Light is an element that draws together many areas of human knowledge: physics, chemistry, biology, astronomy, engineering, and art. Moreover, optical phenomena and the technologies based on them are widespread in our daily lives. However, it can be difficult to understand or explain these phenomena. What is light? Where are optics and photonics present in our lives and in nature? What lies behind different optical phenomena? What is an optical instrument? How does the eye resemble an optical instrument? How can we explain human vision?

In The Soul of Desire, psychiatrist Curt Thompson suggests that underneath all our longings is the desire to be known - and what's more, that this fundamental yearning manifests itself in our deep need to make things of beauty, revealing who we are to others. Desire and beauty go hand in hand. The Soul of Desire is a mature, creative work, weaving together neuroscience and spiritual formation to open up new horizons for thinking not only about the nature of the mind but about what it means to be human.

Nicknamed the "Real-Life Lorax" by National Geographic, the biologist, botanist, and conservationist Meg Lowman - aka "CanopyMeg" - takes us on an adventure into the "eighth continent" of the world's treetops, along her journey as a tree scientist, and into climate action. Welcome to the eighth continent! As a graduate student exploring the rain forests of Australia, Meg Lowman realized that she couldn't monitor her beloved leaves using any of the usual methods. So she put together a climbing kit: she sewed a harness from an old seat belt, gathered hundreds of feet of rope, and found a tool belt for her pencils and rulers. Up she went, into the trees. Forty years later, Lowman remains one of the world's foremost arbornauts, known as the "real-life Lorax". She planned one of the first treetop walkways and helps create more of these bridges through the eighth continent all over the world.

Have you ever asked yourself what the purpose of your life is? Do you feel like life is meaningless because you have not encountered a convincing answer to that question? Well, you are not alone. Many philosophers have argued that a clear answer to the problem of meaning is forever lost, and that there is no rational way to secure purpose. If a solution could be discovered, it would only be a very subjective one. We may construct one for ourselves, according to this line of thinking, but an objective purpose can never be found. I wrote this book because I strongly disagree with this contention.

For millenia humans have considered Mars the most fascinating planet in our solar system. We've watched this Earth-like world first with the naked eye, then using telescopes, and, most recently, through robotic orbiters and landers and rovers on the surface.

Discovering Abstract Algebra takes an Inquiry-Based Learning approach to the subject, leading students to discover for themselves its main themes and techniques. Concepts are introduced conversationally through extensive examples and student investigation before being formally defined. Students will develop skills in carefully making statements and writing proofs, while they simultaneously build a sense of ownership over the ideas and results. The book has been extensively tested and reinforced at points of common student misunderstanding or confusion, and includes a wealth of exercises at a variety of levels. The contents were deliberately organized to follow the recommendations of the MAA's 2015 Curriculum Guide. The book is ideal for a one- or two-semester course in abstract algebra, and will prepare students well for graduate-level study in algebra.
