At some point in their careers, most physicists make an attempt to read and understand Newton's Principia. Unfortunately, it is an extremely difficult book.It quickly becomes clear that one does not simply 'read' the Principia, even for a professional physicist Newton's prose, written in Latin and translated to English, is difficult to follow. His diagrams and figures are complicated and confusing. To understand fully what Newton had done, the problems he posed would have to be solved by the reader.Newton's geometric methods and techniques, and the geometry and vocabulary that passed for common knowledge in the late 17th century, are now arcane, and all but inaccessible to a modern reader. The contents of the Principia are not. Most physicists and physics students, and many scientists in general, would find the physics in the Principia interesting, illuminating, and useful.This book presents all the wonderful physics in the Principia in a manner that a modern reader can recognize and understand using physics and mathematics as we understand them in the 21st century.

Oysters are a narrative food: in each shuck and slurp, an eater tastes the place where the animal was raised. But that's just the beginning. Andre Joseph Gallant uses the bivalve as a jumping off point to tell the story of a changing southeastern coast, the bounty within its waters, and what the future may hold for the area and its fishers. With A High Low Tide he places Georgia, as well as the South, in the national conversation about aquaculture, addressing its potential as well as its challenges. The Georgia oyster industry dominated in the field of oysters for canning until it was slowed by environmental and economic shifts. To build it back and to make the Georgia oyster competitive on the national stage, a bit of scientific cosmetic work must be done, performed through aquaculture. The business of oyster farming combines physical labor and science, creating an atmosphere where disparate groups must work together to ensure its future. Employing months of field research in coastal waters and countless hours interviewing scholars and fishermen, Gallant documents both the hiccups and the successes that occur when university researchers work alongside blue-collar laborers on a shared obsession. The dawn of aquaculture in Georgia promises a sea change in the livelihoods of wild-harvest shellfishermen, should they choose to adapt to new methods. Gallant documents how these traditional harvesters are affected by innovation and uncertain tides and asks how threatened they really are.
