This book offers the first in-depth investigation into the relationship between the National Birth Control Association, later the Family Planning Association, and contraceptive science and technology in the pre-Pill era. It explores the Association's role in designing and supporting scientific research, employment of scientists, engagement with manufacturers and pharmaceutical companies, and use of its facilities, patients, staff, medical, scientific, and political networks to standardise and guarantee contraceptive technology it prescribed and produced. By taking a micro-history approach to the archives of the Association, this book highlights the importance of this organisation to the history of science, technology, and medicine in twentieth-century Britain. It examines the Association's participation within Western family planning networks, working particularly closely with its American counterparts to develop chemical and biological means of testing contraception for efficacy, quality, and safety.

A brilliant new voice in science writing shows why playfulness and curiosity are the key to science.

Why would anyone research how elephants pee? Or study worms who tie themselves into a communal knot? Or quantify the squishability of a cockroach? It all sounds pointless, silly, or even disgusting.

Maybe it is. But in The Salmon Cannon and the Levitating Frog, Carly Anne York shows how unappreciated, overlooked, and simply curiosity-driven science has led to breakthroughs big and small. Got wind power? You might have humpback whales to thank. Know anything about particle physics? Turns out there is a ferret close to the heart of it all. And if you want to keep salmon around, be thankful for that cannon! The research itself can seem bizarre. But it drives our economy. And what’s more, this stuff is simply cool.

York invites readers to appreciate the often unpredictable journey of scientific exploration, highlighting that the heart of science lies in the relentless pursuit of knowledge for its own sake. Emphasizing the hard work of the people behind the discoveries, this is an accessible, story-driven book that shows how important and exciting it is to simply let curiosity run wild.

Transcendental Magic is a classic of occultism, prized for its wide-ranging wisdom, thorough guidance and revelatory contents. Written by Eliphas Levi in the mid-19th century, Transcendental Magic offers seekers of occult knowledge a bounty of guidance and knowledge. Informed by research spanning many centuries of arcane arts, the author offers us profound guidance to the ceremonial rituals one must perform in order to make contact with spirits and other non-corporeal entities of the universe. In Levi's explanations we encounter various figures of occult lore. Monad is synonymous with God; the creator of everything contained in our physical plane. Derived from the Pythagorean school, through Levi we learn how Monad interacts with the creation. This discussion is related to the Kabbalah, which attempts to define the relationship between what is infinite and what is finite.

Practically every display technology in use today relies on the flat, energy-efficient construction made possible by liquid crystals. These displays provide visually-crisp, vibrantly-colored images that a short time ago were thought only possible in science fiction. Liquid crystals are known mainly for their use in display technologies, but they also provide many diverse and useful applications: adaptive optics, electro-optical devices, films, lasers, photovoltaics, privacy windows, skin cleansers and soaps, and thermometers. The striking images of liquid crystals changing color under polarized lighting conditions are even on display in many museums and art galleries - true examples of 'science meeting art'. Although liquid crystals provide us with visually stunning displays, fascinating applications, and are a rich and fruitful source of interdisciplinary research, their full potential may yet remain untapped.
