Conservationist Rachel Carson spent over six years documenting the effects on DDT, a synthetic organic compound used as an insecticide, on numerous communities. Her analysis revealed that such powerful, persistent chemical pesticides have been used without a full understanding of the extent of their potential harm to the whole biota, including the damage they've caused to wildlife, birds, bees, agricultural animals, domestic pets, and even humans. An instant best seller that was read by President Kennedy during the summer of 1962, this classic remains one of the best introductions to the complicated and controversial subject.

On October 12, 1972, a plane carrying a team of young rugby players crashed into the remote, snow-peaked Andes. Out of the 45 original passengers and crew, only 16 made it off the mountain alive. For 10 excruciating weeks, they suffered deprivations beyond imagining, confronting nature head-on at its most furious and inhospitable. And to survive, these men and women not only had to keep their faith; they had to make an impossible decision: Should they eat the flesh of their dead friends?

In this lecture, Professor Kahn will examine the state of health care and biomedical research in the US and around the globe, through the lens of ethics. The lecture will start with some historical context and examples from bioethics, and draw some parallels from the past for the current state of our public discussions on a range of controversial bioethics issues.

Nearly everyone is familiar with holograms - three-dimensional images projected into space with the aid of a laser. Two of the world's most eminent thinkers believe that the universe itself may be a giant hologram, quite literally a kind of image or construct created, at least in part, by the human mind. University of London physicist David Bohm, one of the world's most respected quantum physicists, and Stanford neurophysiologist Karl Pribram, an architect of our modern understanding of the brain, have developed a remarkable new way of looking at the universe.

Breakthroughs in genetics present us with a promise and a predicament. The promise is that we will soon be able to treat and prevent a host of debilitating diseases. The predicament is that our newfound genetic knowledge may enable us to manipulate our nature - to enhance our genetic traits and those of our children. Although most people find at least some forms of genetic engineering disquieting, it is not easy to articulate why.

Why is the genome of a salamander 40 times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because we’ve embraced a faulty conception of how evolution - and human society - really works.

Including letters, speeches, articles, and essays written before 1935, this collection offers a complete portrait of Einstein as a humanitarian and as a human being trying to make sense of the world changing around him.

Longevity: the ambition of kings, super villains, and pretty much all of us who enjoy waking up each morning. It's also become a focus for biotechnology companies interested in making a big impact on healthcare. According to Professor Jill Helms, questions of this magnitude require moonshot thinking and some extreme team science. In this lecture, she will explain how her Stanford group is working to better understand why we age and translating that knowledge into strategies that slow this natural process.

Narratives about decision making are often inadvertently tailored primarily to men. Meanwhile, narratives about women in business overlook decision making or offer advice that is unhelpful and can even backfire. How Women Decide fills this gap. It takes on the very real psychological and cultural obstacles women face, asks how these affect decision making, and suggests practical changes for approaching important choices.

Noted transcendentalist Henry David Thoreau spent two years, two months, and two days chronicling his near-isolation in the small cabin he built in the woods near Walden Pond on land owned by his mentor, the father of Transcendentalism, Ralph Waldo Emerson. Immersing himself in nature and solitude, Thoreau sought to develop a greater understanding of society amidst a life of self-reliance and simplicity. Originally published in 1854, Walden remains one of the most celebrated works in American literature.

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.

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.

We know that plants are important. They maintain the atmosphere by absorbing carbon dioxide and producing oxygen. They nourish other living organisms and supply psychological benefits to humans as well, improving our moods and beautifying the landscape around us. But plants don’t just passively provide. They also take action. Beronda L. Montgomery explores the vigorous, creative lives of organisms often treated as static and predictable.

In the middle of New York City lies a neighborhood where all secrets are valuable, all assets are liquid, and all deals are sealed with a blessing rather than a contract. Welcome to the diamond district. Ninety percent of all diamonds that enter America pass through these few blocks, but the inner workings of this mysterious world are known only to the people who inhabit it.

Built of titanium and a chrome-nickel alloy known as Inconel X, the X-15 was the fastest plane ever built, streaking through the lower reaches of outer space even before the first space capsules reached orbit. First tested in 1959, the X-15 proved to be a crucial testing ground for the astronauts and hardware in the Mercury, Gemini, Apollo, and even the Space Shuttle programs. Celebrated reporter Richard Tregaskis spent time with the pilots, engineers, and other key personnel involved in the project.

Edison and Tesla were arch-enemies with competing visions as to how to electrically empower America. Their hostility played out in the infamous War of the Currents. Radio, television, robots, electric cars, self-driving cars, solar heating, the internet, and the cellphone were on the mind of one or the other of these geniuses. Which one ultimately proved to have the more accurate and enduring vision for the world? Who is in the news today and why? Come and find out the answers.

When the struggle to save oil-soaked birds and restore blackened beaches left him feeling frustrated and helpless, John Francis decided to take a more fundamental and personal stand: He stopped using all forms of motorized transportation. Soon after embarking on this quest that would span two decades and two continents, the young man took a vow of silence that endured for 17 years.

On the evening of April 13, 1970, the three astronauts aboard Apollo 13 were just hours from the third lunar landing in history. But as they soared through space, 200,000 miles from Earth, an explosion badly damaged their spacecraft. Thirteen is the shocking and miraculous true story of how the astronauts and ground crew guided Apollo 13 back to Earth. Expanding on dispatches written for The New Yorker, Henry S. F. Cooper Jr. brings listeners unparalleled detail on the moment-by-moment developments of one of NASA’s most dramatic missions.
