Against the pomp and pageantry of turbulent seventeenth century England, Elizabeth Goudge weaves the poignant tale of Lucy Walter, the proud and beautiful secret wife of Charles II. From her early childhood in a castle by the sea in Wales and the joys and pangs of childhood, to her tragic estrangement from the king and her death in Paris at the age of twenty-eight, Lucy Walter lived to the full a life of intense joy and equally intense drama. Miss Goudge portrays brilliantly a young love almost too ecstatic to bear. Equally moving is her characterization of Lucy—a spirited woman caught up in the cataclysmic wars and disruptive revolution of a tumultuous era. From London at the time of the Great Fire, to Paris when British royalty fled to the sanctuary of the Louvre, to Brussels and The Hague and a rich panoramic background—a master storyteller traces the life and loves of an extraordinary woman. The Child from the Sea is a superbly colorful and romantic historical novel alive with brilliant cameos and infused with a spiritual essence rare in our times.

Gruffudd ap Llywelyn was Wales' greatest king. Ambitious and battle-sure, he succeeded in doing what no Welsh king before him was capable of: he ruled all Wales as a united and independent state. He went further by turning the Viking threat to his realm into a powerful weapon and conquering border land that had been in English hands for centuries. Having emerged as a war leader, Gruffudd also proved to be much more: a patron of the arts and church, with the trappings of a king who was respected and feared on the European stage. His eventual murder at the hands of his own men narrowed the country's political ambitions and left Wales in chaos on the eve of the arrival of the Normans. Those who betrayed Gruffudd were the forebears of the famous princes who would dominate Wales until the Edwardian Conquest, meaning that the former king left no one to tell of his glory. As a result, 1,000 years after his birth, the would-be nation builder is all but forgotten. Here, Sean and Michael Davies reveal the king in all his glory, telling for the first time the story of one of Wales' greatest figures and exploring the full implications of Gruffudd's rule. For, without Gruffudd, the fate of King Harold and the outcome of the Battle of Hastings would have been very different...

The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self-contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.
