Rough And Smooth

"Compares and contrasts common rough and smooth objects, both in nature and man-made. Includes comprehension activity"--Provided by publisher.

The rocks you see everyday can be grouped into different types, like igneous, sedimentary, or metamorphic. Some rocks are actually minerals, and you can even find fossils in some types of rocks. Complete with activities and experiments, this nonfiction science book is perfect for introducing children to geology.

Foreword by Susan Orlean A charming facsimile edition of celebrated British illustrator Lucy Dawson’s 1937 classic collection of highly detailed and loveable drawings of dogs, complete with a cloth spine and ribbon marker—the companion volume to the acclaimed Dogs As I See Them. Lucy Dawson, also known as "Mac," was a preeminent British illustrator in the 1930s and 1940s revered for her paintings and etchings of dogs, from sporting and non-sporting breeds to hounds and herders. Though she worked in numerous mediums—pencil, pen, ink, and oil—her pastels set her work apart. Noted for her commercial dog postcards and her delightful "Tailwagger" series, she also created a "Puppies" series of 40 cigarette cards during World War II—produced in a limited quantity due to wartime restrictions on paper—which have become a rare collector’s item today. One of her most famous works is her portrait of "Dookie," the British Royal Family’s favorite Corgie, which was later reproduced as a Royal Family Christmas card. Dawson also published several books, including the beloved Dogs As I See Them, and its follow-up, Dogs Rough and Smooth. Now, Dogs Rough and Smooth is available in a lovely facsimile edition for a new generation discovering her superb craftsmanship. Printed on an uncoated stock that simulates the look and feel of a sketchbook, this delightful volume is filled with her beautiful, endearing drawings of a range of breeds. The illustrations are accompanied by notes in Dawson’s own handwriting as well as a short anecdotal text that provides amusing insight into the personalities of her canine models and the experience of drawing each. A stunning reproduction of this classic work filled with full-color and black-and-white complete drawings and sketches, Dogs Rough and Smooth features a foreword by acclaimed writer Susan Orlean, and is packaged in a three-piece case with a beautiful cloth spine and long ribbon bookmark. Dogs Rough and Smooth is sure to be a collector's item treasured by dog lovers of all ages and art connoisseurs for years to come.

Provides examples and illustrations of touch, one of the five senses.

The book reviews the properties of surface plasmons that depict electromagnetic surface waves or surface plasma polaritons. Their propagation on smooth and corrugated surfaces (with rough or grating profiles) is considered. In the latter case, the corrugations can cause strong coupling of the surface plasmons with photons leading to resonances with a strong enhancement of the electromagnetic field in the surface. Coupling and field enhancement are the most prominent phenomena on corrugated surfaces and lead to numerous important applications. Attention has been focused on the explanation of the physics. To keep the text readable, sophisticated calculations have been avoided, and instead various applications dealing with enhanced light emission, nonlinear optics, SERS, and other cases of interest are discussed.

Shows differences between objects that are rough and ones that are smooth.

Soft, gooey, fluffy, prickly—textures are all around us. What clever words will you use to describe the textures pictured in this book? Jane Brocket's appealing photography and simple, whimsical text give a fresh approach to a topic all young children learn about.

Young readers learn some surface that are smooth, and some that are rough.

Explores how changing the surface of different materials changes the amount of friction they have. It contrasts objects made of smooth and rough plastic, metal, wood, and rubber.
