This book provides an incisive, self-contained introduction to one of the most intriguing subjects in modern physics, presenting the evidence we have from astrophysics for the existence of dark matter, the theories for what it could be, and the cutting-edge experimental and observational methods for testing them.

It begins with a survey of the astrophysical phenomena, from rotation curves to lensing and cosmological structure formation.

The book explains the constraints on each theory, such as direct detection and indirect astrophysical limits.

New York City witnessed unparalleled growth in the first half of the 19th century, its population rising from thirty thousand to nearly a million in a matter of decades.

“Feeding Gotham” looks at how America’s first metropolis grappled with the challenge of provisioning its inhabitants. It tells the story of how access to food, once a public good, became a private matter left to free and unregulated markets—and of the profound consequences this had for American living standards and urban development. 

Taking readers from the early republic to the Civil War, Gergely Baics explores the changing dynamics of urban government, market forces, and the built environment that defined New Yorkers’ experiences of supplying their households.

A masterful blend of economic, social, and geographic history, “Feeding Gotham” traces how a highly fragmented geography of food access became a defining and enduring feature of the American city.
