What’s out there in the vast reaches of space? Are we alone in the universe? Renowned astronomer Carl Sagan offers some insight into these questions and many more in his widely acclaimed book, Cosmos.

Sagan is a Pulitzer Prize-winning author and perhaps the greatest astronomer of our age. In this book, he provides a comprehensive description of the science, philosophy, and history of astronomical discovery, from ancient Ionia to the time of the book’s publication in 1980.

In this guide, we’ll delve into Sagan’s theories about the possibility of interstellar travel, the search for extraterrestrial life, and man’s quest for understanding the mysteries of the universe. As we go along, we’ll update the information with the most recent scientific discoveries and provide perspectives from other experts in related fields.

Imagine that men and women come from two different planets. When you think that way, it’s suddenly easier to understand why men and women tend to communicate differently, behave differently, and have different emotional needs.

In this book, author John Gray breaks down the primary differences between men and women and gives comprehensive advice for dealing with miscommunication, showing support to your partner in the way they crave, and being more fulfilled with your relationship. Find out why your husband pulls away just when you need him most, and why your wife needs to talk relentlessly about her feelings.

The human race has left a mark on our planet, sometimes through carelessness and sometimes by design, but how permanent are the changes we’ve made? In The World Without Us, science journalist Alan Weisman asks what would happen if the human race vanished overnight. What effects, positive or negative, would our disappearance have on the world? Weisman’s goal is to address humanity’s environmental impact by imagining a world in which nature is allowed to flourish. In many ways, the world that follows us would be significantly different than what came before.

In this guide, we’ll examine Weisman’s portrayal of humanity’s footprint and what Weisman claims would happen if we suddenly disappeared. Also, we’ll look at other views on climate change, nature’s resilience, and the human race’s impact. We’ll list suggestions for how our species might adapt to a greener world, as well as scenarios that might cause our extinction.

Warming winters affect everything from crop production to road building, and this article looks at the effects of rising temperatures on a variety of regions in the United States.

Climate change-driven heat waves, flooding, and droughts are plaguing the globe. What’s worse, the extreme weather events are exceeding climate scientists’ projections—which suggests we’re unprepared for what’s to come. It’s too late to reverse the effects of climate change. All we can do is to keep things from getting worse and adjust to our new normal with adaptations like green technology, updated building codes, and better infrastructure. Private industry is getting more involved with adaptation efforts, as it’s becoming increasingly clear that severe weather will impact business.

Aside from causing extreme weather events and the loss of polar bear habitats, climate change has other effects that have a direct impact on your day-to-day life: hotter tempers, lower productivity, and even a future without your morning coffee.

A Victorian scientist builds a machine that can travel through time. In the distant future he finds that, rather than advancing, human civilization has totally collapsed. The Time Machine, first published in 1895, is one of the earliest known science fiction stories. This literary classic by English author H.G. Wells popularized the concept of time travel and introduced the now-common phrase “time machine.”

This guide will organize The Time Machine into four sections. It begins with the Time Traveller showing off the time machine he invented. He journeys into the future, where humanity has evolved into the childlike Eloi and the bestial Morlocks. He then goes even further into the future and sees the end of the world. Finally, he goes back home to tell his friends what he’s seen. Our commentary will discuss the science behind the story, including which concepts are real and which are fiction. It will also discuss the literary techniques and symbolism Wells used to craft this story.

How much do you know about the universe you live in? Thanks to scientific discoveries of the twentieth century, scientists have gained insight into many of nature’s secrets, from the origin of the universe to the nature of space and time. In A Brief History of Time, physicist Stephen Hawking explains these insights for a general audience.

In this guide, we’ll present Hawking’s exposition of modern physics through the lens of five big questions that the book answers: Is reality relative or absolute? Is the future predetermined? How did the universe begin? What is the nature of a black hole? And can you build a time machine? Where applicable, we’ll also examine how Hawking’s assertions and predictions stack up to new data that scientists have collected since the book was published.

The rapid pace of technological change has impacted our lives and our world in many ways, and our headlong rush into the future may have staggering implications for our species. In The Singularity Is Near, computer scientist Ray Kurzweil predicts that a profound technological shift will change everything about how we live, how society functions, and even what it means to be human. From using genetics to reprogram the body to having the power to digitally augment our brains, the technological Singularity will lead to a future in which even death may one day be forgotten.

In this guide, we’ll explore the ongoing revolutions that together may overturn our current order—bioscience, nanotechnology, and artificial intelligence. We’ll examine Kurzweil’s predictions for these technologies, as well as some of their potential dangers. As the book was published in 2005, we’ll also look at how well Kurzweil’s predictions hold up and the different paths that some technologies have taken.

Why does life work the way it does? Are life’s features the product of random genetic mutations, or did organisms have to evolve a certain way to overcome specific physical and chemical challenges? In The Vital Question, Nick Lane argues that genetics can’t give us the answer by itself. To explain the origin of life, we have to understand how cells make use of energy and what environmental conditions gave rise to the molecular power plants found in every living thing.

In this guide, we’ll explore the biochemistry of cells and how it may have developed on the very young Earth. We’ll explain why Lane believes all complex life emerged from a single instance of symbiosis between two very different single-celled creatures. We’ll expand on fundamentals of biology and genetics, discuss alternate views to some of Lane’s proposals, and point to the directions research is now taking to gain a fuller understanding of life’s origins.
