Turn on the light on science by Antonio Tintori,Rossella Palomba Pdf

Scientists deserve public recognition. The ways that they are depicted, however, are severely limited in physical and personal traits, helping to establish and enhance stereotypes under the general title of ‘scientist’. These stereotypes range from the arrogant researcher who wants to rule the world, to the lab coat wearing ‘nerdy’ genius, but all generally fall to an extreme view of an existing perception of what a scientist should look and be like. For example, the popular image of ‘a scientist’ overlooks the presence of women almost entirely unless attributed to specific subjects and/or with narrow character depictions. The implications can be far-reaching. Young people, being heavily swayed by what they see and hear in the media, may avoid scientific careers because of these limited or unflattering portrayals of the scientific community, regardless of whether they reflect real life. Based on findings from the Light’13 project, this book examines such stereotypes and questions whether it is possible to adjust people’s perception of scientists and to increase interest in science and scientific careers through a series of specific actions and events.

A Light in Dark Times by Judith Friedlander Pdf

The New School for Social Research opened in 1919 as an act of protest. Founded in the name of academic freedom, it quickly emerged as a pioneer in adult education—providing what its first president, Alvin Johnson, liked to call “the continuing education of the educated.” By the mid-1920s, the New School had become the place to go to hear leading figures lecture on politics and the arts and recent developments in new fields of inquiry, such as anthropology and psychoanalysis. Then in 1933, after Hitler rose to power, Johnson created the University in Exile within the New School. Welcoming nearly two hundred refugees, Johnson, together with these exiled scholars, defiantly maintained the great traditions of Europe’s imperiled universities. Judith Friedlander reconstructs the history of the New School in the context of ongoing debates over academic freedom and the role of education in liberal democracies. Against the backdrop of World War I and the first red scare, the rise of fascism and McCarthyism, the student uprisings during the Vietnam War and the downfall of communism in Eastern Europe, Friedlander tells a dramatic story of intellectual, political, and financial struggle through illuminating sketches of internationally renowned scholars and artists. These include, among others, Charles A. Beard, John Dewey, José Clemente Orozco, Robert Heilbroner, Hannah Arendt, and Ágnes Heller. Featured prominently as well are New School students, trustees, and academic leaders. As the New School prepares to celebrate its one-hundredth anniversary, A Light in Dark Times offers a timely reflection on the legacy of this unique institution, which has boldly defended dissident intellectuals and artists in the United States and overseas.

Light Science by Thomas D. Rossing,Christopher J. Chiaverina Pdf

Intended for students in the visual arts and for others with an interest in art, but with no prior knowledge of physics, this book presents the science behind what and how we see. The approach emphasises phenomena rather than mathematical theories and the joy of discovery rather than the drudgery of derivations. The text includes numerous problems, and suggestions for simple experiments, and also considers such questions as why the sky is blue, how mirrors and prisms affect the colour of light, how compact disks work, and what visual illusions can tell us about the nature of perception. It goes on to discuss such topics as the optics of the eye and camera, the different sources of light, photography and holography, colour in printing and painting, as well as computer imaging and processing.

Matches by S. D. Chrostowska Pdf

It takes any number of forms. Epigrams. Aphorisms. Fragments. Sayings. Dicta. Sententiae. Facetiae. Pearls of wisdom. Fractions of truth. Maxims. Definitions. Jottings. Miscellaneous musings. Meditations. Ricordi. Pensées. Ephemera. Miniatures. Sketches. Vignettes. Denkbilder. Capriccios. Tiny 'fires without flames' ... In returning to these genres, Matches goes back to the drawing board of modern critique. It sets out to rekindle short-form literary-philosophical reflection, with roots in the Antiquity of Heraclitus and Hippocrates, apogee in the French moralistes (La Rochefoucauld, Pascal, Chamfort ...), and late splendour in German letters (Nietzsche, Kraus, Jünger ...). Moving from art and aesthetics to philosophies past and present, through natural and technological landscapes, beneath the constellations of politics, history and ethics, along the byways of contemporary literary culture--the slow reader with a little spare time will not fail to be struck. Here are pages to peruse and mistrust, texts to think with, a book to put down and ponder, to ponder and put down. A tome to keep handy, handle often, and strike repeatedly against the rough patches of the mind.

Run in the Light by John Mitrofanis Pdf

Parkinson's disease is a neurological disorder with cardinal motor signs of resting tremor, bradykinesia and lead-pipe rigidity. In addition, many patients display non-motor symptoms, including a diminished sensation of smell, gastrointestinal problems, various disorders of sleep and some cognitive impairment. These clinical features - particularly the motor signs - manifest after a progressive death of many dopaminergic neurones in the brain. Although currently available, conventional therapies can reduce the signs of the disease, the progression of this neuronal death has proved difficult to slow or stop, and the condition is relentlessly progressive. Hence, there is a real need to develop a treatment that is neuroprotective, one that slows the pathology of the disease effectively. At present, there are several neuroprotective therapies in the experimental pipeline, but these are for the patients of tomorrow. This book focuses on two therapies that are readily available for the patients of today. They involve the use of exercise and light (i.e. photobiomodulation, the use of red to infrared light therapy (λ=600-1070nm) on body tissues). The two therapies are tied together in several ways. First, in animal models of Parkinson's disease, they each have been shown to offer the key feature of neuroprotection, stimulating a series of built-in protective mechanisms within the neurones, that helps their survival, to self-protect and/or self-repair. There are also some promising indications of neuroprotection and many beneficial outcomes in parkinsonian patients. Further, both exercise and light therapies are similar in that they are non-invasive and safe to use, with no known adverse side-effects, making their combination with the conventional therapies, such as dopamine replacement drug therapy and deep brain stimulation, all the more feasible. Given the heterogeneity of Parkinson's disease in humans, tackling the condition from a range of different angles - with a number of different therapies - would only serve to enhance the positive outcomes. This book considers the use of exercise and light therapies, proposing that they have the potential to make a powerful "dynamic duo", offering a most effective neuroprotective treatment option to patients.

The Light Ages: The Surprising Story of Medieval Science by Seb Falk Pdf

Named a Best Book of 2020 by The Telegraph, The Times, and BBC History Magazine An illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk. "Falk’s bubbling curiosity and strong sense of storytelling always swept me along. By the end, The Light Ages didn’t just broaden my conception of science; even as I scrolled away on my Kindle, it felt like I was sitting alongside Westwyk at St. Albans abbey, leafing through dusty manuscripts by candlelight." —Alex Orlando, Discover Soaring Gothic cathedrals, violent crusades, the Black Death: these are the dramatic forces that shaped the medieval era. But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks. As medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky, they came to develop a vibrant scientific culture. In The Light Ages, Cambridge science historian Seb Falk takes us on a tour of medieval science through the eyes of one fourteenth-century monk, John of Westwyk. Born in a rural manor, educated in England’s grandest monastery, and then exiled to a clifftop priory, Westwyk was an intrepid crusader, inventor, and astrologer. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk and travel with him through the length and breadth of England and beyond its shores. On our way, we encounter a remarkable cast of characters: the clock-building English abbot with leprosy, the French craftsman-turned-spy, and the Persian polymath who founded the world’s most advanced observatory. The Light Ages offers a gripping story of the struggles and successes of an ordinary man in a precarious world and conjures a vivid picture of medieval life as we have never seen it before. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

The Northern Light by A. Brekke,A. Egeland Pdf

In Nordic literature a remarkable discussion of the northern light appears in Kongespeilet (The King's Mirror) a thirteenth-century Norwegian chronicle. It is described in vivid detail as the following translated excerpts demonstrate: These northern lights have this peculiar nature, that the darker the night is, the brighter they seem, and they always appear at night but never by day, most frequently in the densest darkness and rarely by moonlight. In appearance they resemble a vast flame of fire viewed from a great distance. It also looks as if sharp points were shot from this flame up into the sky; these are of uneven height and in constant motion, now one, now another darting highest; and the light appears to blaze like a living flame. Three different theories for the origin of the northern light were suggested in this book. Numerous naturally occurring heavenly phenomena have been observed and enjoyed as long as the Earth has been inhabited, but hardly any of them has stirred man's imagination, curiosity and fear as much as the northern light. The northern light is certainly one of the most spectacular of nature's phenomena.

Patterns of Light by Steven Beeson,James W. Mayer Pdf

Any student or engineer working in optics or the field of laser technology will find this a fascinating read. The book begins by addressing the properties of light as seen in the everyday world: events such as refraction in a pool, lenses in the form of glasses, the colors of objects, and atmospheric events. Latter chapters explain these events at the atomic and subatomic level and address the use of electron and optical microscopy in observing the worlds unseen by the unaided eye. Exercises and activities will be found in an appendix, but the primary volume can stand alone if the reader so desires.

Light Therapies by Anadi Martel Pdf

A comprehensive guide to the therapeutic benefits of light and color and how they affect our physical and psychological well-being • Shares scientific research on how different wavelengths of light influence our cells, brain function, sleep patterns, and emotional stability • Examines several forms of light therapy, including chromotherapy, heliotherapy, actinotherapy, and thermotherapy • Explains how to use light and color therapy, maximize the benefits of sunlight, and avoid the health risks of new light sources such as compact fluorescents and LEDs Beginning with sun worship in prehistory and sunshine therapies in ancient Egypt, Greece, and India, light has long been associated with the sublime, the divine, and healing. Yet only recently have we begun to understand how different parts of the light spectrum, from infrared to ultraviolet, can affect our physical and psychological well-being. Covering the historic, scientific, and spiritual aspects of light and its role in energy medicine, Anadi Martel explores the vibrational nature of light and the interaction between light, biology, and consciousness. He demonstrates light’s incredible effects on the physical, energetic, and cognitive dimensions of life and examines several forms of light therapy, including chromotherapy (color therapy), heliotherapy (sun therapy), actinotherapy (ultraviolet therapy), and thermotherapy (infrared therapy). He details how to use light therapy daily, get optimal benefits from sunlight, and avoid the health risks of new artificial lighting such as compact fluorescents and LEDs. Combining his own 30 years of research with practical insight from the many phototherapy pioneers he’s encountered, the author examines scientific studies on how specific wavelengths of light influence our cells and DNA, brain function, sleep patterns, and emotional stability; speed the healing of wounds; and are effective in the treatment of disease, including arthritis, stroke, Alzheimer’s, Parkinson’s, and brain and nerve injuries. Exploring the spiritual aspects of light, the author explains why auras and halos have been used to represent sages and saints of all traditions, revealing the intimate link between light and consciousness. Investigating the many laser, monochrome, audiovisual, and infrared machines designed to heal disease and treat emotional disorders, Martel also reveals promising medical applications for light that are currently in development, inviting the reader not only to appreciate the complexities of light but to maximize its therapeutic dimensions.
