Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

Chemistry and Our Universe: How It All Works is your in-depth introduction to this vital field, taught through 60 engaging half-hour lectures that are suitable for any background or none at all. Covering a year’s worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this amazingly comprehensive course requires nothing more advanced than high-school math. Your guide is Professor Ron B. Davis, Jr., a research chemist and award-winning teacher at Georgetown University.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

In this 24-lesson course aimed at non-scientists, noted particle physicist Dr. Don Lincoln of Fermi National Accelerator Laboratory covers more than a century of progress in physics, describing exactly how scientists reach the conclusions they do. He starts with the atom, which was long hypothesized but wasn’t definitively proven until a paper by Albert Einstein in 1905. That was just the beginning, as researchers probed ever deeper into the atom’s complex structure, leading to the weird findings of quantum mechanics.

No skill is more important in today's world than being able to think about, understand, and act on information in an effective and responsible way. What's more, at no point in human history have we had access to so much information, with such relative ease, as we do in the 21st century. But because misinformation out there has increased as well, critical thinking is more important than ever. These 24 rewarding lectures equip you with the knowledge and techniques you need to become a savvier, sharper critical thinker in your professional and personal life.

Cultivating herbs for medical use is an ancient and powerful practice—ginger to boost your immune system, basil to ease your morning sickness, garlic to soothe your child’s cough—all these are there in your own kitchen closet. Plus, you can have 71 more science-backed ailments and their remedies in your backyard at your fingertips. But that’s just the beginning…your body’s natural wisdom is just waiting to be unlocked. But our modern, harsh chemicals can block that potential from ever being realized.

Sajah Popham presents an innovative approach to herbalism that considers the holistic relationship among plants, humans, and the underlying archetypal patterns in Nature. Organized in five parts moving from the microcosmic to the universal, this work explores a unique integration of clinical herbalism, Ayurveda, medical astrology, spagyric alchemy, and medical and esoteric traditions from across the world into a truly holistic system of plant medicine.

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

Most gardeners realize that plants need to be fed but know little to nothing about the nature of the nutrients involved or how they get into plants. Teaming with Nutrients explains how nutrients move into plants and what both macro-nutrients and micro-nutrients do once inside. It shows organic gardeners how to provide these essentials.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

Almost every plant in a garden forms a relationship with fungi, and many plants would not exist without their fungal partners. By better understanding this relationship, home gardeners can take advantage of the benefits of fungi, which include an increased uptake in nutrients, resistance to drought, earlier fruiting, and more. This must-have guide will teach you how fungi interact with plants and how to best to employ them in your home garden.

Do you wish for a more resilient, sustainable, and empowered way of providing for your family in uncertain times? Are you worried about unreliable power grids, uncertain water supplies, or overly complex food chains? Veteran homesteader and star of Discovery's Homestead Rescue Marty Raney shares a big-picture vision of how ordinary families can become radically resilient homesteaders: powering, feeding, and caring for themselves through their own efforts, and on their own land.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

When we use chemical fertilizers, we injure the microbial life that sustains plants and then become increasingly dependent on an arsenal of toxic substances. Teaming with Microbes offers an alternative to this vicious circle and details how to garden in a way that strengthens, rather than destroys, the soil food web. You’ll discover that healthy soil is teeming with life - not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms.

The audio is focused and high-yield, covering the most important topics you might expect to learn in a typical undergraduate anatomy and physiology course. The material is accurate, up-to-date, and broken down into bite-sized chapters. There are key takeaways following each chapter to drive home key points and quizzes to review commonly tested questions.
