This book by Robert Weinstock was written to fill the need for a basic introduction to the calculus of variations. Simply and easily written, with an emphasis on the applications of this calculus, it has long been a standard reference of physicists, engineers, and applied mathematicians. The author begins slowly, introducing the reader to the calculus of variations, and supplying lists of essential formulae and derivations. Later chapters cover isoperimetric problems, geometrical optics, Fermat's principle, dynamics of particles, the Sturm-Liouville eigenvalue-eigenfunction problem, the theory of elasticity, quantum mechanics, and electrostatics. Each chapter ends with a series of exercises which should prove very useful in determining whether the material in that chapter has been thoroughly grasped.The clarity of exposition makes this book easily accessible to anyone who has mastered first-year calculus with some exposure to ordinary differential equations. Physicists and engineers who find variational methods evasive at times will find this book particularly helpful.
"I regard this as a very useful book which I shall refer to frequently in the future." J. L. Synge, Bulletin of the American Mathematical Society.

Every cologne certainly lasts differently….. just be aware
Scent: Original Citrus + Eucalyptus
Smells very nice like Harry’s Shower jell but doesn’t last very long at all on me , hopefully others so definitely not worth the money as far as I’m concerned

A well-rhymed book of poems
Format: Paperback
Thomas Hardy is a superb poet, a master rhymer, one of the main features of his poetry. These poems here are well-written and a delight to read. It is quite amazing to think why his poetry was so ignored and for the most part did not get much attention in his lifetime after one finishes reading the book. It tells more about the ignorance of man than Hardy as a poet that in some ways is getting the praise that he so much deserves, finally.
Numerous are the poems that show mastery of diction and subject matter. They are carefully crafted to make them a jewel of poetry. Read them for what they bring which is magnificent poetry seen in their lines.

A Great Novelist's Wonderfully Liberating Indulgences with Poetry
Format: Paperback
While a prolific novelist, Thomas Hardy is a first-rate poet whose verse seems to get lost between attempts at poet canonization among those between late-Victorianism and early Modernism. Perhaps this narrow way of looking at the history of poetry is why Hardy's legacy as a poet is often overlooked. He doesn't neatly fit in with categories like realism, symbolism, naturalism, aestheticism, modernism, etc., because he grapples with both major and minor themes addressed and techniques used by the big names of the numerous movements that were ending, beginning, or in their prime state at the turn of the century. It's very interesting how his poems shine a light on his expertly crafted novels (especially the more provincial narratives), but I get the impression that Hardy viewed his identity as prose and verse stylist as separate personal facets. Such a self-evaluation is almost unfair to him. While undoubtedly what we might call a formalist novelist in the vein of Flaubert--one with intense philosophical interests like Austen (and Dostoevsky for a non-English example)--the formalism and philosophical bend certainly appears in his poetry, and Hardy almost seems like a freer artist when you read his verse works. This great collection proves to be curiously wonderful and will appeal to poetry lovers, Hardy enthusiasts, students and scholars of the many different art movements of the late 19th and early 20th centuries, and those of readers with a deeply philosophical approach to reading. That said, he's wonderfully and surprisingly accessible to laypeople as well, though always provides a great challenge to his readers without pretension or esoteric persuasions (if that's a factor that you might find frustrating in poetry).

Beautiful
Format: Paperback, Format: Paperback
Beautiful book—arrived in great shape! And I absolutely adore Hardy’s poetry. Not sure why I can never find him on the poetry shelves of my bookstores, because he’s one of the greats. So far my favorite is “Her Death and After”. Sounds morose, but it’s actually quite beautiful. It will touch your heart—just what Thomas Hardy had a knack for. If you like classic poetry, please get this book. It’s great!
