Through the frame of Zoom, this collection of essays examines the rapid emergence of videoconferencing in everyday life under COVID-19, its preexisting performative logic, and the ongoing implication of these practices for millions of individuals and institutions. The year 2023 marked the end of the World Health Organization's classification of the COVID-19 outbreak as a “public health emergency of international concern,” yet many of the organizational and institutional restructurings that occurred in the rapid response to the pandemic have remained firmly in place. The prevalence of videoconferencing in everyday life marks one such instance, not only highlighting the dramatic social and cultural transformations that occurred during a period of lockdowns, social distancing, and stay-at-home orders, but also serving as an index of all that has emerged as the “new normal” since March 2020. Overnight, it seemed, Zoom emerged as the default videoconferencing platform, rapidly morphing from brand name to eponymous generic. While this volume focuses predominantly on Zoom and its place in the collective imagination and daily practice of those of us whose lives are profoundly caught up in digital networks, many of these insights presented here apply to other videoconferencing platforms as well, and a supporting logic that has governed neoliberal lives since long before the first lockdowns began. The twelve chapters in this collection explore how videoconferencing platforms in general, and Zoom in particular, have provided individuals and institutions new modes of “engagement,” while at the same time reifying, normalizing, and domesticating modes of surveillance, control, and marginalization that have been part and parcel of a networked-based performative logic for nearly a century.

At the intersection of science, art, and design, this must-have coffee table book highlights 100 mind-blowing colors that you’ve likely never seen before. From Instagram sensation and self-described "mad scientist artist" Tyler Thrasher and creator of the popular Matter subscription box Terry Mudge, this book comes with a foreword by Hank Green. This gorgeous compendium contains 100 amazing colors that you might otherwise live your whole life unaware of. These colors exist in the strangest of places, and serve extremely specific functions in nature, or were human-made with one goal in mind. In this oversized, design-forward book you'll find entries for each of the 100 colors, organized in gradient order, with structural and impossible colors set at the end. Each entry has a 2-page spread with a full-page image of the color plus snappy descriptions, and easy-to-understand category symbols. Some entries include diagrams. Even includes structural colors and colors outside the range of human visibility! Also included is a brief introduction to color theory, a myth-busting section, plus index, glossary, and notes. Here is your universe in living color: Cosmic Latte: The average color of the universe. Dragon’s Blood: A tropical tree that bleeds red resin with incredible medicinal potential. Sonoluminescence: A color created by sound! Eigengrau: The color we perceive in the absence of light (and no, it's not "pitch black"). Perfect for anyone who loves science or art, and bursting with astonishing facts and stunning photography, The Universe in 100 Colors is a wonder for the senses.

The present volume covers the physiology of the visual system beyond the optic nerve. It is a continuation of the two preceding parts on the photochemistry and the physiology of the eye, and forms a bridge from them to the fourth part on visual psychophysics. These fields have all developed as independent speciali ties and need integrating with each other. The processing of visual information in the brain cannot be understood without some knowledge of the preceding mechanisms in the photoreceptor organs. There are two fundamental reasons, ontogenetic and functional, why this is so: 1) the retina of the vertebrate eye has developed from a specialized part of the brain; 2) in processing their data the eyes follow physiological principles similar to the visual brain centres. Peripheral and central functions should also be discussed in context with their final synthesis in subjective experience, i. e. visual perception. Microphysiology and ultramicroscopy have brought new insights into the neuronal basis of vision. These investigations began in the periphery: HARTLINE'S pioneering experiments on single visual elements of Limulus in 1932 started a successful period of neuronal recordings which ascended from the retina to the highest centres in the visual brain. In the last two decades modern electron microscopic techniques and photochemical investigations of single photoreceptors further contributed to vision research.

Robin Sloan expands the Penumbraverse to new reaches of time and space in a rollicking far-future adventure. In Moonbound, Robin Sloan has written a novel with the full scope and ambitious imagination of the very books that lit the engines of Mr. Penumbra’s 24-Hour Bookstore: an epic quest as only Sloan could conceive it, mixing science fiction, fantasy, good old-fashioned literary storytelling, and unrivaled enthusiasm for what’s next. It is eleven thousand years from now . . . A lot has happened, and yet a lot is still very familiar. Ariel is a boy in a small town under a wizard’s rule. Like many adventurers before him, Ariel is called to explore a world full of unimaginable glories and challenges: unknown enemies, a mission to save the world, a girl. Here, as they say, be dragons. But none of this happens before Ariel comes across an artifact from an earlier civilization, a sentient, record-keeping artificial intelligence that carries with it the perspective of the whole of human history—and becomes both Ariel’s greatest ally and the narrator of our story. Moonbound is an adventure into the richest depths of Story itself. It is a deeply satisfying epic of ancient scale, blasted through the imaginative prism one of our most forward-thinking writers. And this is only the beginning.
