Book Description
“Both timeless and timely, this is a book of wisdom and wonder” (Geraldine Brooks, Pulitzer Prize–winning author of March), a deeply personal exploration of what can sustain us through our darkest moments. “What has fascinated and sustained me over these last few years has been the notion that we have the ability to find, nurture, and carry our own inner, living light—a light to ward off the darkness. This is not about burning brightly; it’s about yielding a more simple phosphorescence—being luminous, having stored light for later use. Staying alive, remaining upright, even when lashed by doubt.” After surviving a difficult heartbreak and battle with cancer, acclaimed author and columnist Julia Baird began thinking deeply about how we, as people, persevere through the most challenging circumstances. She started to wonder, when we are overwhelmed by illness, loss or pain, or a tragedy outside our control: How can we keep putting one foot in front of the other? Baird went in search of the magic that fuels the light within—our own phosphorescence. In this stunning book, she reflects on the things that lit her way through the darkness, especially the surprising strength found in connecting with nature and not just experiencing awe and wonder about the world around her, but deliberately hunting it, daily. Baird also writes about crossbeams of resilience: nurturing friendships and a quiet faith, pursuing silence, fighting for what she believes in, the importance of feeling small, learning from her mother's example of stoic grace. She also explores how others nurture their inner light, interviewing the founder of the modern forest therapy movement in Tokyo, a jellyfish scientist in Tasmania, and a tattooed priest from Colorado, among others. Weaving together candid and moving memoir with deep research and reflections on nature and the world around her, Baird inspires readers to embrace new habits and to adopt a phosphorescent outlook on life, to illuminate ourselves and our days—even in the darkest times.

Book Description
"After surviving a difficult heartbreak and battle with cancer, Julia Baird began to explore how she and others persevere through the most challenging circumstances life throws at us. She asks: when our world goes dark, when we are overwhelmed by illness or heartbreak, loss or pain, tragedy outside our control, how do we survive, stay alive and even bloom? She went in search of "the magic that will sustain us and fuel the light within - our own phosphorescence ". Phosphorescence can be found in nature - in glow worms, fireflies, flashlight fish, bioluminescent oceans; it is a phenomenon that allows creatures to give off light amidst darkness. Baird writes about the things that lit her way through the darkness: a connection to nature, friendships, her faith, experiencing awe, and other habits that changed her life. She also goes in search of how others nurture their inner light, interviewing the founder of the modern forest therapy movement in Tokyo, a jellyfish scientist in Tasmania, and a tattooed priest from Colorado, among others. Weaving together candid memoir with research and reflections on nature, Baird inspires readers to embrace new habits and adopt a phosphorescent outlook on life, to illuminate our days even in the darkest times"--

Fluorescence and Phosphorescence Spectroscopy

Fluorescence and Phosphorescence Spectroscopy PDF Author: Stephen G Schulman
Publisher: Elsevier
ISBN: 1483160998
Category : Science
Languages : en
Pages : 299

Book Description
Fluorescence and Phosphorescence Spectroscopy: Physicochemical Principles and Practice deals with the physicochemical principles and applications of fluorescence and phosphorescence spectroscopy in experimental biology and chemistry. Topics covered include the absorption of light by molecules; instrumentation for the measurement of fluorescence and phosphorescence; solvent and acidity effects on electronic spectra; and polarization of fluorescence and phosphorescence. Comprised of four chapters, this book begins with a discussion on photophysical processes in isolated molecules and molecules in solution, paying particular attention to thermal equilibration of electronically excited molecules, phototautomerism, and coordination by metal ions. The next chapter describes the instrumentation for measuring fluorescence and phosphorescence, which consists essentially of a light source to electronically excite the sample; a monochromator to separate the light of desired energy from the source; a sample compartment; a second monochromator to isolate the sample's fluorescence energy from the excitation energy; a photodetector to translate the fluorescent light into an electrical signal; and a readout system such as a galvanometer or a recorder, coupled with an amplifier to determine the intensity of fluorescent light that is emitted. The final chapter is devoted to various applications of fluorescence and phosphorescence spectroscopy, including the analysis of organic and inorganic compounds. This monograph is written primarily for analytical chemists and biological scientists.

Book Description
Fourteen-year-old Lola Jordan feels like a useless misfit among her cool city classmates. Until this term she’s lived a quiet country life on the windswept saltmarshes of north Norfolk. She’s mortified when her lyrical essay on phosphorescence is read out in front of the whole school. But much worse is the ensuing geography trip to her childhood home. Camping on the famous island nature reserve run by her father, a bunch of designer-clad teenagers, including the boy of Lola’s dreams, runs wild. But in the midst of chaos, excitement, danger and snogging in the sparkling midnight sea, Lola learns that the best way to belong is to be an individual.
