scalar top is very close in mass to the lightest supersymmetric particle. These models are theoretically appealing because the presence of a quasi-degenerate scalar top enhances the self-annihilation cross-section of the lightest supersymmetric particle, acting therefore as a regulator of the dark matter relic density. Two main analyses are presented: the first is a search for scalar tops decaying to charm quarks. The identification of jets originating from the charm quark is very challenging due to its short lifetime. The calibration of tools for charm-tagging has paved the way to measuring the decay of the Higgs boson to pairs of charm quarks. The second analysis presented is the development of a novel technique for reconstructing low momentum b-hadrons. This tool has enabled the ATLAS collaboration to explore topologies that were previously inaccessible.
