Book Description
Iridescent fabric shimmers and glows, changing colors depending on how the light hits it. Different colors appear in the folds and pleats, adding surprising layers of color to fabric. To the uninformed it appears magical and difficult, but the truth is that weaving iridescent fabric is accessible to any handweaver who knows the tricks. Bobbie Irwin has been teaching the techniques for weaving iridescence in person and through articles for more than ten years. In this book, she delivers her most comprehensive course yet, covering the details from how to evaluate and choose yarn to achieve your desired effect to the ways weave structure affects iridescence to the best uses for your iridescent fabric. Hands-on project instructions will have you exploring what you've learned right away. If you have been looking to add some shimmer to your weaving, this is the only book you will ever need!

Book Description
A remarkable aspect of this book is its combination of art and science. The author, an accomplished professional artist in the field of natural history, particularly in drawings of birds and insects, is the daughter of a scientist who specialized in optics and was an authority on light interference, the optical phenomenon which plays an important role here. It was this background which enabled the author to approach the subject in a refreshingly original way. What makes a blue bird blue? Why is its color fundamentally different from that of a red bird? What causes the iridescence of a hummingbird's throat? of a peacock's train? of a Morpho butterfly's wings? Why do so many brightly colored birds in museum collections soon fade to a dim washed-out hue, while the hummingbird and the peacock retain their brilliance almost indefinitely? Here we touch on the fundamental difference between structural and pigmentary, physical and chemical colors - a difference which is the main theme of this book - and the various ways in which these structural colors are produced in the tissues of living beings. Also unusual are the means and method of illustration and reproduction. Most illustrators desiring colored reproductions of their art paint colored pictures, and then turn these paintings over to the engraver or lithographer, who uses elaborate cameras with filters to separate the colors so that they can be printed in different inks. Instead of relying on mechanical filters, Hilda Simon translates in her mind each color into the percentages of its component colors. She then prepares in black pencil one separation for each of the four or five colors used in her illustrators. The results are astonishing and original. She has captured some of the most elusive colors as no other process can. Here are to be found, in scientific analysis and microscopic detail of feather structure as well as in all their glory, birds of all sorts from hummingbirds and sunbirds to peacocks, the fabled birds of Juno, and birds of paradise. Here we see the quetzal, symbol of ancient Aztec royalty and emblem of modern Guatemala. Here is a glittering array of iridescent tropical butterflies and moths, golden beetles that gleam like living embers, multicolored fish, shimmering opalescent shells, and even rainbow-hued snakes. -- from dust jacket.

Book Description
In almost every part of the world, the Dragonfly symbolizes change, transformation, adaptability, and self-realization.This book is a collection of poems that poured out from my feelings and life experiences into words. Each poem depicts a different phase of my life - the loss of my mother who was my soul mate, the grieving, spiritual growth and an inner journey that ensued. While a sense of acceptance and peace followed, life threw up another challenge. Even though I was healthy and hearty , I suddenly had a stroke and partial palsy. Many of my later writings in the book reflect the healing journey and the physical and emotional challenges that came with it. The recovery process included huge amounts of physical and emotional healing. This meant a lot of introspection and retrospection: dealing with a lot of emotions from my younger days, memories from the past, acknowledging them, and sitting with them, nurturing some and bringing others to some sort of a closure. What emerged was a stronger, peaceful and creative soul writing this book.The dragonfly is a metaphor of spiritual growth and to be accepting of who you really are and owning it. Its iridescent wings display a spectrum of colours that shimmer and change due to interference and scattering as the observer's position changes, much like life. If seen mindfully, the smallest of things around us can give us the highest meaning of our purpose here. If you are on a spiritual process and journey, then this book is just perfect you.

Book Description
Unlike most natural colours that are based on pigment absorption, the striking iridescent and intense colouration of many butterflies, birds or beetles stems from the interaction of light with periodic sub-micrometer surface or volume patterns, so called “photonic structures”. These “structural colours” are increasingly well understood, but they are difficult to create artificially and exploit technologically. In this thesis the field of natural structural colours and biomimetic photonic structures is covered in a wide scope, ranging from plant photonics to theoretical optics. It demonstrates diffractive elements on the petal surfaces of many flowering plant species; these form the basis for the study of the role of structural colours in pollinator attraction. Self-assembly techniques, combined with scale able nanofabrication methods, were used to create complex artificial photonic structures inspired by those found in nature. In particular, the colour effect of a Papilio butterfly was mimicked and, by variation of its design motive, enhanced. All photonic effects described here are underpinned by state-of-the-art model calculations.
