Aperture Alike began when the author first walked into a rock-climbing gym, and soon after, a community, more than a decade ago. A community held up by friends, mentors, and unlikely prophets of the steep, which quickly presented a fantastic, intoxicating path; a lifestyle without equal. While the sensational, rugged, and itinerant chapters - from high peaks to depraved inner landscapes – of the outdoor life came together, one facet soon became clear. The inner journeys of those friends, mentors, and homely prophets far exceeded any outward feat of will. Aperture Alike attempts to shine light into the deeper realities, the inner character swings and the unplanned arcs of those who have both devoted themselves to an outside craft, and to defining themselves apart from it. Aperture Alike is a collection of short stories about community, about people pursuing their own immutably holy center point, in the midst of a life defined by trials and tribulation.

This book is intended as an advanced text for courses in antennas, with a focus on the mature but vital background field of aperture antennas. The book is aimed at final year, MSc, PhD and Post-Doctoral students, as well as readers who are moving from academia into industry, beginning careers as wireless engineers, system designers, in R&D, or for practising engineers. It assumes the reader has undertaken an earlier course of study on Maxwell's equations, fields and waves. Some of these topics are summarised in the early few chapters in order to provide continuity and background for the remaining chapters. The aperture antennas covered include the main types of horns, reflectors and arrays as well as microstrip patches, reflectarrays and lenses. To provide more than a superficial treatment of arrays, the topic of mutual coupling is covered in greater detail than most similar books in the area. Also included is an introduction to arrays on non-planar surfaces, which is of importance for applications that involve curved surfaces such as in aerodynamics or for making aperture antennas unobtrusive. A chapter is included on some modern aperture antennas to illustrate design techniques beyond the most common types of aperture antennas described in the early chapters. This is to show where advances have recently been made and where they could be improved in the future. Also included are selected topics of a practical nature for aperture antennas, namely fabrication and measurement.

The Magazine of Photography and Ideas. As the United States navigates a political moment defined by the close of the Obama era and the rise of #BlackLivesMatter activism, Aperture magazine releases "Vision & Justice," a special issue guest edited by Sarah Lewis, the distinguished author and art historian, addressing the role of photography in the African American experience. "Vision & Justice" includes a wide span of photographic projects by such luminaries as Lyle Ashton Harris, Annie Leibovitz, Sally Mann, Jamel Shabazz, Lorna Simpson, Carrie Mae Weems and Deborah Willis, as well as the brilliant voices of an emerging generation―Devin Allen, Awol Erizku, LaToya Ruby Frazier, Deana Lawson and Hank Willis Thomas, among many others. These portfolios are complemented by essays from some of the most influential voices in American culture including contributions by celebrated writers, historians, and artists such as Vince Aletti, Teju Cole, Henry Louis Gates, Jr., Margo Jefferson, Wynton Marsalis and Claudia Rankine. "Vision and Justice" features two covers. This issue comes with an image by Richard Avedon, Martin Luther King, Jr., civil rights leader, with his father, Martin Luther King, Baptist minister, and his son, Martin Luther King III, Atlanta, Georgia, March 22, 1963.

Schiff's photographs capture the shifting architectural styles and missions of the library, from the very earliest American libraries to the modernist masterpieces of Louis I. Kahn and others. The sweeping 360-degree panoramas help the viewer maintain the original vision of the architects. In the introductory essay, Manguel considers the story of the library in America, its evolving architecture and cultural role, and how the American model reflects the archetypal idea of the universal library.

A general formulation for aperture problems is given in terms of the method of moments. It applies to any two regions isolated except for coupling through the aperture. The aperture characteristics are expressed in terms of two aperture admittance matrices, one for each region. The admittance matrix for one region is independent of the other region, and hence can be used for any problem involving that region and aperture. The solution can be represented by two generalized n-port networks connected in parallel with current sources. The current sources are related to the tangential magnetic field which exists over the aperture region when the aperture is closed by an electric conductor. Explicit formulations are given for two problems, that of an aperture in a conducting plane with plane-wave excitation, and that of a waveguide feeding an aperture in a conducting plane.

In the late 1970s, the George Eastman Museum approached a group of photographers to ask for their favorite recipes and food-related photographs to go with them, in pursuit of publishing a cookbook. Playing off George Eastman's own famous recipe for lemon meringue pie, as well as former director Beaumont Newhall's love of food, the cookbook grew from the idea that photographers' talent in the darkroom must also translate into special skills in the kitchen. The recipes do not disappoint, with Robert Adams' Big Sugar Cookies, Ansel Adams' Poached Eggs in Beer, Richard Avedon's Royal Pot Roast, Imogen Cunningham's Borscht, William Eggleston's Cheese Grits Casserole, Stephen Shore's Key Lime Pie Supreme and Ed Ruscha's Cactus Omelette, to name a few. The book was never published, and the materials have remained in George Eastman Museum's collection ever since. Now, nearly 40 years later, this extensive and distinctive archive of untouched recipes and photographs is published in The Photographer's Cookbook for the first time. The book provides a time capsule of contemporary photographers of the 1970s--many before they made a name for themselves--as well as a fascinating look at how they depicted food, family and home, taking readers behind the camera and into the hearts and stomachs of some of photography's most important practitioners.
