This memoir develops, discusses and compares a range of commutative and non-commutative invariants defined for projection method tilings and point patterns. The projection method refers to patterns, particularly the quasiperiodic patterns, constructed by the projection of a strip of a high dimensional integer lattice to a smaller dimensional Euclidean space. In the first half of the memoir the acceptance domain is very general - any compact set which is the closure of its interior - while in the second half we concentrate on the so-called canonical patterns. The topological invariants used are various forms of $K$-theory and cohomology applied to a variety of both $C*$-algebras and dynamical systems derived from such a pattern.The invariants considered all aim to capture geometric properties of the original patterns, such as quasiperiodicity or self-similarity, but one of the main motivations is also to provide an accessible approach to the the $K0$ group of the algebra of observables associated to a quasicrystal with atoms arranged on such a pattern. The main results provide complete descriptions of the (unordered) $K$-theory and cohomology of codimension 1 projection patterns, formulae for these invariants for codimension 2 and 3 canonical projection patterns, general methods for higher codimension patterns and a closed formula for the Euler characteristic of arbitrary canonical projection patterns.Computations are made for the Ammann-Kramer tiling. Also included are qualitative descriptions of these invariants for generic canonical projection patterns. Further results include an obstruction to a tiling arising as a substitution and an obstruction to a substitution pattern arising as a projection. One corollary is that, generically, projection patterns cannot be derived via substitution systems.

The Great War will always be synonymous with trench warfare and the mass slaughter inflicted by machine guns on the helpless but gallant infantry. There is a good reason for this view as the machine guns took a terrible toll, and the infantry’s experiences continue to fascinate and appal people today. But one aspect of the fighting that gets insufficient attention is the artillery. Histories of the major battles often reduce the role of the big guns to a few paragraphs, and this has created a seriously distorted impression of the reality of the fighting. A better balance needs to be struck, and that is the intention of John Hutton’s new book on the gunners of 1914. He tells the story of the war as the gunners themselves saw it, focusing on the first few months of warfare which were fundamental to the conduct of the campaign. The gunners may not have always shared the trench experiences of the infantry in the front line, but they were in the thick of the action, and success or failure depended on them. The personal testimonies of those who served with and supported the guns provide a vital insight into the colossal tragedy and drama of the war from the artilleryman’s point of view.

The great retreat of the British Expeditionary Force from Mons in August 1914 is one of the most famous in military history, and it is justly celebrated. But not all the British soldiers who were forced back by the German offensive performed well. Two colonels, Elkington and Mainwaring, tried to surrender rather than fight on, and were disgraced. This is their story. In this compelling account John Hutton shows, in graphic detail, the full confusion of the retreat, and the dire mental state to which brave men can be reduced by extreme stress, uncertainty and fatigue. But he also describes how Elkington redeemed himself. He joined the French Foreign Legion, fought gallantly, was severely wounded and was reinstated by King George V. His is one of the more remarkable stories to come out of the Great War, as is the story of the attempted surrender at St. Quentin itself.
