Functional programming is rooted in lambda calculus, which constitutes the world's smallest programming language. This well-respected text offers an accessible introduction to functional programming concepts and techniques for students of mathematics and computer science. The treatment is as nontechnical as possible, and it assumes no prior knowledge of mathematics or functional programming. Cogent examples illuminate the central ideas, and numerous exercises appear throughout the text, of...

Nobody doubted that atoms were real once atomic energy was developed, but in the early 20th-century and before their existence was widely doubted. Defending Materialism follows the political and theoretical background of this intense philosophical controversy, defending atomistic and mechanical materialism against idealist paradigms. These accounts range from the explicit idealism criticised by Lenin and Einstein to the implicit Hegelian idealism that inf...

A survey vessel trawls up a man's body in the Outer Hebrides and ship's engineer Helen finds a compelling green stone in his pocket. On Rannoch Moor, her cousin Malcolm, a local ranger, is visited by a strange woman. She goes missing, and he too finds a green stone. The cousins have stumbled upon a multi-faceted conspiracy involving the high-tech company Fundamantal Forces who are promising limitless green energy from under the moor. It's soon clear that deeper, perhaps darker forces are a...
