Mike Freeman - Böcker

An understanding of the fundamental principles of geometrical and physical optics is essential for any student engaged in the study of the visual sciences, but the non-physicist needs a text which clearly explains these notoriously difficult concepts in order to apply them to the practical and clinical aspects of vision. Optics by Freeman and Hull fulfils this requirement admirably.

A two-week canoe trip down the Hudson offers an opportunity to reflect on America's past, present, and uncertain future.This candid account of the author's two-week canoe trip down the Hudson River offers an introspective and humorous look at both the river and Recession-Era America. New to fatherhood and fresh from ten years in an Alaskan village, Mike Freeman sets out to relearn his country, and realizes it's in a far greater midlife crisis than he could ever be. With an eye on the Hudson's past, he addresses America's present anxieties-from race, gender, and marriage to energy, labor, and warfare-with empathy and honesty, acknowledging the difficulties surrounding each issue without succumbing to pessimism or ideology.From the river's headwaters in the Adirondacks, Freeman follows the Hudson south through America's first industrial ghost towns, where ruin begs for rebirth. Next is the Hudson Valley and the river's 153-mile estuary, with its once-teeming fisheries. Here, agriculture is redefining itself, while at West Point, officer candidates train for America's murky modern wars. The Hudson Highlands, too, are prominent, the place where Americans first wed God to nature, and where the mountains remain a potent place to mull that bond. From there it's on to Manhattan, with its skyline that symbolizes the world's financial might as well as its startling fragility.As controversial as it is comforting, Freeman's narrative makes us think in hard ways about America as the country itself drifts toward an uncertain future. But throughout, of course, is the magnificent Hudson, whose resilient beauty speaks well both to nature's toughness and America's greatest strength-the ability to redirect and change course when necessary.
